Foreword

Successful military organizations are solidly founded upon the pride of their members and soldiers with a strong sense of belonging to their unit and enthusiastic about its being their own. Good military leaders always strive to attain this intangible quality, generally known as esprit de corps. Anything that helps an army to achieve it contributes to better units.

As the authors trace the evolution of cavalry into today's armor branch, their narrative presents a broad history of the growth of the entire U.S. Army. It gives an insight into the reasoning and considerations behind most of the organizational changes the Army has undergone, lending clarity and perspective to the unit lineages that follow.

The Army Lineage Series is designed to foster the esprit de corps of United States Army units. It is intended for use at all levels of command, in service schools, and in various training programs. Armor-Cavalry, the second volume in the series, is designed as a tool to perpetuate the rich tradition of cavalry and the brilliant record of modern armor.

History of the Organization of the Armor and Cavalry

Revolutionary War

At the time of the American Revolution, the term cavalry was applied to that branch of the military service whose members served and fought on horseback; the word horse was used about as often and meant essentially the same thing. By the eighteenth century specialization had developed sufficiently in cavalry to bring forth three distinctive types of mounted commands, varying in mission, armament, and weight of horses: the heavy cavalry, used primarily for shock effect in battle; the light cavalry, designed for reconnaissance, screening missions, and messenger service; and the dragoons, trained to fight both on foot and on horse. In actual practice, these distinctions were far from precise, and they tended to decrease in importance in the nineteenth century. In North America, the traditional cavalryman has ever been the light dragoon- a soldier trained and equipped to fight mounted or dismounted, to perform screening and reconnaissance, and to act as a scout or messenger. True heavy and true light horse have been rare.

The Continental Army of the American Revolution was mainly composed of infantry, with very little artillery and cavalry. In 1774, on the eve of the Revolution, some colonies had volunteer mounted units of troop size, but these troops were as much social organizations as military commands. They had select memberships who elected their own officers, furnished their own horses, arms, and uniforms, and made their own regulations.

The Continental Army fought through 1775 and 1776 with a few of the mounted militia commands as its only cavalry. Outstanding among these organizations was the Light Horse of the City of Philadelphia, a troop organized in November 1774 and today still active in the Army National Guard as Troop A, 1st Squadron, 223d Cavalry (First Troop Philadelphia City Cavalry). That tiny organization served as General Washington's escort in 1775 and in the bitter days of Trenton and Princeton, displaying then, as later in the war, "a Spirit of Bravery which will ever do Honor to them and will ever be gratefully remembered by me," to quote their Commander in Chief. Another such troop

4

was the Connecticut Light Horse commanded by Elisha Sheldon. It, too, had elicited Washington's praise for its service in the summer of 1776.

General Washington's experience with cavalry in the summer campaign of 1776 led him to recommend the establishment of one or more mounted units in the Continental Army, and Congress on 12 December 1776 constituted a regiment of light dragoons and appointed Elisha Sheldon of Connecticut as its commander. Congress also authorized Washington to appoint the other officers of the regiment, but he delegated the duty to Sheldon, reserving for himself the right to refuse any officer so appointed if he thought him unfit for cavalry service. Washington indicated that he expected Sheldon to appoint only gentlemen of "true spirits and good character" and observed that gentlemen of fortune and of reputable families generally made the most useful officers.

In accordance with General Washington's instructions, the new regiment was to have, besides Sheldon as its lieutenant colonel commandant, one other field officer, a major; a regimental staff of an adjutant, a surgeon, and a surgeon's mate; and 6 troops. Each troop was to consist of a captain, a lieutenant, a

5

cornet,* a quartermaster, 2 sergeants, 2 corporals, a trumpeter, a farrier, and 34 privates.

On 27 December 1776, Congress authorized a total of 3,000 light horse. During the winter and the spring of 1777 the Army began organizing four regiments: the 1st Continental Light Dragoons (Bland's Horse), the 2d Continental Light Dragoons (Sheldon's Horse), the 3d Continental Light Dragoons (Baylor's Horse), and the 4th Continental Light Dragoons (Moylan's Horse).

In January 1777 Washington proposed a new plan of organization for the cavalry regiments. As approved by Congress on 14 March of the same year, the new organization called for a colonel, a lieutenant colonel, and a major as field officers; a chaplain, a regimental quartermaster, a surgeon, a surgeon's mate, a paymaster, a riding master, a saddler, a trumpeter major, an adjutant, and 4 supernumeraries on the staff; and a captain, a lieutenant, a cornet, a quartermaster sergeant, an orderly or drill sergeant, a trumpeter, a farrier, an armorer, 4 corporals, and 32 privates in each of the 6 troops.

Although Congress authorized an increase in the strength of the light dragoon regiments in 1778, constant difficulties in recruiting men, procuring horses, arms, and accouterments, and retaining the men once they enlisted kept the four regiments from ever reaching full strength. When Friedrich Wilhelm, Baron von Steuben, Inspector General of the Army, inspected the cavalry in 1780 he found only 1,000 men in all. In the same year Washington and Steuben therefore recommended that the four understrength cavalry regiments be converted to legions-organizations composed of both cavalry and infantry. To back up his recommendation, Washington cited the high cost of horses and forage and the need of mounted troops to work in conjunction with foot soldiers. Another factor influencing the organization of legions was the dragoons' limited firepower. The dragoons were armed with heavy sabers, flintlock pistols carried in saddle holsters, and, when they were available, carbines." Because of the shortage of carbines, the dragoons lacked the protection of long-range firearms and thus were unable to defend their own camps during attacks. Infantrymen therefore had to be assigned to duty with the dragoons to protect them. Cavalry (and armor) throughout modern history have normally worked with infantry in battle. The legion as an organization thus seemed to be a logical solution to one of Washington's organizational problems.

Congress complied with Washington's recommendation on 21 October 1780, directing that a legion would consist of four troops of mounted dragoons and two companies of dismounted dragoons. The men of the dismounted companies were to be armed as light infantry.

* The rank of cornet was the lowest commissioned officer rank in the dragoons of the time. Cornet in the dragoons was the equivalent of ensign in the infantry. In 1799 both ranks were abolished in the Regular Army and replaced by that of second lieutenant. Cornet, as a rank, survives today in the First Troop Philadelphia City Cavalry of the National Guard.
** The carbine of that period was a short-barreled, smoothbore shoulder arm.

The legionary organization was retained to the end of the war. Outstanding leaders of the legions included Henry (Light Horse Harry) Lee, William Washington, Charles Armand (the Marquis de la Rouerie), and Count Casimir Pulaski. Pulaski, by virtue of his appointment as "Commander of the Horse" in September 1777, is often referred to as the first Chief of Cavalry of the United States Army.

By 1780 the center of the war had shifted to the southern states, but large British commands remained in the north. The four, dragoon regiments were split between the areas. In the north, they never again saw service as regiments, but special commands drawn from them raided strongholds and supply lines in New York and Long Island. On 9 November 1782, the 1st and 3d Continental Light Dragoons, then in the south, were consolidated to form Baylor's Dragoons. And when the war ended the regiments that had served in the south together could muster less than two hundred men.

Other mounted organizations figured prominently in the war. In the south were the commands of Francis Marion, Thomas Sumter, and Andrew Pickens. These partisan units were small organizations that operated independently and usually fought on foot, using their horses chiefly for transportation. Mounted frontiersmen were especially effective in the Battles of King's Mountain (October 1780) and Cowpens (January 1781) in the Carolinas. In the Battle of Guilford's Court House in March of 1781, Washington's dragoons and those of Henry Lee's legion fought mounted, Lee's dragoons having the first encounter with the enemy.

When the American Revolution came to an end in 1783, the remaining fragments of the Continental Cavalry were discharged. During the next fifty years mounted organizations existed in the Regular Army only for brief periods and then only as a very small part of the Army. The first such unit, a squadron of dragoons added in 1792, was broken up even before it was organized. Its four companies were assigned one each to the four sublegions that comprised the Legion of the United States. When that organization was abandoned in 1796, the Army returned to a regimental-type organization and the mounted portion was reduced to two companies. Two years later, when American relationships with France became strained, Congress authorized six new dragoon companies for service during the period of the differences between the two countries. The six new companies, together with the old ones, were to have formed a regiment of light dragoons, but for reasons of economy the new companies were never organized. Although the company officers were appointed, no enlisted dragoons were enrolled and no horses provided. In 1800 the two old companies were dismounted and two years later they, too, were disbanded.

For six years thereafter the Regular Army had no cavalry. From 1783 on, however, volunteer troops of horse existed in all the states. All volunteer militia organizations were recognized by the Militia Act of 1792. At least one

7

mounted troop was authorized for each "division" of common militia infantry, but numerically the total cavalry was not to exceed one-eleventh of the infantry.

Mounted Kentucky militiamen figured prominently in General Anthony Wayne's victory over the Indians at Fallen Timbers in August 1794. There they helped drive the Indians from cover behind the fallen trees and into the open prairie where the Indians were at the mercy of the mounted soldiers.

War of 1812 to Civil War

By 1808 war with England was again threatening, and Congress increased the Regular Army by eight regiments-one each of light dragoons, light artillery, and riflemen and five of infantry. The dragoon regiment of eight companies constituted the only cavalry in the Regular establishment until 1812, when a second regiment was authorized. The two regiments were the cavalry force of the Regular Army during the War of 1812, and at no time were they at full authorized strength. Detachments from the regiments took part in a number of actions during 1812 and 1813-at Mississineway River in the Indiana Territory in December 1812, at the siege of Fort Meigs at the mouth of the Maumee River in Ohio the next spring, and later in Canada.

Early in 1814 Congress enacted legislation to improve the structure of the Army. By an act of 30 March the two dragoon regiments were consolidated into an 8-troop command designated the Regiment of Light Dragoons. Although the consolidated regiment seldom operated as a single unit and a year later was disbanded, detachments saw action at Lundy's Lane, Fort Erie, and Bladensburg.

Mounted militia companies throughout this period were a familiar sight in all the frontier campaigns and, when called upon, gave good account of themselves. Johnson's Kentucky Mounted Volunteers, for example, were at the Battle of the Thames River in Canada in 1813, and General Coffee's mounted Tennessee militia fought under Andrew Jackson in Alabama in 1814.

The Regiment of Dragoons was disbanded on 15 June 1815, and for seventeen years the Regular establishment again had no cavalry. Despite the arguments in Army circles for a small mounted force, Congress stood firm in its dedication to economy and a minimum standing Army.

During these years the western frontier moved well beyond the Allegheny Mountains, across the Mississippi River, up the Missouri, Arkansas, and Red Rivers, and into the plains area where the Indian was at home on horseback. By 1830 seven Army posts-scattered for 800 miles from Fort Snelling on the upper Mississippi to Fort Gibson on the Arkansas and garrisoned by detachments of Regular infantry and artillery-formed the only bulwark against Indian attack.

8

On occasion, mounted militia were called out to reinforce the Regulars. Although these volunteers were called cavalrymen, their horses usually were the same ones with which they had plowed the field and dragged logs for the new cabin. Despite poor military organization, the mounted volunteers were generally effective and constituted the only semblance of a cavalry force, but the reports of money spent to equip and pay them were later used by the advocates of cavalry to argue that a Regular force would be less expensive.

In 1813 uprisings by the Menominees at Prairie du Chien in the Northwest Territory and by Black Hawk's band at Rock Island, Illinois, provided tangible evidence of the need for an Army capable of tracking down and pursuing the Indians beyond their usual haunts. Finally, in June 1832, Congress authorized the organization of a Battalion of Mounted Rangers for defense of the frontier. Some 600 hardy frontiersmen were brought together. Experience with this battalion proved the value of a mounted force, but it also indicated the importance of having the force properly trained and disciplined. As a result, on 2 March 1833 Congress authorized a regiment of dragoons in lieu of the Battalion of Mounted Rangers. The new organization, the Regiment of United States Dragoons, was an answer to advocates of a mounted force as well as to the economy minded. It would be mounted for speed, yet trained and equipped to fight both mounted and dismounted.

The regiment, made up of a field and staff (headquarters) and 10 companies, had 34 officers and 714 men, many of whom were formerly in the Battalion of Mounted Rangers. The Ranger commander, Maj. Henry Dodge, was promoted to colonel and given command of the new regiment. Among others on the commissioned staff were a number of experienced infantrymen who were to become famous as cavalrymen. Lt. Col. Stephen Watts Kearny entered from the 3d Infantry, Lt. Jefferson Davis from the 1st Infantry, and Lt. Philip St. George Cooke from the 6th Infantry. The combination of Regulars and Rangers gave to the new regiment some officers with a thorough knowledge of military principles and others well acquainted with the type of action that all were soon to experience. None, however, were schooled in cavalry tactics. The officers of the regiment themselves practiced drilling in squads in order to be able to teach the men.

The Army then in the field consisted of 4 regiments (36 companies) of artillery, 7 regiments (70 companies) of infantry, and a regiment (10 companies) of dragoons. The total of 4,282 actually in field service manned some 50 posts scattered over the country.

While most of the Eastern Department had been cleared of Indians, three major tribes (Seminole, Creek, and Cherokee) remained in the southeast. The most troublesome were the Seminoles in Florida, and in 1835 eleven companies of artillery and infantry were sent south to subdue them. Maj. Gen. Winfield Scott, who commanded the force, reported on 29 January 1836 that no

9

mounted troops would be needed, but later wrote that horsemen would be essential to the campaign, adding that two mounted Regular companies would be worth twice that number of foot. Meanwhile, the states were called upon for mounted troops.

Congress on 23 May 1836 authorized the raising of 10,000 volunteers and a second regiment of dragoons. The volunteers could be either foot or mounted and the dragoon regiment was to be a duplicate of the regiment of dragoons already in the service. To get the organization of the new Regular regiment started, a detachment of the 1st Regiment of Dragoons, already in Florida, was reorganized as a company of the 2d Regiment of Dragoons and recruiting stations were opened at various places in the Eastern Department. In December 1836 five companies, organized in New York and South Carolina, sailed for Savannah where they left their ships, mounted the horses brought to Georgia for their use, and proceeded to Florida. The men of the remaining companies were more fortunate; they went to Jefferson Barracks, Missouri, where the regimental commander opened a school of instruction for them. In October 1837 the trained companies joined the others in Florida, traveling 1,200 miles overland in 55 days.

In the Florida war, the 2d Dragoons fought mounted less frequently than dismounted. The swamps, marshes, and rivers that separated the hummocks where the Indians had built their villages were almost impassable on foot, and the horse was often an encumbrance.

Besides the Regular cavalry, many mounted volunteers entered the Federal service during the Seminole War. In the first year, 152 companies, totaling 10,712 men, were accepted from the nearby states, and a regiment of friendly Creek Indians was organized. A South Carolina regiment, the Indian regiment, and 35 additional companies served in Florida. The others were employed in Creek and Cherokee country and on the southwestern frontier, mainly to discourage other tribes from helping the Seminoles.

At the end of the Seminole War, the Army was greatly reduced, and the dragoons were hit hard. First, the strength of the company was reduced by 10 privates; next, the number of horses in a company was cut to 40; finally, effective 4 March 1843, the 2d Dragoons were dismounted and reorganized as the Regiment of Riflemen. To turn dragoons into riflemen, only three major changes in the regimental organization actually took place: horses were eliminated, rifles replaced carbines, and the farriers and blacksmiths were discharged. Nevertheless, by this act the mounted force of the U.S. Army was again reduced to one regiment.

No sooner were the dragoons dismounted than agitation for remounting them began. It was argued that at least two mounted regiments should be stationed on the western frontier and maintained there in readiness for swift offensive action. If action were not needed, the mounted force should make a show

10

of strength at least once a year by marching into the Indian country. In 1844, as a result of these arguments and pressure from the frontier states for a greater number of mounted Regulars in that area, Congress passed legislation to remount the riflemen and to restore to the regiment its original designation. Instead of moving to the western frontier, however, the 2d Dragoons joined Brig. Gen. Zachary Taylor in Texas in 1845.

In 1846, after war with Mexico had begun, the mounted force was further increased. Legislation passed in May of that year to strengthen the entire Army included provision for seven regiments of cavalry manned by 12-month volunteers, a Regular regiment designated the Regiment of Mounted Riflemen, and an increase in the number of privates in each cavalry company.

The Regiment of Mounted Riflemen was constituted to help establish a military road to the Oregon Territory. For a number of years the opening of the road, part of it through unexplored territory, had been discussed. Money was finally appropriated and a plan developed calling for forts from the Missouri to the Columbia. That there ought to be military protection for the project was evident, and for once a mounted force appeared to be the most economical solution.

Debates in Congress on organizing this new force brought out the point that mounted troops could be used to carry the mail, as messengers, and to guard settlers going west. One member of Congress said he would vote for raising the regiment just to restore a rifle regiment to the Army. Although the United States had once been the rifle country of the world, he contended, it had fallen behind the European nations. There was not one rifle regiment in the establishment. He further stated that the unit should be mounted because, he thought, it was idle to send infantry against Indians who would be on horseback.

Headquarters of the Regiment of Mounted Riflemen was established at Jefferson Barracks in October 1846. The companies, organized at Fort McHenry, Maryland, in Columbus, Ohio, and at Jefferson Barracks, were concentrated at the barracks by the end of the year. But, instead of going to Oregon as intended, the unit joined General Scott's force in Mexico. 'In crossing the Gulf of Mexico from New Orleans to Point Isabel, Texas, the horses were washed overboard during a storm and the regiment, except for two companies mounted on captured Mexican horses, had to fight as infantry.

The regiment was armed with the Model 1841 rifle and a flintlock pistol. Through the efforts of Capt. Samuel H. Walker of the regiment and inventor Samuel Colt, the War Department purchased 1,000 Colt single-action, 6-shot revolvers for the regiment. More than 200 of the revolvers reached Vera Cruz before the end of the war, but there is no record that the unit used them in the Mexican War campaigns.

As first organized, each company of the Regiment of Mounted Riflemen had 64 privates; in 1847 the number was increased to 70, equalizing that of the

11

dragoons. At this time, too, the regiments of dragoons and riflemen were each authorized an additional major, to be promoted from among the captains.

When, because of the Mexican War, the Regular establishment was further increased by 10 new regiments in 1847, 9 were infantry, and the tenth was designated the 3d Regiment of Dragoons. Even though classed as Regular, these. 10 units were formed only for the duration and were disbanded at the close of the war.

The Mexican War afforded U.S. mounted Regular troops the first opportunity since the Revolution to engage mounted troops of a foreign organized army, and American cavalrymen took part in all of the major campaigns of the war. The 2d Dragoons were in every battle from Palo Alto to Chapultepec. The Mounted Riflemen, fighting dismounted at Chapultepec, earned from General Winfield Scott, Commanding General of the Army, the compliment that became their motto: "Brave Rifles! Veterans! You have been baptized in fire and blood and have come out steel."

During the war the regiments were broken up and the companies scattered. As in the Seminole War they often fought as infantry, but their usual missions were reconnaissance and pursuit. Several small engagements, however, were decided by traditional cavalry charges- horses at the gallop, sabers slashing. A good example was the action at Morena Bridge, near Vera Cruz, on 25 March 1847, when Col. William S. Harney placed his dismounted dragoons and infantry on the right and left of the bridge, holding mounted dragoons in reserve. After a few rounds of artillery from two cannon, the foot soldiers attacked. Once they had made some headway against the enemy, the mounted men joined in and, with their sabers swinging, drove the Mexicans across the bridge. The Mexicans reformed on the far side, but when the cavalry thundered over the bridge the enemy broke once again, and the dragoons pursued.

While Generals Scott and Taylor with most of the Regular Army and the Volunteers were winning battles in Mexico, the commands of Col. Stephen Watts Kearny and Capt. John C. Fremont were securing California and New Mexico for the United States. Colonel Kearny's force, principally mounted, consisted of his own 1st Regiment of Dragoons, the 1st Regiment of Missouri Volunteer Cavalry under Col. Alexander W. Doniphan, a mounted company from St. Louis known as the Laclede Rangers, two batteries of artillery, two small companies of volunteer infantry, and some Indian guides. Fremont had a very small command consisting principally of mounted frontiersmen.

When the war with Mexico came to an end and the usual postwar reductions of the Army began, the Regiment of Mounted Riflemen was retained as a part of the Regular establishment. All the other new regiments were mustered out, and the Volunteers were discharged and returned home.

The Regiment of Mounted Riflemen was at once ordered overland to Oregon, but many of its members took advantage of a wartime law that

12

Top

permitted Regulars to receive discharges at the conclusion of hostilities. As a result, the depleted regiment had to wait for recruits at Fort Leavenworth, Kansas. On 10 May 1849 it started its 2,000-mile trek westward, but still its organizational problems continued. After reaching the Oregon Territory the riflemen deserted in droves to go to California and join in the search for gold. In 1851 a mere skeleton of the regiment returned to Jefferson Barracks. It was again brought up to strength and then sent to the Department of Texas where, to implement the treaty of Guadalupe Hidalgo, it tried to keep the Indians of Mexico out of the United States and those of the United States in.

By 1853 the Army of 15 regiments- 4 artillery, 8 infantry, and 3 cavalrywas thinly distributed over a greatly expanded country. Artillerymen garrisoned the forts of the eastern and southern coastal areas and along the Canadian border, while infantry and cavalrymen in companies and, troops dotted the area westward from the Mississippi River. Seldom were more than two cavalry troops stationed together.

Although by that time the strength of the Army had been increased by some 3,000 to provide additional privates to companies then in the Indian country, arguments for further increases continued. The Secretary of War asked especially that more cavalry be organized for service in the Pacific Department

13

and between the Rockies and the Sierra Nevada Range. In his report of 4 December 1854 he proposed that the horse regiments be brought under one arm:

The cavalry force of our army being all required for active service of the same kind, there appears no propriety in making a permanent distinction in the designation and armament of the several regiments; it is, therefore, proposed to place all the regiments of cavalry on the same footing in these respects, and to leave it in the power of the executive to arm and equip them in such manner as may be required by the nature of the service in which they may be employed.

In 1855 the mounted force grew by two regiments. This time the new organizations were called cavalry. The 1st and 2d Cavalry were constituted on 3 March 1855 not by an act expressly dealing with Army organization, but by an addition to an appropriations bill. The two regiments were organized in the same manner as existing horse regiments but, contrary to the Secretary's recommendation, General Orders prescribing their organization made them a distinct and separate arm. Thus, the mounted force consisted of dragoons, mounted riflemen, and cavalrymen.

The 1st and 2d Cavalry were provisionally armed and equipped with available weapons. A board composed of the field officers of the two commands met in Washington in early 1855 and recommended that parts of their regiments be furnished experimental arms and equipment for trial purposes. As a result, the companies received various types of carbines, including a Springfield that was muzzle-loading, and the Merrill and the Perry, both of which loaded at the breech. Their pistols were Navy-pattern Colt revolvers and their sabers the Prussian type used by the dragoons. The dragoons remained armed with their Mexican War weapons- the Hall carbines, sabers, and horse pistols. The mounted riflemen had their Colt revolvers and percussion rifles, but they were not issued sabers. Although the rifles could be fired from horseback, the riflemen were expected to do most of their fighting dismounted.

For the Army, the years between 1848 and 1860 were marked by a succession of marches, expeditions, and campaigns against the Indians. The Army also provided protection for the settlers' wagon trains, and it explored and Surveyed the hostile Indian country. In this period, too, the slavery problem increased in intensity. When open warfare broke out in Kansas Territory between slavery and antislavery factions, nearly all the 1st Cavalry and the 2d Dragoons, together with some infantry companies, were sent there to keep the peace. They succeeded in stopping the fighting, but soon thereafter these companies and 'the rest of the Army were involved in a major conflict that lasted four long years.

Civil War

At the outbreak of the Civil War in 1861, the mounted forces in the Regular Army consisted of the five regiments mentioned, still bearing their different

14

names- dragoons, riflemen, and cavalry- and still considered three distinct arms. Besides their different firearms and the number of privates per company, which varied from time to time, the regiments had uniforms that differed principally in the color of the trim, which in 1861 was orange for the dragoons, green for the riflemen, and yellow for the cavalry. The three arms also had distinctive insignia. The dragoons and cavalrymen wore crossed sabers and the riflemen "a trumpet perpendicular." In later years the trumpet perpendicular was incorporated in the coat of arms and distinctive insignia of the 3d Cavalry- now 3d Armored Cavalry- the descendant organization of the Regiment of Mounted Riflemen.***

Small as they were, the Regular mounted forces could have been of valuable service in the early days of the Civil War if they had been readily available, but they were not. When the war began the companies of the horse regiments were widely scattered over the country; most were in the west and southwest, too distant for ready concentration. In the Battle of Bull Run in July 1861 only seven companies of Regular cavalry were included in the Union Army of about 40,000 men.

So wide a distribution of the nation's mounted forces would in itself have been sufficient cause for concern to the Army in the opening battles. Other factors, however, were equally disruptive and hard to overcome. Many officers joined the Confederacy- four of the five colonels commanding the mounted regiments resigned from the Army. More important, however, was the fact that the military leaders of the day neither valued nor understood the potential of the horse regiments. Although the cavalrymen on the western Plains had learned through experience that the continuous, long-range fire of the new breechloading rifles had destroyed the effectiveness of the saber charge against infantry, General Scott and others in Washington clung to that precept for the employment of cavalry. They did not visualize the effective employment of cavalry in broken, wooded areas. Believing that the war would be short, and noting the cost of arming, equipping, and training a mounted force, they agreed that the new improved firearms carried by the less expensive infantry rendered a more mobile force unnecessary. In January 1862 Maj. Gen. George B. McClellan urged the Secretary of War to authorize no more cavalry, to reduce the number of cavalry regiments then in the field, and to strengthen the regiments of this arm that were retained. Nevertheless, before the war ended, 272 regiments, plus 45 separate battalions, and 78 separate companies of cavalry saw service in the Union Army. Although no complete official roll of the organizations in the Confederate cavalry has been found, various estimates exist, and of

***For convenience, the word cavalry, unless otherwise indicated, will be understood to mean all three mounted forces.

15

these the most reliable shows 137 regiments, 143 separate battalions, and 101 separate companies of cavalry.

Unlike the infantry regiments, which were first mustered in to serve three months, the volunteer cavalry commands were accepted first for one year and later for three. The expense involved in equipping the cavalry soldier was still considerably greater than that for the infantryman, and it also took longer to train the cavalryman and his mount. Many organizations were severely reduced long before the term of enlistment had expired, but, since no satisfactory replacement system was ever agreed upon by all of the states and the Federal Government, the earlier regiments were retained at skeletal strength while whole new organizations entered the conflict.

While a number of mounted regiments and smaller organizations of Volunteers were mustered in for service in the Union Army, only one mounted regiment was added to the Regular establishment during the entire four years of the war. The new Regular regiment, at first designated the 3d Cavalry, differed from the other horse regiments in that from its beginning it had 12 companies instead of 10. In it, 2 companies constituted a squadron, and 2 squadrons a battalion, which was commanded by a major. A company could have any num-

16

ber of privates up to 72. In contrast, the volunteer regiments were modeled after the pattern of the old Regular cavalry.

In August 1861 all six Regular horse regiments were redesignated cavalry and renumbered as the 1st through the 6th in order, according to their respective dates of organization. All were to be armed with the saber, revolver, and carbine. Although these regiments had been known by different names, all were light cavalry. Their members were mounted on light horses, they were trained to fight mounted or dismounted, and they depended on their firearms rather than shock action with sabers. Nevertheless, the dragoons and riflemen objected to giving up their distinctive names. One captain wrote that with the renaming of the old regiments the units lost the honor attached to the old names, and the change had a demoralizing effect on the troops. The dragoons and riflemen also resisted the changes in their distinctive uniform trim; now all were expected to wear the yellow trimmings of the cavalry. Fortunately, from the dragoon and riflemen point of view, under an economy measure that permitted the use of the old uniforms until they were worn out, much orange and green trim was in evidence for a long time.

In July 1862 the number of companies in the five oldest cavalry regiments was increased from ten to twelve, thus giving them the same number of companies as the new regiment. At that time, too, the fixed squadron and battalion organization was abandoned. In actual field service, however, usually four companies, but often fewer, operated as a squadron or battalion.

In 1863 the number of privates authorized in each cavalry company was increased to one hundred, but probably no company ever succeeded in having that many men present and equipped for duty. Recruiting for Regular Army units was extremely difficult in the face of state competition. Bounties offered by Federal officers were met and exceeded by the states. So attractive were their offers that many men enlisted in one unit, deserted, and enlisted in another just to collect the bounties.

During the first two years of the war, the rule of service in the Union Army was to assign one or more regiments of cavalry to each division of infantry for such duties as the division commander might order. The regiments were then broken down into small detachments for use as orderlies and escorts for general officers, guards for division wagon trains, and pickets to protect the front of infantry lines. Although the cavalry did some effective work in the field, its discipline and morale suffered for want of a responsible chief and of a compact organization. Some cavalry brigades were organized and attached to the various corps in the summer of 1862, but it was not until 1863 that the cavalry made more than an indifferent showing. By then, as the war entered what Maj. Gen. William T. Sherman called its professional stage, the Union cavalry had gained the experience, organization, weapons, and remount service it needed, and from that time on its superiority grew steadily.

17

Soon after assuming command of the Army of the Potomac in January 1863, Maj. Gen. Joseph Hooker authorized the formation of a Cavalry Corps. The various regiments and brigades scattered through the Army were combined into divisions and placed in a separate command, a major step toward consolidation, but the idea still prevailed in. the Army that the cavalry should be used for the infantry's protection and convenience.

Another cavalry improvement in 1863 was the establishment of a Cavalry Bureau, the chief of which was charged with responsibility for organizing and equipping the cavalry forces and providing their mounts and remounts. He was also responsible for establishing depots for the reception of cavalry recruits and for the collection and initial training of cavalry horses. The Giesboro Depot in the District of Columbia became the principal remount depot for the supply of the armies in the east; St. Louis and Nashville were the depots in the Mississippi Valley.

Cavalry in the Union Army became a really effective force in 1864. Maj. Gen. Philip H. Sheridan, who assumed command of the Cavalry Corps of the Army of the Potomac in April of that year, believed that the functions of a large body of cavalry attached to an active army were not limited to guarding wagon trains or serving as advance guards or flankers for infantry columns, and upon assuming his new command he demanded the right to use the corps independently. He proved that a large force of cavalry, properly organized and led and acting as a unit, could be successful against either cavalry or infantry.

Under Sheridan's leadership, the Union cavalry played a conspicuous part in

18

numerous operations of 1864 and 1865. Some good examples are Sheridan's raid on Richmond, Maj. Gen. James H. Wilson's invasion of Alabama, and the flank attacks on Lee's army in the campaign that ended at Appomattox.

Whereas the Union leaders were slow to recognize the true value of and the need for a mounted force, the Confederate leaders seemed from the beginning to appraise cavalry and its functions at their true value. For the first two years of the war the Confederate cavalry was a strong, well-organized force, proving its efficiency on many occasions. Even before the Army of Northern Virginia was organized, separate mounted companies of the South demonstrated their effectiveness by destroying bridges along the Confederate first line of defense and gathering information about Union actions. Instead of being wasted in detail, the Confederate cavalry regiments and battalions, which had the same organization as those of the Union, were grouped into large forces capable of independent action and permitted to perform it.

The Confederate cavalry was the first to demonstrate the effectiveness of the cavalry raid, a distinct product of the American Civil War. By the end of 1862, Maj. Gen. J. E. B. Stuart and his cavalrymen had successfully accomplished two raids by which they not only gained information about the Union Army's strengths and dispositions but also obtained much needed supplies. Of equal importance, Stuart's raids greatly alarmed Federal leaders in Washington, causing them to draw off troops for the defense of that city.

The Confederate cavalry also included the partisan groups led by Brig. Gens. Turner Ashby, John H. Morgan, and Col. John Mosby. These very active commands were classified as cavalry because their men were excellent horsemen. Since the groups operated either wholly in Confederate territory or, as in the case of Morgan, in and out of friendly territory at their own dictates, they were usually able to keep themselves supplied with good mounts. They were also deserving of the name cavalry for the service they performed. The men were expert raiders who made sudden and successful attacks upon Union outposts and supply trains and disrupted lines of communications, brought in reliable information about strengths and movements, and sometimes fought delaying actions.

Unfortunately for the Confederacy, the effectiveness of its cavalry began to decline about the same time that that of the Union cavalry was on the increase. The Confederate decline was due partly to the increased efficiency of the Union horse units and partly to the fact that the South's sources of supply of both men and horses were diminishing.

Indian Wars Period

At the end of the Civil War the ranks of the Regular cavalry regiments were thin indeed, as were those of the other Regular regiments. Of the 448 companies of cavalry, infantry, and artillery authorized, 153 were not organized, and few,

19

if any, of those in being were at full strength. By July 1866 this shortage had eased since many of the members of the disbanded Volunteer outfits had by then enlisted as Regulars. By that time, however, it became apparent in Washington that the Army, even at full strength, was not large enough to perform all its duties. Consequently, on 28 July Congress authorized 4 additional cavalry regiments and enough infantry companies to reorganize the existing 19 regiments- then under two different internal organizations- into 45 regiments with 10 companies each. After this increase there were 10 regiments of cavalry, 5 of artillery, and 45 of infantry. Cavalry companies accounted for 20 percent of the total number of company-sized organizations. The Regular Army's authorized strength of approximately 57,000 officers and men was then more than double what it had been at the close of the war. The whole arrangement was remarkable because it was the first time in the nation's history that the Regular establishment had been increased substantially immediately after a war.

Recruiting for the increase began at once. Emphasis was placed upon securing veteran Volunteers before they left the service. The officers were selected from both Volunteers and Regulars; each candidate was required to have had at last two years of honorable service in the Civil War.

20

The new cavalry regiments, numbered 7th, 8th, 9th, and 10th, were organized under the same tables as the 6 already in existence. A regiment consisted of 12 companies formed into 3 squadrons of 4 companies each. Besides the commanding officer who was a colonel, the regimental staff included 7 officers, 6 enlisted men, a surgeon, and 2 assistant surgeons. Each company was authorized 4 officers, 15 noncommissioned officers, and 72 privates. A civilian veterinarian accompanied the regiment although he was not included in the table of organization.

The 9th and 10th Cavalry were composed of Negro enlisted men and white officers. Their organization differed from the others in that each had an assigned chaplain whose duties included instructing the enlisted men in fundamental school subjects. At that time and until 1901, chaplains were normally assigned to Army posts.

During the Civil War, some cavalry companies began to call themselves troops. For many years the smallest unit for administrative purposes in the cavalry was officially the company. The word troop had first officially been used in an act of 17 July 1862, which prescribed the organization of a "company or troop." The next step came when the revised regulations of 1873 omitted company. Yet for almost ten more years the U.S. Army had cavalry companies. By 1881 many units were using the newer term, and in 1883 all were directed to use it. Still later, however, it was not unusual for both terms to be used in the same regiment.

Another important provision of the act of 28 July 1866 was the authorization of a corps of Indian Scouts as an integral part of the Army. Before 1866, friendly Indians had often been employed as Army guides on the frontier, but they were not officially a part of the establishment. Under the new arrangement 1,000 Indians could be enlisted as scouts in the Indian country. They were apportioned to the various commands and continued to be used in varying numbers for about fifty years. They were last employed in the Punitive Expedition into Mexico in 1916. Most commanders found the scouts to be excellent light cavalrymen.

Among the peacetime problems the Army helped to solve, those occurring in the Great Plains and the Far West most needed the services of the mounted arm. By 1868 the bulk of the cavalry was in the west. Ninety-two companies were stationed among 59 posts within the vast area from the Canadian border to the Rio Grande and from Kansas to California. The Plains Indians who inhabited much of this area were splendid riders. They traveled and fought on horseback with a skill that gained the respect of the U.S. cavalrymen. They had mobility and speed, and since these features were characteristic of American cavalry, mounted soldiers were a more effective force than infantry in employment against them. The cavalrymen pursued marauding Indians on horseback,

21

and if the chase ended, as it usually did, in a dismounted fight, the cavalrymen were trained for that as well.

During the years immediately following the Civil War, the Army was indispensable to the opening of the Plains area. The numerous discoveries of precious metals, the availability of cheap land, and the construction of wagon roads and railroads brought more and more settlers to the new west. All needed military protection since the Indians resisted the encroachment of white society. The many posts established ahead of settlements, and abandoned when the frontier had moved beyond them, testify to the fact that the Army continuously cleared the way for civilization.

The fluid condition of the frontier caused most of the Army's work to be performed by small units. Usually a company of infantry and one of cavalry garrisoned a post, but often a single company constituted the only military protection for miles. One officer wrote that his men, few in number, kept horses saddled at all times to be ready for the danger, which was ever-present. In 1882 the troops of the 10 cavalry regiments were dispersed among 55 posts in the Indian country. The posts having the largest mounted forces were located in the Departments of Missouri and Texas. The 1st and 5th Cavalry were the most

22

widely dispersed, troops of the 1st occupying 10 stations in Washington, Oregon, Idaho, Nevada, and California, and those of the 5th 7 posts in Wyoming and Nebraska.

Such fragmentation made serious training for a foreign war impossible. Even though the country was well insulated and did not seem to be threatened by foreign powers, the high command recognized as a dangerous liability the inability to concentrate and train its units. Maj. Gen. John M. Schofield, commander of the Division of the Pacific 1882-83 and of the Division of Missouri 1883-86, described the Army as a mere police force. Beginning in the 1880's, to offset the evils of fragmentation, schools were established to give intensive training. The first of these was the School of Application for Infantry and Cavalry founded at Fort Leavenworth, Kansas, in 1881. Here, graduates of West Point put to practical application the theories they had learned at the Academy. Here, also, came student officers detailed from the field to improve the knowledge of their profession. The school troops came from the four companies of infantry and four of cavalry, plus the one light battery of artillery, which garrisoned the post. Twenty years later the school was expanded into the General Service and Staff College and opened to officers of all branches; today it is the Command and General Staff College.

In 1887 Congress appropriated $200,000 for a school at Fort Riley, Kansas, to instruct enlisted men of cavalry and light artillery, but five years went by before the Cavalry and Light Artillery School was formally established. Once it opened its doors, however, complete regimental troops and batteries trained there, as did recruits before they joined a regiment. In the years that followed, the school changed names several times, in 1907 becoming the Mounted Service School; in 1919, the Cavalry School; on 1 November 1946, the Ground General School; and in 1950, the Army General School. The school was discontinued in May 1955.

When first established, the School of Application for Infantry and Cavalry and the Cavalry and Light Artillery School were simply military posts with a training responsibility added. The department commander could order the men at the post off to duty at any time, but while not otherwise employed the garrisons formed the basis for practical instruction that enabled the officers and men who participated to study the duties of the soldier in garrison, in camp, and on the march.

The U.S. cavalry did not fight against a formally organized foe during the period of 1866-91, but doctrine and drill did evolve for use should such an enemy appear. The foundation of all the rules was the basic thought that cavalrymen must be drilled as infantry and must at all times be prepared to fight on foot. Such a provision was no more than a natural extension of Civil War experience. Instructions for mounted cavalry charges were also included.

23

A rather startling alteration occurred when the cavalry in 1873 adapted the Infantry Tactics, accepted by the infantry in 1867, as its drill manual. This system, prepared by Maj. Gen. Emory Upton, altered previous teaching because it based troop evolutions upon movements by fours. These movements were suited to drill with horses since they allowed room for the mounts to maneuver where earlier ones had not. The cavalry continued to drill by the infantry system until late in 1891, when the War Department issued separate sets of drill regulations for the cavalry, infantry, and artillery. For the cavalry, the squadron consisted of not more than four and not less than two troops, and the troop in marching was divided into two, three, or four platoons, depending upon the number of fours.

Improvement in troop distribution came about very slowly. During the late 1880's subjugation of most of the Indians and completion of many miles of railroad made possible the concentration of larger forces at fewer posts. Unfortunately, cavalry did not profit to the same degree as infantry. Indeed, until the outbreak of the War with Spain in 1898, all the cavalry units except one squadron at Fort Myer, Virginia, and one at Fort Ethan Allen, Vermont, were still stationed in the west. In that area, 92 troops remained divided among 31 posts. In many instances, as before, one troop formed the entire garrison of a post; at others there were as many as four troops; the average was two.

From 1866 until 1901 no new cavalry regiments were added to the Regular Army. There were, however, some alterations in regimental organization. In the major reduction of the Army in 1869-70, the cavalry companies lost a few noncommissioned officers, but for six years thereafter the authorized strength and organization of the companies were unchanged. In the meantime, campaigns against the Indians continued and commanders clamored for more mounted troops. At the time cavalry still constituted about one-fifth of the entire Army, roughly the same ratio as in France and Germany.

In June 1876 the Sioux wiped out Col. George A. Custer and nearly half (5 companies) of the 7th Cavalry at the Little Big Horn. Partly as a result of this catastrophe, Congress voted a permanent increase in the mounted force. The new law actually cut 5,000 from the total number of enlisted men in the Army as a whole, but added 2,500 to the cavalry units employed against the Indians. Each company so employed could have 100 enlisted men, provided the total Army strength of 25,000, then authorized, was exceeded by no more than 2,500. The maximum 100-man cavalry company continued until 1890, but few units reached the authorized strength and fewer maintained it.

By 1890 the abatement of the Indian threat brought about the first reduction in cavalry since the Civil War. Troops L and M of all regiments were disbanded and the number of privates in each of the other companies was reduced to 44, in effect a reduction of about 50 percent.

24

The next year part of the cut was restored in an experiment that attempted to integrate Indian soldiers into Regular Army units. The primary object was to give employment to a considerable number of warriors from the most dangerous tribes. Troops L of the 1st through the 8th Cavalry were reactivated with Indian enlisted personnel drawn, as nearly as possible, from the area in which each regiment was serving. For example, Troop L, 1st Cavalry, in Montana was filled in a very short time by members of the Crow tribe. That fall (1891), the regimental commander reported that the new troopers possessed all the characteristics and traits essential to good light cavalry. Nevertheless, due partly to the language barrier and partly to the general attitude that existed between the two races, the experiment failed and the last unit of this type, Troop L, 7th Cavalry, was disbanded in 1897.

Changes in the arms, uniforms, and accouterments of cavalry were few and slow. The large supply of equipment on hand in 1865, sufficient to equip the regiments for a number of years, delayed readjustments. The Spencer repeater carbines, furnished the horseman during the war, were gradually replaced after 1873 by the converted single-shot Springfield rifle and carbines of the same

25

pattern, both .45-caliber. In the category of hand guns, a few .45-caliber Colt revolvers, using metallic cartridges, were purchased in 1871-72 for testing. These revolvers became standard and remained so until replaced in 1894 by the smaller caliber .38.

Brig. Gen. George Crook, the Indian fighter and peacemaker, improved the logistics of the Indian Wars when he discarded wagon trains in favor of pack mules and thus could usually have supplies at hand. There was no waiting for the trains to catch up because the mules, each carrying about 200 pounds, were a part of the column.

Although at the beginning of the Civil War cavalry horses were scarce in the Union Army, the shortage was soon corrected and at the war's end the Army had a surplus of horses of all classes, including those for the cavalry. During the year following the close of the war, the Army sold more than 104,000 horses of all classes at public auction, and as of 30 June 1866 it still had at depots 4,645 surplus serviceable horses, of which 3,829 were for the cavalry. During the year 1866, only 150 more were purchased and they were for use in the Department of California where it was wiser to buy than to risk transporting from the east.

In 1883 the Army began to purchase horses in open market (from farmers, ranchers, and others) instead of by contract as had been the custom. This system appealed to cavalry officers and they fought for its retention when the contract method was resumed two years later. Their attitude can be understood, for in open-market procurement cavalry officers inspected and purchased horses for the cavalry, while under the contract method the Quartermaster General's Department procured and inspected all types of horses for the Army. Naturally cavalrymen, believing that only cavalrymen could select cavalry horses, objected to the change.

Cavalry officers also fought for the establishment of a remount station where all cavalry horses would be broken and trained before being shipped to the troops, and where better horses could be bred. General Crook's description of a shipment of forty horses received in his command in 1884 shows why the officers felt as they did. One of the forty bucked itself to death, another died of an obscure disease, a third gave out on the road, and sixteen were condemned by a board of officers of the regiment receiving them.

Giesboro and other depots that had made possible a ready supply of mounts during the Civil War were closed when the Cavalry Bureau was abolished on 4 October 1866. Then Carlisle, Pennsylvania, became the principal cavalry depot, but was important as a station for collecting recruits rather than for breaking and training horses. Even four years later in 1870 when the principal cavalry depot was established at St. Louis Arsenal in the midst of what was then the horse country, the depot was not important as a remount station. Thus, despite the arguments for a more effective remount service, no stations were established for this purpose until almost forty years later. In May of 1908

26

Congress authorized the establishment of a remount service, and the War Department turned over to the Quartermaster Department the Fort Reno reservation for use as a remount depot. Additional stations were opened in 1911 at Fort Keogh in Montana and at Front Royal, Virginia, and in 1916 at El Paso and Fort Sam Houston, Texas.

The cavalry fought its last Indian battle of any significance in the winter of 1890-91 when it engaged and subdued the Sioux at Wounded Knee Creek in southwestern South Dakota. Except for labor uprisings for which the Army sometimes was called out, the next few years were comparatively peaceful.

1892-1916

The years following the Indian Wars saw some improvements in the mounted arm. There were the new drill regulations, already mentioned, and the Army adopted a new shoulder arm- the Krag-Jorgensen. Manufactured as both a carbine and a rifle, the Krag-Jorgensen was a .30-caliber magazine weapon. It had a muzzle velocity of about 2,000 feet per second, and it used a cartridge containing smokeless powder. The new weapon was not in full supply by 1898 when the United States intervened in the trouble between Spain and her island possessions, but there were enough carbines to equip the Regular cavalry and one regiment of Volunteers.

Despite minor improvements, the U.S. cavalry of 1898 was not prepared for war. Enlisted cavalrymen numbered fewer than 6,000, and they were as scattered as at the opening of the Civil War, mainly through the western part of the country, though part of the 3d Cavalry was at Fort Ethan Allen, Vermont, and part of the 6th Cavalry was at Fort Myer, Virginia. Most of the troopers were garrisoning posts in Montana, Wyoming, Colorado, Kansas, and other western states. Again they were called in from great distances, some arriving on their mounts and others coming by rail.

Except for their wide dispersion, the Regular cavalry regiments of 1898 were in no worse condition than was the rest of the Army at the time. There were then only 27,000 enlisted men in the entire Army and therefore the Army had to be strengthened. For the Regular cavalry, an act of 26 April 1898 authorized the reactivation of 2 troops in each regiment- some of the reactivated troops had been inactive since 1890, and others were last filled with Indians and added to each troop a lieutenant, a sergeant, 4 corporals, and 34 privates. A troop then aggregated 104 and a regiment 1,262 officers and men.

There was no further increase in the Regular mounted arm then, but the Regular force was augmented by Volunteer organizations mustered for short terms. They were of two classes: the Volunteer Army of the United States, consisting of State Organized Militia units; and the United States Volunteers, consisting of new units recruited at large. Of the first type, three regiments and

27

nine separate troops of cavalry were mustered in from eight states. Illinois, Texas, and Ohio each furnished a regiment; Pennsylvania, three troops (Philadelphia City Troop, Governor's Troop, and Sheridan's Troop) ; Kentucky and New York, two troops each; and Nevada and Utah, one troop each. The Pennsylvanian and New York troops served in Puerto Rico and the Nevada troop in the Philippine Islands. The others did not leave the United States. Many of these units have since had continuous existence in their respective states. Now, having been converted and reorganized to be of present-day usefulness, they no longer bear the name cavalry, but each proudly remembers its origin and record in the old arm.

Acts of Congress approved on 22 and 23 April 1898 authorized the Secretary of War to organize from the nation at large Volunteer units having special qualifications. These units were to have federally appointed officers and were not to exceed a total of 3,000 men. Although Congress did not specify that the specially qualified units would be cavalry, the regiments organized under these acts were the First, Second, and Third United States Volunteer Cavalry. Of these, only one, the First United States Volunteer Cavalry, took part in the War with Spain. This regiment, better known as the "Rough Riders," had as its leaders Col. Leonard Wood and Lt. Col. Theodore Roosevelt. When organized in May 1898, the First United States Volunteer Cavalry mustered 47 officers and 994 enlisted men. It served dismounted in Cuba from 22 June until 8 August 1898 and was disbanded 15 September of the same year. The Second and Third United States Volunteer Cavalry were organized in May 1898 and disbanded in the fall of that year without having been outside the United States.

Antiquated militia laws, in effect since 1792, permitted the induction into Federal service of state organizations, poorly trained and equipped, and far below authorized strength. A look at the equipment these units brought in explains to some extent their lack of training. The firearms belonging to many of the units were worthless outmoded pieces that had to be replaced by the Federal Government. In exchange for their unserviceable arms, they received the single-shot Springfield .45-caliber rifles or carbines. These were of two models, 1896 and 1898, and the safety lock. on the 1896 model worked exactly opposite to that on the 1898 model. This difference accounted for some of the objections raised by men who received the Springfields, but their complaints were partially adjusted when an effort was made to furnish only one model within a unit. Another objection to the Springfield was based upon a comparison of it with the newer smaller-caliber Krag-Jorgensen, adopted in 1892 as a standard arm for Regulars. The Krag-Jorgensen was in short supply, while the supply of Springfields was plentiful. Fortunately the Volunteers, after training with the Springfields, were almost convinced that its single-shot action,

28

except in rapid-fire target practice, was as effective as the newer magazine-type carbine, and that the Springfield's larger bullet was more deadly.

Two large forces, one in the east and one in the west, assembled simultaneously. In preparation for service in two widely separated parts of the world, thousands of men and horses moved by way of Chickamauga, Georgia, to Tampa, Florida, for shipment to the West Indies and some 10,000 men in San Francisco awaited transportation to the Philippine Islands. Many ships were needed to move them and only a few were available. No cavalry was included in the first three shipments to the Philippines.

The Regular cavalrymen who moved east for service in the West Indies were little affected by the climate and inconveniences of the southern camps, but they were not prepared for the problems occasioned by the lack of shipping space. Because there was no room on the transports for them, about one-third of the men of each regiment and all of the horses, except those of the officers, were left behind when the expedition finally got under way. Once in combat, the troopers again demonstrated their ability to fight on foot as well as mounted.

In accordance with the act of 22 April 1898, the U.S. forces were organized into Army corps, divisions, and brigades. These were provisional commands, which ceased to exist after the war ended. Among the general officers chosen to head these larger organizations were many who had achieved prominence as cavalry leaders in the Civil and Indian Wars. Of particular interest is the fact that two former Confederate cavalrymen, for many years forbidden to serve in the United States Army, were among them- Maj. Gen. Joseph Wheeler and Maj. Gen. Fitzhugh Lee. General Wheeler commanded the cavalry division in the West Indies, and it was he who later asked for cavalrymen and their mounts in the Philippine Islands. General Lee commanded the Seventh Corps in Florida.

General Wheeler's dismounted cavalry division in Cuba consisted of about 3,000 troopers from the 1st, 3d, 6th, 9th, and 10th Cavalry and the Rough Riders. Armed with their carbines and revolvers- their sabers were left behind with the horses- and fighting as infantry, they won a victory at La Guasima on 24 June and about a week later joined the infantrymen in storming and capturing San Juan Hill and capturing the city of Santiago. In this action the Rough Riders, who in their eagerness dashed ahead of the Regulars and caught the first fire from the Spaniards' Mauser rifles, suffered heavy casualties.

There was also one mounted squadron in Cuba and one mounted troop in Puerto Rico. The squadron, composed of Troops A, C, D, and F of 2d Cavalry, mounted on local horses and commanded by Lt. Col. William A. Rafferty, formed part of an independent brigade under Brig. Gen. John C. Bates. In the dense undergrowth covering most of the country, the squadron was unable to perform some of the duties usually assigned to a mounted command, but in the Battle of El Caney its mounted detachments escorted batteries and trains to

29

the front lines, and the individual troopers acted as couriers and litter bearers. The other mounted unit, in Puerto Rico, was Troop C, New York Volunteer Cavalry.

Although no cavalry units went to the Philippine Islands in 1898, one regiment, the 4th, arrived the next year and less than two years later eight Regular regiments were employed there. In the meantime, the term of service of the Volunteers mustered for the War with Spain having expired with the signing of the Treaty of Paris, Congress acted on 2 March 1899, to increase the military force. Among other measures, it authorized three additional cavalry units and an increase in the number of enlisted men in a cavalry troop to one hundred. Two new cavalry units were organized: one the 11th United States Volunteer Cavalry, composed mainly of Americans then in the Philippine Islands; the other a squadron of Filipinos. These units were organized from volunteers recruited in accordance with the provisions of the act of 2 March 1899, which permitted enlistments of volunteers from the country at large or from localities where their services were needed, and from the Volunteer organizations whose terms of service had expired. The act also provided that volunteers having special qualifications in horsemanship and marksmanship were to be assigned to cavalry

30

for service either mounted or dismounted. Both Volunteer cavalry organizations were disbanded on 2 July 1901.

The service of the cavalry in the Philippine Islands after the capture of Aguinaldo, the leader of the Filipino independence movement, in March 1901 might well be described as daily and nightly patrols by small detachments commanded by junior officers. These little groups often encountered large bands of insurgents armed with bolos and U.S. rifles. A regimental report from the history of the 1st Cavalry is typical of the period

On December 8, 1900, detachment Troop M engaged a force of two hundred insurgents on Boot Peninsula, Lake Taal, dispersing them in a running fight of two and one-half hours duration. Private Ernest Shrey, Troop M, killed. Four insurgents killed; captured three prisoners, their arms and ammunition.

On 5 May 1901, Lieutenant Hartman with Troop K engaged about two hundred and fifty insurgents at Mount Solo, drove them from three separate positions, killing one, capturing three, also six ponies, three rifles, and three bolos.

This type of warfare afforded little space for grand strategy and tactics, but the work performed by the enterprising and courageous junior officers won them promotions and helped prepare them for higher commands in World War I. Chief among the young American officers was John J. Pershing, Captain of Cavalry.

While some U.S. troops were thus occupied in the Philippine Islands, affairs in China drew others still farther away from home. The United States made a substantial contribution to the international army that went to China at the turn of the century to protect the various embassies from attack by the Chinese Boxers. A cavalryman commanded the American contingent in the international force and the greater part of one U.S. cavalry regiment formed a part of it. The American commander was Maj. Gen. Adna R. Chaffee, Sr., an experienced Indian fighter; the cavalry regiment was the 6th, the same organization in which General Chaffee had enlisted as a private in 1861. While the regimental headquarters and 1st Squadron, 6th Cavalry, guarded American interests in Tientsin, the 3d Squadron formed a part of the force that stormed the walls of "The Forbidden City" at Peking and became the first white troops to enter the city. In China, the American cavalrymen met and fought beside cavalrymen of other nations. Among them were the First Bengal Lancers, of whom officers of the 6th furnished most complimentary reports.

On 2 February 1901, when the 2-year enlistments of the Volunteers were about to expire and the end of occupation duties in the Philippines appeared to be nowhere in sight, Congress passed an act that provided for an increase in the cavalry and infantry and completely reorganized the artillery. The increase in cavalry included 5 new regiments, numbered the 11th through the 15th. Also, it added a captain, 3 second lieutenants, a commissary sergeant, and 2 color sergeants to each regiment, old and new, and by it all regiments got a regimental

31

chaplain. The act also contained provisions for further increasing the enlisted strength of a troop from 100 to 164 at the discretion of the President. As a result, the number of enlisted men in a cavalry regiment varied. Units within the United States were reduced to the minimum, while those serving in the new island possessions were increased according to the duties being performed in each. Naturally, the greatest number were required in the Philippines, and for some years the cavalry regiments took turns serving there as well as in Hawaii, Panama, and various stations in this country, the last again mainly in the west.

From 1901 to 1916 the size of the Army varied from year to year. In 1901 Congress set the maximum strength at 100,000, and thereafter until 1916 the actual strength was regulated by annual appropriations. From 1902 to 1911 it averaged 65,616. The cavalry continued to comprise about one-fifth of the total. The Army's actual strength on 30 June 1915 was 105,993, including the Hospital Corps, the Philippine Scouts, and a regiment of Puerto Rican infantry. Of these, 15,424 were assigned to the cavalry. More than seven full regiments, or about one-half of all the cavalry, were serving on the Mexican border, two regiments were in the Philippine Islands, and one was in Hawaii.

During these years when greater interest in a more effective tactical organization of the Army was manifested, cavalry received special consideration. In 1908 the Army Chief of Staff and various department commanders recommended an increase in the infantry and artillery and a reorganization of the cavalry along "more modern" lines. For a .time, it was believed that U.S.

32

cavalry regiments should be reorganized to conform to the pattern of European regiments of the same arm. New formations suggested were actually a revival of those prescribed in Scott and Poinsett's Tactics more than seventy-five years earlier and, so far as written instructions went, had been in force during the Civil War.

European armies still clung to the idea of heavy cavalry, trained almost exclusively for the charge in mass and relying on sabers and lances. On the other hand, U.S. cavalrymen were convinced that open order formations in which the pistol, or revolver, was the principal arm produced more decisive results in mounted combat, especially when accompanied by the element of surprise and employed against fugitives or inferior troops. From 1911 until 1916 the Army conducted various experiments in cavalry reorganization and employment.

In 1911 and 1912 the 12-troop regiment was temporarily reorganized into one of six troops by consolidating two troops into one. It was supposed that this action would result in a more compact unit and bring all men within the sound of the colonel's voice. Employment of cavalry versus cavalry in mounted action was contemplated. Experimental drill regulations prescribed double rank formations, as was the European custom, and field regulations stressed more mounted action. Horsemanship, improvement of mounts, and proficiency in the use of the saber were emphasized. At the same time, it was clearly stated that cavalry's efficiency with the rifle and in fighting dismounted must not be lessened.

In answer to several Congressional proposals to reduce the cavalry from fifteen to ten regiments, the Chief of Staff in 1912 opposed any reduction, pointing out that the small amount of cavalry in the Organized Militia made it most essential that the fifteen Regular mounted regiments "be maintained and maintained at the highest degree of efficiency." At the same time, the Chief of Staff called attention to the damaging effects upon regiments that resulted from detaching troops to police the National Parks. Since the opening of Yellowstone in 1872, cavalry troops had been detached from their regiments to police the National Park lands. With the management of the reservations now under the Department of Interior, the Army suggested that Interior should employ its own rangers. When this advice was followed a few years later, the Army agreed to discharge cavalry enlisted men volunteering for service as rangers.

In October 1914 experimental cavalry service regulations (based upon the experimental drill regulations) were issued to all cavalry regiments and were given an "extensive try out" in the border service of 1915 and 1916. Reports from cavalry commanders showed that 90 percent of the commanders preferred the old statutory organization of troop, squadron, and regiment employed in single rank. They believed that a mounted unit of any size from platoon through regiment, employed in successive lines each in single rank, was just as powerful as the same number of troopers in a double rank. They also contended that this

33

system afforded much less danger of inversion and provided fresh reinforcements with proper timing, or distances, between the lines.

Consequently, new drill and service regulations issued in 1916 retained the former organization and instruction for single rank formations, but provided for movements in double rank when circumstances required. Also taken from the 1914 experimental regulations was the basic principle- leading. The new manual stated that mounted units must be habitually led by their commanders. The manual also treated in detail the training of the recruit and the new mount.

Plans for a more effective organization included 'better location of the cavalry. Upon their return from Cuba and the Philippine Islands, cavalry units had again been stationed at posts established during the Indian Wars, located far from centers of population and supply. Most of the posts were entirely too small, and many were in sections of the country where for several months in the year climatic conditions made outdoor work impracticable. As late as 1911, 49 posts in 24 states and territories were still in use, 16 of them by cavalry alone or by cavalry with infantry. Thirty-one posts had a capacity for less than a regiment, 6 could accommodate little more than a regiment, and only one could care for a brigade. The average number of companies at a post was 9, or about 650 men. Secretary of War Henry L. Stimson described the Army so distributed as "merely groups of local constabulary instead of a national organization."

In 1910-11 internal conditions in Mexico resulted in the overthrow of the government of that country and caused the United States to concentrate most of its Army strength in the southwest. Thus, for a while necessity solved the problem of a badly scattered Army. The greater part of the Regular Army moved to the border area in March 1911. While most of the cavalry patrolled the border from the mouth of the Rio Grande to San Diego, California, other units in the area were organized into one division and two independent brigades for maneuver purposes. One cavalry regiment, the 3d, formed a part of the division, and the 9th and 10th Cavalry plus a signal company made up the independent cavalry brigade. When the immediate danger subsided about five months later, the division and brigade organizations were broken up and the units comprising them returned to their former stations. One important result of the experiment was the decision to move cavalry to permanent stations in the southwest, and some outfits that had been employed there in mounted patrol duty remained in the area.

When counterrevolutions occurred in Mexico in 1913, back to the border area went a large part of the Regular Army. From then throughout World War I and many years afterward, except for the short time they were in Mexico as part of the Punitive Expedition, most U.S. cavalry regiments maintained border patrols from the Gulf of Mexico almost to California, a distance of approximately 1,700 miles. The duties of these patrols included protecting the border from incursions by individuals and small raiding parties; prevent-

34

ing violations of neutrality laws; and, in conjunction with civil authorities, barring passage of arms and ammunition from the United States into Mexico. In addition, U.S. soldiers gave medical aid to all wounded who were brought across the border. In general, the troopers performing border service lived a monotonous and unenviable life. In that desert area there was no natural protection from the burning sun of the day, and the tents in which they were housed provided little defense against the cold nights. In addition, many troopers were wounded because the Mexicans ignored repeated U.S. warnings not to fire in the direction of the border.

On the night of 8 March 1916 border events came to a head when Mexican bandits made a surprise attack on Columbus, New Mexico. As a result, U.S. soldiers crossed the border for the ostensible purpose of capturing the bandit leader, Francisco (Pancho) Villa. The Punitive Expedition into Mexico was principally a horse cavalry action, the last such in American history.

In many respects the service performed by the troopers in Mexico was comparable to that they experienced in tracking down the elusive Indians in the years following the Civil War. The hardships they endured were increased by the lack of co-operation on the part of the Mexican Government and the natives. Conflicting information as to the direction the bandits took after their forays more often than not sent the Americans on long circuitous routes, thus delaying their arrival at strategic points and giving the bandits plenty of time to escape. The rough, irregular terrain and the varied climate of Mexico added many discomforts.

It was after a forced march through the irregular terrain, during which the men were in their saddles for 17 hours out of 24, that U.S. troops fought the only battle of the expedition directly concerned with Villa. On 29 March 1916 Col. George A. Dodd and 400 men of the 7th Cavalry surprised and attacked 500 Villistas. at Guerrero.

On 9 May 1916 National Guard units from Texas, New Mexico, and Arizona were called into Federal service for patrol duty along the Mexican border. About five weeks later, on 18 June 1916, most of the remainder of the National Guard was called in. In all, these included 3 regiments, 13 separate squadrons, and 22 separate troops of cavalry. There were 108 regiments and 7 battalions of infantry and 6 regiments, 12 battalions, and 17 batteries of field artillery. Cavalry constituted a very small portion of the National Guard since the states preferred to have infantry regiments- they were considerably less expensive- but by the National Defense Act of 1916, they were required to organize more auxiliary troops and fewer infantry. The states were in the midst of a reorganization program when National Guard units were ordered into Federal service. In spite of all the confusion, the National Guardsmen moved to the border area on schedule, and eventually better legislation corrected many of the weaknesses revealed during their tour there.

35

Not since the Civil War had a sizable force been assembled for a sufficient period to train officers in the field grades. The numerous posts scattered over the vast area in which the Indian Wars were fought usually were garrisoned by a force comprised of a troop of cavalry and a company of infantry and led by company officers. Seldom were troops from several posts assembled in sufficient forces or for periods of time sufficient for officers to get practice in leading units larger than a company. In fact, during the Indian Wars many of the actions were fought by detachments commanded by lieutenants.

Even though the transportation and supply system tested during the Punitive Expedition into Mexico was found lacking in many respects, the trial gave hope of improvement over the established system. One of the innovations was the introduction of motor trucks as part of the logistics system, and many disappointments and inconveniences were occasioned by the mechanical failures of the trucks. Members of the expedition and others in Washington averse to change were not in the least surprised or disappointed that the new equipment had not yet proved that the gasoline engine would replace the horse. Yet there

36

were a farsighted few who believed in the gasoline engine and would not let their experiences discourage them in their plans for future developments.

During these years some changes were made in the composition of the cavalry regiments. In 1906 a machine gun platoon, commanded by a commissioned officer, was added to each regiment, and in 1912 a headquarters detachment and a supply detachment were added. By 1915 the machine gun platoon and the headquarters and supply detachments had become experimental troops, and the next year they became permanent. At that time, too, the experimental organization of a 6-troop regiment and the idea of reorganizing U.S. cavalry along European lines were abandoned.

Thus, the cavalry regiment of 1916 had a headquarters, a headquarters troop, a supply troop, a machine gun troop, and 12 lettered troops, the last organized into 3 squadrons of 4 troops each. All regiments had the usual complement of officers (a colonel, a lieutenant colonel, 3 majors, 15 captains, 16 first lieutenants, and 16 second lieutenants), but the number of enlisted men varied with the service required of the regiment. For example, the authorized enlisted strength of regiments serving within the continental United States was 70 men in a troop, while regiments in the Philippine Islands were permitted a total of 105 enlisted men in each lettered troop.

The National Defense Act approved on 3 June 1916 set the peace strength of the Regular Army at 220,000 officers and men and of the National Guard at 450,000. Increases to reach these strengths were to be spread over a period of five years. In units, additions to the Regular Army amounted to 10 regiments

37

of cavalry, 33 of infantry, and 15 of field artillery; 13 battalions of engineers; 93 companies of coast artillery; and a number of signal, medical, and other auxiliary troops.

The act also provided for the organization of brigades and divisions, which previously had not been permanent- that is, they had been organized during an emergency and existed only so long as the specific emergency lasted. Civil War brigades and divisions, for example, were disbanded when the war ended, and new ones created for the War with Spain were not continued after the close of that struggle.

The new plan called for 2 cavalry and 7 infantry divisions. A cavalry division consisted of a headquarters, 3 brigades (each with 3 cavalry regiments) , a horse field artillery regiment, a mounted engineer battalion, a mounted signal battalion, an aero squadron, and the necessary trains: ammunition, supply, engineer, and sanitary. The remaining 7 authorized cavalry regiments were assigned to the 7 infantry divisions, a regiment to each division, to provide a mobile force capable of performing reconnaissance, counterreconnaissance, and security missions for the division. Because of their mobility, the cavalry divisions were free for reconnaissance or other duties that took them considerable distances from the remainder of the Army. The regimental organization under the 1916 act remained unchanged, retaining its 12 lettered troops in 3 squadrons, a headquarters troop, a supply troop, and a machine gun troop. Enlisted strength of a line troop was fixed at 70 for peace and 105 for war.

As part of the 1916 plan for increase of the Army, two cavalry regiments were authorized in the first increment. Designated as the 16th and 17th, they were organized in July 1916 at Forts Sam Houston and Bliss, Texas, respectively. To enable the new organizations to become operational as soon as possible, experienced officers and men from existing cavalry regiments were transferred to the new ones, and by mid-July 1916 the 16th and 17th Cavalry were in fair shape. These were the last additions to the cavalry arm until after the declaration of war on Germany.

In the matter of arms and equipment during this period, it is important that in 1904 the new U.S. rifle Model 1903 replaced the Krag-Jorgensen as the standard arm of cavalry, as well as infantry, and remained so until the beginning of World War II. Cavalrymen readily accepted the new shoulder arm. It could be handled as well while mounted as on foot, and it had a range greater than that of the carbine.

A new side arm, the Colt automatic pistol caliber .45, was approved 29 March 1911, and by the time of the Punitive Expedition all troops in the United States were armed with it. Units going to the Philippine Islands, where there had been so much demand for an arm of this caliber, took it with them, but no special effort was made to supply those already there.

38

In 1914 the semaphore code, until that time used only by field artillery, was authorized for cavalry, infantry, and engineers. The fifty-six kits furnished for each cavalry regiment were distributed four to a troop.

World War I

Cavalry

The cavalry organization of seventeen regiments in effect when the United States entered the war against Germany was based upon the National Defense Act of 1916. In May 1917 emergency laws called for immediate increase to the full strength authorized by the National Defense Act, and organization of the remaining eight new cavalry regiments began at once. To speed up the process, certain old units in June 1917 transferred two-thirds of their men to the new regiments.

The new regiments were numbered the 18th through the 25th. But, one month after their organization was completed, all eight began training as field artillery. On 1 October 1917 Congress acted to make their conversion to field artillery legal, and on 1 November 1917 the 18th through the 25th Cavalry were redesignated as the 76th through the 83d Field Artillery. Although Congress specified that the units would reorganize as cavalry after the emergency, such action was never taken. Hence, the histories of the former 18th through 25th Cavalry are currently perpetuated in a number of artillery units.

An act of Congress on 18 May 1917 provided for twenty National Army (or temporary) cavalry regiments, which were designated 301st through 320th. Fifteen of them, the 301st through the 315th, were organized in early 1918 at various National Army camps, but in August of that year they, too, were converted to field artillery. Thirty field artillery regiments, the 44th through the 72d, and nine trench mortar batteries, the 15th through the 23d, were organized from them. None of those units served outside the United States and all were demobilized in January-February of 1919. The 316th through the 320th Cavalry were not activated during the war years.

By the time the United States entered World War I, the machine gun, together with improved artillery, barbed wire, and elaborate field fortifications, had produced a stalemate on the European Western Front. The Allies and the Germans, with their opposing armies anchored on the sea in the west and on the mountains in the east, repeatedly used waves of infantrymen and heavy artillery barrages in vain efforts to break the deadlock. Their critical need was for mobility and shock action, both traditional roles of horse cavalry, but static trench warfare and the machine gun had made use of the horse impractical.

Four regiments of U.S. cavalry- the 2d, 3d, 6th, and 15th- nevertheless formed a part of the American Expeditionary Forces, and engaged chiefly in remount duty. That they would have been used otherwise during the latter part

39

of the war, had they been available, was implied by General Pershing in 1920. He stated that, once the forces were in the open, cavalry would have been of great value on several occasions, and Allied cavalry trained in American tactics would have been most effective in the pursuit of the enemy northward toward the Meuse.

Since U.S. cavalrymen had been trained to fight dismounted as well as mounted, many of them did see action as foot soldiers. Again, as in earlier wars, many individual awards for gallantry were earned by the dismounted troopers who fought in other arms and services.

Only a very small portion of the U.S. cavalry saw any mounted service in France. In late August 1918, just before the St. Mihiel offensive, a provisional squadron was formed from Troops, B, D, F, and H of the 2d Cavalry. Fourteen officers and 404 enlisted men from those troops with convalescent horses furnished from the veterinary hospital moved to old Camp Jeanne d'Arc, near Neufchateau, for training in mounted action. Lt. Col. Oliver P. M. Hazzard commanded the squadron. Among the troop commanders was Capt. Ernest N. Harmon who, during World War II, was to command the 2d Armored Division and then the XXII Corps.

After about ten days of training, one troop of the Provisional Squadron was detached and marched to Menil-la-Tour, where it reported for courier duty with the 1st, 42d, and 89th Divisions. The remainder of the squadron reported to the 1st Division on the night of 11 September 1918, and by a few minutes past noon of the next day U.S. cavalrymen, mounted, were at Nonsard, about five miles behind the original front line of the enemy. Sent out on reconnaissance duty beyond their capabilities, the cavalrymen met the enemy in considerable force and were routed. Later, in the Meuse-Argonne action, the squadron with three troops maintained liaison between flank divisions and those on the front lines. Among the trenches, which made movement of a whole troop impracticable, small patrols, sometimes riding and sometimes walking, acted as military police and couriers. By mid-October, when withdrawn from the front, the squadron had only 150 mounted effectives, largely because of the evacuation of sick and wounded horses.

After the armistice, Headquarters, Band, and six troops of the 2d Cavalry acted as advance guard for the Army movement into Germany, and afterward were stationed along the Rhine with the American Army of Occupation.

Although few U.S. cavalry regiments went to Europe during World War I, all were well represented there by individual cavalrymen. For example, between May and September 1917, one regiment alone- the new 16th Cavalry- lost most of its original officers by promotion in the National Army; and from May 1917 until November 1918 more than a hundred enlisted members of that regiment received commissions in the National Army. Many of these men saw

40

service in France. After the armistice twenty-six of them returned and reenlisted as noncommissioned officers.

Vacancies in cavalry units created by promotion and reassignment were filled by new personnel, and the regiments were moved to the Mexican border, an area well known to the older cavalrymen. Germany's efforts to rekindle trouble between the United States and Mexico were met by the concentration of a cavalry force in the southwest. In December 1917 the 15th Cavalry Divisionthree brigades of three regiments each- was organized in Texas. There were no other cavalry divisions in the Army then, but no explanation for designating this one the 15th has been found. Like the divisions organized during previous emergencies, the life of the 15th was short. Actually, a full division organization was not completed, and it was discontinued in May 1918. The brigade headquarters lasted until July 1919 when they, too, were disbanded.

Tanks

Few recognized during World War I that the means for returning mobility and shock action to combat was already present in a device destined to revolutionize warfare on the ground and in the air. This was the internal combustion engine, which had made possible the development of the tank and eventually would lead to the mechanized forces that were to assume the old roles of horse cavalry and to loosen the grip of the machine gun on the battlefield. With increased firepower and protection, these mechanized forces would, only some twenty years later, become the armor of World War II. When the armored artillery, the armored personnel carrier, the wheeled cargo vehicle, and supporting aviation- all with adequate communications- were added to constitute the combined arms team of the modern armored division, commanders regained the capability of maneuver in most of the land areas of the world.

In the early stages of World War I, neither the Allies nor the Germans foresaw the ultimate value of the tank. In late 1914 after observing a small American-made caterpillar tractor in France, Lt. Col. Ernest D. Swinton, an English officer, recommended to the British Committee of Imperial Defence that caterpillar tractors be armored and armed for use in combat. Although his proposal was not immediately accepted by the committee, it gained strong support of one of its members, Winston S. Churchill, then First Lord of the Admiralty. The Royal Navy, largely at Churchill's urging, sponsored experiments and tests of the vehicle as a type of "land ship" during 1915, and the tank at last became a reality. In an effort to keep secret the real purpose of the early models when they were being shipped to France, the English labeled them tanks- for use as water tanks by Russia. Thus originated the name of tank for the new weapon. The naval background of the tank's development also explains such nautical tank terms as hatch, hull, bow, and ports.

41

The first test of the tank in action came when the British, on 15 September 1916, used forty-nine 30-ton Mark I's in the Somme area. The results were encouraging. More spectacular was their success over a year later, when on 20 November 1917 around 400 tanks penetrated almost six miles on a 7-mile front in an attack at Cambrai. This was the first large-scale employment of tanks in combat. Unfortunately, success was not complete because the infantry failed to exploit and secure the tanks' gains. The massed tank attack was proved feasible, nonetheless, and allayed American fears as to the tank's value; it gave renewed impetus to the United States' tank plans, and agreement was soon reached with Great Britain and France for co-ordination of all tank programs.

The British scored another victory the following year, on 8 August 1918, with 600 tanks in the Amiens salient. General Eric von Ludendorff referred to that date as the "Black Day" of the German Army, since for the first time entire German units collapsed.

The French launched their first tank attack on 16 April 1917, seven months after the initial British tank action. Of the 194 tanks used in this unsuccessful French attempt to break through the German lines, the Germans reported that 66 were destroyed. A second French tank attack, on 5 May 1917, met with considerable success, prompting a German declaration that "tanks were able, for the first time, to show their full worth without heavy losses." The most suc-

42

cessful French employment of tanks during the war was their use of 350 tanks in the Aisne-Marne offensive, beginning on 18 July 1918.

Numerous mechanical failures and the inability of the British and French to mount any sustained tank drives in the early tank actions had cast doubt on the usefulness of tanks. But tank operations and training methods in the British and French sectors had been studied carefully by United States observers, and their reports and conclusions prompted Maj. Gen. John J. Pershing, Commander in Chief, American Expeditionary Forces (AEF), to request in September 1917 that 600 heavy and 1,200 light tanks be produced in the United States.

The resulting American-produced heavy tank was the 43.5-ton Mark VIII, patterned after a British model. Armed with two 6-pounder and five .30-caliber machine guns, it was operated by an 11-man crew, had a maximum speed of 6.5 miles per hour, and a range of 50 miles. The American-built 6 ½-ton M1917 light tank was a copy of the French Renault. It had a maximum speed of 5.5 miles per hour and could travel 30 miles on its 30-gallon fuel capacity. The U.S. program was augmented in the summer of 1918 by the development of a 3-ton, 2-man tank, originated by the Ford Motor Company. This third tank to be mass-produced during 1918 was powered by two Ford Model T, 4-cylinder engines, armed with a .30-caliber machine gun, and had a maximum speed of 8 miles per hour.

43

During the fall of 1917, General Pershing approved plans for an overseas tank corps, based upon an army to be composed of 20 combat divisions. As originally planned, the tank corps was to consist of a headquarters and 5 heavy and 20 light tank battalions. Later plans increased the heavy battalions to 10. On 22 December 1917 Col. Samuel D. Rockenbach was appointed Chief of the Tank Corps, AEF. Plans developed for this organization called for a general headquarters, 3 tank centers (for training and replacement of personnel), 2 army tank headquarters, and 10 brigades. Assembly of the Tank Corps, with an authorized strength of 14,827, began on 26 January 1918, and Colonel Rockenbach was soon placed on the staff of the Commander in Chief, AEF, as an adviser on all tank matters.

In the organization of the Tank Corps, AEF, all tank units were assigned to the General Headquarters, Tank Corps. For specific combat missions, they were attached to armies or to subordinate elements and reverted to general headquarters control as directed. An army tank headquarters, designed to function with an army headquarters, consisted of a headquarters and a heavy artillery mobile ordnance repair shop.

Tables of organization and equipment (TOE) for other Tank Corps organizations were developed in 1918, although shortages of personnel and equipment for their full use prevented conclusive tests during combat. The tables provided for a light battalion of 72 light tanks and a heavy battalion of 69 heavy tanks. Both types of battalions had three companies of three platoons each and a battalion headquarters. All platoons were equipped with 5 tanks. The tank

44

brigade, with a combined total of 225 tanks, consisted of 2 light battalions, a heavy battalion, a repair and salvage company, and a brigade headquarters. Almost identical to the brigade headquarters was the headquarters of a light or a heavy tank center.

In the United States developments were also under way for a tank organization similar to that overseas. The War Department, on 18 February 1918, authorized a Tank Service, National Army, under the Chief of Engineers, and the 65th Engineers was reorganized into tank units. The Tank Service, with an authorized strength of 914 officers and 14,746 men, became a separate branch on 5 March. Col. Ira C. Welborn was named its first director and charged with organizing, arming, equipping, and training tank units. Among Welborn's duties were the supervision of all tank activities in the United States, including procurement of officers and enlisted men, and the establishment and maintenance of tank camps. The primary tank training camp was Camp Colt, Pennsylvania, which was commanded for almost seven months of 1918 by Capt., Maj., and then Lt. Col. Dwight D. Eisenhower. On 22 March 1918 the Tank Service became the Tank Corps. Neither the Tank Service nor the Tank Corps in the United States had any direct command relationship with the Tank Corps, AEF.

Units of the Tank Corps, AEF, and the Tank Corps, National Army, were organized in three separate areas during 1918-in the United States, in England, and in France. Some repetition of numerical designations resulted, and redesignations were required to eliminate the duplications. Tank units of all types were finally numbered in the 300 series.

The first tank units were organized in February 1918 as elements of the 65th Engineers. The 1st Separate Battalion, Heavy Tank Service, 65th Engineers, and the 1st and 2d Battalions, Light Tank Service, 65th Engineers, were at Camp Upton, New York, while Company D, 2d Battalion, Heavy Tank Service, 65th Engineers, was at Camp Meade, Maryland. These elements were redesignated during the war as separate battalions, numbered in the 300 series. All tank battalions were numbered 301-346, but those from 309 through 325 were not organized.

Four tank brigades were formed. Originally organized as the 1st, 2d, 3d, and 4th Provisional Tank Brigades, they were redesignated in late 1918 as the 304th through the 307th Tank Brigades, respectively.

The tank centers were also in the 300 series- being numbered from 301 through 314, although the 305th through the 308th and the 312th and 313th were never organized. The first tank centers, established overseas in February and March 1918, were initially designated as the 1st Light Tank Center and the 2d Heavy Tank Center. They, too, were redesignated into the 300 series.

There were no National Guard tank units during World War I. However, since the lineage of National Guard units is determined on a geographical basis,

45

a tank unit currently in the National Guard may descend from a World War I National Guard unit, or an even earlier organization.

Despite concentrated efforts to organize and equip tank units as soon as possible, by June 1918 only 700 men were in the AEF Tank Corps and about 5,000 in the continental U.S. organization. By late July 1918 the combat tank units overseas were: 2 heavy battalion headquarters, 3 heavy companies, 2 light battalion headquarters, and 6 light companies. In the United States there were: a heavy battalion headquarters, 12 heavy companies, a light battalion headquarters, and 24 light companies. As late as mid-August 1918 no combat tanks, either American- or foreign-made, had been assigned to any unit of either Tank Corps. By the fall of 1918, nevertheless, American tank units, using British and French tanks, were in combat. Three battalions of light tanks fought with the U.S. First Army and a battalion of heavies was with the U.S. 27th and 30th Divisions.

American tank units first entered combat on 12 September 1918 against the St. Mihiel salient with the First Army. They belonged to the 344th and 345th Light Tank Battalions, elements of the 304th Tank Brigade, commanded by Lt. Col. George S. Patton, Jr., under whom they had trained at the tank center in Bourg, France. Forty-five of the 2-man French Renault light tanks, probably the most popular type among Americans, had been issued to each battalion only about two weeks before the action. Weighing a little over 7 tons, the Renault had a maximum speed of 6 miles per hour and was armed with either a 37-mm. gun or a machine gun.

For the attack, initially, the 344th was assigned to the 1st Division and the 345th to the 42d Division, with 16 tanks from the 344th and 25 from the 345th composing the brigade reserve. Muddy conditions, caused by heavy rain the night before the offensive, resulted in a much greater consumption of gasoline than anticipated. .Although the mud, lack of gas, and mechanical failure caused many tanks to stall in the German trenches, the attack succeeded and much valuable experience was gained. In most actions tanks supported the infantry, but at times they executed normal cavalry reconnaissance missions.

In early October the tactical situation was ideal for tank employment since the Germans were short of artillery and relying heavily on their machine guns. On the other hand, the U.S. light tank battalions had been in almost continuous action during the Meuse-Argonne Campaign and numerous rear. area moves and were too weak to furnish effective support. General Pershing sent the chief of the AEF Tank Corps to Paris with instructions to "give anything in the A.E.F. for 500 tanks," but only forty-eight could be obtained locally.

The third U.S. light tank battalion, the 331st, joined the AEF in the final phase of the war. Located at Varennes, France, during early November 1918, it was also credited with participation in the Meuse-Argonne Campaign.

In the heavy tank category, the 301st Heavy Tank Battalion trained at the British Tank School at Wareham, England, from April until August 1918. It was to remain with the British Tank Corps until American tanks became available, but when the battalion arrived in France in late August 1918 and could not be supplied with American tanks, it was equipped with 47 British Mark V and Mark V Star tanks and assigned to the U.S. 27th Division. Both the Mark V and the Mark V Star had 8-man crews and a maximum speed of approximately 4 miles per hour. The Mark V Star, weighing 36 or 3 7 tons, depending upon armament, was about 5 tons heavier than the Mark V. Both were armed with either 2 6-pounder guns or an additional 2 machine guns, which were added to the Mark V's usual 4 machine guns or the Star's usual 5.

The 301st was first committed on 29 September at the Battle of Le Catelet-Bony, in support of a British offensive. For that engagement, its tanks were divided among three U.S. infantry regiments of the 27th Division and the Australian Corps Reserve. Although the attack reached its objective, it was several hours late and considered as unsuccessful. Heavy mist and haze made visibility extremely poor, but the failure was attributed mainly to lack of combined tank and infantry training before the operation and a consequent lack of co-ordination between the two as the attack progressed. Thus, the value of tank-infantry training and co-operation was recognized from the beginning of

47

the development of tactical doctrine involving the use of tanks and has continued to be given emphasis.

In the 301st's next action, on 8 October at Brancourt with the 30th Division, tank-infantry cooperation was excellent, and the tanks earned a large share of the credit for the successful advance. The 301st's tanks were again parceled out for the Battle of the Selle on 17 October, this time being split between the 27th and 30th Divisions. By 23 October the battalion could muster only a composite company of twelve tanks to support the British at Marmol Forest, but the attack reached its objective.

By the armistice of 11 November 1918, the AEF was critically short of tanks; no Americanmade tanks were completed in time for use in combat. The new weapon was a very complex item, not only requiring extensive technical training for its crew but a long lead time for production as well.

At the end of the war, the strength of the AEF Tank Corps and the Tank Corps, National Army, had reached a total of 1,090 officers and 14,780 men,

48

53 percent being in the United States and the remainder either overseas or en route.

After the war, General von Ludendorff of the German High Command praised the Allied tanks as being a principal factor in Germany's defeat. The Germans had been too late in recognizing the value of tanks to consider them in their own plans. Even if their already hard-pressed industry could have produced tanks in quantity, fuel was in very short supply. Of the total of ninety tanks fielded by the Germans during 1918, seventy-five had been captured from the Allies.

At the war's end, the main role of the tank was considered to be that of close support for the infantry. The U.S. tank units fought so briefly and were so fragmentized during the war, and the number of tanks available to them was so limited, that there was practically no opportunity to develop tactics for the large-scale employment of tanks. Nonetheless, the work of the tanks was sufficiently impressive to imbue at least a few military leaders with the idea that the use of tanks in mass was the most likely principal role of armor in the future.

Highlights of U.S. Army appraisal for the development and use of tanks, developed from combat experience, were: (1) the need for a tank with more power, fewer mechanical failures, heavier armor, longer operating range, and better ventilation; (2) the need for combined training of tanks with other combat arms, especially the infantry; (3) the need for improved means of communication and of methods for determining and maintaining directions; and (4) the need for an improved supply system, especially for gasoline and ammunition.

Between the World Wars

Tanks

Although the tank of World War I was slow, clumsy, unwieldy, difficult to control, and mechanically unreliable, its value as a combat weapon had been clearly proven. But, despite the lessons of World War I, the combat arms were most reluctant to accept a separate and independent role for armor and continued to struggle among themselves over the proper use of tanks. At the outset, thought of the tank as an auxiliary to and a part of the infantry was the predominant opinion, although a few leaders contended that an independent tank arm should be retained. After World War I came the usual American clamor for demobilization. The resulting sudden decrease in Tank Corps personnel, especially within the United States, was in sharp contrast with the rapid increase in the number of tanks on hand- and full production was just beginning. In mid-1919 the U.S. Army had 863 tanks and after deliveries on outstanding contracts were complete, 1,163. Had the war in Europe continued, there would have been five fully trained and equipped tank brigades ready for

action in the spring of 1919, one for each army corps. As it turned out, the production for World War I became the mainstay of the Army's tank pool for almost two decades.

In August 1919 the General Headquarters, Tank Corps, AEF, returned to the United States, and its chief, Brig. Gen. Samuel D. Rockenbach, became the new Chief of the Tank Corps, U.S. Army, a position he held until it was eliminated in 1920.

The Tank Corps requirements of the reorganized Regular Army after World War I were set by the General Staff in late 1918 at a general headquarters and 5 tank brigades, based upon an army of 5 corps, each with 4 divisions. As in World War I, the brigade was to consist of 3 battalions, 2 light and 1 heavy, and a repair and salvage company. Also the organization of elements within the brigade remained essentially the same as those of World War I.

Tables of organization for all units immediately following the war were of two types- one for war, the other for peace. The one for peace called for approx
