The "United States Regiment of Dragoons" was organized by an Act of Congress approved on 2 March 1833. It became the "First Regiment of Dragoons" when the Second Dragoons was raised in 1836. With the outbreak of the Civil War and the War Department's desire to redesignate and reorganize its mounted units, its designation was changed to "First Regiment of Cavalry" by another Act of Congress on 3 August 1861. Its Headquarters were initially established at Jefferson Barracks, near St. Louis, Missouri. In the spring of 1855, two new regiments of cavalry, the First and Second Cavalry, were authorized. One of these was named "The First Cavalry Regiment", under the command of Lt. Col. Edwin Vose Sumner, the first regular American military unit to bear that name. Sumner was previously with the First Dragoons.
The regiment was initially organized as:Headquarters: Jefferson Barracks, Missouri: 4 March 1833
Troop A: Nashville, Tennessee: 12 August 1833
Troop B: Sacketts Harbor, New York: 29 July 1833
Troop C: Louisville, Kentucky: June 1833
Troop D: Cincinnati, Ohio: 25 July 1833
Troop E: New York, New York: 29 June 1833
Troop F: Jefferson Barracks: 5 December 1833
Troop G: Jefferson Barracks: 16 January 1834
Troop H: Jefferson Barracks: 2 March 1834
The first order announcing appointments in the regiment was dated 5 March 1833, and gave the names of the colonel, lieutenant-colonel, major, four captains and four lieutenants, stating that the organization of the regiment would be perfected by the selection of officers from the "Battalion of Mounted Rangers." In June 1834, the regiment filled its complement of officers, many of whom later became noted Civil War generals:Colonel: Henry Dodge (transferred from the Battalion of Mounted Rangers)
Lieutenant Colonel: Stephen W. Kearny (transferred from the 3d Infantry Regiment)

In October 1833, the five companies first organized were sent under Colonel Dodge to winter in the vicinity of Fort Gibson, Arkansas Territory, where they remained until June 1834. Then, the regiment was sent on the Pawnee Expedition, during which, although it ended in September, a full one-fourth of the officers and men died of fever. For the winter, Headquarters with Companies A, C, D and G, were sent to Fort Leavenworth; Companies B, H and I, Lieutenant Colonel Kearny, commanding, into the Indian country on the right bank of the Mississippi River, near the mouth of the Des Moines River; and Companies E, F and K, Major Mason commanding, to Fort Gibson. Throughout the summer of 1835, all the companies of the regiment were kept in the field.
The regiment became the "First Regiment of Dragoons" when the Second Regiment of Dragoons was raised in 1836, however, the general disposition of the regiment remained unchanged. The various companies were employed in scouting among the Indians, especially along the Missouri frontier, with a portion of the regiment going to Nacogdoches, Texas, to keep white trespassers from the Indian lands, and preserving peace between whites and Indians and among the Indians themselves; also in building wagon roads and bridges. During the winter, the companies returned to their respective stations – Forts Leavenworth, Gibson and Des Moines.
Colonel Dodge resigned on 4 July 1836, and was appointed Governor of Wisconsin. He was succeeded by Lieutenant Colonel Kearny. The regiment was not heavily engaged in the Florida war, although it did take some minor casualties, including a lieutenant. In March 1837, a regimental order designated the color of the horses of each company as follows: A and K, black; B, F and H, sorrel; C, D, E and I, bay; and G, iron gray.
In October 1837, and again in March 1838, Colonel Kearny led elements of the regiment to quell Osage Indians. In April 1839, the army created Fort Wayne in Indian Territory, and Companies E, F, G and K, were stationed there for several years, with occasional forays into the field to chase hostile Indians. Kearny was promoted to brigadier general on 30 June 1846, and was succeeded by Colonel Mason.
General Kearny was placed in command of the "Army of the West (1846)," which consisted of Companies B, C, G, I and K, 1st Dragoons, an artillery battalion, some separate infantry companies, two regiments of Missouri volunteer cavalry, the famous Mormon Battalion, and the 1st Regiment of New York Volunteers, which sailed from New York City to California by ship. All in all, the Army of the West consisted of about 3,700 men, which ventured west to New Mexico, some of whom did not reach California. This command was concentrated at Bent's Fort on the Arkansas River, from which point it marched for Santa Fé on 1 August 1846. The force occupied Santa Fé without much opposition, and, after leaving part of his force there, Kearny marched into California, arriving in December.
On the morning of 6 December 1846, Kearny's 150-man command met and defeated an equal number of California lancers at San Pasqual, about 40 miles from San Diego, under Major Andres Pico. The action was severe, with the 1st Dragoons losing 3 officers and 14 men killed, principally with lance thrusts. General Kearny himself received two wounds. His force finally reached San Diego on 12 December 1846.
Kearny, with a force consisting of Company C, 1st Dragoons, (60 dismounted men) under Captain Turner, sailors and marines with a battery of artillery and California volunteers, left San Diego for Los Angeles on 29 December. Kearny's troops routed Mexicans under Governor Flores at the crossing of the Rio San Gabriel on 8 January 1847, and on the plains of La Mesa on 9 January. With the capture of Los Angeles on the following day, all Mexican resistance to the American occupation of Southern California ceased.
Kearny had left Companies G and I at Albuquerque under Capt. J. H. K. Burgwin. When Col. Sterling Price (then in command at Santa Fé) learned of the seizure and murder of the New Mexico Governor Charles Bent and five others by the Mexicans (20 January), he moved out against them with a force of about 350 dismounted men and easily defeated them, on 24 January, at Canada. Captain Burgwin defeated another Mexican force shortly thereafter and rejoined Price's column for a series of further battles.
During 1847, regimental headquarters were still at Leavenworth and Companies A and E were with Zachary Taylor in Mexico. Early in the year, Company B was reorganized at Jefferson Barracks before being sent to Santa Fe in June. On 26 June, while en route, the company was engaged by 300-400 Comanches at Grand Prairie, Arkansas, losing five men killed and six wounded. They were the first unit of the Regiment to seriously tangle with the frontier Indians. Upon reaching Santa Fe, on 6 August with the $350,000 they had been escorting, Company B was retrained as a field artillery battery to support the regiment.
Companies D, F and K saw service on Scott's line in Mexico. Company F escorted General Scott from Veracruz to Mexico City and was present at the battles near that city. From 1 November to 20 December, it was engaged on escort duty between the city and Vera Cruz. In 1848, the three companies returned to the United States and were stationed at various points on the northwestern frontier. Companies B, G, and I served with General Sterling Price in February – March 1848 in his campaign down into the State of Chihuahua and participated in the attack on Santa Cruz de Rosales.
In September 1848, the First Regiment of Dragoons rode out of Fort Kearny and returned to Fort Leavenworth in Kansas and trained their new recruits. On 11 May 1849, the regiment rode further west, and along with two companies of the 6th Infantry Regiment, guarded the treacherous Oregon Trail in the heart of Pawnee territory. In October, an engagement on the Little Blue River near Linden, Nebraska and another engagement on the Platte River resulted in numerous Pawnee fatalities, and 5 Dragoon casualties.
Brevet Brigadier General Mason, Colonel of the 1st Dragoons, died at Jefferson Barracks, on 25 July 1850, and was succeeded by Col. Thomas T. Fauntleroy, promoted from the Second Dragoons. In 1853, the newly acquired Southwest erupted in violence between the US and local Indian tribes. After a reorganization period, elements of the 1st Regiment of Dragoons set out for New Mexico on 1 July 1854. The year of 1854 was rough for the Dragoons; heavy casualties and a tenacious enemy took their toll.
Earlier in the year, on 30 March 1854, Companies F and I were stationed at Cantonment Burgwin in New Mexico, and Lieutenant J. W. Davidson, with Company I and 16 men of Company F, disobeyed his orders and boldly attacked a Jicarilla Apache camp about 16 miles south of Taos at Cieneguilla. The Indian camp was surprised and captured; while securing the camp, the troops were surprised by more Indians, who attacked the Dragoon horse-holders and took Davidson at such disadvantage that the command narrowly escaped annihilation. Fourteen men of Company I and eight of Company F were killed; Lieutenant Davidson and 14 men were wounded. Regimental headquarters was transferred to Fort Union, New Mexico Territory, in July 1854, when the rest of the regiment arrived. Throughout the following year, the companies in New Mexico were almost constantly on the move. Colonel Fauntleroy made three expeditions against the Utes and Apaches, and Companies I and K fought the Apaches. On 17 January 1855, Companies B, G, and part of K were attacked at night by a band of Apaches while camped near the Penasco River. Despite being repulsed, the Indians adopted guerrilla tactics and skirmished the next day. On the 19th, 12 troopers from B Company became separated and were ambushed by the Apache, suffering 3 killed including the Company Commander.
Meantime, out West, Companies C and E took part in the Rogue River War in Oregon Territory, in which, at the Battle of Hungry Hill, the troops were compelled to retire with a loss of 26 killed and wounded, after fighting for a day and a half.
Headquarters were moved to Fort Tejon, California, in December 1856, with the various companies scattered throughout the West. For the next five years, the regiment engaged in a variety of Indian fights, seeing action at various times against the Navajos and Apaches in the Southwest and several tribes in the Northwest. On 8 January 1859, B and K Companies fought an engagement with the Mojave in the Mohave Valley and another engagement against the Paiutes on 18–19 April 1860 near present-day Yermo, CA.
Colonel Fauntleroy resigned on 13 May 1861, and was succeeded by Col. Benjamin Lloyd Beall. On 3 August, the designation of the regiment was changed to "First Regiment of Cavalry." During November and December, the regiment, except Companies D and G, which were still stationed in New Mexico Territory, was transferred by steamship from the Pacific Coast through Panama and then to Washington, D.C., arriving by the end of January 1862. Colonel Beall retired 1 February, and was succeeded by Col. George A.H. Blake. The regiment was attached to the 2d Brigade, Cavalry Reserve, Army of the Potomac.
In the meantime, the two companies left in Confederate Arizona had abandoned and destroyed Forts Breckinridge and Buchanan and retreated to Fort Craig. Company D was engaged in a skirmish with Confederates near Fort Craig, on 19 February, and the two companies took part in the Battle of Valverde on 21 February. Company D took part in the engagements at Pigeon's Ranch, 30 March; Albuquerque, 25 April; and Peralta, 27 April.
The bulk of the 1st U.S. Cavalry, meanwhile, fought in the Peninsula Campaign in Virginia. At Williamsburg, on 4 May, a squadron under Capt. Benjamin F. "Grimes" Davis charged and repulsed Confederate cavalry, capturing a flag but losing 13 men. At Gaines' Mill, on 27 June, the regiment lost 26 more men. The regiment participated in fighting at Malvern Hill, Kelly's Ford, and during Stoneman's Raid in April and May.
At the battle of Beverly Ford in June 1863, Davis was killed while in command of the 8th New York Cavalry. At Upperville, the 1st U.S. Cavalry met the Jeff Davis Legion and the 1st and 2d North Carolina regiments in a mounted charge. The regiment lost 53 men (most to saber cuts). At Gettysburg, its loss was 16 men. Several more men were lost in a series of skirmishes during the Confederate retreat to Virginia.
In June 1863, the two companies left in New Mexico were broken up. The officers and noncommissioned officers were transferred to Carlisle Barracks, where the companies were reorganized, joining the regiment at Camp Buford, Maryland, in October 1863. After a period of rest and re-equipping near Washington D.C., the 1st Cavalry rejoined the Army of the Potomac and was engaged at Manassas Junction and at Catlett's Station, on 5 November; Culpeper, on 8 November; Stephensburg, on 26 November, and Mine River. The regiment was employed during the winter doing picket duty along the Rapidan River.
In February, the 1st U.S. Cavalry engaged in a series of fights along the Rapidan line, and then accompanied Brig. Gen. George Armstrong Custer in a raid on Charlottesville, Virginia. On General Sheridan's taking command of the Cavalry Corps, the 1st Cavalry, now commanded by Capt. N. B. Sweitzer, was attached to Merritt's Reserve or Regular Brigade, Torbert's Division, and in the preparation for the Overland Campaign, the regiment was employed in picketing the Rapidan, taking part in the battles of Todd's Tavern, on 7 May, and Spotsylvania Court House, on 8 May.
The regiment subsequently accompanied Sheridan on his daring raid around Richmond, fighting at Beaver Dam Station, on 10 May; Yellow Tavern, on 11 May: Meadow Bridge and Mechanicsville, on 12 May; Tunstall's Station, on 14 May; Hawe's Shop, on 28 May; and Old Church, on 30 May.
At the Battle of Cold Harbor, on 1 June, the regiment saw severe fighting, losing several men and officers. The 1st Cavalry then accompanied General Sheridan on his Trevilian raid, and lost 35 men in the Battle of Trevilian Station, on 11 and 12 June. The regiment was engaged in daily skirmishing during the return march to White House Landing, and was engaged there on 17 June, at the Chickahominy River on 18 June, and at the battle of Darby's Farm, on 28 June. The 1st Cavalry captured an enemy flag at the battle of Deep Bottom, on 28 July, where the Regular Brigade, fighting on foot, routed a brigade of Confederate cavalry.
On 31 July, the 1st Division marched to City Point, embarked on ships the next day, and was transported to Washington D.C. to assist in repelling the threatened attack of General Early. On 5 August, it moved towards Harpers Ferry, having been ordered to the Shenandoah Valley to rejoin Sheridan. On 10 August, the Reserve Brigade routed Confederates near Winchester. The regiment was then engaged in almost daily skirmishing, and took part in all the important valley battles except Fisher's Hill. From 16 August through 20 August, the 1st Cavalry was employed, together with the whole of the 1st Division, in the destruction of all wheat and forage, and the seizure of all horses, cattle, sheep, and hogs accessible in the valley.
The 1st Cavalry took part in the charge of the Reserve Brigade at the Battle of Opequon, on 19 September, and, in conjunction with the 2nd Cavalry, captured two stands of colors and some 200 prisoners. Its casualties were 37 killed, wounded and missing. On 28 September, in an action at Waynesboro, it suffered 18 additional casualties.
The 1st Cavalry played an important part in the Battle of Cedar Creek, 19 October. After the surprise and defeat of Horatio G. Wright in the morning, the divisions of Merritt and Custer came up as reinforcements. Two squadrons of the 1st Cavalry formed perpendicular across the Valley Pike and dismounted behind stone walls, the third squadron being held in reserve. This position was held with great difficulty, the advanced squadron being subjected to an enfilading fire.
The regiment then returned to Middletown and, during the fall and winter, engaged in numerous skirmishes and took part in Merritt's raid through the Loudoun Valley and Torbert's raid on Gordonsville. In December, the regiment was assigned to duty at the Cavalry Corps headquarters in Winchester.
On 27 February, Sheridan commenced his last expedition through the Shenandoah Valley, wanting to destroy the Virginia Central Railroad and the James River Canal, and capture Lynchburg. The 1st Cavalry took part in the Battle of Waynesboro, on 2 March, where the remnant of Early's army was captured. It was then engaged in many skirmishes during a march from Charlottesville to White House Landing, while destroying locks and the embankment of the James River Canal, railroads and Confederate supplies. It arrived at White House Landing on 17 March, taking part in a sharp engagement that day.
The 1st Cavalry was then present in all the major battles of the Cavalry Corps until the close of the war. On 30 March, it was in the engagement on White Oak Road; on 31 March, at Dinwiddie Court House; on 1 April, at Five Forks. There, the regiment charged an entrenched enemy position, carried it and seized 200 prisoners. It also fought on 2 April in the engagement near the Southside Railroad; on 6 April, at the Battle of Sayler's Creek; and on 9 April, at Appomattox Courthouse, the surrender of the Army of Northern Virginia.
The regiment then returned to Petersburg, where it remained in camp until 24 April, when it marched with the Cavalry Corps towards North Carolina for the proposed junction with Sherman. On the surrender of Joseph E. Johnston's army, the Cavalry Corps returned to Petersburg and the regiment, escorting General Sheridan, left for Washington on 8 May, arriving on 16 May and taking part in the Grand Review of the Armies.
Later that month, the regiment was ordered to Louisiana, arriving at New Orleans on 31 May and remaining there until 29 December, when it embarked for California via the Isthmus of Panama. It was stationed at the Presidio of San Francisco on 22 January, with Companies A, G and K going on 5 February to Drum Barracks, where Companies C, D and E, followed them on 17 February, Company L going to Sacramento. In June, regimental headquarters went to Fort Vancouver and the several companies were distributed through Oregon, Washington Territory, Idaho, California, Nevada and Arizona, no two being at the same station.
Owing to the vast extent of country guarded by the regiment, its service for many years following was very arduous. Scouting for Indians and escort duty of various kinds were incessant. During this period, 30 soldiers and officers serving with the regiment earned the Medal of Honor. Eighteen of these awards were for a single engagement against Apaches in the Chiricahua Mountains of Arizona, and another six were for actions in George Crook's "winter campaign" of 1872–73. The recipients were:
From 1866 to 1870, various companies from the 1st Cavalry Regiment were involved in numerous skirmishes involving Indians during the American Indian Wars throughout the west. From 1866 to 1868, they operated in Oregon, Idaho Territory Nevada and California fighting the Snake War. These skirmishes included an expedition from Fort Bidwell, CA, during 22–29 October 1866, when Company A killed 14 Indians, three women, four children, and captured an entire camp. On the nights of February 7–8, 1867, 25 men of Company B on a patrol were attacked by hostile Indians near Vicksburg Mines in Nevada. On 5 April 1868, Company F killed 32 Indians and captured two near Malheur River, Oregon.
They also fought in the Apache Wars in Arizona Territory from 1866 to 1872. On 29 January 1867, Company M encountered a band of 90 warriors at Stein's Mountain in New Mexico Territory; 60 Indians were killed and 27 captured. From 26 to 31 May 1868, eight men of Company M killed 34 Indians. At Fort McDowell in Arizona on 9–11 December 1869, 20 men from Company E killed an entire band of 11 Mojave Apaches.
On 15 December 1870, Colonel Blake was retired from active service on his own application, and Colonel Alvan C. Gillem of the 11th Infantry was transferred to the First Cavalry in his stead. Colonel Gillem died at his residence in Nashville, Tenn., 2 December 1875, and was succeeded by Colonel Cuvier Grover, promoted from the 3rd Cavalry.
The Modoc Indians were a small tribe living in northern California near Tule Lake and Lost River. Through the intercession of interested civilians, orders were issued for the Modocs removal to the Klamath Indian Reservation. They went on the reservation, but, on account of ill treatment, left it, and the War Department was then directed to enforce the orders. The Indians at once commenced hostilities and one of the most protracted and obstinate Indian wars of later years followed.
Company B left Fort Klamath, on 28 November 1872, for the purpose of arresting "Captain Jack" and the leaders of his band of Modocs, and at daylight on 29 November surprised the Indians in their camp near the Lost River. The Indians refused to surrender and an engagement followed in which eight Indians were killed and many wounded, and the camp, squaws, and property were captured. The company lost two men killed and six wounded, two of them mortally. The company then went into camp at Crowley's Ranch on Lost River opposite the Indian camp.
Company G from Fort Bidwell took station on 13 December at Land's Ranch, Tule Lake, near the Indian stronghold. The Indians attacked this camp on 21 December, and were repulsed, but not until two men and five horses had been killed. Company B now joined Company G and the two companies marched against the Indians on 16 January 1873 in conjunction with General Wheaton's column, with which Company F and a detachment of Company H were also serving at this time. The Indians attacked Companies B and G the same afternoon, but were repulsed, the companies losing three men wounded. The general engagement took place on 17 January, and lasted from 7.30 A. M. to 9.30 P. M., when the troops retired, going finally into camp at Applegate's Ranch near Clear Lake. The regiment lost two men killed and two officers, – Captain Perry and Lieutenant Kyle, – and eight men wounded, one mortally.
The Indians attacked a wagon train on 22 January, driving away the escort. However, Captain Reuben F. Bernard, 1st Cavalry, came up with reinforcements and the Indians were repulsed, losing one killed and many wounded. Company K from Fort Halleck, Nev., joined the battalion on 18 February. The battalion now consisted of Companies B, F, G and K, under Captain Biddle, who was soon succeeded by Captain Bernard. Colonel Gillem, 1st Cavalry was commanding the expedition, and Company H joined the column on 10 February.
During the night of 14 April, the companies of the 1st Cavalry moved with the rest of the command to invest the Modoc stronghold, and in the Second Battle of the Stronghold, 15–17 April, drove the Indians out of their position and into the rocks and mountains. The 1st Cavalry lost two men killed and two wounded. On 26 April, Companies B and F went to the scene of the "Thomas massacre" and brought off a number of the wounded and dead. The same companies were attacked by Indians on 10 May, at Sorass Lake, CA, but repulsed them with the loss of one warrior killed and two wounded. The command lost one killed and six wounded, two of them mortally. On 17 May, Companies B, G and K, with a battery (serving as cavalry) of the 4th Artillery, all under Major John Green, came upon a band of Modocs, which they drove five miles, killing one and capturing several squaws and children. The troops followed the trail and on 22 May, 70 Indians – men, women and children – surrendered. "Boston Charlie" was captured on 29 May, and on 31 May "Sconchin," "Scarfaced Charlie," and 27 other Indians surrendered.
Companies F and H were sent from Applegate's Ranch on 31 May to follow up on those Modocs who had eluded Green's command, finding them on 1 June, when the whole party surrendered. With the capture of "Captain Jack," the Modoc war ended, and by the end of June the companies that had been engaged in it had returned to their proper stations.
The companies left in Arizona were moved north, and by the end of October 1873, headquarters with Companies A and D were at Benicia Barracks; B at Fort Klamath; C at Camp McDermitt, Nev.; E at Fort Lapwai, Idaho Territory -, F, L and M at Fort Walla Walla, Wyoming Territory; G at Camp Bidwell, CA.; H and K at Camp Harney, Oregon.; and I at Camp Halleck, NV.
On 15 June 1877, Companies F and H, under Captain Perry, were ordered to proceed to Camas Prairie to the assistance of the settlers of Mount Idaho, I. T., who were threatened by the Nez Percé Indians under Chief Joseph. Learning that the Indians were crossing Salmon River and could be taken at a disadvantage, the march was given that direction and Chief Joseph's camp was found and taken by surprise, but the Indians quickly rallied and repulsed the troops with severe loss, Lieutenant E. W. Theller, 21st Infantry (attached), and 33 men being killed and two wounded.
All the companies of the regiment, except M at Fort Colville and A at Camp Harney watching the Piutes, were now ordered into the field against the Nez Percés. Companies E and L joined General Howard's command on 21 June; and on 1 July they surprised and attacked the camp of "Looking Glass" on the Clearwater, I. T. The village was entirely destroyed, several Indians killed and about 1,000 ponies captured. On 2 July, the same command attempted to form a junction with Company F, which was on its way from Lapwai. On 3 July, the Indians ambushed the advanced guard, consisting of Lieutenant S. M. Rains, ten men of the battalion and two civilian scouts, killing them all, and were then found to be in such force and so strongly posted that it was considered imprudent to attack them. The junction with Company F was effected, however, on 4 July, and the same afternoon the Indians attacked, the fight lasting until sunset. The battalion (E, F and L) joined General Howard at Grangerville, on 8 July. Company H had joined on 2 July, and the battalion was commanded by Captain David Perry.
On 11 July, General Howard crossed the Clearwater with his whole command and moved down that stream with Company H in advance. The Indian camp was discovered and at once attacked, the fight lasting two days and ending with the retreat of the Indians. Company B joined in time to take part in the fight on 12 July. The regiment lost three men killed and four wounded. The battalion made a reconnaissance on 18 July of the Lo-Lo trail, and the Indian scouts accompanying it were ambushed and met with considerable loss. One Nez Percé was killed.
Major Sanford's battalion, consisting of Companies C, D, I and K, joined General Howard on the Clearwater, on 28 July, and the expedition across the Lo-Lo trail began on 30 July. Companies B, C, I and K, under Major Sanford, accompanied it, and Companies D, E, G and L, with other troops under Major Green, constituted the "Reserve Column", which remained at Camas Prairie until 5 August, when it moved near to Mount Idaho, and established a permanent camp called Camp Howard. Companies F and H were stationed at Fort Lapwai.
In the Indian attack at Camas Creek on 20 August, Companies B and L were engaged, losing one man killed and one wounded. At Judith Basin, the battalion was detached from General Howard's command and directed to return, and all the companies had reached their stations by the end of November. Company K and a detachment of C, attached to General Sturgis' command, took part in the engagement with the Nez Percés at Canyon Creek, MT, on 13 September 1877.
At the outbreak of the Bannock War in May 1878, Company G was the first body of troops to reach the scene of hostilities, and Captain Bernard reported that the Indians numbered from 300 to 500. They were moving towards Steens Mountain (named after Enoch Steen, a former member of the regiment). The whole of the First Cavalry was at once ordered into the field and Colonel Grover sent to Fort Boise to take charge of operations there. Companies D, I and K, were with him. Companies F and L joined Company G on the Owyhee, 17 June, and the three companies reached Camp Harney on 21 June, where they were joined by Company A. These four companies were designated the "Left Column" by General Howard.
On the morning of 23 June, the Left Column struck the main camp of the hostiles on Silver Creek, and drove the Indians out of it and on to a cutbank, made by the creek, which had been prepared for defense. The action lasted into the night and in the morning it was found that the Indians had gone. Many Indians were killed and the camp was destroyed. The battalion lost two killed and three wounded. Company K joined the battalion on 27 June, and on 28 June the cavalry cut loose from the foot troops and pushed forward on the trail of the Indians. The fertile John Day Valley was saved in great part by this vigorous pursuit, and on 5 July General Howard overtook the command, arriving with it at Pilot Rock on 7 July. Here, it was joined by Companies E and H. The Indian camp was located and at sunrise on 8 July Captain Bernard moved his battalion to the attack.
About 300 Indians occupied the crest of the high and steep hills near Birch Creek, and were at once attacked. Captain Bernard fought his cavalry on foot without separating the men from the horses. All the companies, except A with the pack train, were deployed and used in the engagement, and the Indians were driven from three successive positions and finally four or five miles further into the mountains. Four men were wounded, one mortally, and probably 20 horses were killed. The enemy's loss is unknown; their women, children and best horses were sent off, seemingly towards the Grande Ronde, before the action began.
Lieutenant C. E. S. Wood, A. D. C., wrote: "The entire fight was closely watched by the general commanding, who desires to express his opinion that no troops ever behaved better or in a more soldierly manner than did the officers and men engaged in this encounter." The command camped for the night among the rough cañons adjacent to the battle-field.
Captain Bernard was then ordered to take his command, except Company K, to Fort Walla Walla to refit. Company K was sent to join the infantry column and with it moved to the Umatilla Agency, near which the hostiles were reported to be. Here the Indians attacked on 13 July. In the ensuing fight, Company K held the right of the line and took part in the final charge by which the Indians were driven off the field and for three miles into the hills. At the request of the Indian Agent, the command moved back to the agency that night, but two days later seven dead Indians were counted upon the battle-field.
Companies A, E, F, G, H and I, now under Lieutenant-Colonel J. W. Forsyth, 1st Cavalry, left Fort Walla Walla on 13 July – the day of the fight at Umatilla Agency – in search of the Indians, who were found to be travelling in the direction of John Day River. On 20 July, Forsyth's scouts were ambushed, which caused a halt and deployment of the command, but when the line moved forward the Indians had gone. On 22 July, the battalion reached 11 Burnt Meadows, where it was joined by Companies D and I, under Major Sanford, and on 27 July it went into camp at Malheur Agency to await supplies. The hostiles had now split up into many small parties, which were followed up and nearly all ultimately captured.
During the months of September and October, the companies were sent to their permanent stations, and the return for 30 November shows Companies A and E at Camp Harney, Oregon; B, D, F, K and M, at Fort Walla Walla, W. T.; C at Camp Bidwell, CA; G at Fort Boise, L T.; H at Fort Colville, W. T.; I at Camp Halleck, Nev., and L at Fort Klamath, Oregon.
In 1881, Companies C, G, I and M were sent to Arizona, and on 2 October, Company G, with other troops, was in action near Cedar Springs against Apaches. The hostiles fought with great boldness and desperation and the fight lasted until 9 P. M., when the Indians escaped. Company G had two men wounded and 12 horses killed. On 4 October, Companies G and I had a running fight near South Pass of the Dragoon Mountains, in which the hostiles were followed into Sonora, Mexico.
In October 1881, the "companies" began to be designated "troops" on the Regimental Return. Troop G returned to Fort McDermott on 9 November; Troop I to Camp Halleck on 27 December; Troop M to the Presidio of San Francisco on 20 January 1882; and Troop C to Fort Bidwell on 16 April.
In June 1884, the regiment was transferred to the Department of Dakota, after a tour of nearly 30 years on the Pacific coast, during the greater part of which time its stations were remote from civilization and its duties of a most arduous and thankless character. On 5 June 1885, Colonel Grover died at Atlantic City, N. J. and was succeeded by Colonel N. A. M. Dudley, promoted from the 9th Cavalry.
During this time, the headquarters and troops D, G, I, K and M, went to Fort Custer; A, C and F went to Fort Maginnis; E to Fort Ellis; H and L to Fort Assinniboine; and B to Fort Keogh.
From 1886 to 1918, Company M, 1st Cavalry was stationed at Fort Yellowstone.
Conflict with the "Crows" came in the fall of 1887, and on the morning of 4 November, Colonel Dudley left Fort Custer with Troops A, B, D, E, G and K, and Company B, 3d Infantry, with a section of Hotchkiss guns, to arrest "Sword Bearer" and the Indians who had fired into the agency buildings on the night of 30 September.
On 5 November, a demand was made upon the Indians for the surrender of these men, and they were given an hour and a half to comply with the demand. At the end of that time, the battalion of the 1st Cavalry, with Moylan's troop of the 7th Cavalry on the right, moved out in front of camp. At the same time, a 'great commotion was observed in the Indian camp, and "Sword Bearer" and another chief dashed out leading from 120 to 150 warriors equipped for battle. The Indians charged, but were repulsed and fell back into the timber alongside the river, where they had dug many rifle pits from which they now kept up a constant fire. This fire was returned, and "Sword Bearer" was seen to fall, whereupon all fighting quickly ceased. All the Indians whose surrender had been demanded and who had not been killed were at once brought in and delivered to the Department Commander, who sent them to Fort Snelling. The cavalry battalion returned to Fort Custer on 13 November.
Colonel Dudley was retired from active service on 20 August 1889, and was succeeded by Colonel J. S. Brisbin, promoted from the 9th Cavalry. On 31 December, Headquarters and Troops B, D, E, G and M, were at Fort Custer; A and L at Fort Maginnis; C, F and H at Fort Assinniboine; I at Fort Leavenworth; and K at Camp Sheridan, Wyoming.
In April 1890, the Cheyennes assumed a threatening attitude and their agent called on the commanding officer of Fort Custer for protection, who sent Major Carrol with Troops B, D and M to the Tongue River Agency, where they established Camp Crook. In September, a white boy was murdered by "Head Chief" and "Young Mule," and every attempt to arrest the murderers failed. On 11 April, the Indians sent word that they would attack the agency and on 12 April made their appearance on a hill commanding the agency buildings, where they opened fire upon them. They were soon dislodged and killed. The regiment took part in the operations against the hostile Sioux in the winter of 1890–1891, but was not brought into actual contact with them.
In December 1890, word having been received that a troop of cavalry was surrounded by hostile Indians at or near Cave Hills, Montana, Troop A made one of the most remarkable marches on record in going to its relief. It marched 186 miles, 95 of which were made in 25 hours, and 170 in 53½ hours. The report that caused such tremendous exertion proved to be without foundation.
On 22 April 1891, Colonel Brisbin was transferred to the 8th Cavalry with Colonel Abraham K. Arnold who had been the lieutenant colonel and now became the colonel of the First. In 1892, the regiment was transferred to the Department of Arizona, relieving the 10th Cavalry. Headquarters and Troops C, E, F, H and K, going to Fort Grant, Arizona.; B and I to Fort Bayard, New Mexico; D to Fort Apache, Arizona; and G to San Carlos. Troop A was at Fort Myer, Virginia, and was not moved.
In 1898, the US turned its interests to a small island in the Caribbean Sea; Cuba, which was owned by the Spanish Empire. After the USS Maine exploded in Havana Harbor, the fires of war brewed and the 1st Cavalry was moved to Chickamauga Park, Tennessee on 24 April 1898. The 1st Cavalry and the 10th Cavalry were formed into a cavalry brigade and shipped out to Cuba from Tampa, Florida. However, due to the limited space aboard the SS Leona, the troopers were forced to leave their horses behind. They fought in the Battle of Las Guasimas on 24 June, and at the Battle of San Juan Hill from 1–3 July. During the Siege of Santiago, the 1st Cavalry Regiment earned its 61st battle honor. The 1st Cavalry remained in Santiago until 8 August, and returned to the US where they were garrisoned at Fort Riley, KS, then later at Fort Robinson, NE.
On 19 June 1899, the 1st Cavalry left Ft Robinson for Fort D.A. Russell, Wyoming and began thorough training for new recruits after a brief reorganization period. When the Boxer Rebellion began in China in August 1899, the US Army garrison in the Philippines was moved to Peking to relieve the surrounded legations there, and the 1st Cavalry was sent to the Philippines on August 7, their horses following four days later. Arriving at Batangas, Luzon on 20 September, they moved to Santo Tomas just south of Manila. They busied themselves with scouting missions, escorting supplies, and patrolling the countryside and villages for guerrilla fighters.
In October 1901, a group of insurgents stole some native supplies, so 20 troopers pursued them, reclaimed the goods, and burned the village they were found in, and on 22 October, Troop B captured 5 guerrillas on Mount Makiling. From 18 November-1 December, 35 troopers from the 1st Cavalry took part in the Mount San Cristobal Expedition, which destroyed an enemy supply cache. On 15 March 1902, Troop B killed 5 insurgents on Mount Makiling, and killed 4 more on 19 March. On 16 April, the leader of these guerrillas, General Malvar, surrendered, and hostilities ceased. The 1st Cavalry Regiment was sent back home, and arrived at their new post, Fort Clark, Texas, on 1 October 1903, where they remained for three years. After the 1906 San Francisco earthquake, 1st Cavalry troopers moved there to assist, and Troop B remained in San Francisco until 9 June 1907 before returning to Texas.
The 1st Cavalry Regiment returned to the Philippines in 1908 and garrisoned Fort Stotsenburg for two years. This deployment was much quieter than their last one, and the regiment returned home on 12 February 1910. A, B, D, and K Troops were stationed at the Presidio of San Francisco and later joined the rest of their regiment at the Presidio of Monterey until 1 August 1914. Moving to Southern California, the 1st Cavalry garrisoned San Ysidro in response to growing tensions south of the border in Mexico. On 24 August 1915, the regiment moved to Calexico, California to strengthen the border and defend against raids by the bandito, Pancho Villa. They remained guarding the border while General Pershing launched the Punitive Expedition and were still there when the US entered World War I. The 1st Cavalry did not participate in the First World War, but it remained guarding the border until 19 January 1923, when they went to Fort D. A. Russell, Texas. This was their last posting as horse cavalry, and during a parade on 14 December 1932, the troopers dismounted and passed in review, saluting their horses as they left them to become a mechanized unit. Moving to Fort Knox, Kentucky, the 1st Cavalry Regiment became the first mechanized unit in the United States Army, and was redesignated the 1st Armored Regiment of the 1st Armored Division on 15 July 1940.
Once the United States entered World War II on the side of the Allies, the Army began rigorous training and reorganization to prepare for combat against the Axis. The 1st Armored Regiment, part of the 1st Armored Division, was one of the first American units to engage in combat in World War II in the North African Campaign. On 8 November 1942, the 1st Armored Regiment landed at St Leu, French Morocco and captured Tafaraoui Airfield later in the day after overrunning a battery of Vichy French guns. The next day, the regiment fought well against a counterattack by French tanks and managed to destroy 14 French R35 tanks, for the loss of 1 US tank and 1 US KIA.
After defeating the Vichy French forces in Operation Torch, the 1st Armored Regiment began its fight against the Wehrmacht in Tunisia. In one engagement against a combined German-Italian force, A Company lost six tanks but managed to draw the enemy's fire, allowing B Company to fire into the enemy's vulnerable rear, knocking out six Panzer IVs and one Panzer III before the rest retreated. Two miles to the north, Axis infantry was observed dismounting from vehicles and the remaining tanks of Companies A and B advanced on them and destroyed the enemy force.
In November 1943, the 1st Armored Regiment, as a part of the 1st Armored Division, moved to Italy and fought in the Naples-Foggia Campaign, the Allied drive to Monte Cassino. The winter months in Italy were mired in mud and stalemate. The rains and stiff German resistance on river and mountain-top defensive lines halted Allied progress. In late January 1944, the 1st Armored Regiment landed in Anzio as part of the Allied operation to outflank the German Winter Line. The armored forces broke through the German encirclement on 24 May 1944 after heavy fighting. After participating in the liberation of Rome on 5 June 1944, the 1st Armored Division was pulled off the frontline and reorganized under a new table of organization. The 1st Armored Regiment was redesignated as the 1st Tank Battalion. The division was placed back onto the line and the 1st Tank Battalion steadily advanced north and crossed the Arno on 1 September. This river crossing was followed by bloody stalemate in the North Apennines, where the rough and cold terrain hindered tank operations. Their final action in the Second World War was the Po Valley Campaign, where they fought from 21–26 April 1945. The 1st Tank Battalion was deactivated after VE Day.
When the Korean War began, the Army began re-mobilizing. 1st Battalion, 1st Armored Regiment was reactivated as the 1st Tank Battalion at Fort Hood, Texas and 2nd Battalion, 1st Armored Regiment was activated as the 100th Tank Battalion and trained until they were combined together on 15 February 1957 at Fort Polk, Louisiana to reform the 1st Cavalry Regiment.
In August 1967, the 1st Squadron, 1st Cavalry Regiment (1-1 Cavalry) was detached from the 1st Armored Division and sent to Vietnam attached to US Army Pacific. On deployment to Vietnam in 1967, the 1st Squadron 1st Cavalry Regiment consisted of three armored cavalry troops and one air cavalry troop, D Troop, which was not deployed until July 1968. 'D' Troop, 1st Squadron, 1st Cavalry Regiment was shipped to Vietnam with its aircraft to join its parent unit, the 1-1 Cavalry, which was already in Vietnam attached to the Americal Division at Chu Lai. En route, D Troop's orders were changed, temporarily attaching it to the 101st Airborne Division. The troop disembarked at Da Nang on 21 July 1968 and flew directly to Camp Eagle. The Troop then remained on combat duty in I Corps for the next four years and used the call sign Sabre. 1st Squadron, 1st Cavalry served in Chu Lai, Da Nang, Tam Kỳ, and Thach Khe. They departed Vietnam on 10 May 1972.
On 1 July 1963, the 2nd Squadron, 1st Cavalry was relieved of their duties to the 3rd Armored Division, United States Army, Europe and reassigned to the 2nd Armored Division at Fort Hood, Texas. On 8 August 1967, the unit left Fort Hood for Vietnam where they were attached to the 4th Infantry Division, headquartered in Pleiku. During their service in the Central Highlands, troopers saw action in Pleiku, Đắk Tô, Suoi Doi, Kontum, An Khe and many other nameless stretches of road and jungle. In May 1969, the squadron was transferred to Task Force South in Phan Thiet and attached to the 1st Field Force, Vietnam. Now operating in the rice paddies and rubber plantations of Vietnam, the Blackhawks further distinguished themselves in actions around Phan Thiet, Song Mao, Phan Rang and their environs. The 2-1 Cavalry departed Vietnam in October 1970, leaving Cam Ranh Bay for reassignment to the 2nd Armored Division at Fort Hood, Texas. Troop E, of 2-1 Cavalry, was raised on 1 July 1966, and served on assignment with the 11th Infantry Brigade until it 18 October 1971.
7th Squadron (Air), 1st Cavalry was a self-contained Vietnam-era air cavalry squadron, made up of 5 troops. Headquarters and Headquarters Troop (callsign Kingbird/Blackhawk), Alpha Troop (callsign Apache), Bravo Troop (callsign Dutch Master), Charlie Troop (callsign Sand Piper/Comanche) and Delta Troop (Powder Valley/Dragoon). D Troop (the squadron's armored cavalry troop) participated in successful night ambushes, escorted convoys, search and clear missions and other ground operations. Troops A, B and C were Air Cavalry units. Equipped to perform scout, insertion, interdiction and attack missions, the troops supported the ARVN 21st Division and other units throughout the Delta IV Corps area after the 9th Infantry Division returned stateside. They were first attached to the 12th Aviation Group, then from 3 June 1968, to the 164th Aviation Group. In April 1972, 7-1 Cavalry was assigned to the 194th Armored Brigade, Fort Knox, KY. In 1976, the unit was inactivated and used to form air cavalry troops in the reactivated 5th, 7th and 24th Infantry Divisions.

When Sadaam Hussein's Iraq invaded Kuwait precipitating the Gulf War, the 1st Squadron, 1st Cavalry Regiment moved to Saudi Arabia from their bases in Germany and into the line by 8 January 1991. The 1st Armored Division was in a wedge for the advance forward, and 1-1 Cavalry was at the "sharp end" of the wedge. On 24 February, the 1st Cavalry led the way across the border and covered 244 kilometers in the enemy's rear during 89 hours of sustained combat operations. 1-1 Cavalry helped destroy 4 Iraqi divisions along the way, 3 of which were members of the vaunted Republican Guard. The squadron sustained no fatalities and a limited number of wounded, and only lost two M3A2 Bradley fighting vehicles.
1-1 Cavalry was involved in Operation Joint Endeavor beginning 20 December 1995 in the Balkans. They relieved the 1st Battalion 18th Infantry Regiment of the 1st Infantry Division, and served as peacekeepers in Bosnia, with base camps in Hungary and Croatia. The 1st Squadron returned to Buedingen, Germany on 17 November 1996.
In April 2003, elements of the 1st Cavalry moved to Kuwait to begin staging for the Operation Iraqi Freedom. March, 2003, G troop, Brigade Reconnaissance Troop attached to 1st Armored Division, occupied Baghdad for the next 16 months (due to an involuntary extension imposed on them 2 weeks prior to their scheduled flight home at the 12 month mark). On 28 September 2006, the 5th Squadron, 1st Cavalry Regiment was established at Fort Wainwright, Alaska, and was assigned to the 25th Infantry Division. From September 2008 - September 2009, the 5-1 Cavalry was deployed to the eastern Diyala Governorate in Iraq.
