Formed as a segregated African-American unit, the 10th Cavalry was one of the original "Buffalo Soldier" regiments in the post–Civil War Regular Army.

The regiment was trained as a combat unit but later relegated to non-combat duty and served in that capacity in World War II until its deactivation in 1944.

[11][12] Captain George Armes, Company F, 10th Cavalry, while following an active trail along the Saline River were surrounded by about 400 Cheyenne warriors.

Units of the 10th prevented the Cheyenne from fleeing to the northwest, thus allowing Custer and the 7th Cavalry to defeat them at the decisive battle near Fort Cobb, Indian Territory.

[9][10] In September and October 1868, two notable actions happened with Troops H & I under the command of Brevet Lieutenant Colonel (Captain in the Regular Army) Louis H. Carpenter.

They provided guards for workers of the Kansas and Pacific Railroad, strung miles of new telegraph lines, and to a large extent built Fort Sill.

The two groups had united forces for a retaliatory attack on regional Native American bands who had been staging raids on white settlers in the area, during what came to be called the Buffalo Hunters' War.

Due to the telegraph, news of the ongoing event and speculation reached Eastern newspapers where it was erroneously reported that the expedition had been massacred.

Encounters with the Indians usually resulted in skirmishes; however, the 10th engaged in major confrontations at Tinaja de las Palmas (a water hole south of Sierra Blanca) and at Rattlesnake Springs (north of Van Horn).

[9] In summary, from 1866 to the early 1890s, the 10th Cavalry Regiment served at a variety of posts in the Southwestern United States (Apache Wars) and Great Plains regions.

Thirteen enlisted men and six officers from the Buffalo Soldiers (four regiments including the 10th) earned the Medal of Honor during the Indian Wars.

[23] The first of these were the Battle of Las Guasimas on 24 June 1898 where Lieutenant Conley and the 10th Cavalry saved a portion of the Rough Riders from annihilation when their lead companies were ambushed and pinned down.

[23] A former brigade staff officer, then assigned to D Troop of the 10th Cavalry, First Lieutenant Jules Garesche Ord (son of General E.O.C.

Kent's men discovered that the Spanish had placed their trenches in faulty positions and were actually covered from their fire while the attackers climbed the hill.

The conflict also provided an opportunity as several senior NCOs were commissioned as officers in the Philippine Scouts, including Edward Baker.

[29] But such opportunity would be short lived as the first American Governor General, then future President, William Taft barred the four segregated "colored" regiments from continuing to serve in the Philippines.

Carter P. Johnson, rode all night with only "an orderly and a single scout," reaching the Ute camp on Little Powder late Monday.

They had an indoor riding hall, solid warm barracks, heated barns for their horses, friendly neighbors and plenty of "wholesome food."

The expedition was retaliation for Villa's invasion of the United States and attack on the village of Columbus, New Mexico, in Luna County during the Mexican Revolution.

[38][39][40] The 35th Infantry Regiment was stationed at Nogales, Arizona, on 27 August 1918, when at about 4:10 PM, a gun battle erupted unintentionally when a Mexican civilian attempted to pass through the border, back to Mexico, without being interrogated at the U.S. Customs house.

After observing the situation for a few moments, Herman ordered an attack on the Mexican and German held hilltops overlooking the border town.

[38][39] Under heavy fire, the U.S. 35th Regimental infantry soldiers and dismounted 10th Cavalry troops advanced across the Mexican–American border through the buildings and streets of Nogales, Sonora and up onto the nearby hilltops.

Troop A, 2-9th Cavalry followed and conducted route clearance, zone reconnaissance, and provided support to U.S. Army units in the interior of Panama.

The troop was located at Lane Army Airfield near An Son (14 km west of Qui Nhơn in Bình Định Province).

The exercise was intended to ensure that NATO had the ability to quickly deploy forces to West Germany in the event of a conflict with the Warsaw Pact.

On 16 June 2000, D Troop, 10th Cavalry Regiment was reactivated and assigned to the 3rd Brigade, 3rd Infantry Division (Mechanized), at Fort Benning, Georgia.

[4] The mission was assigned to the 1st Brigade Combat Team of the 4th Infantry Division, commanded by Major General Raymond Odierno and led by Colonel James Hickey of the 4th Infantry Division, with joint operations Task Force 121 – an elite and covert joint special operations team.

4th Squadron, 10th U.S. Cavalry Regiment deployed to Europe in January 2017 as part of Operation Atlantic Resolve and served in Poland, Hungary, and Germany before redeploying to Fort Carson in November 2017.

On July 29, 2022, COWBOY Troop 10th Cav reactivated on Fort Hood, Texas with COL John Meredith, commander of 1 ABCT, passing the guidon to CPT Tyler Stankye.

COWBOY Troop stood back up as part of the Army's DIVCAV pilot program in the newly designed penetration division concept.
