On 21 September 1866 the 9th Cavalry Regiment was activated at Greenville, Louisiana under leadership of Colonel Edward Hatch and the 10th Cavalry Regiment was activated at Fort Leaven worth, Kansas under the leadership of Colonel Benjamin H. Grierson. In the spring and summer of 1867 the 9th and 10th Cavalry moved onto the western frontier and began more than two decades of continuous service at remote outposts and in extremely harsh conditions engaging in campaigns and skirmishes against the Plains Indians who gave the black cavalrymen the name “Buffalo Soldiers”. Colonel Grierson and the Buffalo Soldiers of the 10th Cavalry accompanied Major General Sheridan on January 8, 1869 when he staked out the site of Fort Sill at first call “Camp Wichita”. While Grierson and the 10th Cavalry were headquartered at the new garrison, the Buffalo Soldiers constructed many of the stone buildings still use surrounding the old post quadrangle at present date Fort Sill.

After the Indian Wars, troopers of the 9th and 10th Cavalry Regiments fought in Cuba participating in the Spanish-American War’s famous charge on Kettle and San Juan Hill. After Cuba the 10th Cavalry rode with General John J. Pershing over the Mexican landscape in pursuit of Pancho Villa. By 1941 the two Cavalry Regiments formed the 4th Cavalry Brigade and by 1944 the end came for horse cavalry regiments.

The 9th and 10th (Horse) Cavalry Association began at a meeting in 1966 held in Kansas City, Missouri by a group of former cavalrymen who got together to talk about their military heritage and unique military experiences. This group of veterans wanted to insure that information about their exploits and accomplishments, as black cavalrymen would not die with them. From this meeting the 9th and 10th (Horse) Cavalry Association was formed with annual reunions held at different locations throughout the Nation.
