During the American Civil War, the U.S. government formed regiments known as the United States Colored Troops, composed of black soldiers. After the war, Congress reorganized the Army and authorized the formation of two regiments of black cavalry with the designations 9th and 10th U.S. Cavalry, and four regiments of black infantry, designated the 38th, 39th, 40th and 41st Infantry Regiments (Color
ed). The 38th and 41st were reorganized as the 25th Infantry Regiment, with headquarters in Jackson Barracks in New Orleans, Louisiana, in November 1869. The 39th and 40th were reorganized as the 24th Infantry Regiment, with headquarters at Fort Clark, Texas, in April 1869. All of these units were composed of black enlisted men commanded by both white and black officers. These included the first commander of the 10th Cavalry Benjamin Grierson, the first commander of the 9th Cavalry Edward Hatch, Medal of Honor recipient Louis H. Carpenter, the unforgettable Nicholas M. Nolan, and the first black graduate of West Point, Henry O.
