In 1866, the United States Army formed the 9th and 10th Cavalry and the 24th and 25th Infantry Regiments of African American soldiers to replace the United States Colored Troops (USCT) who fought during the American Civil War. Known as the Buffalo Soldiers, these African American troops played a major role in the history of the Western frontier. After the Spanish-American War, the Buffalo Soldiers spent several months recuperating in Huntsville, Alabama. The location of their respite became known as Cavalry Hill Park. The State Black Archives exhibit includes a uniform worn by a Buffalo Soldier, a miniature replica of the Buffalo Soldiers Memorial monument in downtown Huntsville, and several framed artwork depicting the soldiers in action.
