Buffalo Soldiers

Buffalo Soldiers were United States Army regiments composed exclusively of African American soldiers, formed during the 19th century to serve on the American frontier. On September 21, 1866, the 10th Cavalry Regiment was formed at Fort Leavenworth, Kansas. The nickname "Buffalo Soldiers" was purportedly given to the regiments by the American Indian tribes who fought against them during the American Indian Wars.

After most of the Indian Wars ended in the 1890s, the regiments continued to serve and participated in the 1898 Spanish–American War (including the Battle of San Juan Hill) in Cuba, where five more Medals of Honor were earned.
