Amos Chapman

Amos Chapman was a civilian scout who was awarded the Medal of Honor for gallantry while in service of the United States Army during the Indian Wars. His medal was later revoked before he died as he was a civilian, but was reinstated in 1989. He was of mixed white and Native American ancestry, and married a Cheyenne woman, maintaining Native American customs throughout his life. In 2012, he was inducted into the Oklahoma Military Hall of Fame.

Chapman was born in 1837 in Michigan, to white and Native American parents. He began acting as a scout for the U.S. Army and settlers in the 1860s. In 1868 he moved to Oklahoma, and was attached to the Seventh Cavalry during General Alfred Sullys actions against the Cheyenne out of Fort Dodge. Subsequently, Camp Supply was set up and Chapman worked there as an interpreter.
