Camp Supply was established in November 1868 by Gen. Alfred Sully with 5 companies of 3rd Inf. It served as the supply base for Col. Custer's 7th Cav. Here, on December 2, 1868, Gen. Sheridan received Custer returning from the Battle of the Washita. The name was changed to Ft. Supply in 1889, the post was abandoned in 1893, and the buildings are now used by the State as a hospital.
