Fort Supply History
Historic Fort Supply was established on November 18, 1868, as Camp of Supply for the winter campaign against the Southern Plains Indians in what is now western Oklahoma. From this post Lieutenant Colonel George A. Custer led the 7th US Cavalry south to the Washita River and destroyed the village of Cheyenne Chief Black Kettle.
The military presence in the region was felt for the next 25 years as troops from the post performed peace-keeping duties monitoring the Cheyenne and Arapaho reservation and the Cherokee Outlet. Camp Supply was the temporary seat of the Cheyenne and Arapaho Indian Agency in 1869 and early 1870.
The post served as a supply point for the Red River War of 1874–75, the final struggle in the subjugation of the tribes of the Southern Plains. In 1878 an unsuccessful attempt to stop the flight of Northern Cheyenne from the reservation precipitated the last battle between Plains Indians and US soldiers in Indian Territory.
The cavalry escorted cattle drives along the Western or Texas Trail as they made their way through the territory from Texas to Dodge City, Kansas. In the early 1880s they policed large grazing leases that cattlemen held on the tribal lands and the Cherokee Outlet. When Camp Supply became Fort Supply in December 1878, the post had become the hub of transportation and communication in a region that included southwest Kansas, the Texas Panhandle, and western Indian Territory. Troops built the roads and telegraph lines that linked the forts, reservations, and region’s settlements. They protected the stage coaches, freight haulers, and travelers as they moved along the trails.
The Land Run of 1893 opened the lands of the Cherokee Outlet to non-Indian settlement. The troops at Fort Supply policed the operation that proved to be the last major task for the soldiers. The frontier was closing and the presence of the army was no longer required. In late 1894, the post was abandoned, and the property turned over to the Department of the Interior.
The old post became the State of Oklahoma’s first state-operated mental institution with the arrival of the first patients in 1908. In 1969 the Oklahoma Historical Society assumed responsibility for the five remaining army period buildings. From 1988 to 2021 the William S. Key Correctional Center, a minimum security prison facility, occupied most of the old post and hospital grounds.
