Fort Sill is located in southwestern Oklahoma in Comanche County and was established in 1869 by Maj. Gen. Philip Sheridan who led a Campaign into Indian Territory to stop hostile tribes from raiding border settlements in Texas and Kansas.

Sheridan's winter campaign involved six cavalry regiments accompanied by frontier scouts "Buffalo Bill" Cody, "Wild Bill" Hickok, Ben Clark and Jack Stilwell. Troops involved in the campaign included the 7th Cavalry, the 19th Kansas Volunteers and the 10th Cavalry and the famed "buffalo soldiers", who constructed many of the stone buildings still surrounding the old post.

The Fort Sill Museum is one of the largest in the U.S. Army. It occupies 26 buildings, of which seven are exhibit facilities open to the public. The museum contains over 32,000 historical property items, about 200,000 documents, 50,000 photos, and a library of over 12,000 books.
