Fort Griffin, now a Texas state historic site as Fort Griffin State Historic Site, was a US Cavalry fort established 31 July 1867 by four companies of the Sixth Cavalry, U.S. Army under the command of Lt. Col. S. D. Sturgis, in the western part of North Texas, specifically northwestern Shackelford County, to give settlers protection from early Comanche and Kiowa raids. Originally called Camp Wilson after Henry Hamilton Wilson, a recently deceased lieutenant and son of Republican senator and later vice president, Henry Wilson, it was later named for Charles Griffin, a former Civil War Union general who had commanded, as de facto military governor, the Department of Texas during the early years of Reconstruction.
