Fort Washita is the former United States military post and National Historic Landmark located in Durant, Oklahoma on SH 199. Established in 1842 by General Zachary Taylor to protect citizens of the Choctaw and Chickasaw Nations from the Plains Indians, it was later abandoned by Federal forces at the beginning of the American Civil War. Confederate troops held the post until the end of the war when they burned the remaining structures. It was never reoccupied by the United States military.
