Washita Battlefield National Historic Site protects and interprets the site of the Southern Cheyenne village of Peace Chief Black Kettle that was attacked by the 7th U.S. Cavalry under Lt. Col. George A. Custer just before dawn on November 27, 1868. The controversial strike was hailed at the time by the military and many civilians as a significant victory aimed at reducing Native American raids on frontier settlements. Washita remains controversial because many Cheyenne and whites labeled Custer's attack a massacre. Black Kettle is still honored as a prominent leader who never ceased striving for peace even though it cost him his life. Leashed pets are permitted in the park, but are not allowed in the buildings. Leashes must be no longer than six feet.
