Located about six miles southwest of
Merricourt, this site marks a major battle between troops of General Alfred Sully's 1863 expedition and Sioux Indians. On September 3, troops attacked a camp of Yanktonai Sioux. In the ensuing battle, 20 soldiers and nearly 200 Indian men, women, and children were killed. The site is open from May 16 through September 15, Thursday through Monday. A small museum is also on the site as well as modern facilities and a recreation area.
