The Battle of Wolf Mountain, also known the Battle of the Wolf Mountains, Miles's Battle on the Tongue River, and the Battle of the Butte, occurred January 8, 1877, in the Montana Territory between the United States Army and a force of Lakota Sioux and Northern Cheyenne during the Great Sioux War of 1876. The Northern Cheyenne called it the Battle of Belly Butte. It was fought about four miles southwest of modern-day Birney, along the Tongue River. In 2001, the Wolf Mountains Battlefield was listed on the National Register of Historic Places.[3] It was raised to the status of National Historic Landmark in 2008.[4]
