From the evening of June 25, 1876, to dusk on the 26th, General Armstrong Custer and his troops engaged in battle with the Sioux and Cheyenne at the Battle of Little Bighorn in Montana Territory.
Dull Knife (Tah-me-la-pash-me) – as he was known to the U.S. military – led the Northern Cheyennes in the battle. As was often the case from the colonial through the expansion eras, Native Americans aligned on both sides of the battle. (Although in this case, only a few Army Scouts were involved with Custer.)
