On this day, 25 June 1876, the Battle of the Little Bighorn began when a combined force of Lakota, Arapaho and Northern Cheyenne tribes routed Lt Col Custer’s army, killing Custer in the process. It was the biggest engagement of the Great Sioux War of 1876, during which the US military was attempting to force Native Americans from their land into reservations in order to mine newly-discovered gold in the Black Hills. Between 25 and 26 June, Native American warriors fought the 700-strong US 7th Cavalry, destroying five of its 12 companies, and killing its commanding officer, George Armstrong Custer, along with four of his relatives.
