The Fetterman Fight, also known as the Fetterman Massacre or the Battle of the Hundred-in-the-Hands or the Battle of a Hundred Slain, was a battle during Red Cloud's War on December 21, 1866, between a confederation of the Lakota, Cheyenne, and Arapaho tribes and a detachment of the United States Army, based at Fort Phil Kearny, Wyoming. The U.S. military mission was intended to protect travelers on the Bozeman Trail. A group of ten warriors, including Crazy Horse, acted to lure a detachment of U.S. soldiers into an ambush. All 81 men under the command of Captain William J. Fetterman were then killed by the Native American warriors. At the time, it was the worst military disaster ever suffered by the U.S. Army on the Great Plains. The Lakota alliance emerged victorious and the remaining U.S. forces withdrew from the area. The Fetterman Fight took place on Crow Indian land that was guaranteed to them by a treaty signed with the U.S. government. The Lakota and their allies were operating without the consent of the Crow.
