On December 21, 1866, a large band of Cheyenne and Sioux – which included Crazy Horse – under the leadership of Red Cloud attacked a wood train near the fort. Despite his unfamiliarity with frontier conditions and the methods of Indian fighting, Fetterman took command of a composite reaction force consisting of the former battalion quartermaster, Captain Frederick Brown, 2nd Lt. George Grummond, 49 enlisted troops of the 18th Infantry, 27 men of the 2nd Cavalry, and 2 civilian scouts, totaling 80 men. Ignoring his orders not to venture beyond Lodge Trail Ridge (out of sight and support distance from the fort), Fetterman pursued a small band of Sioux and was lured into an ambush. He found himself facing approximately 2,000 Indians. Within 20 minutes, Fetterman and his command had been wiped out.
