McGruff

Members of both the Cheyenne and Arapahoe tribes were attacked and killed at Sand Creek. "The Sand Creek Massacre is also called the Battle of Sand Creek, also called the Chivington Massacre. On November 29, 1864, Colorado Militia troops attacked an encampment of Cheyenne and Arapaho American Indians, about 120 miles southeast of Denver. These Indians had surrendered themselves to the U.S. Army at Fort Lyon, they were travelling to an Indian Reservation in Oklahoma, and believed themselves to be under the protection of the U.S. Government." http://www.coloradovacation.com/history/sand-creek-massacre.html Dec 27 01, 4:22 PM
