“On November 29, 1864, Colonel John M. Chivington led approximately 700 U.S. volunteer soldiers to a village of about 500 Cheyenne and Arapaho people camped along the banks of Big Sandy Creek in southeastern Colorado. Although the Cheyenne and Arapaho people believed they were under the protection of the U.S. Army, Chivington’s troops attacked and killed about 150 people, mainly women, children, and the elderly.”
