1864 – The Sand Creek Massacre takes place

The Sand Creek Massacre (which is also known variously as the Chivington Massacre, the Battle of Sand Creek and the Massacre of Cheyenne Indians) took place when 700 men of the Colorado Territory militia attacked and destroyed a village of Cheyenne and Arapaho encamped in southeastern Colorado Territory near Sand Creek.

133 Cheyenne and Arapaho men, women, and children at Sand Creek were killed, while 24 of the attackers were killed (and 52 more wounded). The event intensified the bloodshed of the Indian Wars, as the Arapho, and particularly the Cheyenne, sought vengeance over the next few years.
