Sand Creek Massacre

The Sand Creek Massacre (also known as the Chivington Massacre, the Battle of Sand Creek or the Massacre of Cheyenne Indians) was an incident in the Indian Wars of the United States that occurred on November 29, 1864, when a 700-man force of Colorado Territory militia attacked and destroyed a village of friendly Cheyenne and Arapaho encamped in southeastern Colorado Territory,killing and mutilating an estimated 70–163 Indians, about two-thirds of whom were women and children. The location has been designated a National Historic Site and is administered by the National Park Service.

In the spring of 1864, while the Civil War raged in the east, Chivington launched a campaign of violence against the Cheyenne and their allies, his troops attacking any and all Indians and razing their villages. The Cheyennes, joined by neighboring Arapahos, Sioux, Comanches, and Kiowas in both Colorado and Kansas, went on the defensive warpath.Evans and Chivington reinforced their militia, raising the Third Colorado Calvary of short-term volunteers who referred to themselves as “Hundred Dazers”. After a summer of scattered small raids and clashes, white and Indian representatives met at Camp Weld outside of Denver on September 28. No treaties were signed, but the Indians believed that by reporting and camping near army posts, they would be declaring peace and accepting sanctuary.
