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 atrocity 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 the Sand Creek Massacre National Historic Site and is administered by the National Park Service.
