nov 29, 1864 - 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 American Indian Wars that occurred on November 29, 1864, when a 700-man force of Colorado Territory militia attacked and destroyed a peaceful village of Cheyenne and Arapaho in southeastern Colorado Territory, killing and mutilating an estimated 70-163 Native Americans, 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.
