Coon Creek Yellow Post #19

S. S. Volunteers Colonel John Chivington, a Methodist pastor, attacked and annihilated a village of Cheyenne and Arapaho people in southeastern Colorado Territory, killing and mutilating an estimated 70 to over 600 Native American people.

Chivington claimed 500 to 600 warriors were killed. However, most sources estimate around 150 people were killed, 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.

The massacre is considered part of a series of events known as the Colorado Wars.
