The Sand Creek Massacre is the name of one of the most egregious massacres of American history.
In 1864, in a quiet Colorado location known in English as Sand Creek, an encampment of peaceable
Cheyenne and Arapaho Indian families under US protection were
killed and mutilated by a rogue cavalry unit despite their repeated attempts to surrender. The Sand Creek massacre was
condemned even at the time for its senselessness and extreme brutality, but the commander responsible for the
massacre, Colonel John Chivington, never faced charges for it.
