サンドクリークの虐殺
The Sand Creek massacre (also known as the Chivington massacre, the battle of Sand Creek or the massacre of Cheyenne Indians) was a massacre of Cheyenne and Arapaho people by the U.S. Army in the American Indian Wars that occurred on November 29, 1864, when a 675-man force of the Third Colorado Cavalry under the command of U.S. Volunteers Colonel John Chivington attacked and destroyed a village of Cheyenne and Arapaho people in southeastern Colorado Territory, killing and mutilating an estimated 70 to 500 American 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. This was part of a series of events known as the Colorado War and was preceded by the Hungate massacre.
