The Sand Creek massacre was an incident 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 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. Chief Black Kettle was a leader of the Southern Cheyenne after 1854, who led efforts to resist white American settlement from Kansas and Colorado territories. He and his wife were among those killed in 1868 at the Battle of Washita River, in a US Army attack on their camp by George Armstrong Custer.
Black Kettle
A prominent leader of the Cheyenne, Black Kettle demonstrated his commitment to peace by participating in several councils before the Sand Creek Massacre.
Col. John Chivington, US Black Kettle, Cheyenne The Third Colorado had about 700 men; Black Kettle could muster about 500 fighters. About 200 Cheyenne or Arapahos were killed; US losses were negligible. Scattered Indian raids had caused much ill-will between the white settlers and the Native Americans. In the autumn, Territorial (Colorado) officers had offered a vague amnesty if Indians reported to army forts. Black Kettle with many Cheyennes and a few Arapahos, believing themselves to be protected, established a winter camp about 40 miles from Fort Lyon. On November 29, Col. John Chivington, who advocated Indian extermination, arrived near the camp, having marched there from Fort Lyon. In spite of the American flag and a white flag flying over the camp, the troops attacked, killing and mutilating about 200 of the Indians, two-thirds of whom were women and children.

The Dog Soldiers or Dog Men (Cheyenne Hotametaneo'o) was one of six military societies of the Cheyenne Indians. Beginning in the late 1830s, this society evolved into a separate, militaristic band that played a dominant role in Cheyenne resistance to American expansion in Kansas, Nebraska, Colorado and Wyoming. Its members often opposed policies of peace chiefs such as Black Kettle. Today the Dog Soldiers society is making a comeback in such areas as the Northern Cheyenne Indian Reservation in Montana and among the Cheyenne and Arapaho Tribes in Oklahoma.Answer obtained from Wikipedia: search Dog Soldiers [Cheyenne warrior society].
