Ochinee, a sub-chief,[1] helped negotiate a treaty between the government, Cheyenne, and Arapaho to safely camp along Sand Creek during the winter of 1864–1865.
[2] Ochinee went to Fort Lyon on September 4, 1864 with his wife to deliver a letter to Major Ned Wynkoop from Black Kettle and other chiefs.
[3] Ochinee, his wife Minimic, and a man that had accompanied them, were put under guard and taken on a four-day ride with 127 soldiers and taken to an encampment of Arapaho and Cheyenne people on the Smoky Hill River.
[6] On November 29, 1864, the Cheyenne encampment at the Sand Creek was attacked by 600 soldiers of the Colorado Volunteer Cavalry and Ochinee and 160 other people, most of whom were children and women, were killed.
[11] Ochinee's wife, Amache, and her two oldest daughters each received reparations by the United States government in the form of 640 acres of land along the Arkansas River, which she used to expand her family's cattle ranch.
