Excerpts from my book, Forgotten Heroes and Villains of Sand Creek (June 11, 2010).
Medicine man, charismatic speaker, and loyal friend, Chief One Eye of the Cheyenne offered his life to make peace. Also known as Ochinee or Lone Bear, he lost an eye as a younger man while protecting the famous frontiersman William Bent from a Kiowa with a knife. Known as a medicine man among the Cheyenne, he also treated the entire Bent family over the years.
Later on, he somehow convinced Major Ned Wynkoop to travel over a hundred miles across the prairie to a large camp of Cheyenne and Arapaho, risking his life and the lives of his men to talk peace. One Eye offered himself as a sacrifice to these peace efforts.
