Crow King 'Kangi Yatapi'. As a prisoner of war, Crow King posed for this picture in Barry's studio at Fort Buford, D.T., in the winter of 1881. During the battle of Little Bighorn, Crow King and his band of 80 warriors attacked Custer from the south, allowing Crazy Horse and Gall to encircle the doomed 7th Cavalry. (Harbaugh, P., 1982)
