Determined to resist white settlement of their country for as long as possible, the Sioux fought against the settlers and the U.S. Army for almost forty years, from 1854 to 1891. Following General Custer's defeat at Little Bighorn in 1876, the Sioux separated into smaller groups, weakening their forces significantly. The picture above, taken by army photographer Stanley J. Morrow, shows a remnant of a band of Sioux warriors who had been beaten in September 1876 at the Battle of Slim Buttes, Montana, by General George Crook, whom they had successfully repelled many times before. The Sioux prisoners are standing in front of their lodge and are flanked by American officers on either side. The flag in the picture was captured by the Sioux from General George Custer's Seventh Cavalry at the battle of Little Bighorn.
