When the U.S. Department ordered all Lakota bands onto their reservations in 1876, Crazy Horse became a leader of the resistance. He chose to remain in the sacred lands of the Lakota. But constant military harassment and the decline of the buffalo population eventually forced Tashunca to surrender one year later. When he went to Fort Robinson for negotiations, a solder ran him through with a bayonet. Crazy Horse died the same night.
