Eventually Crazy Horse made a tough decision to lead his people, the Oglalas, to a reservation because they were starving. Game was scarce and the bison (buffalo) were nearly gone. He had no choice but to leave the Black Hills. When he arrived at Fort Robinson, he was forced to give up his weapons and horses. This made him very unhappy. One day, even though he was granted time to go on a hunt, he was lied to and, trying to get away, he was stabbed in his liver and died later that night, thus ending the Great Sioux War.
