A group of Native police were sent to his cabin on the Grand River, and at dawn on December 15, 1890, Sitting Bull, along with Crowfoot and Sitting Bull’s adopted brother Jumping Bull, was shot to death. A handful of Sitting Bull’s supporters fled to the Pine Ridge Agency to the south, where Custer’s old regiment, the Seventh Cavalry, had been called in to put a stop to the Ghost Dance craze. The massacre that unfolded on December 29 at a creek called Wounded Knee was seen by at least some of the officers of the Seventh Cavalry as overdue revenge for their defeat at the Little Bighorn.
