This Lakota leader played a major role in the Lakotas' long war against the United States. As a Hunkpapa Teton Sioux leader, he also served as commander of the Native American cavalry forces at the Battle of Little Bighorn. Gall was one of the most aggressive Sioux leaders in the final battles for preservation and resistance, though his story is not without controversy. Though he was Sitting Bull's chief military lieutenant during the Little Bighorn battle, he quarreled with Sitting Bull and retreated to Canada shortly thereafter. His talks with settlers did much to improve relations between the groups, but some felt he conceded too much and befriended too many white leaders. Regardless, Gall was integral to the history of the Native American plight.
