On This Day (5/5/1877): In 1877 Hunkpapa Lakota Sioux Sitting Bull refused to surrender to US troops and led his band across the border into Saskatchewan, Canada. He remained in exile for many years near Wood Mountain, refusing a pardon and the chance to return. In 1881 hunger and cold eventually forced Sitting Bull, his family, and nearly 200 other Sioux in his band to return to the United States and surrender. He is notable in American and Native American history for his role in the major victory at the Battle of the Little Bighorn against Lt. Col. George Armstrong Custer and the U.S. 7th Cavalry Regiment on June 25, 1876, where Sitting Bull’s premonition of defeating the cavalry became reality.
