In August 1862, a simmering conflict between the U.S. government and Dakota Sioux finally erupted into war. The fighting was so fierce President Lincoln had to pull troops from the Civil War and send them to Minnesota. This forgotten conflict ended with the largest mass execution in U.S. history and left a bitter legacy for both sides that lingers to this day. Historian Sue Baugh interviewed people on both sides of the conflict in Morton, MN to understand this tragic story and its relevance to today’s world.
