The U.S.-Dakota War of 1862 & the Concentration Camp
The end came with the hanging of thirty-eight Dakota men in the town of Mankato on December 26, 1862, after 264 had been pardoned by President Abraham Lincoln and marched to a prison camp in Iowa. The remaining Dakota who surrendered – mostly the elderly, women, and their children – were forcibly marched to a winter internment camp at Fort Snelling before being exiled from Minnesota in 1863.
