Following the war, the United States government tried to forcibly remove all the Ojibwe to Minnesota, west of the Mississippi River. The Ojibwe resisted, and there were violent confrontations. In the Sandy Lake Tragedy, several hundred Ojibwe died because of the federal government's failure to deliver fall annuity payments. The government attempted to do this in the Keweenaw Peninsula in the Upper Peninsula of Michigan. Through the efforts of Chief Buffalo and the rise of popular opinion in the U.S. against Ojibwe removal, the bands east of the Mississippi were allowed to return to reservations on ceded territory. A few families were removed to Kansas as part of the Potawatomi removal.
