The Republican River Expedition was a United States Army campaign from June to July 1869, aimed at expelling hostile Plains Indians, particularly the Cheyenne Dog Soldiers, from the Republican River Valley in Kansas, Nebraska, and Colorado and mapping the uncharted terrain it crossed on the way. Led by Brevet Major General Eugene A. Carr of the Fifth U.S. Cavalry, the expedition sought to safeguard American settlement in the valley following increased Indian raids in the post-Civil War period. It concluded with the Battle of Summit Springs on July 11, 1869, a decisive US Army victory that curtailed significant Indian resistance in the region.
