The Battle of Rock Island Rapids, also called the Battle of Campbell Island, was an American defeat during the War of 1812 at the hands of the British allied Sauk, Fox, and Kickapoo. In July 1814, a military expedition was mounted to supply the U.S garrison at Prairie du Chien after calls for help. The U.S expedition was ambushed on July 19. In the aftermath another expedition was sent to re-capture Prairie after it fell to the British. This expedition was too ambushed in the Battle of Credit Island and forced to retreat southwards.
