At Campbell's Island, located in the Mississippi River near present-day Rock Island, a day-long battle was fought in the War of 1812. On July 19, 1814, a pro-British band of Sauk Indians led by Black Hawk attacked a force of United States regulars and rangers under Lieutenant John Campbell. The Americans were defeated, with the loss of 16 American lives. Campbell's Island State Memorial consists of a North Carolina granite monument dedicated in 1908, in a mini-park overlooking the river.
