The Indian Creek Massacre occurred on May 21, 1832 with the attack by a party of Native Americans on a group of United States settlers in LaSalle County, Illinois following a dispute about a settler-constructed dam that prevented fish from reaching a nearby Potawatomi village. The incident coincided with the Black Hawk War, but it was not a direct action of the Sauk leader Black Hawk and conflict with the United States. The removal of the dam was asked, was rejected by the settlers and between 40 and 80 Potawatomis and three Sauks attacked and killed fifteen settlers, including women and children. Two young women kidnapped by the Indians were ransomed and released unharmed about two weeks later.

The attacks at Fort Blue Mounds were two separate incidents which occurred on June 6 and 20, 1832, as part of the Black Hawk War. In the first incident, area residents attributed the killing of a miner to a band of Ho-Chunk warriors, and concluded that more Ho-Chunk planned to join Black Hawk in his war against white settlers. The second incident occurred east of the fort as a Sauk raiding party, estimated by eyewitnesses to be as large as 100 warriors, attacked two militiamen who were investigating noises heard the night before. Two members of the militia stationed at Blue Mounds were killed in the attack, and both their bodies were badly mutilated.
