The Ho-Chunks and Potawatomis who took part in the war were sometimes motivated by grievances not directly related to Black Hawk's objectives. One such incident was the Indian Creek massacre. In the spring of 1832, Potawatomis living along Indian Creek were upset that a settler named William Davis had dammed the creek, preventing fish from reaching their village. Davis ignored the protests, and assaulted a Potawatomi man who tried to dismantle the dam. The Black Hawk War provided the Indian Creek Potawatomis with an opportunity for revenge. On May 21, about fifty Potawatomis and three Sauks from the British Band attacked Davis's settlement, killing, scalping, and mutilating fifteen men, women, and children. Two teenage girls from the settlement were kidnapped and taken to Black Hawk's camp. A Ho-Chunk chief named White Crow negotiated their release two weeks later. Like other Rock River Ho-Chunks, White Crow was trying to placate the Americans while clandestinely aiding the British Band.
