With hostilities now underway, and few allies to depend upon, Black Hawk sought a place of refuge for the women, children, and elderly in his band. Accepting an offer from the Rock River Ho-Chunks, the band traveled further upriver to Lake Koshkonong in the Michigan Territory and camped in an isolated place known as the "Island". With the non-combatants secure, members of the British Band, with a number of Ho-Chunk and Potawatomi allies, began raiding white settlers. Not all Native Americans in the region supported this turn of events; most notably, Potawatomi chief Shabonna rode throughout the settlements, warning whites of the impending attacks.
