The next day, after an inconclusive skirmish at Kellogg's Grove, Black Hawk and his band fled the approaching militia through modern-day Wisconsin. The Sinsinawa Mound raid occurred on June 29, five days after the Battle of Apple River Fort. As the band fled the pursuing militia, they passed through what are now Beloit and Janesville, then followed the Rock River toward Horicon Marsh, where they headed west toward the Four Lakes region, near modern-day Madison. On July 21, 1832, the militia caught up with Black Hawk's band as they attempted to cross the Wisconsin River, near the present-day Town of Roxbury, in Dane County, Wisconsin, resulting in the Battle of Wisconsin Heights.
