On this date in 1832, the fortunes of American Indians in Illinois, Iowa and Michigan Territory took a significant turn for the worse. On August 1-2 of that year, the final confrontation of the Black Hawk War took place just south of the Bad Axe River in the western region of modern day Wisconsin. The result was as decisive as the Battle of Fallen Timbers (1794) had been for the Indians of the Ohio River Valley, or the Battle of Horseshoe Bend (1814) had been for the Creeks. Though it is often overshadowed by the drama of the Cherokee removal, the Black Hawk War was no less critical to the history of Indian peoples east of the Mississippi.
