General William Hull, commander of the U.S. Army of the Northwest, ordered the evacuation of Fort Dearborn amid escalating tensions during the War of 1812. U.S. troops, militia, and Miami auxiliaries were withdrawing from the fort in the Chicago area of Illinois Territory when they encountered Potawatomi warriors.
On August 15, 1812, U.S. forces and settlers evacuating Fort Dearborn were attacked by Potawatomi warriors near the fort. The engagement lasted roughly 15 minutes and ended in a complete Potawatomi victory. Survivors were taken captive; some were later ransomed. Fort Dearborn was subsequently burned.
The defeat hardened U.S. federal policy toward Native Americans in the region, convincing the government that all Indigenous peoples must be removed from territories near American settlements. Fort Dearborn was eventually rebuilt in 1816, marking renewed American commitment to controlling the Chicago area.
