Battle of the Windmill National Historic Site

The Battle of the Windmill was fought in November 1838 in the aftermath of the Upper Canada Rebellion. Loyalist forces of the Upper Canadian government and American troops, aided by the Royal Navy and the United States Navy, defeated an invasion by militants of a United States clandestine organization known as Hunter Patriots. The insurgents had intended using Windmill Point as a base for further offensives into Canada. Canadian, British, and American troops thwarted the invasion, successfully defending Canadian soil and forced the invaders to surrender. Others still in the U.S. were captured and arrested by U.S. officials.
