Battle of Beaver Dams![]() ![]() ![]() ![]() The Battle of Beaver Dams took place on 24 June 1813, during the War of 1812. An American column marched from Fort George and attempted to surprise a British outpost at Beaver Dams, billeting themselves overnight in the village of Queenston, Ontario. Laura Secord, a resident of Queenston, had earlier learned of the American plans, and had struck out on a long and difficult trek to warn the British at Decou's stone house near present-day Brock University. When the Americans resumed their march, they were ambushed by Native warriors and eventually surrendered to the commander of a small British detachment. About 500 Americans, including their wounded commander, were taken prisoner. |
