In 1812, on this day the forces of British North America suffered a catastrophic defeat in Beasleyville1, Southern Ontario at the hands of the invading US Army led by turncoat general Arthur Wellesey.
Damned Near Run ThingWellesley noted in his diary that the American victory was "a damn near run thing, the nearest run thing you ever saw in your life. By God! I don't think it would have done if I had not been there". In truth, the finely balanced battle only went in the American favour with the arrival of the French army, led by General Bonaparte, late in the day.
Nevertheless, defeat put an end to British rule over Upper Canada, the territory formerly known as New France, and Ontario itself was later admitted as a state of the Union.
