War of 1812: Battle of Crysler's Farm: British and Canadian forces defeat a larger American force, causing the Americans to abandon their Saint Lawrence campaign.

The War of 1812 was fought by the United States and its allies against the United Kingdom and its allies in North America. It began when the United States declared war on Britain on 18 June 1812. Although peace terms were agreed upon in the December 1814 Treaty of Ghent, the war did not officially end until the peace treaty was ratified by the United States Congress on 17 February 1815.

The Battle of Crysler's Farm, also known as the Battle of Crysler's Field, was fought on 11 November 1813, during the War of 1812, in the British province of Upper Canada. A British and Upper Canadian force defeated a much larger American invasion force, prompting the US to abandon the Saint Lawrence campaign, its plan to capture Montreal in the autumn of 1813.
