The Battle of the Chateauguay was an engagement of the War of 1812. On 26 October 1813, a British force consisting of 1,630 regulars, volunteers and militia from Lower Canada and Mohawk warriors, commanded by Charles de Salaberry, repelled an American force of about 2,600 attempting to invade Lower Canada and ultimately attack Montreal. The Battle of the Chateauguay was one of the two battles (the other being the Battle of Crysler's Farm) which caused the Americans to abandon the Saint Lawrence Campaign, their major strategic effort in the autumn of 1813.
