Châteauguay played an important part in the colonial history of North America. With the United States having declared war on Britain in 1812, Châteauguay was seen as little more than a good vantage point to post troops to defend Montreal against an invasion. This prong of the American advance on Montreal ended with the Battle of the Châteauguay, where on October 26, 1813, Lieutenant Colonel Charles de Salaberry succeeded in halting the American force of 4,000 advancing on Montreal with only some 400 troops, mostly French-Canadian and 170 Kahnawake Mohawk warriors. The second American incursion towards Montreal was defeated shortly after at Crysler's Farm on November 11.
