The Battle of Stoney Creek was fought on 6 June 1813, during the War of 1812 near what is now Stoney Creek, Ontario, Canada. British units made a night attack on the American encampment, and due in large part to the capture of the two senior officers of the American force and an overestimation of British strength by the Americans, the outcome of the battle was a victory for the British, and a turning point in the defence of Upper Canada.
