The Battle of Plattsburgh, also known as the Battle of Lake Champlain, ended the final invasion of the northern states during the War of 1812. A British army under Lieutenant General Sir George Prévost and a naval squadron under Captain George Downie converged on the lakeside town of Plattsburgh, which was defended by American troops under Brigadier General Alexander Macomb and ships commanded by Master Commandant Thomas Macdonough. Downie's squadron attacked shortly after dawn on 11 September 1814, but was defeated after a hard fight in which Downie was killed. Prévost then abandoned the attack by land against Macomb's defences and retreated to Canada, stating that even if Plattsburgh was captured, it could not be supplied without control of the lake.
