The Battle of Lacolle Mills was fought on 30 March 1814 during the War of 1812. The small garrison of a British outpost position, aided by reinforcements, fought off a large American attack. Background After the St. Lawrence campaign had ended late the previous year with the British victory at the Battle of Crysler's Farm, the defeated American Army under Major General James Wilkinson went into winter quarters at French Mills, New York, only just inside the United States. The British commanders feared that the Americans could threaten the British line of communication along the St. Lawrence River from this position, but Wilkinson made no attempt to do so. His army arrived at French Mills with few supplies, and because of poor roads, lack of transport and draught animals and inefficiency of the Quartermaster General's Department, it was almost impossible to supply the army in this advanced position. Sickness rapidly increased until there were no less than 450 sick in squalid conditions in a hospital in Malone, New York and many more in French Mills. Finally, in late January, Secretary of War John Armstrong ordered Wilkinson to detach a division numbering 2,000 men under Brigadier General Jacob Brown to Sackett's Harbor, New York, and fall back with the main body (about 4,000 fit men) to Plattsburgh, New York on Lake Champlain, while the sick and wounded were removed to Burlington, Vermont. British troops followed up almost to Plattsburgh, recovering large quantities of supplies from settlements in New York state such as Malone and Four Corners and paroling many sick American soldiers who fell into their hands, before withdrawing. Wilkinson was aware that he would almost certainly be removed from command following the defeat of the St. Lawrence campaign, and planned several offensives to restore his reputation. Most of these were too ambitious with the means available, but one objective seemed feasible. A few miles north of the border between Canada and the United States, the main road running north crossed the small Lacolle River. Here, the British maintained an outpost of 80 men of the 13th Regiment of Foot in the Lacolle Mills Blockhouse and the stout stone-built watermill. The defenders also included a Congreve rocket detachment of the Royal Marine Artillery, and there were other outpost positions and blockhouses nearby. Battle Wilkinson marched northwards from Plattsburgh to attack this outpost on 27 March 1814. His force consisted of 4,000
