Skirmishes at the Canard River
In the War of 1812, the first engagement in Canada involving British and American forces in significant numbers occurred here on the Canard River. On July 12, 1812, Brigadier-General William Hull invaded Canada and encamped near Sandwich. British commander, T.B. St. George, consolidated his forces consisting of regulars of the 41st Regiment, Indians, and Canadian militia at Fort Malden, south of the Canard and stationed at picquet at the bridge. This outpost was attacked on July 16th by Colonel Louis Cass and about 280 enemy troops. After a brief stand, the outnumbered British fell back towards the fort. The Americans abandoned the position the following day, but later returned several times to skirmish with the British, who reoccupied the post.
