Summary of Operations in the North 1812-1814

1812-06-18/1814-12-31

British and American leaders placed great importance on gaining control of the Great Lakes and the St. Lawrence River because of the difficulties of land-based communication. The British already had a small squadron of warships on Lake Ontario when the war began and had the initial advantage. The Americans established a Navy yard at Sackett's Harbor, New York, a port on Lake Ontario. Commodore Isaac Chauncey took charge of the thousands of sailors and shipwrights assigned there and recruited more from New York. They completed a warship (the corvette USS Madison) in 45 days. Ultimately, almost 3,000 men at the shipyard built 11 warships and many smaller boats and transports.
