In 1961, this War of 1812 era, 12-pounder British long gun was found in the St. Lawrence River near Carleton Island. Similar cannon were standard armament on British 32-gun frigates' upper decks, or at Sackets Harbor on the corvette U.S.S. Madison and gun boats Ontario, Asp, Julia, and Hamilton. To fire the cannon, a 10-to-12 man crew used 4 pounds of black powder with solid, 12-pound iron round shot, bar shot, grape shot, or canister shot.
