The War of 1812 was fought in four major theaters: the Atlantic Coast, the Canada–US border, the Gulf Coast, and the American West. There were also numerous naval battles at sea, almost all of them in the Atlantic. Actions along the Canadian border occurred in three sectors (from west to east): the old Territory, the Niagara Frontier, and the St. Lawrence River.[a]
