Fort Lévis, a fortification on the St. Lawrence River, was built in 1759 by the French. They had decided that Fort de La Présentation was insufficient to defend their St. Lawrence River colonies against the British. Named for François Gaston de Lévis, Duc de Lévis, the fort was constructed on Isle Royale, 3 miles (4.8 km) downstream from the other fort. The fort surrendered after intense bombardment in August 1760 to the British and was renamed Fort William Augustus. The fort was abandoned in 1766. During the construction of the Saint Lawrence Seaway, the remains of the fort were destroyed and submerged beneath the waters of the river.

The Battle of the Thousand Islands was an engagement fought on 16–24 August 1760, in the upper St. Lawrence River, among the Thousand Islands, along the present day Canada–United States border, by British and French forces during the closing phases of the Seven Years' War, as it is called in Canada and Europe, or the French and Indian War as it is referred to in the United States. The engagement took place at Fort Lévis (about one mile (1.6 km) downstream from the modern Ogdensburg–Prescott International Bridge), Pointe au Baril (present-day Maitland, Ontario), and the surrounding waters and islands during the Montreal Campaign. The small French garrison at Fort Lévis held the much larger British army at bay for over a week, managing to sink two British warships and to cripple a third. Their resistance delayed the British advance to Montreal from the west.
