Which 1758 battle saw Montcalm defeat a much larger British force near Lake Champlain?

The 1758 battle in which Montcalm defeated a much larger British force near Lake Champlain was the Battle of Carillon.

Fought on July 8, 1758, near Fort Carillon—later renamed Fort Ticonderoga—the battle pitted roughly 3,600 to 4,000 French defenders against a British force of about 16,000 regulars, provincial troops, rangers, and allies under James Abercrombie. The French position stood between Lake George and Lake Champlain, guarding a vital portage route.

Montcalm’s troops strengthened their position with trenches and an abatis made from felled trees. Abercrombie ordered repeated frontal attacks without waiting for artillery, exposing British soldiers to concentrated fire from the entrenched defenders. The result was a major French victory and one of the bloodiest battles in the North American theater. It is often confused with the 1759 Battle of Ticonderoga, when the British captured the same strategic fort after the French withdrawal.
