 By August 1760, only Pointe-au-Baril, Fort de La Présentation, and Montréal were left in French control along the upper St. Lawrence River.Pouchot, who had been captured at Fort Niagara and returned in a prisoner exchange, was sent to establish a new fort, Fort Lévis on an island in the St. Lawrence River, downstream from Fort de La Présentation.Due to Fort de La Présentation's location on low ground, the fort was susceptible to bombardment by British guns and Pouchot ordered its evacuation.
