Quebeckers living in the forts of the Great Lakes region also massively sided with the Patriots and were instrumental in the taking of the fort by the Patriots. Major Clément Gosselin, Pierre Ayotte, Antoine Paulin, Louis Gosselin, Germain Dionne, Pierre Douville, Edward Antill and Moses Hazen and 747 Quebec militiamen were all in Quebec when they joined the Patriots and defeated the British at Yorktown in 1781. In a key act leading up to the Siege of Yorktown, Louis-Philippe de Vaudreuil, the French-born nephew of French Canada's last French governor, the Marquis de Vaudreuil, assisted Bougainville and de Grasse in preventing the British Navy from resupplying or relieving Cornwallis' army in the Battle of the Chesapeake.
