On November 3, 1775, after enduring a grueling six-week siege, Major Charles Preston raised the white flag over Fort St. Jean in Quebec. The surrender of this strategic British stronghold to American General Richard Montgomery marked a pivotal moment in the early stages of the American Revolutionary War and opened the gateway to Montreal. The capitulation represented not merely the fall of a fortification, but the crumbling of Britain's defensive line protecting the heart of its Canadian colony.
