Siege of Fort St. Jean

Battle context

The Siege of Fort St. Jean was a key early operation in the American invasion of Quebec during the Revolutionary War. Conducted by Brigadier General Richard Montgomery against the British garrison at Saint-Jean, the siege occupied a significant stretch of the 1775 campaign season, running from September 17 to November 3. The prolonged duration of the siege consumed time and resources that constrained subsequent American operations deeper into Quebec, though it represented a necessary step in Montgomery's northward push toward Montreal and ultimately Quebec City. The investment of Saint-Jean by a force of 1,500 Continental troops, under commanders including Montgomery, David Wooster, and James Livingston, reflected the American effort to neutralize British defensive positions along the Richelieu River corridor before advancing further into the province.
