Continental Army troops under Richard Montgomery and Benedict Arnold mounted a nighttime assault on the walled city of Quebec during a blizzard but were repulsed with heavy losses, ending the American bid to conquer Canada.

Summary

In late 1775, during the early stages of the American Revolutionary War, Continental Army leaders sought to secure Canada as a fourteenth colony and gain French-Canadian support against Britain. General Richard Montgomery advanced from Montreal while Colonel Benedict Arnold led a grueling march through Maine to join him outside Quebec City. On December 31, amid a fierce blizzard, the combined forces launched a nighttime assault on the heavily fortified city defended by Governor Guy Carleton. Montgomery was killed early in the attack, Arnold was wounded, and hundreds of Americans were captured after failing to breach the walls. The defeat ended the invasion of Canada and forced the survivors into a prolonged but ultimately unsuccessful siege.

Context

In the opening months of the American Revolutionary War, the Second Continental Congress authorized an invasion of the Province of Quebec in hopes of neutralizing a potential British base for operations against the rebellious colonies and perhaps adding Canada as a fourteenth colony. American leaders, including George Washington, believed that French-speaking Canadiens would welcome the invaders as liberators from British rule, an assumption rooted in longstanding tensions between the province’s Catholic majority and its Protestant administration. Two separate expeditions were planned: one under Philip Schuyler (later Richard Montgomery) advancing up the Champlain-Richelieu corridor toward Montreal, and a second under Benedict Arnold marching through the Maine wilderness directly toward Quebec City.

What Happened

Montgomery’s force captured Montreal on November 13, 1775, after which Governor Guy Carleton escaped downstream to reinforce Quebec. Arnold’s column of roughly 1,100 men endured extreme hardship on its trek through Maine, arriving outside the city in early December with about 600 effectives. The combined American army, numbering around 1,200, demanded the city’s surrender; Carleton refused. After a brief bombardment that proved ineffective, Montgomery decided on a desperate end-of-year attack to preempt the expiration of many enlistments.

Aftermath

On December 31, 1775, in driving snow, Montgomery’s column advanced along the St. Lawrence shore while Arnold’s men assaulted the northern approaches. Montgomery was killed almost immediately by cannon fire; Arnold was wounded in the leg early in his sector’s fighting. Daniel Morgan assumed command of the surviving elements but became trapped in the lower town and was forced to surrender along with more than 400 men. The remnants of the American force withdrew to a position outside the city and maintained a desultory blockade through the winter.

Legacy

The defeat at Quebec marked the first major reversal for the Continental Army and terminated the invasion of Canada. British control of the province remained intact, shaping the long-term boundary between the future United States and British North America. The campaign also exposed the severe logistical and climatic challenges of winter operations, lessons that influenced subsequent American strategy.

Why It Matters

The loss at Quebec halted American hopes of northward expansion and highlighted the challenges of winter campaigning and supply lines in the Revolutionary War. It preserved British control over Canada, shaping the future border between the emerging United States and British North America while boosting Loyalist sentiment in the region.
