Assault on Quebec (1775)
The Assault on Quebec (31 December 1775) was a major action during the Invasion of Canada (1775) in the early phase of the American Revolutionary War. Continental Army and militia forces led by Richard Montgomery and Benedict Arnold attempted to capture Quebec City from forces loyal to the Kingdom of Great Britain under Guy Carleton. The assault failed, producing heavy losses for the United Colonies and ensuring continued British control of the provincial capital.
Background
In 1775 the Continental Congress authorized an expedition to bring Quebec into rebellion, motivated by strategic concerns related to the Thirteen Colonies and the potential for French-Canadian support. Two converging American columns—one commanded by Richard Montgomery advancing from Lake Champlain after the capture of Fort Saint-Jean and Fort Ticonderoga, and another led by Benedict Arnold arriving after a grueling overland march from New Hampshire and Maine via the Kennebec River and the Chaudière River—joined near Quebec City in November and December 1775. Earlier actions, including the capture of Montreal and the Siege of Fort Saint-Jean, had raised hopes among leading revolutionaries such as John Adams and Thomas Jefferson that Quebec might join the Patriot cause. However, Carleton retained a defensive force in Quebec City bolstered by regulars from regiments such as the 33rd Regiment of Foot and local militia loyal to the Crown.
British and American forces
American forces assembled for the assault comprised Continental regulars, volunteer militia, and detachments from units raised in New York, New Hampshire, Connecticut, and Massachusetts Bay Colony. Key American leaders included Richard Montgomery, recently promoted and noted for his capture of Montreal; Benedict Arnold, famed for his expedition and aggressive temperament; and field officers like Daniel Morgan, whose riflemen had earlier distinguished themselves at Fort Ticonderoga. Opposing them, Carleton commanded a garrison of British regulars, including officers such as James Murray and tactical support from experienced commanders like John Burgoyne, plus locally raised Canadian militia and Indigenous allies. Fortifications around Quebec City—notably the Cap Diamant heights, the Saint Lawrence River batteries, and the old Plains of Abraham defenses—favored the defenders.
The assault and key engagements
On the evening of 30 December 1775, Continental leaders planned a coordinated night attack designed to surprise the defenders and take key positions before dawn. The assault comprised multiple columns: one led by Richard Montgomery aimed at the Lower Town via the Saint Lawrence River approach, another under Benedict Arnold targeting the Saint Louis Gate and Cape Diamond slopes, and supporting attacks by militia and light troops including detachments of Daniel Morgan's riflemen. Heavy winter weather, darkness, and unfamiliarity with the labyrinthine streets complicated coordination. Montgomery's column managed to penetrate parts of the Lower Town and initially routed some defenders, but Montgomery was killed during an engagement near the city defenses after coming under fire from troops commanded by Murray and guarded detachments. Simultaneously, Arnold, wounded in the leg during fierce fighting around the Saint Louis Gate, was unable to press his advantage. Panic, confusion, and the rallying of British regulars and militia under Carleton turned the tide; counterattacks and sharpshooting from the St. Lawrence batteries isolated American columns, leading to heavy American casualties and captures.
Casualties and immediate aftermath
American losses were severe: estimates place killed, wounded, and captured between 400 and 600, including the loss of their chief commander Richard Montgomery and the wounding of Benedict Arnold. British and loyalist casualties were lower but significant, with perhaps 200–500 killed, wounded, or missing, and several officers and militia members among the dead. Following the failed assault, besieging American forces remained in the environs of Quebec City through the winter but suffered from disease—particularly smallpox—and supply shortages exacerbated by the onset of the Great Blizzard of 1775–76 conditions and British naval control of the Saint Lawrence River resupply routes. Carleton's successful defense preserved British lines of communication to Halifax, Nova Scotia and allowed reinforcement by units from Ireland and Britain in subsequent months.
Strategic consequences and legacy
The failed assault marked a turning point in the Invasion of Canada (1775) campaign, extinguishing American hopes of quickly bringing Quebec into the revolutionary fold and compelling the Continental Congress to divert resources elsewhere. The defense secured by Carleton maintained British control of a key northern bastion, influencing later operations by commanders such as John Burgoyne during the Saratoga campaign of 1777. The event cemented the reputations of figures like Benedict Arnold—whose later career would include the Arnold treason episode—and memorialized the sacrifice of Richard Montgomery in American revolutionary memory, including monuments in New York City and Montreal. Long-term, British retention of Quebec City helped preserve British North America's territorial integrity, shaping subsequent diplomatic outcomes including discussions at the Treaty of Paris (1783) and the evolving relationship between the United States and the future Canada.
