Beginning on December 8, 1775, Colonel Benedict Arnold and General Richard Montgomery lead an American force in the siege of Quebec. The Americans hoped to capture the British-occupied city and with it win support for the American cause in Canada.
In June, Congress decided to send two columns of 1,000 men each towards Canada. General Richard Montgomery proceeded up Lake Champlain and successfully captured Montreal in November before reaching Quebec City. Colonel Benedict Arnold led his men through the woods of Maine, approaching the city directly. On November 14, Arnold arrived on the Plains of Abraham outside the city of Quebec; his men sustained themselves upon dog meat and leather in the cold winter. The 100 men defending the city refused to either surrender to Arnold or leave their defenses to fight them on open plains, so Arnold waited for Montgomery to join him with his troops and supplies at the beginning of December.
The royal governor general of Canada, Sir Guy Carleton, had managed to escape Montgomery’s early successful attacks. He snuck into Quebec, organized 1,800 men for the city’s defense, and prepared to wait out the Patriots’ siege. But Arnold and Montgomery faced a deadline as their troops’ enlistments expired at the end of the year. On December 7, Montgomery fired arrows over the city walls bearing letters demanding Carleton’s surrender. When Carleton did not acquiesce, the Americans began a bombardment of the city with Montgomery’s cannon on December 8. They then attempted a disastrous failed assault on December 31, in which Montgomery was killed and Arnold seriously wounded.
