In late August, Montgomery sailed north from Fort Ticonderoga with about 1,200 men. After successfully besieging Fort Saint-Jean, he captured Montreal on November 13. The two men joined forces in early December, and with their combined force of about 1,200 soldiers, they attacked Quebec on December 31, 1775. The colonial forces suffered a disastrous defeat at the hands of General Guy Carleton, governor of Quebec and commander of the British forces. Montgomery was killed leading an assault along with all but one of his officers; his men never got close to the walls. Arnold's force made a descent into the lower town. Early in the battle, Arnold was wounded in the leg, but stayed on the battlefield encouraging his troops on. Daniel Morgan's rifle company, the most successful of the American troops, fought inside the city until Morgan was cornered and forced to surrender. Many others were killed or wounded, and hundreds were taken prisoner.
