What happened during the American attack on Quebec city in 1775?

During the American Revolution, the American attack on Quebec City on December 31, 1775, was an unsuccessful attempt by Revolutionary forces to capture the British stronghold.12

Following the capture of Montreal in November 1775, American forces led by General Richard Montgomery and Colonel Benedict Arnold converged on Quebec. Arnold had previously led a difficult expedition through the Maine wilderness to reach the city. By the time of the assault, the American force consisted of approximately 1,675 troops, many of whom were suffering from expired enlistments.21

The attack resulted in a complete defeat for the Americans. General Montgomery was killed during the fighting, and a large number of colonial soldiers were captured. Although the Americans maintained a siege of the city throughout the winter, they were ultimately forced to withdraw in the spring of 1776 upon the arrival of British reinforcements. This failed expedition effectively ended American military efforts in Canada during the conflict.12
