Cause

Ethan Allen, tasked only with recruiting Quebec militia during the American invasion of Canada, saw an opportunity to seize the lightly defended city of Montreal. He coordinated with Major John Brown, who was supposed to provide reinforcing troops, and crossed the St. Lawrence River with roughly 110 American and Quebec militia fighters.

Event

On September 25, 1775, Allen's force crossed the St. Lawrence to the north shore near Longue-Pointe. Brown's promised reinforcements never arrived. British General Guy Carleton dispatched a predominantly Quebec militia force that cut off Allen's retreat, surrounded his isolated men, and captured Allen along with a number of his soldiers.

Consequence

Allen was transported as a prisoner to England and later to New York City, remaining in captivity until his exchange in 1778. Despite this setback, Carleton ultimately abandoned Montreal, and Continental Army forces occupied the city without a fight on November 13, 1775, achieving the strategic objective Allen had failed to take by force.
