Battle of Trois-Rivières

The Battle of Trois-Rivières was fought on June 8, 1776, during the American Revolutionary War. A British army under Quebec Governor Guy Carleton defeated an attempt by units from the Continental Army under the command of Brigadier General William Thompson to stop a British advance up the Saint Lawrence River valley. The battle occurred as a part of the American colonists' invasion of Quebec, which had begun in September 1775 with the goal of removing the province from British rule.

The crossing of the Saint Lawrence by the American troops was observed by Quebec militia, who alerted British troops at Trois-Rivières. A local farmer led the Americans into a swamp, enabling the British to land additional forces in the village, and to establish positions behind the American army. After a brief exchange between an established British line and American troops emerging from the swamp, the Americans broke into a somewhat disorganized retreat. As some avenues of retreat were cut off, the British took a sizable number of prisoners, including General Thompson and much of his staff.

This was the last battle of the war fought on Quebec soil. Following the defeat, the remainder of the American forces, under the command of John Sullivan, retreated, first to Fort Saint-Jean, and then to Fort Ticonderoga.
