After the American forces had retreated from Quebec on 6 May 1776, British Major-General John Burgoyne assembled his troops and advanced toward Montreal. As the British and Canadian force approached Trois-Rivières, American General William Thompson decided not to engage Burgoyne's force. The Americans hurriedly withdrew from Trois-Rivières on 8 July 1776. Throughout July, American troops abandoned the St. Lawrence Valley, and, by the end of the month, all American troops had withdrawn from Canada. Major-General Burgoyne planned an offensive into New York for the following spring.
The British and Canadian forces had successfully thwarted a determined American attempt to conquer Canada. For the remainder of the American Revolution, battles would be fought in the Thirteen Colonies to the south.
