On May 10, 1775, shortly after the American Revolutionary War began, Benedict Arnold and Ethan Allen led an expedition that captured Fort Ticonderoga on Lake Champlain in the British Province of New York. Allen and Arnold were aware that Quebec was lightly defended; there were only about 600 regular troops in the entire province. Arnold, who had done business in the province before the war, also had intelligence that the French-speaking Canadiens would be favorably disposed toward a colonial force.
