The objective of the campaign was to gain military control of the British Province of Quebec, and convince the French-speaking Canadiens to join the revolution on the side of the Thirteen Colonies. One expedition left Fort Ticonderoga under Richard Montgomery, besieged and captured Fort St. Johns, and very nearly captured British General Guy Carleton when taking Montreal. The other expedition left Cambridge, Massachusetts under Benedict Arnold, and traveled with great difficulty through the wilderness of Maine to Quebec City. The two forces joined there, but were defeated at the Battle of Quebec in December 1775.
