Moses Hazen was a brigadier general in the Continental Army during the American Revolutionary War. Born in the Province of Massachusetts Bay, he saw action in the French and Indian War with Rogers' Rangers. His service included particularly brutal raids, during the Expulsion of the Acadians and the 1759 Battle of Quebec. He was formally commissioned into the British Army, shortly before the war ended, and retired on half-pay outside Montreal, Province of Quebec, where he and Gabriel Christie, another British officer, made extensive land purchases in partnership. During his lifetime he acquired land in Quebec, New Hampshire, Vermont, and New York, but lost most of his Quebec land due to litigation, with Christie and the negative effects of the Revolution.

The Invasion of Quebec was the first major military initiative by the newly formed Continental Army during the American Revolutionary War. The objective of the campaign was to seize the Province of Quebec from Great Britain, and persuade 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, under Benedict Arnold, left Cambridge, Massachusetts, and traveled with great difficulty through the wilderness of Maine to Quebec City. The two forces joined there, but they were defeated at the Battle of Quebec in December 1775.
