Seth Warner was an American soldier. He was a Revolutionary War officer from Vermont who rose to the rank of Continental colonel and was often given the duties of a brigade commander. He is best known for his leadership in the capture of Fort Crown Point, the Battle of Longueuil, the siege of Quebec, the retreat from Canada, and the battles of Hubbardton and Bennington.

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.
