HMS Canceaux was a sloop active in both the hydrographic exploration of the Atlantic Canada and New England coastline and in the American Revolutionary War. She played an integral role in the battle for control of Maine, in particular at the Burning of Falmouth. She began her life as a merchant vessel and would eventually be transformed to a military vessel for the Royal Navy, equipped to command the razing of major settlements. After leaving the Saint Lawrence River estuary in 1771, Canceaux actively shaped the maritime history of the American Revolution.
