The Penobscot Expedition was a 44-ship American naval armada during the Revolutionary War assembled by the Provincial Congress of the Province of Massachusetts Bay. The flotilla of 19 warships and 25 support vessels sailed from Boston on July 19, 1779, for the upper Penobscot Bay in the District of Maine carrying an expeditionary force of more than 1,000 American colonial marines and militiamen. Also included was a 100-man artillery detachment under the command of Lt. Colonel Paul Revere.

The Continental Navy was the navy of the Thirteen Colonies during the American Revolutionary War. Founded on October 13, 1775, the fleet developed into a relatively substantial force throughout the Revolutionary War, owing partially to the substantial efforts of the Continental Navy's patrons within the Continental Congress. These Congressional Patrons included the likes of John Adams, who served as the Chairman of the Naval Committee until 1776, when Commodore Esek Hopkins received instruction from the Continental Congress to assume command of the force.
