We acquired this map in October 2020 from the descendants of James Sever, Captain of the USS Congress, one of the famed first six frigates of the U.S. Navy. Captain Sever was born in 1761, attended Harvard, and upon graduation received an ensign's commission in the 7th Massachusetts Regiment (February 1, 1781) during the Revolutionary War. Sever later transferred to the 4th Massachusetts Regiment and remained in the Continental Army until June 20, 1784. Sever was from a successful Massachusetts merchant family, and that background along with his military experience was enough for him to be named the superintendent of the USS Congress during its construction in 1795. In 1798, he became one of the first six post captains of the U.S. Navy. Sever served in the first foreign action of the U.S. Navy, when the Congress was involved in privateer hunting in the Caribbean and the U.S. intervention in the Haitian War of Knives. Sever had a relatively short career in the Navy and was dismissed during Jefferson's purge of the officer corps in 1801.
