Ezra Lee is best known for being the first submarine commander. In the Revolutionary War he operated David Bushnell's submarine called the Turtle to attack a British ship docked in New York harbor. David Bushnell’s Turtle, built in 1775, was the first American submarine. The Turtle was powered by a hand-driven propeller. This 1875 drawing by Lt. Francis Barber is the most familiar rendering of Turtle. However, it contains several errors, including internal ballast tanks and helical screw propellers.
