Ezra Lee (August 1749 – October 29, 1821) was an American colonial soldier, best known for commanding the Turtle submarine.
Lee was born in Lyme, Connecticut. In August 1776 he was selected by brother-in-law Brigadier General Samuel Holden Parsons, also of Lyme, as one of several volunteers to learn to operate the Turtle, an early submarine invented by Saybrook, Connecticut, native David Bushnell. When General George Washington authorized an attack on British Admiral Richard Howe's flagship HMS Eagle, then lying in New York harbor, Lee was chosen to operate the "infernal machine".
Sergeant Lee piloted the Turtle up to the Eagle, which was moored off what is today called Governors Island, due south of Manhattan. A common misconception was that Lee failed because he could not manage to bore through the copper-sheeted hull. In practice, it has been shown that the thin copper would not have presented any problem to the drill, and that he likely struck a metal rudder support.
A more likely scenario is that Lee's unfamiliarity with the vessel made him unable to keep the Turtle stable enough to work the drill against the Eagle's hull. When he attempted another spot in the hull, he was unable to stay beneath the ship, and eventually abandoned the attempt. Governors Island is off the southern vertex of Manhattan, this is the place where the Hudson River and the East River merge. The currents at this point would be strong and complex. The Turtle would only be able to attack ship moored here during the short period of time when the incoming tide balanced the river currents. It is possible that during the attack the tide turned and Lee was unable to compensate. He released the keg of gunpowder when British in row boats attempted to pursue him. The British, suspecting some trick, gave up their pursuit.
Lee landed safely after remaining several hours in the water, and received the congratulations of Washington, who afterwards employed him on secret service. Lee made a similar attempt a short time afterward with Bushnell's machine in an attempt to destroy a British frigate that lay opposite the village of Bloomingdale, but was discovered and compelled to abandon the enterprise. The submarine was soon after sunk by the British as it sat on its tender vessel, in Fort Lee, New Jersey. Years later in a letter to Thomas Jefferson, Bushnell reported he had salvaged the Turtle; its final fate is unknown.
