At the onset of the American Revolution, the British expected to quell the rebellion quickly with a show of overwhelming force. In an experiment in asymmetric warfare, David Bushnell created the first submarine vessel designed specifically “for the destruction of vessels of war”. On a quiet September night in 1776, sergeant Ezra Lee maneuvered Bushnell’s strange little craft out from Manhattan and into the midst of the greatest naval fleet ever assembled in the Americas. Lee’s goal was to sink the British flagship HMS Eagle by attaching a powerful explosive to its hull. Although the mission was unsuccessful, Bushnell’s concept of submarine warfare was considered by George Washington to have been “an effort of genius”.

More than two centuries later, under the direction of technical arts teacher Frederic J. Frese, students at Old Saybrook High School created a working replica of Bushnell’s submarine, facilitated through an education partnership with the Naval Undersea Warfare Center in Newport, Rhode Island, where Roy R. Manstan was a mechanical engineer and Navy trained diver.

In Turtle: David Bushnell’s Revolutionary Vessel, the authors provide new insight into Bushnell’s “engine of devastation”, tracing the history of undersea warfare before Bushnell and the origin of the many innovations Bushnell understood would be necessary for conducting a covert submarine attack. The knowledge gained from testing the Turtle replica enabled the authors to speculate as to what America’s first submariner Ezra Lee experienced that September night and what may have caused the attack to fail.
