This episode discusses America's first attempt at submarine warfare with 'The Turtle' and its historical significance.

America’s first attempt at submarine warfare set sail - or rather, sank - off the coast of New York on 7th September, 1776. ‘The Turtle’ was the brainchild of David Bushnell, a former Yale student who built a wooden, barrel-shaped craft secretly equipped to drill a hole in a British warship, and attach an explosive charge. The vessel had ballast tanks, a hand-cranked propeller, and a snorkel for air - giving the operator about 30 minutes of breathing time. For lighting, candles were too risky, so Bushnell used glow-in-the-dark fungus, which, unfortunately, stopped glowing in cold water. When the mission came, the Turtle’s pilot, infantryman Ezra Lee, paddled out to attack HMS Eagle.
