7 Sep: The One Man Submarine

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. After exhausting hand-cranking through tidal currents, he managed to reach the ship, only to hit reinforced copper when he tried drilling into its hull. With the fuse already burning, he had no choice but to release the mine into the harbour, and row like mad…

In this episode, Arion, Rebecca and Olly explain why this farcical flop was still seen by some as a psychological victory; reveal what George Washington made of the whole madcap enterprise; and marvel at how from such clumsy beginnings grew one of the world’s most fearsome naval technologies…
