The Turtle survived its famous night. It didn’t survive the month. Its inventor vanished for decades.

Weeks after the attack on the Eagle, the British caught up with the little machine the only way they could — by sinking the sloop carrying it up the Hudson. Bushnell wrote that he recovered his vessel. If he did, no one ever saw it again. The first combat submarine in history exists today only in letters: no drawing from Bushnell’s hand survives, and every replica in every museum is an educated guess built from words.

Bushnell wasn’t finished. In January 1778 he floated a swarm of his clockwork mines down the Delaware toward the British fleet at Philadelphia — kegs in the ice, drifting with the current. The attack sank little, but the sight of the Royal Navy blazing away at driftwood, barrels, and anything that bobbed delighted the American side so much that Francis Hopkinson — a signer of the Declaration — set it to verse. “The Battle of the Kegs” became one of the most popular satirical ballads of the war, sung in taverns up and down the coast. Bushnell had failed to sink the fleet and succeeded in making it ridiculous, which in a revolution is worth nearly as much.

Washington gave him command of the Army’s Corps of Sappers and Miners — the engineers — and after the war he sailed for France. Then the record simply stops. For years, nothing. When he surfaced again it was in Georgia, teaching school and practicing medicine under the name Dr. Bush. He lived out decades there in plain sight. His neighbors learned who the quiet doctor had been only after he died, when his papers gave him up.

Washington, asked years later about the strange machine of 1776, called it an effort of genius.

The man disappeared. The idea never did — ask Groton, thirty miles up the coast.
