Why did Bushnell’s submarines fail?
Bushnell is credited with creating the first submarine ever used in combat, while studying at Yale in 1775. He called it Turtle because of its look in the water.

Once the Turtle made its way to its target, the job was only half finished—the operator then had to deliver the ordnance. The Turtle ’s crank handle operated an external screw system whose controls were located in the vessel’s upper chamber. Attached to the screw was a waterproof fuse that led to the explosive charge.
The Battle of the Kegs
The Turtle saw action during two more battles at Fort Lee on the Hudson River, but again failed to inflict any damage. The prototype was subsequently destroyed when the tender that was transporting it back up the Hudson River was sunk by British artillery.
