Submarines from early days to modern (3)

This rather odd-looking device was the first vessel to attempt an underwater attack. Built by David Bushnell during the US War of Independence, it had room for one occupant and was appropriately called Turtle.
Propelled by handcranks but needing the cooperation of the tide, Turtle boasted an auger designed to attach an explosive charge to the bottom of a wooden ship. Ezra Lee was the brave soldier who attacked HMS Eagle. Fortunately for the Eagle and all who sailed in her, the auger broke. Lee also survived the attempt.
