Submarine warfare isn’t the type of combat that generally comes to mind when one thinks of the Revolutionary War, but then again the United States only had one type of submarine back then … and it generally failed.
Although Mount Vernon doesn’t have an original submarine – or even a replica – it does have a correspondence between George Washington and Thomas Jefferson about the submarine, which was created by a man named David Bushnell in 1775. The letter goes as follows:
Paris July 17. 1785.
Sir
Permit me to add, what I forgot in my former letter, a request to you to be so kind as to communicate to me what you can recollect of Bushnel’s experiments in submarine navigation during the late war, and whether you think his method capable of being used successfully for the destruction of vessels of war. It’s not having been actually used for this purpose by us, who were so peculiarly in want of such an agent seems to prove it did not promise success. I am with the highest esteem Sir Your most obedt & most humble servt
Th: Jefferson
The aptly-named one-man submarine that Jefferson speaks of was called the Turtle because it resembled two tortoise shells joined together. The contraption was invented after Bushnell, then a student at Yale University, discovered that gunpowder could explode underwater. Constructed from oak, iron bands and pitch, the Turtle was approximately 7 feet tall, with an air supply lasting about 30 minutes, and it was maneuvered using a hand-powered propeller.
As for Jefferson’s query on whether submarine navigation was a “method capable of being used successfully for the destruction of vessels of war,” Washington replied that while he thought it was “an effort of genius,” there were many dangers faced by the operator, and these had led to failure.
In the end, the Turtle was not a successful creature, as is exemplified in its first tour in battle.
On the night of September 6, 1776, the Turtle attacked the British HMS Eagle in New York harbor. Once on the underside of the ship, the Turtle attempted to drill a hole in the hull to secure a time-delay explosive, but it turned out the hull was copper-plated and impenetrable. As the submarine retreated it was spotted by the British and the Turtle‘s captain released a torpedo, alarming the British who retreated. Attempted attacks on British ships continued to fail through 1777, when the project was abandoned.
Jefferson’s letter will be on display through August 14 in the Bringing Them Home exhibition in the Donald W. Reynolds Museum and Education Center.
