David Bushnell

There in the darkness of the depths of North River, this unnamed hero in the first practical submarine boat worked to make the first torpedo fast to the bottom of the enemy ship.

But a little iron plate or bolt holding the rudder in place made all the difference between a failure that few people ever heard of and a great achievement that would have made the inventor of the boat, David Bushnell, famous everywhere, and the navigator a great hero.

The little iron plate, however, prevented the screw from taking hold.

The tide carried the submarine past, and the chance was lost.

David Bushnell was too far ahead of his time.

His invention was not appreciated, and the failure of his first attempt prevented him from getting the support he needed to demonstrate the usefulness of his underwater craft.

The piece of iron in the keel of the British warship probably put back development of submarine boats many years, for Bushnell's boat contained many of the principles upon which the successful underwater craft of the present time are built.

All the great nations of the world have built fleets of submarines or are preparing to do so.

At last he reached his all-unsuspecting quarry, and sinking under the keel tried to attach the torpedo.

In the development of underwater fighting craft, France leads, as she has the largest fleet and was the first to encourage the designing and building of them.

It is now time to press on to the subject at hand.

Last time we discussed submarines from Genesis from David Bushnell's Turtle, which by the way, worked a lot better than I'd realized.

I mean, we discussed it on the channel from the perspective of not having quite worked because it didn't succeed in blowing up a British ship, but from a submarinal perspective, from being able to actually go under the water and so forth, it was a complete success.

Yes,

[instrumental music] Times have changed, and so has the man.

In the year 1775, a patriotic, enterprising American by the name of David Bushnell invented a strange craft.

It was constructed of two oak beams resembling two platters clapped together and propelled by a water screw attached to a hand-operated crank.

Another water screw regulated the depth to which the craft could descend.

Speaking of sleeping, let me tell you about one of the first experiments with submarines in military history.

During the War of Independence, when the Americans desperately tried to discover how to defeat the British Navy, an inventor named David Bushnell had an idea.

En 1775, se acercó al gobernador de Connecticut con planes para algo revolucionario.

Un submarino para una sola persona llamado Turtle.

To defeat the Royal Navy during the American Revolution, a rebel inventor designed a secret weapon, a bomb-carrying submarine.

David Bushnell developed the turtle submersible as a student at Yale University.

The vessel's attack on a British flagship failed, but the trailblazing boat's legacy endures 250 years later.

During the American Revolution, the Turtle made history as the world's first combat-ready submarine.

If all went according to plan, the driver of the acorn-shaped submersible, constructed out of oak and iron hoops, would descend, draw close enough to a warship to attach a bomb to its hull, and then make their escape by ascending to the surface.

Connecticut inventor David Bushnell designed the turtle as a secret weapon for the Patriots to wield against the British.

Nearly 250 years ago, on the night of September 6th, 7th, 1776, the vessel targeted the Royal Navy's flagship, the HMS Eagle, and failed.

In the centuries since, however, the story of the souped-up submersible that went up against the greatest navy in the world has served as a testament to the revolutionary spirit.

And these were sort of progenitors to submarines.

But then Genesis, the first submarine, was 1776, the American Revolution, David Bushnell.

This was the turtle and an absolutely brilliant design.

People tend to think of the turtle as being kind of silly looking and archaic.

So how did it work?

So it worked because of a number of astonishing inventions that are still used on submarines today.

And in fact, are still used on every boat in the world today because David Bushnell, for the turtle, invented the propeller.

He invented the propeller.
