American Turtle

American Turtle was a submarine used during the American Revolutionary War by the Continental Army to attack HMS Eagle (1774), a British Royal Navy ship. The vessel was designed by David Bushnell, an American inventor and engineer, with the help of Benjamin Franklin and Isaac Doolittle. The American Turtle was the first submarine to be used in a military operation, and its design and construction paved the way for the development of modern submarines used by United States Navy, Royal Navy, and other naval forces, including those of France, Germany, and Japan. The American Turtle's operational history is closely tied to the Battle of Long Island and the New York Campaign.

Introduction

The American Turtle was a hand-powered submarine that was built in 1775 by David Bushnell and his brother Ezra Bushnell in Old Saybrook, Connecticut. The vessel was designed to attack British Royal Navy ships in New York Harbor during the American Revolutionary War. The American Turtle was made of oak wood and was approximately 7 feet (2.1 meters) long and 3 feet (0.9 meters) wide. It was powered by a hand-cranked screw propeller and had a crew of one, who would use a breathing tube to breathe while underwater. The American Turtle was also equipped with a keg of gunpowder that was designed to be attached to the hull of an enemy ship and detonated. The development of the American Turtle was influenced by the work of Leonardo da Vinci, Nathaniel Symons, and other inventors and engineers who had experimented with submarine design, including Cornelius Drebbel and Blaise Pascal.

Design_and_Construction

The design and construction of the American Turtle were influenced by the work of inventors and engineers such as Robert Fulton, Isambard Kingdom Brunel, and William Symington. The vessel was built using wooden planks and was caulked with oakum to make it watertight. The American Turtle had a ballast tank that was used to control its buoyancy, and it was equipped with a rudder and a screw propeller that were powered by a hand-crank. The vessel was also equipped with a compass and a depth gauge that were used to navigate and control its depth. The design of the American Turtle was also influenced by the work of mathematicians and scientists such as Archimedes, Galileo Galilei, and Isaac Newton, who had studied the principles of fluid dynamics and hydrostatics. The construction of the American Turtle was supported by George Washington, Thomas Jefferson, and other Founding Fathers who recognized the potential of submarines in naval warfare, including John Adams and Benjamin Franklin.

Operational_History

The American Turtle was used in a military operation on September 7, 1776, when it was launched in New York Harbor to attack the HMS Eagle (1774), a British Royal Navy ship. The vessel was crewed by Sergeant Ezra Lee, a Continental Army soldier who had been trained to operate the submarine. The American Turtle was able to approach the HMS Eagle (1774) undetected, but it was unable to attach the keg of gunpowder to the hull of the ship. The American Turtle was forced to retreat after the HMS Eagle (1774) discovered it and launched a counterattack. The operational history of the American Turtle is closely tied to the Battle of Long Island and the New York Campaign, and it is considered to be one of the first submarine attacks in history, along with the CSS Hunley and the U-47 (1938). The American Turtle's operational history has been studied by historians and military strategists such as Alfred Thayer Mahan and Carl von Clausewitz, who have analyzed its impact on the development of naval warfare, including the Battle of Trafalgar and the Battle of Jutland.

Legacy

The American Turtle has had a significant impact on the development of submarines and naval warfare, influencing the design of submarines used by the United States Navy, Royal Navy, and other naval forces, including those of France, Germany, and Japan. The vessel's design and construction paved the way for the development of modern submarines that are used today, including the Los Angeles-class submarine and the Virginia-class submarine. The American Turtle is also considered to be an important part of American history and is remembered as a symbol of American ingenuity and patriotism, along with other American symbols such as the Statue of Liberty and the American flag. The legacy of the American Turtle has been recognized by institutions such as the United States Naval Academy, the National Maritime Museum, and the Smithsonian Institution, which have preserved and exhibited the vessel's remains, along with other historical artifacts such as the USS Constitution and the HMS Victory. The American Turtle's legacy continues to be studied by historians and military strategists such as Samuel Eliot Morison and John Keegan, who have analyzed its impact on the development of naval warfare, including the Battle of Midway and the Battle of the Atlantic.
