Bushnell and fellow Yale University intellectual, Phineas Pratt, had conceived of the underwater bomb with a time delayed flintlock detonator. The one-man, hand-propelled sub was designed simply to transport the bomb to the enemy vessel. The American Turtle was successfully launched in the dark of night on September 6/7, 1776 against the British flagship, HMS Eagle, a 64 gun frigate moored in New York harbor off of the island now occupied by the Statue of Liberty. The Turtle had undergone extensive test trials in the safe colonial waters of the Connecticut River off Old Saybrook, Connecticut, piloted by the inventor's brother, Ezra Bushnell. Unfortunately, on the eve of the submarine's first combat mission, Ezra Bushnell died. With a freshly recruited, but less practiced pilot, Ezra Lee of Old Lyme, Connecticut, the American Turtle made its way underwater to the rudder of the Eagle's hull. Unfortunately, Lee first struck metal rather than wood with the screw intended to attach the bomb to the enemy's hull. After a second failed attempt, Lee propelled the American Turtle away, only to be observed and chased. The bomb was released into the water and resulted in a frightening explosion. While the American Turtle failed to destroy its target, the British recognized the threat and moved the fleet. Weather problems, and other operating difficulties prevented a successful attack by the submarine before it was scuttled by the British while being transported.Bushnell is a man of great mechanical powers, fertile in invention and a master of execution-- General George Washington, September 26, 1785
