Wilhelm Bauer built his first submarine in 1850, but only narrowly escaped with his life after it sank in 50 feet of water during a demonstration. When later asked about the Turtle, George Washington replied, “I then thought, and still think, that it was an effort of genius…”ĭrawing of the Sea Devil on the ocean floor.
Bushnell later abandoned the submarine project after several other missions also failed to sink an enemy ship, but his invention earned him the respect of his fellow Patriots. Lee had only received minimal training, however, and after failing to attach a time bomb to the ship’s hull, he aborted the mission and detonated his mine in the open water. In the early morning hours of September 7, 1776, Continental Army soldier Ezra Lee launched history’s first submarine attack when he piloted the Turtle underneath the British warship HMS Eagle in New York Harbor. If operated properly, it could approach an enemy ship undetected and use a screw to plant a mine filled with 150 pounds of gunpowder. A pedal-operated water tank allowed it to submerge and surface, and lead ballast kept it upright in the water. This drawing lesson has come to an end and I hope you enjoyed it! Below you can view and download the PDF, which contains a short version of this lesson and other useful materials.During the American Revolution, inventor and Yale graduate David Bushnell provided the colonists with a secret weapon in the form of an experimental submarine called the “Turtle.” This one-man wooden craft relied on a human-powered hand crank and foot treadle for propulsion. To color this boat, use gray and different shades of blue. On the right and left sides of the previously drawn mast, draw two straight lines.Ĭonnect the lower ends of the two previously drawn lines to the mast with straight lines. In the middle of the boat, draw a straight line parallel to the line of the upper outline of the boat.ĭepict two straight vertical parallel lines and connect their upper ends with a short line. Now you should draw a straight horizontal line at the bottom of the drawing.Ĭonnect the two ends of the previously drawn lines with a curved line.Ĭonnect the second two ends of the previously drawn straight lines, using a rounded line. To complete this step, draw one straight slanted line.
