The Turtle
  • The first American submarine was the Turtle designed and built by Connecticut inventor David Bushnell during the American Revolution. The Turtle was a one-man hand-powered wooden submarine. It resembled the shape of an almond, or two turtle shells placed together.
  • The Turtle was the first submarine in history used in combat.
  • Just after midnight, September 7, 1776, the Turtle unsuccessfully attacked the HMS Eagle in New York Harbor.
  • George Washington was so impressed with the Turtle's performance; he called Bushnell a "man of great mechanical powers, fertile in invention and a master of execution."
