when was the first submarine used
Today, we invent the submarine, against all odds. The University of Houston's College of Engineering presents this series about the machines that make our civilization run, and the people whose ingenuity created them. Bushnell's Turtle was the first submarine used in war. His one-man, hand-cranked machine did little harm to the English in 1776, but it made the point. One person who got the point was Robert Fulton. Years later, he made a submarine for the French and tried without success to sink the enemy with it.
