| The
Background:
The Turtle was the world's first combat submarine.
It was built by a Connecticut man in 1776, and was sent against a British
warship in the harbor of New York City.
The submarine reached the ship, but the drill bit could
not penetrate a copper plate attached to the wooden hull of the British
warship. As a result, the torpedo could not be attached. (Modern
torpedoes are self-propelled, of course.)
Students should study the drawing, and label the parts
of the submarine. There are articles with more drawings of the Turtle
in many encyclopedias - look under submarines, history. There are
also a number of interesting Internet sites with more details about the
submarine.
