Story of the Submarine

This book has been written for the nontechnical reader-for the man or boy who is interested in submarines and torpedoes, and would like to know something about the men who invented these things and how they came to do it. Much has been omitted that I should have liked to have put in, for this is a small book and the story of the submarine is much longer than most people realize. It is perhaps astonishing to think of the launching of an underseaboat in the year the Pilgrims landed at Plymouth Rock, or George Washington watching his submarine attack the British fleet in 1776. But are these things as astonishing as the thought of European soldiers wearing steel helmets and fighting with crossbows and catapults in 1916?
