FIGHTING UNDER THE SEA

Since the 16th century men have been designing propelled devices for traveling underwater and some of the best of this hopscotch history of sub warfare is the review of those daring young men in their submersible machines. It took our Civil War for the technological big push, then followed by the invention of the torpedo--essentially the same torpedo we have today. W.W.I proved the sub's effectiveness and W.W.II confirmed it. Though this is a British book, Uncle Sam's subs in the Japanese-held South Pacific round out the brief chronicle.
