Hunting the German shark

The 'shark killers' of the U. S. fleet The United States of America entered the First World War in April 1917, though its support for the allied war effort had, of course, been immensely influential in terms of the provision of material up to that point. The direct intervention of America in the war, with its vast resources of military personnel and equipment, backed by a huge manufacturing capacity, was inevitably pivotal. This account, part history, part anecdotal and part first hand account, was written shortly before the end of the conflict and describes in some detail the endeavours of the United States Navy during the war at sea in general and, more particularly, how it dealt with the omnipresent menace of the, 'German Shark'-the U Boats of the German Navy. This hidden undersea threat bore directly on America's role in the war.
