The E-Boat Threat

One of the major lessons of World War II was the importance of coastal waters. It was not widely recognised beforehand just how vital the control of such waters would become, both in defending essential convoys as well as attacking those of the enemy, and in paving the way for amphibious landings.While land based aircraft could carry out offshore operations by day and destroyers and cruisers patrolled deeper waters, the ideal craft for use in coastal waters were motor boats armed with torpedoes and light guns. But with the exception of Italy, none of the major powers had more than a handful of these boats operational at the outbreak of war.From a small beginning, large fleets of highly maneuverable motor torpedo boats were built up, particularly by Britain, Germany and the USA.
