Restricted by the terms of the Treaty of Versailles, the German Kriegsmarine exploited a loophole by designing a fleet of fast, wooden-hulled attack craft they referred to as Schnellboots. Expertly designed, these vessels were perfected over time and by the outbreak of the Second World War, they had become a devastatingly effective part of Germany’s naval strength. Powered by three diesel engines and featuring a triple rudder arrangement, Germany’s E Boats were some of the fastest warships in the world. With their low profile, high manoeuvrability and torpedo armament, if they penetrated any Allied convoy, they could destroy several vessels and make their escape before coming under return fire.
