The U-boat was one of Germany's most potent sea weapons during the First and Second World Wars. During World War I, several thousand ships were sunk by u-boats alone. U-20 was an early U-boat, as it was only the beginning of the war. U-20 was commanded by Kapitan-Leutnant Schwieger. Schwieger had G type torpedoes, which were extremely unreliable (Schwieger did not even expect the torpedo to sink the ship--only to see what damage it did). He was therefore stunned to watch the ship go down in 18 minutes.
