| Footnote : | In the first phase of the war there were many hits against enemy vessels reported, when the torpedoes in reality were running deep or the magnetic pistol was misfiring. Such detonations were later called "Frühzünder" (early detonations). During submerged attacks only acoustic information was obtainable, so when there was a detonation at about the correct running time, the U-Boats considered them to be hits. |
