Hi Thorsten, no mention ??. Quote from Gasaway's book 'At the end of Westfjord, could see two cruisers with a screen of three destroyers', then Took his boat to periscope depth and set up firing data as he moved into position' "Fire one and two". Then 'The silence in the conning tower was suddenly broken by two loud explosions'. They conclided that they both had detonated prematurely, which was to plague other U-boats in Narvik. Regards John
