    Hello Fernando,

    many thanks for your reply and the wonderful


    Where do you get all these informations?

    Best regards



    As you know on the subject only has two excellent works (Die Deutsche Kriegsmarine 1939-1945 by Walter Lohmann and Hans Hildebrand and German U-Boat Commanders by Rainer Busch and Hans-Joachim R?ll) and them I use are both, however I try to complement with more information from other books (about 150), informations from internet friends, internet sites and with some personal files or official fies

    Cheers, Fernando
