Hi JayDee,
could you please tell me the titles of your books? I'm always looking for good books about u-boats (operations and technical data) and I'm wondering whether you can recommend some books I don't know yet. Thanks!
Regards, LGN1
PS: The VIIC handbook mentions 10 oxygen bottles with 50ltr and 150atü. Unfortunately, this data does not help us much because we don't know accurately the volume of the boats and the oxygen consumption of the crew
@Stiebler: I meant the 1940 Norway campaign (Weserübung).
