I recall reading recently that the bloke in charge of the U-Boats
believed it. I gather he was the only one - the idea I got was that
everyone else in the hierarchy thought he was potty on the subject.

OK, but he had some inside information here - weren't some of the
codebooks used by Turing et al recovered from a captured U-Boat? ;-)

Yes, and even easier: from some of the weather ships
the Germans sent out.

But just having the code books wasn't good enough.
They had to knew the settings in use each day.

IIRC they correlated the encrypted weather reports with the actual reports.


My father was a Met Air Observer flying out of Iceland over the North
Atantic, he was producing the reports that were compared with the enigma
traffic. Probably the youngest person to be cleared into the Ultra secret.
