Jaeger,

just started Winterbotham´s Ultra (1974) and any information on Ultra was not allowed to be told until spring 1974...

ANyway, like mentioned by you two here the amount of info was huge ( up to 2,000 messages per day ín the book ) so that´s a problem. Also decoding varied in time. And also how to use it and not get the Germans on their toes about it.

One very interesting thing is what you said Jaeger: "not all military commander is acceptable to change his plans by receiving some papers."

At least according to the author some officers even regarded it a crime to use the info against the enemy. especially Winterbotham does not like the Admiralty, as he points in that direction several times in the book.

Interesting book. I´m now reading about year 1941. Gives great insight to the battles and ideas and how much truly was known...Göring could have sent his orders straight to Churchill in Sept 1940 during the Blitz BTW....
