To have achieved 5 stars, it would have required, in my view:
- a clear map of German naval grid squares: I had to find one on the Internet to be able to see where each Uboat was at the time a message was sent.
- some examples of original messages in German before and after coding, with code books, to compare with the English version and to explain the cyphering/decyphering process.
- better editorial review (for example on P207 and 208, the same message is attributed first to U-212, then to U-821).
Certainly a great research work that is now easily available to all thanks to the author.
Roy C Nesbit is an ex WW2 RAF officer who has a well established reputation as a historian and author - he relates the loss of specific U Boats to decrypts which led to their destruction , this skilfully illustrates the link between fresh intelligence and operational success.
The text reads very well and holds your attention never boring it simply draws you in - this is backed up with the a series of photographs from the national Archives along with clear and concise maps which are illustrate the sinking of the submarines and often the deaths of all or most of their crews.
This is a very good book which brings a lot of new information to the reader when you start it you will want to finish it.
