Format:Paperback
This is an excellent book that focuses on the use of the intelligence they derived from breaking the German encoded signals (mostly from the famous Enigma machine) not how they broke it. Its a very interesting insight to how they distributed this information with the Special Liaison Units and the extreme care they took with their reactions to ensure the Germans didn't guess they were reading their signals. They always tried to provide an alternative means for obtaining the information.
Winterbotham is in an interesting position as he handle the overall operation of distributing this information to the field, strategic decision makers and he regularly briefed Churchill on the information gleaned. It covers some very important events but also has small interesting detail as well such as the fact he often had to stay up late on a Saturday night to brief Churchill after he'd watched his regular Saturday night film.
The book is broken down into the major campaigns of the war across 22 chapters and 190 pages of small print; no pictures. Covering battles in Europe, Africa and Asia. The one area not touched on too much is the Atlantic which was handled separatly by the Navy itself.
The writing style is easy to read and engaging. This doesn't claim to be a history of the war but cover how intelligence (Ultra) is use in the field and strategically, and the level to which it was used. However given how many areas it is used in it does feel pretty comprehensive and put some of the battles in perspective.
I read the 1974 published edition and it does gives a brief account of how the code is broken but from the other books I've read this is not correct. Try The Hut 6 Story for details of what went inside Bletchley Park. But this book does make a great complement to Hut 6 showing the other end of the stick. Its Fascinating to see how much information was being read and distributed and that the Germans never knew. What is also interesting is how people used the information. Patten made maximum use of it, Montgomery less so who seems more to bear it in mind but acts more 'fairly' as if he didn't know in planning his approach. This direct comparison is specifically made in the book.

The best account I have read. Straightforward and identifies the relationship with Churchill as key. Other accounts may be good for the techy but this is for everyone. All should appreciate the work, the importance and the sheer dedication that was required.

Format:Paperback
This book now appears dated, being one of the first books to be written following the de-classification of the Enigma and Ultra wartime secrets in 1974. It shows how the much reported information was distributed amongst the allied command structure and the extreme care taken to protect the secret. Subsequent books have shown some of the 'facts' in this book are perhaps not too accurate however, the book contains a unique perspective on the organisation that ensured the maximum benefit was gained from Ultra without revealing the source. Only 4 stars due to it's dated content and perhaps the need to be reviewed using modern declassified knowledge.

An in-sight view at the Enigma decyphering project
Memories of an RAF official who was deeply involved in the effort for decyphering Enigma-generated cyphertexts. A good book on one of WWII's most exciting facts.
