    One thought on “The Ultra Secret”

    1. This is an interesting book, although the title is a bit misleading. Those who are expecting a detailed account of the Bletchley Park scene, or details about how the codes worked and how they were broken -- will be disappointed. Those hoping for details on the moral implications and decisions made by having to allow certain attacks to happen, to avoid tipping off the Nazis that the Allies had broken their code -- will also be disappointed. What we have instead is a detailed operational account o [...]

    2. I originally bought this hoping to learn about the workings of Bletchly Park and the cryptographic activity that went on there. As it turns out this is not the book for that particular story, but nonetheless I'm very glad to have read this. The Ultra Secret concentrates rather on the story of how the intelligence gained from the Enigma (and other) code-breaking was used in the Allied conduct of the second World War and how this information was securely distributed to those who needed it; all tol [...]

    3. I first read this book back in 1975, when it first came out. After seeing The Imitation Game I dug it out from the basement bookshelves for another quick read.Back in 1975, the book caused quite a stir, being the first report that the allies in WWII had actually broken the German codes and were frequently able to know exactly what the German plans and order of battle were. Elsewhere on the net one can find now-declassified reviews from inside NSA where apparently quite a few people got their kni [...]

    4. During WWII, Ultra was the code name for the Allied intelligence derived from breaking the German Enigma cipher. Published in 1974, this was one of the first public accounts of Ultra. There are almost no cryptographic details in this book; it is a personal recollection of a man's role in preserving the operational secrecy for the "secret" itself. It describes a network of special liaison units (SLU's) and training visits to the principal receivers of the intelligence: Churchill, Eisenhower and t [...]

    5. Read the other reviews. As a person too young to understand the war while it was going on, the impressions I got after the war changed after reading The Ultra Secret. America's forces and our allies were greatly aided by having the machine code breaker called the 'Enigma' machine.I was told about this book by a woman friend who worked on the project as one of the early women who enlisted at the time and who kept silent about it for the 30 years that all who worked on it were required to maintain [...]

    6. I thought I would not like this because I am not really into military history at all- I only like the spy stuff! But this narrative by the man who organized and shepherded the Ultra messages (decodings of Nazi secret ciphers from the Enigma machine)was very interesting. That said, it is mostly a revelation about the role of Ultra in the battles of World War II, with a definite focus on the European theater.

    7. First-person perspective of the war as a whole, with some developed perspective of the war as a whole and an under-lying timeline of German forces movements as decoded from Enigma. Also describes the complexities of the code-breaking process, but more in a "we're talking over drinks" rather than diving into advanced theories.

    8. I had no idea until about a year ago that we had access to many of Hitler's communications during the war. How cool was that?!?This book was written by a guy who was directly involved in reviewing the communications they recovered from Ultra.

    9. very interesting--and so grateful to the many who made this information a vital piece in winning the war against Hitler and the Nazis. We need to not forget.

    10. The book is more personal reminiscence than full study, but it's a decent quick overview of the importance that code breaking had for the Allied effort in the Second World War, particularly against Germany. It made quite a splash when it came out in 1974 because it was the first public revelation of the ability to read messages coded through the Germans' Enigma machines. The pioneering status and Winterbotham's lack of access to official files that were still secret at the time excuse most of th [...]

    11. I was excited about reading this, since the author was a spy who actually got close to Hitler and learned secrets for the Allies. This was published in 1974, so the recollections were fresh. However, it's not for the uninitiated. There's many references that I did not understand, and some notes at the bottom of the page would have made it a far better read. Without knowledge of many of the references, I felt left out of the book. Granted, I could have Googled many of the references, but then it [...]

    12. As has been said in many of the reviews here, this is not a book about the Enigma code-breaking. Also, with regard to ‘errors’ referred to here, Winterbotham does point out clearly—in the edition I read at least—that he is telling the story as he knew it at the time.I borrowed this book from my local library because I thought it would add to the story of Bletchley Park (a place I think I would have enjoyed working in, had I been around at the time). The book does add to that story in som [...]

    13. This book was written by the British officer who was in charge of disseminating the information gathered via the intercepted German and Japanese secret war messages. The reading of which was made possible by the the code breakers at Bletchley Circle solving the riddle of the Enigma Machine. The author doesn't tell about any battles in a blow-by-blow way. His focus is the detailed information gathered; who it did, or did not, get passed on to; how it effected the outcome of battles; and the extre [...]

    14. There is not much excitement to this book, a straightforward account of how the breaking of the German code greatly influenced the outcome of World War 2. In essence, the Allies often knew what the Axis armies were going to do before the Axis commanders. Published in 1974, this was the first book that revealed the Allies' secret weapon.

    15. The English spy organization that became know as Ultra, had broken the code of Germany's Enigma machine. This book tells the story of how British Intelligence used this information to win WWII without ever allowing the Germans to know the code was broken. This is an interesting, fast paced account of the role Ultra played in defeating the Germans.

    16. Fascinating first look into one of the best kept secrets from WWII. Published in the early 70s, this was a huge revelation to the general public and provided great insight into how the Allies were able to prosecute the war successfully.

    17. It would be better read as a companion to another history of the war. Hard for me to remember all the background history where the author assumes his average history buff reader in the 1970s would remember this from reading if not personal remembrance of the war itself.

    18. A helpful book written by one of the best sources, but I found it a bit too technical. For pure science/technology, I'd give it five stars.
