Professor Copeland has compiled an excellent book telling the story in both human and technical terms of the building of Colossus and of the extraordinary efforts which resulted in the breaking of the Lorenz cipher, known as Tunny. It is an exciting story, The Germmans thought they had an unbreakable cipher and used it for the highest level communications, including those from Hitler himself to his commanders in the field. Some of the chapters may be a little too technicla for the average reader, but there is plenty of material that needs no technical knowledge to understand. The book is well illustrated and tells clearly how the world's first programmable computer was built. This story could not be toild earlier as there was a complete embargo preventing any of the peoople involved in any way from talking about it - even to their spouses. As one of the survivors of the team in the "Testery" which was able to break the German Tunny traffic on a daily basis so that top secret German infomartion could be passed to the allied commanders, I am grateful to Professor Copeland for compiling this excellent book. With the help of a number of contributors who were directly involved he tells the story well and it is an excciting story. The books is well illustrated with both photographs and diagrams. This story reaklly eeded to be told. Thhe geniuses whose work it describes have never been properly recognized. I am delighted that Professor Copeland has done something to right this situation I recommend the book highly.

I found the overall story compelling. However, the focus of the book was mostly on technical details and the personalities involved. While both were interesting, I was hoping to hear how the allies were able to make use of the information gleaned from the various encryption systems they were able to exploit.
