This is a remarkable book, representing darn good story telling and a triumph of research!
Several popular World War II movies depict the last-ditch effort of the Allies in North Africa, at El Alamein, to stop the advance of seemingly invincible General Rommel and his panzer and infantry units in 1942.
However, while those efforts were truly heroic, the author makes clear that much code-breaking was happening in England, to break the German Enigma codes, in close to real time, with information that ultimately enabling the Allied victory.
Prior to that victory, the Germans had broken the US code, and were able to decode reports of the US military attaché in Egypt, who was well informed about the British mood and troop locations in Egypt and was regularly reporting back to the US. These reports proved invaluable to Rommel and the Germans in key points of Rommel’s advance.
The British knew there was a problem with the American transmissions, since they could look at German reports (and the US reports). The American’s were notified, and after finally deciding to change the codes, incompetence delayed the process. However, right before Rommel’s final push to the Nile, the codes were changed, keeping Rommel unaware of British movement. On the other hand, the British had learned and finally utilized the decoded German information to finally stop Rommel’s advance.
When the British first learned that the German’s were getting information from sources in Cairo, they were not sure if the Germans had broken the code, had stolen code books, or if there was a spy. This took time to determine, and was a mystery on top of the code-breaking efforts.
The battle for El Alamein is an important turning point in the war, both psychologically and militarily (the lost of the middle east oil fields and the use of the Suez Canal would have been devastating to the Allies). It marked a turning point in the war.
This book tells the multi-faceted story of the code-breaking and mystery around the German’s early knowledge of British troops in Egypt. The author had access to many sources in writing this book. He also tracked some of the diplomatic activities. One interesting source was the diary of the Italian foreign minister and Mussolini’s son-in-law, Galeazzo Ciano.
Finally, the writer tells the story in a compelling manner, keeping the reader interested and a bit on the edge of her/his seat.
FB. A fascinating story, darn well told and researched, about a critical event in World War II, that reveals the importance of code-breaking and the dangers of poor security. An important lesson for today’s world of cybersecurity defense and offense.
