Product Description

Product Description

Keeping the Atlantic sea-lanes open was a vital factor in the fight against Nazi Germany. In the battle to protect merchant shipping from the menace of surface raiders and U-boats, Allied resolve and resources were tested to the utmost. The story of the extraordinary measures that were taken to combat the threat, at sea and in the air, has often been told. But there is one crucial element in this prolonged campaign that has still not been fully appreciated - the role of code-breaking, in particular the decryption of secret signals transmitted by German Enigma machines. And this is the focus of Roy Nesbit's fascinating new account of the Battle of the Atlantic. Using previously unpublished decrypts of U-boat signals, selected from the National Archives, along with historic wartime photographs, he tells the stories of the individual U-boats and describes their fate. Their terse signals reveal, perhaps move vividly than conventional communications could do, the desperate plight of the U-boatmen as they struggled against increasingly effective Allied countermeasures that eventually overwhelmed them.

4.0 out of 5 stars Ultra versus U-boats, 9 Oct 2009
By Roy Martin (Southampton UK) - See all my reviews
(REAL NAME)   
Well researched and well presented. TNA references with each signal enable further research. Probably more emphasis on aircraft actions than I would have expected in a book with this title. But a most useful addition to my bookshelves.

5.0 out of 5 stars This isn't a novel, 10 Mar 2009
This isn't a novel so if your after an action packed narrative of the war against the U-boats look elsewhere. However if you are looking for a compelling read about the U-boats and how the cracking of the Enigma code helped the allies defeat them, details of the countermeasures and most of all a detailed account of the history of many of the U-boats and the associated engima decripts -then this is for you. High recommended but only for the serious U-boat anoraks.
