It was one of the biggest secrets of the war, the capture of a top
secret Enigma machine from the radio room of the sinking submarine U110.
May
1941 marked the nadir of the Battle of the Atlantic, as Nazi U-boat
attacks were crippling the nation’s ability to survive. And the key to
breaking that threat lay in deciphering the German’s naval Enigma code.
But
while Alan Turing and his colleagues at Bletchley Park worked
tirelessly to crack the code, the working Enigma machine finally
provided them with their breakthrough moment.
This book
sets the story, and the Enigma cryptographers, in context – at the heart
of the Battle of the Atlantic, when it reached its crescendo in the
pursuit of the battleship Bismarck the week after U110 was taken.
