Breaking German codes real reason for 1942 Dieppe raid: historian

FYI the first capture of a naval Enigma machine and associated cipher keys from a U-boat were made on 9 May 1941 by HMS Bulldog of Britain's Royal Navy, commanded by Captain Joe Baker-Cresswell. The U-boat was U-110. In 1942, the British seized U-559, capturing additional Enigma codebooks. LTC (Join to see)
"The Royal Navy captured German U-boat U-110 on May 9, 1941 in the North Atlantic, recovering an Enigma machine, its cipher keys, and code books that allowed codebreakers to read German signal traffic during World War II.
The Enigma machine was an electro-mechanical rotor cipher machine used by the German navy to encrypt and decrypt messages passing from shore to ships at sea. They considered their codes unbreakable and felt safe in exchanging relatively large volumes of radio messages.
On May 9, British destroyers HMS Bulldog, HMS Broadway, and HMS Aubrietia attacked U-110, embarking on what was later called Operation Primrose. The U-boat was seriously damaged and its crew surrendered when it was thought to be sinking. Fifteen men from the boat were killed and 32 were captured. The capture of the U-110 was successfully kept a secret as the boat sunk the next day. The Germans continued to use their codes, assuming their confidential material sank as well.
The recovered materials were taken to Bletchley Park in England, where cryptographers, including computer pioneer Alan Turing, succeeded in breaking the naval code. The codes allowed the U-boat traffic to be read for several weeks, until the keys ran out. Throughout 1941, the British were able to plot the positions of U-boat patrol lines and route convoys around them. Merchant ship losses dropped by over two-thirds in July 1941, and remained low until November. The codes also allowed the British to become familiar with the messages which helped in breaking the new keys.
The machine used by the German army was decrypted as early as 1932 by Polish cryptographers, who later passed their methodology along to the British and French. Breaking the naval code gave the British an advantage in the Battle of the Atlantic."

It is not surprising that Ian Fleming is drawing attention to himself. The primary reason of the commando raid was to test the German land and underwater defenses and the allied surprise landing capabilities

That man was a legend in his own time.

MAJ Stephen Conway another great post! Thanks for sharing!
