Never before seen decrypted messages between Hitler and his generals before D-Day have been uncovered.

Researchers at the National Museum of Computing, on the famous Bletchley Park estate, have found two years’ worth of Nazi high command messages , revealing confusion among German troops in the days before the allied invasion of Normandy.

The deciphered messages reveal that just weeks before the invasion on June 6, 1944, that the Germans did not know where any imminent invasion would take place.

Nazis even thought it could happen in Scheldt, Belgium or Brest, France.

“These intelligence reports have just come to light this year,” Stephen Fleming from the museum told The Times.

“They have been in public records at the National Archives but nobody has ever looked at them. I said to one of the volunteers at the museum that I would love to see some decrypts of Colossus [the computer that cracked the German codes] because nothing has really come out. They started digging and in February showed me the beginnings of this stuff.”

Bletchley Park is the famous secret British code-breaking centre in Buckinghamshire, used for intercepting top-secret German messages during World War Two.

They were being sent some 2,000 intercepted German radio messages a month, though could only decode around a tenth of those.

Colossus machines were created to decipher the Lorenz code that encrypted messages between Hitler and his generals. The first Colossus was switched on at Bletchley Park on February 5, 1944, just four months before the Normandy invasion which changed the course of the war.

The Lorenz code was considered far more complex than the Enigma code.

Colossus was built and designed by Tommy Flowers, a Post Office engineer.

Some historians believe that Bletchley Park shortened the war by two years.

The decoded German reports showed that troop morale was lowering as Allied air force raids hampered their supply and troop movements.

One of the decoders at Bletchley, Margaret Bullen, 96 said: “I am very proud of what we did. I don’t think I realised the enormity of what we were doing at the time.”

There was also decoded, a Nazi plan to land a spy into the United States using a submarine.
