A BBC magazine report tells the tale of a letter created at Bletchley Park, England's hotbed of cryptanalysts who broke Germany's Enigma codes and were able to plant false information at the highest levels of the Nazi regime. The letter led the Germans to believe that the invasion of Normandy was a ruse intended to distract attention from the main attack point after D-Day, the Pas de Calais. The letter led the Germans to hold troops that might otherwise have joined in the Normandy defense in readiness elsewhere. The ruse was a ruse.
One of the mathematicians who helped break the German codes was a man named Alan Turing, a co-creator of the Bombe machine that allowed the British to crack the German codes. The magazine article does not focus on Turing, but rather on the exploits of Bletchley Park, the ruse letter and the heroism of the intellectuals who helped fight the war from behind a desk.
For those who don't know when World War II was, this is all probably pretty boring. But one comment on the article caught my eye ... something that told a wider story. The comment:
