How did Bletchley Park break Nazi Germany’s Enigma code?
I’ve read the novel “Enigma” written by Robert Harris [my review here]; I’ve seen the film directed by Michael Apsted [my review here]; and this weekend, I visited Bletchley Park where a British team built on the work of Poles to break the Enigma code used by the German army, navy and air force during the Second World War.
But I still don’t understand how they did it. I mean 159 million million million ways of changing one letter for another. And the Germans changed the settings every day. The analysts were heroes as much as those on the frontline.
