How do I know so many made-up stories about how the Enigma code was cracked and didn't know until yesterday how interesting the real story is? A volunteer at the National Museum of Computing at Bletchley Park just casually blew my mind with a bit of the story. /1 We asked how they came to have an Enigma machine at Bletchley Park, and he said "the Polish postal service intercepted it just before the Germans invaded". No U-Boats, no battles, no heroic Allied Officers - a postman. /2
