Enigma wasn't broken by a machine — it was broken by habits

Enigma's plugboard had 150 trillion possible settings — and that security was real. What undid it was not a superior machine but the gap between Enigma's design and the daily habits of the people who operated it. In this video we trace the full mechanism: how Marian Rejewski and the Polish Cipher Bureau broke into the plugboard Enigma around December 1932 using permutation theory and flaws in German operating procedures; how they built working replicas, a 100,000-entry catalogue, and six electromechanical bomby to chase each German procedural upgrade; and how, on 26–27 July 1939 at Pyry, Poland handed the entire toolkit — theory, devices, procedural knowledge — to Britain and France. Gordon Welchman, head of Hut 6 at Bletchley Park, put it on record: without what the Poles shared at Pyry, Hut 6 Ultra would never have got off the ground. The machine didn't lose to a machine. It lost to the distance between its design and its use — and understanding that mechanism changes what the Enigma story is actually about.
