🎙️ Episode 47 – The Polish Bombe: The Men Who Broke Enigma First

Everyone knows Bletchley Park. Almost nobody knows this: Enigma was broken seven years earlier, by three young Polish mathematicians working in a locked room in Warsaw — and five weeks before the German invasion, Poland gave the entire secret to Britain and France for nothing.

In Episode 47 of World War 2 in Focus, we tell the greatest untold intelligence story of the war's eve. A bitter German official sells Enigma's manuals for cash. Paris and London call the documents useless — Warsaw doesn't. Marian Rejewski cracks the "unbreakable" machine with pure mathematics, a secret Warsaw workshop builds replica Enigmas, and Poland reads Germany's mail for years while the great powers read nothing. Then, in a forest bunker in July 1939, the Poles hand it all over — and vanish into exile, capture, and fifty years of silence.

Inside this episode:

• Hans-Thilo Schmidt, the traitor whose stolen manuals reached Warsaw after Paris and London shrugged
• Rejewski's 1932 miracle — the permutation theorem later called "the theorem that won the war"
• The bomba and the Zygalski sheets: machines and punched paper hunting the Reich's daily codes
• The Pyry forest meeting — stunned British codebreakers handed replica Enigmas five weeks before war
• The codebreakers' fates: exile, the Pyrenees, Gestapo interrogation, and a clerk's desk in communist Poland until the secret broke in 1973
