How One British Mathematician Used A Single Letter Flaw To Crack 100 Nazi Enigma Cipher

One tiny flaw buried inside the most feared cipher machine of World War Two changed the course of the war at sea. Alan Turing noticed that no letter on the Enigma machine could ever encrypt as itself — and from that single mathematical impossibility, he built the key that cracked a code the Third Reich believed was unbreakable. Inside the freezing wooden huts of Bletchley Park, thousands worked in total secrecy to read German U-boat orders in near real time, rerouting Allied convoys and quietly turning the tide of the Battle of the Atlantic. This is the story of how one letter saved thousands of lives. #BletchleyPark #AlanTuring #EnigmaCode #WW2History #BattleOfTheAtlantic #CodeBreakers #worldwartwo
