On July 9, 1941, British mathematician Alan Turing made the first major breakthrough in breaking the German naval Enigma machine (History.com Staff, para. 1).  With the help of cryptographers, cryptologists, and cryptanalysts at Bletchley Park, Buckinghamshire, England, Turing was able to break Enigma using what would come to be known as the 'bombe' (Crypto Museum, para. 1).  Historians estimate that had it not been for Turing and the efforts of those in Hut 8 at Bletchley Park in breaking Enigma, World War II could have lasted for two to four more years, with 14 to 21 million more deaths ensuing (Copeland, P. J. , para. 31). However, imagine the counterfactual scenario in which Turing and his team failed to decode the Enigma messages. How would World War Two, and the world thereafter, been different? In order to better understand the counterfactual, one must understand the factual. Wherefore, an explanation of what exactly breaking Enigma comprised will be detailed.
