Which technological innovation was crucial for the Allies’ victory in intelligence?

The decryption of the Enigma machine

The decryption of the Enigma machine, carried out by a team of British cryptanalysts led by Alan Turing at Bletchley Park, was one of the most critical turning points in World War II in terms of intelligence. Thanks to their hard work and the invention of machines like the cryptographic Bomb, they managed to break the secret of German encrypted communications. This achievement gave the Allies a decisive advantage on the battlefields by anticipating many strategies and movements of the Axis forces. By providing vital information on enemy operations, the decryption of Enigma directly contributed to key Allied victories, including the Battle of the Atlantic, thereby saving countless lives and accelerating the end of the war. This technical feat not only proved crucial for military success but also laid the foundations for modern cryptography and computer security, profoundly influencing post-war technological development.
