In 1926, the German navy began to send messages that were scrambled in a more random way, making them almost impossible to decipher. Polish codebreakers Antoni Palluth (left) and his cousin Sylwester stand in front of a chart of North African military operations in 1942, when they were working with French intelligence officer Gustave Bertrand in southern France. Palluth set up a business making electronic equipment, including radios the size of a credit card for Polish secret agents. After the 1920 conflict, Ciężki became leader of a radio-intelligence unit. Maksymilian Ciężki and Antoni Palluth were among those signallers. Jamming the Russians’ radio communications bought enough time to secure and save the city. Signallers decoded a telegram from Red Army military commander Joseph Stalin, which indicated that an attack on Warsaw was imminent. Polish skills in cryptography and radio engineering came together during the 1920 Russo-Polish War. Turing unearths a remarkable tale of intellect, bravery and camaraderie that reads like a nail-biting spy novel. Many original Polish papers were destroyed, but the mathematicians’ families have shared personal letters. After the war, military documents were scattered across Europe, and key French records were declassified only in 2016. The Poles shared their secrets with French and British intelligence services before and during the Second World War - the letters X, Y and Z were shorthand for the French, British and Polish codebreaking teams, respectively. In his book X, Y & Z, Dermot Turing, the great mathematician’s nephew, tells the gripping story of a band of Polish mathematicians who figured out much about how German Enigma encoding machines operated, years before Alan Turing did. But as with all breakthroughs, many more people laid the foundations. Bletchley Park, UK - the secret centre where it all happened - rightly gained its place in history. This deluge of knowledge shortened the war. From 1940 onwards, Turing and his team engineered hundreds of electronic machines, dubbed bombes, which decrypted the thousands of missives sent by enemy commanders each day to guide their soldiers. This ability to decipher German military communications is often thought to have helped bring the war to a swifter end, although decades of secrecy delayed the recognition of the work carried out at Bletchley Park.X, Y & Z: The Real Story of How Enigma Was Broken Dermot Turing The History Press (2018)Īlan Turing’s crucial unscrambling of German messages in the Second World War was a tour de force of codebreaking. The information received from deciphered material was codenamed ULTRA, as the fact that messages could be deciphered had to be closely guarded to prevent the encryption methods being changed. ‘Ultra’ secrets were deemed even more valuable than information classified ‘Most secret’, previously the highest security classification used. They could only solve one problem, so were not really true computers. The machines used in the decoding work were called Bombes. The messages sent out each day used a different password, and discovering this password permitted the messages to be read. The Enigma code was eventually cracked by British Intelligence officers working at Bletchley Park near London, initially using methods developed by Polish mathematicians. This naval-type machine is the most advanced Enigma machine used in World War II those used by the other military forces only had three rotors, and two spares. With it comes a rare survival, a smaller case containing five interchangeable spare rotors. It uses four code rotors and is housed in a wooden case. This particular machine was made in 1944. ![]() ![]() Similar machines were first made in the early 20th century, and the first ‘Enigma’ was invented by German engineer Arthur Scherbius in 1918, who sought to sell it for commercial, rather than military, purposes.ĭuring the following years, the Enigma was redesigned and improved several times. The machine is an electro-mechanical device that relies on a series of ‘rotors’ to scramble plaintext messages into incoherent ciphertext.
