The Germans also enjoyed some noteworthy code breaking successes. Information obtained from such high-level German sources was codenamed ULTRA. In the autumn, the Allies gained advantage in North Africa from deciphering coded messages used by Rommel's Panzer Army.

Although the experts at Bletchley first succeeded in reading German code during the 1940 Norwegian campaign, their work only began to pay off meaningfully in 1941, when they were able to gather evidence of the planned invasion of Greece, and learn Italian naval plans for the Battle of Cape Matapan. The Germans, convinced their Enigma messages were unbreakable, used the machine for battlefield, naval, and diplomatic communications.

In 1939, with German invasion looming, the Poles shared their information with the British, who in turn established the Government Code and Cipher School at Bletchley Park in Buckinghamshire. Close links between the German and Polish engineering industries allowed the Polish Cipher Bureau to reconstruct an Enigma machine and read the Wehrmacht's messages between 19. The first people who came close to cracking the Enigma code were the Polish. German code experts added new plugs, circuits and features to the machine during the pre-war years, but its basic principle remained the same. To decode the message, the recipient needed to know the exact settings of the wheels. The Enigma machine enabled its operator to type a message, then 'scramble' it using a letter substitution system, generated by variable rotors and an electric circuit. The Enigma story began in the 1920s, when the German military - using an 'Enigma' machine developed for the business market – began to communicate in unintelligible coded messages. However, the meticulous work of code breakers based at Britain's Bletchley Park cracked the secrets of German wartime communication, and played a crucial role in the final defeat of Germany.

It was thanks to ULTRA that we won the war.ĭuring World War II, Germany believed that its secret codes for radio messages were indecipherable to the Allies.
