Enigma: How the Poles Broke the Nazi Code
In 1933, three Polish mathematicians led by Marian Rejewski succeeded in breaking the German Enigma cipher, which the Germans considered unbreakable. In 1939, just before the outbreak of war, the Poles shared their knowledge with French and British intelligence services. This led to the powerful British decoding operation at Bletchley Park, which supplied vital intelligence known as Ultra to the allied forces. Yet, only recently have the Polish codebreakers received international recognition. This text offers a concise, up-to-date history of the Enigma decryption in Poland and the use of this achievement in Poland and England.
