Breaking Enigma: remembering the Poles
For decades after the war the contributions of Rejewski and other Polish cipher experts to the Allied victory over Nazi Germany went unrecognised.
But Bletchley Park, the nerve centre of Britain’s wartime code breaking operations, has just held its annual Polish Day – a celebration of the Polish achievements that laid the foundations for British success in cracking German codes. . .
Polish historian Eugenia Maresch says that Alastair Denniston, the first director of Bletchley Park, was inspired by his meeting with the cryptologists at Pyry, the small Polish decoding centre in woods outside Warsaw. There the Poles divulged their methods and Enigma secrets to British and French intelligence.
The Poles were already deciphering Enigma messages in 1933, Mrs Maresch explained, whereas the British did not seriously turn their attention to Enigma until the Spanish Civil War in 1936, when the Axis powers’ aggression started threatening British interests in the Mediterranean.
