The story of the vital contribution of Polish codebreakers to the cracking of Enigma before World War Two is well known, but what happened to those codebreakers after the invasion of Poland in 1939?


In this episode we follow the long and winding path of the Polish cryptanalysts from Warsaw to London. We also look more widely at the work done by the Polish Government in Exile in the UK to intercept wireless traffic and collaborate with Bletchley Park on signals intelligence.


Head of Content, Erica Munro, is joined by our Research Historian, Dr David Kenyon.


Our thanks go to Dr Ben Thomson for voicing our historical documents.
