The Enigma was an enciphering machine used by the Germans to send messages securely. Polish mathematicians, including Marian Rejewski, worked out how to read Enigma messages and shared this information with the British. At the start of the Second World War, the Germans increased its security by changing the cipher system daily. The Allies would have to find a way to break the code.

Drawing upon historians from Poland and the UK, discover how the breaking of the Enigma Code was an unparallelled episode of international cooperation. Its impact can be traced throughout modern history, from the Second World War onwards.

The panel discussion is hosted by the Director of the National Army Museum, Justin Maciejewski.
