Pyry Forest Meeting - 75th Anniversary

July 2014

On 26 and 27 July 1939 one of the most important events in the history of intelligence took place in the woods outside Warsaw. Just three weeks before the Government Code and Cypher School (GC&CS) moved to its War Station at Bletchley Park, its Head, Alastair Denniston, and its Chief Cryptanalyst, Dilly Knox, travelled to Warsaw to meet their Polish and French equivalents to share all they knew about Enigma.

At a commemorative ceremony in Warsaw held earlier this month, BBC Security Correspondent, Gordon Corera spoke to the GCHQ Departmental Historian, on BBC Radio 4’s Today Programme.

Many thanks to the BBC for letting us share this interview.
