Trent Park’s Very Secret War : Bugging the Nazis in WW2

9th October 2019 @ 8:00 am - 8:00 pm

Intelligence agent eavesdropping

During World War Two, British intelligence bugged the conversations of German prisoners-of-war at three stately homes, including Trent Park in north London. 

Thousands of prisoners passed through the clandestine centre at Trent Park from 1939-1942, then from 1942 it was reserved for Hitler’s captured Generals who inadvertently gave away some of Hitler’s most closely guarded secrets, including discussions about V1 (‘doodlebug’), V2 and the atomic bomb programme.

For over 60 years the secret listeners (German-Jewish émigrés who had fled Hitler) never spoke about their work, not even to their families. They died, little knowing that they, alongside Bletchley Park, shortened the war.

Having worked through the declassified files, historian Helen Fry sheds light on one of the little-known, but greatest deceptions of World War Two.
