Mark IV Radio

Artifact Details

Sussex teams transmitted critical intelligence to London about German troop movements and targets for Allied bombers.

In 1942, Rene Joyeuse escaped from France and joined the Free French Forces, eventually serving with OSS.  Sent to London for training, he parachuted back into France where he used this radio as part of the Operation Sussex intelligence team in 1944.  He received the French Legion of Honor and the American Distinguished Service Cross for his service.
