Bachelor’s Hall in Hundon, Suffolk was the first headquarters of the Special Duties Section or SDS. The top secret communication network set up to allow SDS members to report on German troop movement if we had been invaded.
The report is based primarily on information supplied by Capt Ken Ward (Royal Corps of Signals), the leader of the original TRD design team (interview 10 August 1999) and it can be read here.
