Erik Hazelhoff Roelfzema - Secret Agent

Secret Agent

In London, Hazelhoff Roelfzema, with the help of general François van 't Sant, director of the Dutch CID (Central Intelligence Service) and Col. Euan Rabagliatti (Secret Intelligence Service) set up a secret service group known as the Mews, after Chester Square Mews where they lived in London. The goal was to establish a contact with the Resistance in the Netherlands. Several agents were parachuted, others were put ashore at the beaches of Noordwijk and Scheveningen. Roelfzema did not receive much cooperation from the Dutch government, and Van 't Sant was forced to transfer control over the CID to Colonel Mattheus de Bruyne of the Dutch Marine Corps.

De Bruyne did not do a good job. He failed to recognize the fact that his agents were arrested and continued to broadcast messages – for the Germans. The usual procedure for transmitting messages was to include small errors. If an agent was forced to work for the Germans, he would leave out the errors. The result should be that contact was aborted immediately. De Bruyne, however, concluded that the agents simply forgot to use the security-checks and even sent messages to remind them. Other intelligence blunders were the maps he had attached to the wall in his London office, showing the landing sites of Noordwijk, Scheveningen and Walcheren in full detail.

Hazelhoff Roelfzema and De Bruyne did not get on. De Bruyne threatened to court-martial for ignoring an order – at the same time Hazelhoff Roelfzema was proposed for the Willemsorde (the highest military decoration in the Netherlands). He was awarded the Willemsorde (Knight, 4th class) in 1942: the court-martial was cancelled after a meeting with Dutch Navy minister Furstner.

The 1979 history of the Special Operations Executive network in the Netherlands by M.R.D. Foot has confirmed the degree of German penetration of SOE's Dutch networks, something SOE denied during the War. The British intelligence effort in the Netherlands was penetrated throughout the war, from the capture of two SIS agents, Captain Sigismund Payne Best and Major Richard Stevens in the Venlo Incident in November 1939, to the capture of some 50 British and Dutch agents by the Abwehr and the Sicherheitsdienst in Operation North Pole.
