“The Abwehr also achieved a great success against the Dutch resistance beginning in March 1942. It called this counter-intelligence coup Operation North Pole, or the Englandspiel. This disaster was almost entirely due to appallingly lax practices in N Section at SOE’s London headquarters. An SOE radio operator was picked up in a sweep in The Hague. The Abwehr forced him to transmit to London. He did so, assuming that, because he had left off the security check at the end of his message, London would know that he had been captured. But to his horror London assumed that he had simply forgotten it, and replied telling him to arrange a drop zone for another agent to be parachuted in. A German reception committee was waiting for the new agent, and he was in turn forced to signal back as instructed. The chain continued, with one agent after another seized on arrival. Each was deeply shocked to find that the Germans knew everything about them, even the colour of the walls in their briefing room back in England. The Abwehr and SD, for once working harmoniously together, thus managed to capture around fifty Dutch officers and agents. Anglo-Dutch relations were severely damaged by this disaster; in fact many people in the Netherlands suspected treachery at the London end. There was no conspiracy, just a terrible combination of incompetence, complacency and ignorance of conditions in occupied Holland.”
