According to Vogt in late 1944 - early ’45 Allied agents were parachuted into Germany as a result of a ‘radio-game’. It seems the organization sending the agents had not realized that their network was under German control. Vogt says that it was probably ‘an American espionage service in London’ (OSS?).
One day three agents were parachuted and immediately taken into custody. These men spoke perfect German and they claimed that they were SS Sturmbannführers and should be released.
Vogt’s superior was Hans Josef Kieffer, commandant at the SD HQ at 84 Avenue Foch in Paris. Kieffer was also SS Sturmbannführer. When the men produced their id cards Kieffer showed them his and pointed out that they were different. This did not faze the captured men. They responded that ‘yours is out of date. All SD identity cards are renewable three-monthly now.’
In order to solve this mystery Kieffer sent Vogt to Berlin to report to his superior Horst Kopkow. When Kopkow saw the identity cards he said: ‘it had been intended to call in the existing ones and to issue new ones in this form’ ‘but none in this form had been issued yet’.
So there you have it! A genuine mystery. Who were these men? Who did they work for? and how did they manage to find out about the new SS id scheme?
