Germany was a major target of the Soviet spies, especially after power was seized by the NSDAP party. The Red Orchestra was the name given by German intelligence to the Soviet spy networks operating in Europe during WWII. These networks had been set up in the 1920’s and had managed to infiltrate government departments and business circles of every country in Europe. Through their spying activity they kept Moscow informed of important events in Europe.Their means of communication was the radio and it was this means that led to their downfall. The German Radio Defence agency (Funkabwehr) was able to locate one of the sites used for radio transmissions in 1941 and by apprehending the cipher clerks and their cipher material they were able to read this traffic. By decoding messages they uncovered the names of many Rote Kapelle members and of course these were arrested, interrogated and more people were incriminated. By late 1942 the main networks in Western Europe were destroyed.
However after exposing and dismantling these networks the Germans took measures to continue their transmissions to Moscow, so that they could pass false information to the Soviets and also receive information on new spies sent to the West.
The unit tasked with dismantling the Rote Kapelle networks and handling the radio deception (funkspiel) was the Sonderkommando Rote Kapelle, headed in 1943-44 by Heinz Pannwitz.
Operations Eiffel and MarsIn the period 1943-44 the Sonderkommando Rote Kapelle/ Sonderkommando Pannwitz was based in Paris and handled the radio-games between captured Soviet agents and Moscow. The Germans had managed to capture the leaders of the organization Leopold Trepper (Grand Chef) and Anatoly Gurevich (Petit Chef).
After a short period in captivity Trepper managed to escape but Gurevich was used by the Germans to report disinformation to Moscow and convince them that their spy networks were operating normally.Radio messages were sent from Paris (operation Eiffel) and from Marseille (operation Mars).
The radio network of the French communist partyAnother success of the Sonderkommando Rote Kapelle concerned the undercover radio network of the French communist party. According to a recently declassified CIA report, written by Pannwitz, the French CP had prepared a network of undercover radio stations, ready to be used when the party leadership ordered it.
Using the cover of the Rote Kapelle, the resistance leader Paul Victor Legendre was persuaded to set up this radio network. The Germans managed to build up this organization and inserted their own men as radio operators. By operating this network they got a large number of daily espionage reports and were able to keep track of the resistance and stop acts of sabotage.
According to Pannwitz an added benefit of running this network was that during the Normandy campaign some of the radio stations continued to transmit information, this time on the strength and operations of the Allied forces.
