Cables in Cipher, the Raoul Wallenberg Case and Swedish-Soviet Diplomatic Communication 1944-1947

In 2011, the Russian government, in order to mark the 100th anniversary of Swedish Diplomat Raoul Wallenberg, decided to allow one Swedish researcher to go through the diplomatic correspondence in cipher between the Soviet Embassy in Stockholm and the Soviet Foreign Ministry during the years 1944-1947. This article presents some of the major findings on Wallenberg and discusses whether parallel paths of Soviet encrypted communication between Moscow and Stockholm may still be harbouring additional information on his case. The ciphers cannot provide us with any conclusive answers on the Soviet motives for arresting Wallenberg, or his ultimate fate. They do, however, provide us with unique insights into how the matter was handled on both the Soviet and Swedish sides.
