Operation Jungle was a programme by the British Secret Intelligence Service (MI6) early in the Cold War from 1949 to 1955 for the clandestine insertion of intelligence and resistance agents into Poland and the Baltic states. The agents were mostly Polish, Estonian, Latvian and Lithuanian exiles who had been trained in the United Kingdom and Sweden and were to link up with the anti-Soviet resistance against the communist governments (the cursed soldiers, the Forest Brothers). The naval operations of the programme were carried out by German crew-members of the German Mine Sweeping Administration under the control of the Royal Navy. The American-sponsored Gehlen Organization also got involved in the draft of agents from Eastern Europe. However, the MGB penetrated the network and captured or turned most of the agents. History In the late 1940s MI6 established a special center in Chelsea, London, to train agents to be sent to the Baltic states. The operation was codenamed "Jungle" and led by Henry Carr, director of the Northern European Department of MI6, and Baltic section head Alexander McKibbin. The Estonian group was led by Alfons Rebane, who had also served as a Waffen-SS Standartenführer during Estonia's occupation by Nazi Germany, the Latvian group led by former Luftwaffe officer Rūdolfs Silarājs and the Lithuanian group led by history professor Stasys Žymantas. The Gehlen Organization, an intelligence agency established by American occupation authorities in West Germany in 1946 and manned by former members of the Wehrmacht's Fremde Heere Ost (Foreign Armies East), also recruited agents from East European émigré organizations for the operations. The agents were transported under the cover of the "British Baltic Fishery Protection Service" (BBFPS), a cover organization launched from British-occupied Germany, using a converted former World War II E-boat. Royal Navy Commander Anthony Courtney had earlier been struck by the potential capabilities of former E-boat hulls, and John Harvey-Jones of the Naval Intelligence Division was put in charge of the project and discovered that the Royal Navy still had two E-boats, P5230 and P5208. They were sent to Portsmouth where one of them was modified to reduce its weight and increase its power. To preserve deniability, a former German E-boat captain, Hans-Helmut Klose, and a German crew from the German Mine Sweeping Administration were recruited to man the E-boat. Agents were inserted into Saaremaa, Estonia, Užava and Ventspils, Latvia, Palanga, Lithuania and Ustka, Poland, typically via Bornholm, Denmark, where the
