In the late 1940s the 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, Baltic section head Alexander McKibbin. The Estonian group was led by Alfons Rebane, who had also served as an 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.[3]

The Gehlen Organization, an intelligence agency established by American occupation authorities in Germany in 1946 and manned by former members of the Wehrmacht's 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.[1][5]

Agents were inserted into Saaremaa, Estonia, Užava and Ventspils, Latvia, Palanga, Lithuania, and Ustka, Poland, all typically via Bornholm, Denmark where the final radio signal was given from London for the boats to enter the territorial waters claimed by the USSR. The boats proceeded to their final destinations, typically several miles offshore, under cover of darkness, and met with shore parties in dinghies. Returning agents were received at some of these rendezvous.


The operation evolved into a number of phases. The first transport of agents occurred in May 1949, with six agents boarding the boat at Kiel. The vessel was manned by Klose and a German crew. The British officers on board, Lieutenant Commanders Harvey-Jones and Shaw, handed over the command of the boat to Swedish officers in Simrishamn, Southern Sweden. The German crew then proceeded via the cover of Öland Island, then east to Palanga, north of Klaipeda, arriving around 10:30pm. Within 300m of shore the six agents disembarked in a rubber dingy and made their way to shore. The boat returned to Gosport, picking up the British officers at Simrishamn and refueling at Borkum.[1]

Following the success of the initial operation, MI6 followed up with several more improvised landings via rubber dingy. Two agents were landed at Ventspils on 1 November 1949; three agents landed south of Ventspils on April 12, 1950 and two agents in December at Polanda.[1]

In late 1950, Hamburg-Finkenwerder. The "British Baltic Fishery Protection Service" was thus invented as a credible cover story given the harassment of West German fishermen by the Soviets. The operation evolved with a secondary task of visual and electronic reconnaissance of the Baltic coast from Saaremaa in Estonia to Rügen in East Germany. For this purpose the boat was re-fitted with additional fuel tanks for extended range and an extensive antenna suite and American equipment for COMINT and ELINT. During this phase, four landings were performed between 1951 and 1952 with 16 agents inserted and five agents retrieved.[1]

In August 1952, a second E-boat was put into service as a refuelling and supply vessel and consort for the SIGINT operations, under the command of Lieutenant E. G. Müller, a former executive officer who served under Klose during World War II. Eight Polish agents were inserted during this period with the use of sea-borne balloons.[1]

During the period 1954-55, three new German-built motorboats replaced the old E-boats. They were christened Silvergull (commanded by H. H. Klose), Stormgull (commanded by E. G . Müller) and Wild Swan (commanded by D. Ehrhardt). They were built at the Lürssen dockyard in Bremen-Vegesack for the West German Border Police, but under the pretense that the boats exceeded the speed allowed by the treaty of Potsdam, French and British authorities confiscated the vessel for Klose's missions. In February 1955, during a SIGINT mission from Brüsterort to Libau, it took place a naval incident with a Soviet patrol boat. Ehrhardt's Wild Swan was fired on by the Soviet vessel, but the German boat slipped away at flank speed after a 15-minute engagement off Klaipeda.[1]

Operation compromised

The operation was severely compromised by Soviet counter-intelligence, primarily through information provided by British double agents. In the extensive counter-operation "Lursen-S" (named for Lürssen, the manufacturer of the E-boats), the NKVD/KGB captured or killed nearly every one of the 42 Baltic agents inserted into the field. Many of them were turned as double agents who infiltrated and significantly weakened the Baltic resistance.

One of the agents sent to Estonia and captured by the KGB, Mart Männik, wrote an autobiography "A Tangled Web. A British Spy in Estonia" which was published after his death and has been translated into English. The book gives an account of his experiences throughout and after the unsuccessful operation.[6]

MI6 suspended the operation in 1955 due to the increasing loss of agents and suspicions that the operation was compromised. The last mission was a landing on Saaremaa in April 1955.[7] While the overall MI6 operation in Courland is regarded as a fiasco, Klose missions are considered successful, as far as the SIGINT and the naval aspects of his incursions are concerned.[1] The motorboats were handed over to the new German Navy in 1956.[1]
