Pre-war When Radó was originally sent to Switzerland, he had been instructed by Soviet military intelligence to build an espionage network, but by 1939, he still wasn't fully prepared.
Sub network Since 1936, a small Soviet cell existed in Switzerland, that had been established by
Maria Josefovna Poliakova in early 1936 and left to German
Ursula Kuczynski to run when Poliakova returned to the Soviet Union in the same year. The network had two principal agents. The first and most important was Polish immigrant
Rachel Dübendorfer who worked as a secretary at the
League of Nations International Labour Organization (ILO). She joined the network in 1934 to obtain information about production at Swiss army factories. The second agent was Swiss lawyer and journalist
Otto Pünter who worked for the anti-fascist news agency
International Socialist Agency (INSA). Pünter ran a clandestine network in Germany which generally supplied economic intelligence. When he'd arrived in Switzerland, Radó had assembled 50 separate sources of intelligence but none matched in quality to that supplied by Pünter. In April 1938, Radó made contact with Pünter who formally joined his network.
Recruitment Through an intermediary,
Léon Nicole who was general secretary of the
Communist Party of Switzerland, Rado was able to formerly recruit several new people into his network. These included
Margrit Bolli who became the third radio operator, who transmitted from her apartment in
Lucerne and
Edmond Hamel (assisted by his wife Olga Hamel), who would become the group's secondary
radio operators. transmitting from their apartment in Geneva. These agents were compartmentalised, i.e. unknown to each other, except when they were man and wife, e.g. Bolli and Hamel and each had a codename which unknown to each other. In his radio communications, Radó used the codename "Dora", which was only known to Moscow Centre. by
Dora about a meeting of leading German
OKW and industry representatives, including
Göring (chair),
Röchling, and
Vögler in , March 1943. Between March and April 1940, Radó was visited by
Anatoly Gurevich in a three-week business trip to Switzerland to deliver $3000 to finance the network along with cipher books necessary to encipher/decipher radio messages during transmission. In August 1940, Radó network was joined by
Alexander Foote, an English Soviet agent in Switzerland who joined
Ursula Kuczynski's network in October 1938. While he was attached to Kuczynski's network, Foote learned how to be a radio operator and by January 1940 was sufficiently competent to reach Moscow Centre. By March 1941, Foote was making regular radio transmissions with Moscow Centre from his apartment in
Lausanne. When Kuczynski left for England in February 1941, Foote was assigned to Radó's network. Foote became the main radio operator for Radó's intelligence network and trained both Bolli and Hamel in radio use for less important radio transmissions. After the war, Foote grossly exaggerated his wartime role by claiming in his book
Handbook for spies, that both he and Radó had separate networks of equal importance, with separate sub-sources. However the traffic report doesn't bear that claim. In May 1941, Dübendorfer and her network were formerly recruited into Radó's network. In October 1941,
Georges Blun was recruited into the network.
Rote Drei In the first half of 1941, a Swiss intelligence officer with the codename "Luiza", gave important information to Pünter (and Radó) that many divisions of the German
Wehrmacht were being concentrated in the East. This warning of an imminent German attack, like that from
Richard Sorge and from other Soviet agents, was dismissed by Stalin. After the outbreak of the
German-Soviet War on 22 June 1941, Radó's network continued to provide Soviet
General Staff with very valuable intelligence on German forces. Some of it was supplied through Pünter by "Salter", whose identity has never been confirmed and by Blun a French intelligence officer who fled to Switzerland after the
capitulation of France. Both had sources in Germany, among them
Ernst Lemmer ("Agnessa"), editor of a German foreign policy bulletin. In March 1942, a most valuable piece of intelligence was sent to Moscow: plans for summer German offensive aimed at the occupation of Caucasian oilfields, known as
Case Blue. The operation was to begin on 31 May and run until 7 June 1942. Radó's network received the intelligence from Blun, provided by General
Adolf Hamann, at the German
OKW. Soviet command did not make proper use of this intelligence.
Lucy network In the summer of 1942, Radó was able to recruit German political emigrant
Rudolf Roessler, through
Christian Schneider, a German lawyer and translator also worked in the ILO, who was friends with Dübendorfer. Roessler, apparently had extraordinary sources in Germany that he collected as part of the
Lucy spy ring. He was able to provide a great quantity of high-quality intelligence, around 12,000 typed pages, sourced from the German High Command of planned operations on the Eastern Front, usually within a day of operational decisions being made. Later in the war, Roessler was able to provide the Soviet Union with intelligence on the
V-1 and
V-2 missiles. On 12 December 1941, the
Abwehr discovered
Leopold Trepper's network in Belgium and gave it the moniker
"Rote Kapelle". On 9 November 1942, Gurevich was arrested and during interrogation he exposed the existence of the Swiss network to the
Abwehr who gave it the name "
Rote Drei". They even obtained the radio
cipher used by Radó's network which enabled them to decrypt some of Radó's radio communications. Meanwhile, Radó's network continued to supply Moscow Centre with valuable intelligence. In April 1943, Stalin received news about the planned
German offensive near Kursk (provided by "Werther", a Roessler source in Germany).
Discovery During the second half of 1943, the Germans persuaded Swiss authorities to act against Radó's network. On 11 September 1943, a Swiss Army radio
counterintelligence company using radio direction-finding equipment notified the Federal Police that radio signals from the Geneva area could be detected, which resulted in the arrest of radio operators Margrit Bolli along with Edmond and Olga Hamel on the night 13 October 1943. Radó went into hiding. On 20 November 1943
Alexander Foote was arrested. On 19 April 1944, Christian Schneider along with Rachel Dübendorfer and her partner Paul Böttcher were arrested which resulted into Roessler's connection to Soviet intelligence being terminated.
Rudolf Roessler was arrested on 19 May 1944.
Escape On 16 September 1944, Radó and his wife Helen left their two children with her brother Hermann Scherchen, in whose home they had hidden, then illegally crossed the Swiss-French border on a French train with the help of the French
Maquis from
Upper Savoy. On 24 September, they reached Paris and settled in a house at 138, rue de Longchamp. At some point in November Radó was ordered to contact Soviet
Red Army intelligence and it was suggested he return to Moscow as soon as possible, to explain what occurred with the Swiss organisation. On 6 January 1945, Radó along with 7 colleagues that included Trepper, Dübendorfer and Foote were evacuated via plane to the Soviet Union. Due to military operations in Germany, a direct flight to the Soviet Union from Paris was impossible, so the plane flew over Northern Africa. Radó suspected his arrest on arrival in the Soviet Union after seeing Foote on the plane. Foote resented Radó's authority and it was likely he was going to expose Radó for financial mismanagement and corruption while working in Geneva. Using a stopover in
Cairo, Radó escaped and managed to enter the British embassy under an alias. He applied for
political asylum, but this was denied and Radó tried to commit suicide, but survived and was hospitalized. He was
extradited by
Egypt to the Soviet Union based on a false accusation, in August 1945 he was brought to Moscow under guard. In December 1946, he was sentenced by a
Special Council of
MGB without trial to 15 years imprisonment on espionage charges. Radó spent the next 10 years in prison including
Lubyanka and Soviet labour camps
Kuchino and at
Ukhta. ==Release==
