During the summer of 1936, Schulze-Boysen had become preoccupied by the
Popular Front in Spain and through his position at the Reich Aviation Ministry, had collected detailed information of the support that Germany was providing. The documents were passed to the
Antimilitarist Apparatus or
AM-Apparat (Intelligence organisation) of the
Communist Party of Germany. At the end of 1936,
Libertas Schulze-Boysen and
Walter Küchenmeister, on the advice of
Elisabeth Schumacher—wife of
Kurt Schumacher—sought out
Elfriede Paul, a doctor, who became a core member of the group. The
Spanish Civil War galvanised the inner circle of Schulze-Boysen's group. Kurt Schumacher demanded that action should be taken and a plan that took advantage of Schulze-Boysen's position at the ministry was formed. In February 1937, Schulze-Boysen compiled a short information document about a sabotage enterprise planned in Barcelona by the German
Wehrmacht. It was an action from "Special Staff W", an organisation established by Luftwaffe general
Helmuth Wilberg to study and analyse the tactical lessons learned by the
Legion Condor during the Spanish Civil War. The unit also directed the German relief operations that consisted of volunteers, weapons and ammunition for General
Francisco Franco's
FET y de las JONS. The information that Schulze-Boysen collected included details about German transports, deployment of units and companies involved in the German defence. The group around Schulze-Boysen did not know how to deliver the information to the Soviets, but discovered that Schulze-Boysen's cousin,
Gisela von Pöllnitz, was planning to visit the
Exposition Internationale des Arts et Techniques dans la Vie Moderne that was held in Paris from 25 May to 25 November 1937. Von Pöllnitz fulfilled her mission and placed the letter in the mailbox of the Soviet Embassy on the
Bois de Boulogne. However, the building was being watched by the Gestapo and after posting the letter they arrested her in November 1937. To prepare for the upcoming military
occupation of Czechoslovakia, just after 5 June 1938, a game of planning took place in the Foreign Air Powers Department and shortly afterwards in August a combat exercise took place in the Wildpark-Werder area that is directly southwest of
Potsdam. The Gestapo also prepared for the impending war and, with orders from
Heinrich Himmler, updated their registers of potential enemies of the state. Schulze-Boysen was classified as a former editor of the
Gegner and they were aware of his status. On 20 April 1939, he was promoted to
lieutenant and promptly called upon to perform a study on the comparison of air armaments between France, England and Germany. The overall situation in Germany, which was moving more and more towards the state of war, did not leave the actors associated with Schulze-Boysen idle. In October 1938 Küchenmeister and Schulze-Boysen wrote the leaflet entitled
Der Stoßtrupp (English: "The Shock Troop") for the imminent affiliation of the
Sudetenland. Around 50 copies were
mimeographed and distributed. In the spring of 1939, Paul, the Schumachers and Küchenmeister travelled to Switzerland, ostensibly to treat Küchenmeister's
tuberculosis but also to contact the KPD director
Wolfgang Langhoff to exchange information. In August, Schumacher along with Küchenmeister helped reach Switzerland. He also provided him with information on current German aircraft and tank production, as well as deployment plans for a German submarine base in the
Canary Islands. On his 30th birthday on 2 September 1939, Schulze-Boysen had talked with German industrialist
Hugo Buschmann, with whom he had agreed to receive literature on the
Russian Revolution, Lenin, Stalin, and
Leon Trotsky. Schulze-Boysen was primarily concerned with questions of what alternatives there were to the capitalist system of the Western European countries, and he considered writing his thesis on the Soviet Union during his studies. Schulze-Boysen invalidated the concerns that Buschmann had regarding the literature handover by remarking, "I regularly receive
Pravda and
Izvestia and have to read them because I am a rapporteur on Russian issues. My department requires a thorough study of this literature. Besides, we are allies of Soviet Russia". Schulze-Boysen spent much of 1940 looking for new contacts. Besides his work in the RLM, he studied at the
Deutsche Hochschule für Politik of the
Humboldt University of Berlin for a doctorate. Towards the end of his studies, he led a seminar on foreign studies as an employee of SS Major
Franz Six who was director of the Hochschule. In 1941, Libertas Schulze-Boysen became an English language lecturer to teach translators the language. Schulze-Boysen who also lectured there and met three people at the institute that became important members of his group: student and interpreter
Eva-Maria Buch; confirmed Nazi and
Hitler Youth member
Horst Heilmann and Luftwaffe officer
Herbert Gollnow. Buch translated the resistance magazine
Die Innere Front (English: "The Internal Front" or "The Home Front") into French. Little was known about Gollnow. Heilmann met Schulze-Boysen when he wrote a paper called
The Soviets and Versailles that was presented at a political seminar for the Hitler Youth being attended by Schulze-Boysen. Heilmann was introduced to
Albrecht Haushofer through Schulze-Boysen; it was not the first meeting between Schulze-Boysen and Haushofer but was perhaps the first political one. According to new evidence that was presented in 2010, Schulze-Boysen and Haushofer met at least twice before, understood each other's motives, and allowed a compromise to be reached between them, which enabled Heilmann to turn away from
Nazism. At Schulze-Boysen and Haushofer's first meeting, also attended by
Rainer Hildebrandt whose apartment they were using, they discussed the possibility of cooperation between Germany and the Soviet Union. Haushofer was antipathetic towards the Soviet Union and believed that the only way to establish mutual agreement with Stalin's regime was to confront Soviet power with Europe's right to self-assertion. Schulze-Boysen pleaded for mutual collaboration between the two countries and believed that German communism would emerge as an independent political doctrine, while he anticipated a role for the Soviet Union in Europe. At a second meeting, with trust established between two sides, Haushofer told Schulze-Boysen that an assassination attempt against Hitler was being planned. These two meetings created a level of trust between the two men that reduced their risk of exposure when trying to turn the Wehrmacht officer. In August 1941, after a weekend sailing on the
Großer Wannsee, on Schulze-Boysen's boat, the
Duschika, Schulze-Boysen confided in Heilmann that he was working for the Russians as an agent. Heilmann supplied intelligence to Schulze-Boysen for almost a year.
Schulze-Boysen/Harnack Group In 1941, Schulze-Boysen had access to other resistance groups and began to cooperate with them. The most important of these was a group run by
Arvid Harnack who had known Schulze-Boysen since 1935, but was reintroduced to him sometime in late 1939 or early 1940 through
Greta Kuckhoff. Kuckhoff knew Arvid and
Mildred Harnack when the latter was studying in America at the end of the 1920s, and had brought the poet
Adam Kuckhoff together with the couple. The Kuckhoffs had known the Schulz-Boysens since 1938, having met them at a dinner party hosted by film producer
Herbert Engelsing and his wife Ingeborg Engelsing, a close friend of Libertas and started to engage them socially in late 1939 or early 1940 by bringing Mildred and Libertas together while on holiday in Saxony. Through the Engelsing's, the Schulze-Boysens were introduced to
Maria Terwiel and her future fiance, the dentist
Helmut Himpel. In January 1941, Schulze-Boysen, promoted to lieutenant, was assigned to the attaché group of the 5th department of the Reich Aviation Ministry. His new place of work was in Wildpark in
Potsdam, where the headquarters of the Luftwaffe was located. His job there was to process the incoming reports from the Luftwaffe attachés working in the individual embassies. At the same time, Harnack learned from him that the Reich Aviation Ministry was also involved in preparations for an
invasion of the Soviet Union, and that the Luftwaffe was conducting reconnaissance flights over Soviet territory. On 27 March 1941 in a meeting at the apartment of Arvid Harnack, Schulze-Boysen met the third secretary member of the Soviet embassy,
Alexander Korotkov, who was known to Harnack as Alexander Erdberg. Korotkov was a Soviet intelligence agent who had been operating clandestinely in Europe for much of the 1930s as an employee of the foreign intelligence service of the Soviet
People's Commissariat for State Security (NKGB). Korotkov assigned the code name
Starshina, a Soviet military rank, to Schulze-Boysen as Harnack brought him into the operation. Without being aware of the exact activity of his counterpart at the time, Schulze-Boysen informed him in the conversation that the attack on the Soviet Union had been decided and would take place in the shortest possible time. On 2 April 1941, Schulze-Boysen informed Korotkov that the invasion plans were complete and provided Korotkov with an initial list of bombing targets of railways. On 17 April, Schulze-Boysen reported that the Germans were still indecisive. He stated that German generals in North Africa were hopeful of a victory over Great Britain, but the preparations for the invasion continued. In mid-April, in an attempt to increase the influx of intelligence, the Soviets ordered Korotkov to create a Berlin espionage operation. Harnack was asked to run the operation and the groups were given two radio transmitters. Schulze-Boysen selected
Kurt Schumacher as their radio operator. In the same month, Korotkov began to pressure both groups to break contact with any communist friends and cease any kind of political activity. Schulze-Boysen had a number of friends with links to the
Communist Party of Germany including Küchenmeister with whom he cut contact, but he continued to engage in politics. In May 1941, a suitcase-based radio transmitter was delivered to Harnack via Greta Kuckhoff. Eventually, Libertas was drawn into the espionage operation. As the month progressed, the reports provided to the Soviets became more important, as they in turn devoted more time to ensure the supply of information continued. On 6 June 1941, Schumacher was drafted into the German army and Schulze-Boysen found a replacement radio operator in
Hans Coppi. Schulze-Boysen persuaded Coppi to establish a radio link to the Soviet Union for the resistance organisation. Both Harnack and Coppi were trained by a contact of Korotkov, in how to encode text and transmit it, but Coppi failed to send any messages due to inexperience and technical problems with the radio. Harnack managed to transmit messages but the operation was largely a failure. Around 13 June 1941, Schulze-Boysen prepared a report that gave the final details of the Soviet invasion including details of Hungarian airfields containing German planes. When the
Soviet invasion began on 22 June 1941, the Soviet embassy closed and due to the radio transmitters that had become defective, intelligence from the group failed to reach the Soviet Union. However, they still gathered information and collated it. The couple had read about the
Franz Six murders in the Soviet Union and the group was aware of the capture of millions of Russian soldiers. Schulze-Boysens position in the Luftwaffe gave them a more detailed perspective than most Berliners and by September 1941, they realised that the fate of Russians and Jews had begun to converge. At the same time, the combined group started to collect military intelligence in a careful, systematic manner that could be used to overthrow the Nazis. Members of both groups were convinced that only by the military defeat of the Nazis could Germany be liberated and that by shortening the war, perhaps millions of people could be saved. Only in that way would Germany be able to be saved as an independent state at the centre of Europe. On 18 October 1941, the Soviet agent
Anatoly Gurevich was ordered by
Leopold Trepper, the director of Soviet Intelligence in Europe, to drive to Berlin and find out why the group were no longer transmitting. Trepper received a message on 26 August 1941 with a set of instructions for the Schulze-Boysens, Harnacks and Kuckhoffs to re-establish communications. Although it took several weeks for Gurevich to reach Berlin, the visit was largely a failure and the groups remained independent. Gurevich received intelligence from Schulze-Boysen at a four-hour meeting they held at his apartment.
AGIS leaflets In December 1941 or January 1942 (sources vary), the Schulze-Boysens met psychoanalyst
John Rittmeister and his wife Eva. Rittmeister was happy to hear from the reports that informed him of the German military setback on the
Eastern Front and convinced Schulze-Boysen that the reports should be shared with the German people, which would destroy the myth of German propaganda. However, Rittmeister did not share the activist politics of Schulze-Boysen, nor did he know about his espionage activities. The
AGIS leaflet was created, named in reference to the
Spartan King
Agis IV, who fought against corruption. Rittmeister, Schulze-Boysen,
Heinz Strelow, and Küchenmeister among others wrote them with titles like
The becoming of the Nazi movement,
Call for opposition,
Freedom and violence and
Appeal to All Callings and Organisations to resist the government. On 15 February 1942, Schulze-Boysen led the group to write the six-page pamphlet called
Die Sorge Um Deutschlands Zukunft geht durch das Volk! (English: "The Concern for Germany's Future Goes Through the People!"). Co-authored by Rittmeister, the master copy was arranged by the potter
Cato Bontjes van Beek, a friend of Libertas, and the pamphlet was written up by
Maria Terwiel on her typewriter. One copy survives today. The pamphlet posited the idea of active defeatism, which was a compromise between principled pacifism and practical political resistance. It stated the future for Germany lay in establishing a socialist state that would form alliances with the USSR and progressive forces in Europe. It also offered advice to the individual resistor: "do the opposite of what is asked of you". The group produced hundreds of pamphlets that were spread over Berlin, in phone boxes, and sent to selected addresses. Producing the leaflets required a small army of people and a complex approach to organisation to avoid being discovered.
The Soviet Paradise exhibition In May 1942, the Nazis publicised propaganda as an exhibit known as
The Soviet Paradise. Massive photo panels depicting Russian Slavs as subhuman beasts who lived in squalid conditions and pictures of firing squads shooting young children and others who were hung were shown at the exhibit. Greta Kuckhoff was horrified by the exhibition. The group decided to respond and created a number of
stickers to paste onto walls. On 17 May 1942, Schulze Boysen stood guard on each of the 19 members, travelling over five Berlin neighbourhoods at different times to paste the stickers over the original exhibition posters. The message read: : Permanent Exhibition : The Nazi Paradise : War, Hunger, Lies, Gestapo : How much longer? The Harnacks were dismayed at Schulze-Boysen's actions and decided not to participate in the exploit, believing it to be reckless and unnecessarily dangerous. ==Discovery==
