After returning from Moscow in 1931 following his studies at the International Lenin School, he became the leader of the KJVD in the Saar region. After the Nazi seizure of power in 1933, Communist activities within Germany were only possible undercover; the Saar region however still remained outside the German Reich under a League of Nations mandate. Honecker was arrested in Essen, Germany but soon released. Following this he fled to the Netherlands and from there oversaw KJVD's activities in Pfalz, Hesse and Baden-Württemberg. Honecker returned to the Saar in 1934 and worked alongside Johannes Hoffmann on the campaign against the region's re-incorporation into Germany. A referendum on the area's future in January 1935 however saw 90.73% vote in favour of reunifying with Germany. Like 4,000 to 8,000 others, Honecker then fled the region, initially relocating to Paris. On 28 August 1935 he illegally travelled to Berlin under the alias "Marten Tjaden", with a printing press in his luggage. From there he worked closely together with KPD official Herbert Wehner in opposition/resistance to the Nazi state. On 4 December 1935 Honecker was detained by the Gestapo and until 1937 remanded in Berlin's Moabit detention centre. On 3 July 1937 he was sentenced to ten years imprisonment for the "preparation of high treason alongside the severe falsification of documents". Honecker spent the majority of his incarceration in the Brandenburg-Görden Prison, where he also carried out tasks as a handyman. In early 1945 he was moved to the Barnimstraße Women's Prison in Berlin due to good behaviour and to be put to work repairing the bomb-damaged building, as he was a skilled roofer. During an Allied bombing raid on 6 March 1945 he managed to escape and hid himself at the apartment of Lotte Grund, a female prison guard. After several days she persuaded him to turn himself in and his escape was then covered up by the guard. Honecker spent most of his time in prison under solitary confinement. After the liberation of the prisons by advancing Soviet troops on 27 April 1945, Honecker remained in Berlin. His "escape" from prison and his relationships during his captivity later led to him experiencing difficulties within the Socialist Unity Party, as well as straining his relations with his former inmates. In later interviews and in his personal memoirs, Honecker falsified many of the details of his life during this period. Material from the
