Input: Consider Input: Question: How many years did the war last? Passage:The war ended in May 1945. A couple of weeks earlier had been one of thousands drowned off the coast at Lubeck when a liner/prison ship on which he was being held was sunk by the British. The central part of what remained of Germany (apart from the western part of Berlin) now found itself designated the Soviet occupation zone: political administration and reconstruction would take place under Soviet military administration. Charlotte Bischoff obtained a secretarial position with the Soviet occupation forces in May 1945. She then worked at a succession of jobs with the Free German Trade Union Federation (Freier Deutscher Gewerkschaftsbund, FDGB). The entire Soviet zone would be reformed as the German Democratic Republic, formally founded only in October 1949, but already in April 1946 the contentious merger between the old Communist Party and the Moderate-left SPD created the precondition for a return to one-party rule. Bischoff was one of thousands of former Communists who now lost no time in signing their membership over to the new Socialist Unity Party (SED /) '). Following internal disagreements in the FDGB, in May 1947 Bischoff switched her focus to "Social Help: Greater Berlin" ('), a city-wide welfare organisation with close links to East Germany's SED (party), staying with that organisation till September 1950, after which she went back to working with the FDGB. In 1957 she started work, on a free-lance basis, with the MarxismLeninism Institute of the powerful Party Central Committee. Here she was involved in compiling the official "History of the German Workers' Movement" (). When the volume later appeared she was frequently identified in it but only as the "representative of the Central Committee". Her own contribution to the volume and the collected supporting documents remained unacknowledged during the GDR years. The writer Eva-Maria Siegel thinks this was probably because she included various corrections to the official historical ideology, notably in respect of the contribution of .
