The World War II ended in May 1945 , but the previous month Brunolf Baade had been arrested by an advance party of US soldiers that had surprised him at the outsourced Junkers design office at Raguhn . Baade had been a member of the German Nazi Party since 1937 and was held prisoner by the Americans in Bad Hersfeld for a couple of months . With his gifts for easy friendship and fluent English he was able to engage his captors in conversation . Baade would later recall emphatic assurances received at this time from US officers that Germany would be radically de-industrialised and certainly not permitted an aircraft industry for many decades . It was , he said , this that persuaded him to support a German future determined by the Soviet Union . Between April and June the Americans occupied Dessau : they comprehensively looted the Junkers library and technical documents , along with the latest aircraft and engines which their soldiers removed apparently as trophies . The Americans released Baade in June 1945 and early in July American forces were replaced in central Germany by Soviet troops , respecting the division of Germany into occupation zones , already agreed between the allies at the Yalta Conference . Dessau was now in the Soviet occupation zone
