It first seemed to be a simple, if fantastic, deal: Blut gegen Waren, Jewish blood in exchange for goods. On 18 May 1944 two emissaries flew into Intanbul on special missions for high Nazi authorities. The first, Joel Brand of the Jewish Rescue Committee in Budapest, explained that he came with a proposal from Adolf Eichmann. If the Allies provided Nazi Germany with ten thousand trucks for use exclusively on the eastern front, as well as large quantities of tea, coffee, cocoa, soap, and assorted war materiel, Eichmann and Germany would spare the lives of approximately eight hundred thousand Jews then in German-occupied Hungary. But Brand's travel companion, Andrea Gyorgy (alias Bandi Grosz), a Jewish convert to Catholicism and a smuggler as well as agent for several intelligence services, claimed that he had a separate and more complicated mission: to contact Allied authorities and initiate peace negotiations between Nazi Germany and the West at the expense of the Soviet Union. After brief discussions with Jewish officials in Istanbul, Brand and Gyorgy separately crossed the border into British-held Syria, trying to reach Palestine. Suspicious of both men and both offers, British officials arrested them and sent them to intelligence headquarters in Cairo for extensive interrogation, which kept them out of action.
