On April 25, Joel Brand, a member of the Relief and Rescue Committee of Budapest, was summoned to a meeting with Adolf Eichmann, who presented him with an offer that would be known as "Blood for Trucks." Eichmann told Brand that the highest SS authorities had approved the terms, in which Eichmann would barter "a million Jews" for goods obtained outside of Hungary, including 10,000 trucks for civilian use, or, as an alternative, for use on the eastern front. The 1 million Jews would have to leave the countryΓÇösince Eichmann had promised that Hungary would be JudenreinΓÇö and might head for any destination other than Palestine, since he had promised the Mufti of Jerusalem that no Jews would be allowed to emigrate there. To negotiate the effectuation of the deal, Eichmann let Brand leave Hungary.
Although Brand was unaware of it at the time, the offer was evidently connected with an attempt by Himmler to drive a wedge between the Western Allies and the Soviet Union, and to conclude a separate peace with the former. Brand did go to Ankara, Jerusalem, and Cairo, and he negotiated with American officials and leaders of the Jewish Agency for Palestine. However, he was arrested and imprisoned in Cairo, and the rescue scheme was never implemented.
