In February 1943, the British government also rejected a plan to pay $3.5 million and just $50 per head to allow 70,000, mostly Romanian, Jews to be protected and evacuated that Weizmann had suggested to the Americans. In May 1944, the British detained Joel Brand, a Jewish activist from Budapest, who wanted to evacuate 1 million Jews from Hungary on 10,000 trucks, with tea, coffee, cocoa, and soap. In July 1944, Weizmann pleaded on Brand's behalf but to no avail. Rezső Kasztner took over the direct negotiations with Adolf Eichmann to release migrants, but they came to nothing. Weizmann also promoted a plan to bomb the death camps, but the British claimed that this was too risky, dangerous and unfeasible, due to technical difficulties. On 20 September 1945, Weizmann presented the first official documents to the British, USA, France, and Soviets, for the restitution of property, and indemnification. He demanded that all heirless Jewish property should be handed over as part of the reparations for the rehabilitation of Nazi victims.
