While negotiations about the first train were continuing, three Jewish Special Operations Executive members from Palestine, Hannah Szenes and two men, Yoel Palgi and Peretz Goldstein, were parachuted into Yugoslavia and attempted to penetrate the Hungarian border. They were caught by the Hungarian underground police. Szenes was taken to prison, interrogated in front of her imprisoned mother, and later killed, while the other two were brought to Kasztner, who convinced the two to go to the German Gestapo and inform them that they are Jewish fighters from Palestine who wish to confirm the 'Blood for Goods' deal, but ask that it reaches Switzerland instead of Palestine.
