In September 1942, Rumkowski and the Jews of Łódź had realized the fate of the evacuees, because all baggage, clothing, and identification papers of their fellow inmates, were being returned to the ghetto for "processing". The slave workers began to strongly suspect that deportation meant death; even though they had never deduced that the annihilation of Jews was all-encompassing, as was intended. They witnessed the German raid on a children's hospital where all patients were rounded up and put into trucks never to return (some thrown from windows). A new German order demanded that 24,000 Jews be handed over for deportation. A debate raged in the ghetto over who should be given up. Rumkowski sounded more convinced than ever that the only chance for Jewish survival lay in the ability to work productively for the Reich without interference. As Rumkowski believed productivity was necessary for survival, he thought they should give their 13,000 children and their 11,000 elderly. He addressed the parents of Łódź as follows.
