On 20 May 1943, approximately 750 Jews reported to the military police building near Muiderpoort train station in Amsterdam. They complied with a measure taken by Rauter, head of the German SS and the police, that no Jew could stay in Amsterdam without permission. Only Jews carrying a so-called Sperre, a proof of postponement, were allowed to stay on.
They arrived in Westerbork in the evening. At least two of them, a couple, were put on transport five days later to the Sobibor extermination camp, where they were gassed on 28 May 1943. We do not know what happened to the others, because their names are not known.
Rauter was dissatisfied with the low turnout on this day and so, the Germans held a big raid in the centre of Amsterdam a few days later. They arrested around 3,000 people, who were subsequently deported to Westerbork. The Nazis also forced the Jewish Council to take away the Sperre of a large number of Jews and to select them for transport to Westerbork.
