Anne Frank and her Family are Transported to Westerbork Concentration Camp
On the morning of 4 August 1944, the Achterhuis was stormed by the German Security Police (Grüne Polizei) following a tip-off from an informer who was never identified.
Led by Schutzstaffel Oberscharführer Karl Silberbauer of the Sicherheitsdienst, the group included at least three members of the Security Police. The Franks, van Pelses and Pfeffer were taken to the Gestapo headquarters where they were interrogated and held overnight. On 5 August, they were transferred to the Huis van Bewaring (House of Detention), an overcrowded prison on the Weteringschans. Two days later they were transported to Westerbork. Ostensibly a transit camp, by this time more than 100,000 Jews had passed through it. Having been arrested in hiding, they were considered criminals and were sent to the Punishment Barracks for hard labor.
Victor Kugler and Johannes Kleiman were arrested and jailed at the penal camp for enemies of the regime at Amersfoort. Kleiman was released after seven weeks, but Kugler was held in various work camps until the war's end. Miep Gies and Bep Voskuijl were questioned and threatened by the Security Police but were not detained. They returned to the Achterhuis the following day, and found Anne's papers strewn on the floor. They collected them, as well as several family photograph albums, and Gies resolved to return them to Anne after the war. On 7 August 1944, Gies attempted to facilitate the release of the prisoners by confronting Silberbauer and offering him money to intervene, but he refused.
Between July 1942 and September 1944, almost every Tuesday a cargo train left for the concentration camps Auschwitz-Birkenau, Sobibór, Bergen-Belsen and Theresienstadt. In the period from 1942 to 1945, a total of 107,000 people passed through the camp on a total of 93 outgoing trains. Only 5,200 of them survived, most of them in Theresienstadt or Bergen-Belsen, or liberated in Westerbork.
Anne Frank stayed in this hut from August until early September 1944, when she was taken to Auschwitz.
