Security Police

The Security Police are named in the afterword as among the forces that raided the Secret Annex on August 4, 1944. In the diary’s wider account, their significance lies in the passage from an oppressive system of restrictions and ever-present suspicion to the armed arrest of the people in hiding and two of their helpers.

Identity and Context

The Security Police appear in the account of the Annex primarily through the arrest at 263 Prinsengracht. On the morning of August 4, 1944, between ten and ten-thirty, a car arrived; an SS sergeant, Karl Josef Silberbauer, in uniform, emerged with at least three Dutch members of the Security Police, armed but dressed in civilian clothes. The narration does not identify the Dutch officers by name or describe their individual roles beyond their participation in the raid.

Their arrival was the immediate force behind the arrest, but the diary places that moment within the larger progression of Nazi persecution. After the German occupation, anti-Jewish decrees sharply narrowed Jewish life: Jews had to wear the yellow star, surrender bicycles, observe a curfew, and accept restrictions on transport, shopping, schooling, sport, and entertainment. Such measures made Jewish identity publicly legible and everyday movement increasingly constrained; hiding became one response to a system that restricted freedom before a police raid ever occurred.

The Threat Before the Raid

The family’s move into hiding was planned for July 16, but Margot’s call-up notice forced them to leave ten days earlier. The plan had been prepared over months by moving furniture and clothing out of the apartment. Their destination was the office building where Otto Frank worked, a concealed refuge whose safety depended on secrecy and on the cooperation of a small group of informed helpers.

That concealment remained precarious. A warehouse burglary brought residents to attention: Peter found the warehouse and street doors open, and the group followed strict emergency instructions to stay quiet, avoid water, dress by eight, and not use the bathroom. The break-in ended in theft, including cashboxes, blank checkbooks, and the residents’ entire sugar allotment, but its deeper consequence was to make the vulnerability of the hiding place tangible. Security depended on ordinary doors, the routines of the office, and the hope that intruders would not discover who was concealed upstairs.

Suspicion within the building sharpened the danger. Mr. van Maaren, a warehouse worker described as curious and unreliable, might notice the inconsistent explanations given for the helpers’ movements or the claim that the Annex was in a neighboring building. The diary records precautions around his presence, including an attempt by Mr. Kugler to visit the residents discreetly and a warning from Bep that van Maaren was in the office. The prospect of discovery was therefore not abstract: it threaded through daily work, access to the stairs, and the need to manage what people outside the Annex could see.

The Raid and Arrests

On August 4, 1944, the armed party entered the building. The account says that someone must have tipped them off, but does not establish who did so. That uncertainty is important: the record supplies the fact of the raid and the suspicion of betrayal without resolving the source of the information.

The officers arrested all eight people hiding in the Annex, as well as Victor Kugler and Johannes Kleiman, two of their helpers. Miep Gies and Elisabeth (Bep) Voskuijl were not arrested. The raiders also took all the valuables and cash they could find in the Annex. The distinction between those seized and those left behind marks the raid’s immediate human and material consequences, while the inclusion of helpers makes clear that the risk of concealment extended beyond the people in hiding.

Consequences and Significance

The arrest closed the period of concealment by converting its recurring fears—suspicion, break-ins, cautious movement, and security precautions—into a direct act of state violence. The diary had shown how a small network sustained the Annex: informed office workers and helpers enabled the family to hide, while the residents’ safety depended on discretion and the management of everyday routines. The raid exposed the fragility of that arrangement and brought danger to the people supporting it.

The account also records what followed for Kugler and Kleiman. After their arrest, they were taken to a prison in Amsterdam and, on September 11, transferred without trial to a camp in Amersfoort. Kleiman, because of his poor health, was released on September 18, 1944, and remained in Amsterdam until his death in 1959. These details distinguish the helpers’ subsequent fates from the raid itself and show that arrest did not end with the removal of the residents from the hiding place. In the diary’s narrative, the Security Police are thus associated with the decisive rupture of August 4: the end of the Annex’s hidden daily life and the arrest of both its occupants and those who had helped protect them.
