It was the Wehrmacht and the Waffen-SS that decided when the evacuation of each section of the city was to start and how soon it must be completed.
The removal of civilians to places remote from The Hague was handled by the Office for the Evacuation of the Civilian Population (BAB), whereas moves within the city and surrounding area were arranged by the Municipal Evacuation Department. The latter employed many members of the NSB and eventually had a staff of four hundred. The evacuations entailed a vast amount of paperwork. The department dealt with housing applications, kept records of people who had found accommodation for themselves, held the keys of vacated properties, sealed rooms used to store furniture, arranged financial compensation etc.
