In the Buchenwald and Niederhagen-Wewelsburg concentration camps, there was an arrivals file card that looked very similar to the Prisoner Registration Card, but it was filled out for report leaders. These cards were not kept in the Political Department but in the registry office of the concentration camp. The prisoner’s reason for arrest could be written by hand or pre-printed, as in the case of Jan de Beaufort, who had been arrested as a “hostage on account of the dishonorable treatment of interned German citizens of the Reich in the outlying possessions of the Netherlands.” On early versions of this card, Buchenwald was still referred to as the Konzentrations-Lager Ettersberg (Ettersberg concentration camp).
