"Internment"

In the course of the "conscriptions" of the later "recruitments", more than 1,000 Jews were always kept in the collection camps in order to reach the target numbers for the transports. The "collection camps" were consequently always overcrowded, as the converted school buildings were not designed to accommodate so many people. The cramped living conditions resulted in very poor hygienic conditions, which consequently led to diseases and vermin plagues. These circumstances, coupled with the violence of the camp supervisors, led to an increase in suicide attempts, among other things [1]. Reports of people throwing themselves out of the windows of the "collection camps" were not uncommon.
