  • Nacht und Nebel

    On December 7th, 1941 the so-called Nacht und Nebel Decree (Night and Fog) has been issued. Those suspected of resistance in Western Europe were abducted to Germany in widespread covert actions in order to be tried by special courts. The relatives of these prisoners were left in complete uncertainty, which was meant to break the resistance in the respective countries. Prisoners who were not shot immediately without any jurisdiction were transferred to concentration camps as well as prisons on the territory of the "Reich".
