Night and Fog Decree
"Nacht und Nebel" ("Night and Fog") was the codename given to a decree of December 7, 1941, issued by Adolf Hitler and signed by Field Marshal Wilhelm Keitel, Chief of the German Armed Forces High Command. It allowed German authorities to abduct individuals alleged to be "endangering German security" so that they effectively vanished without a trace.
