Happy Germans

Warsaw Ghetto.  SS SIPO Security Police interrogate Jews rounded up in the operation.  The commander of this operation, SS-Gruppenfuhrer and High Commander of SS and Police, Jurgen Stroops, for Warsaw, compiled a detailed photographic report of the operation, including a carefully detailed inventory of the SS, Waffen-SS, Gestapo, Polizei and Heer units employed by him over the periods of the operation.  Down to which days they were employed.  Stroop was captured by the Allies in an SS mental hospital; the SS doctors considered him "instable" as regards his mental health.  He was tried, sentenced to death and executed.  Best regards, JR.

Warsaw Ghetto.
