Beginning 2 March 1949, as means of psychological torture, Moczarski was locked up for nine months (or 255 days) with two German SS-men: SS-Untersturmführer of BdS Krakau Gustav Schielke and SS-Gruppenführer Jürgen Stroop. Stroop was responsible for the annihilation of the Warsaw Ghetto after the 1943 uprising. His crimes resulted in the death of over 50,000 people. A committed Nazi, arrogant and unremitting until the very end, he was put on trial on 18 July 1951 for the war crimes committed in Poland and executed on 6 March 1952.
