Upon controlling Poland, the German Nazis arrested, imprisoned, and killed approximately 61,000 people as enemies of the German Reich, all of whom were identified as the intelligentsia of each city, town, and village. Each man and woman was biographically listed in the Special Prosecution Book-Poland (Sonderfahndungsbuch Polen), which German citizens of Poland loyal to the Nazi party in the German Reich compiled before the war for the German police and security forces of the SiPo (Security Police) and the SD (Security Service).
