Police Battalion 101 was subordinated to the SS. It was initially given the task of guarding Polish PoWs behind German lines in 1939, then it was deployed in German-occupied areas, specifically the Army Group rear areas and territories under German civilian administration. The police units were given orders to target the civilian population throughout the General Government and were to carry out the expulsion of Poles from the Reichsgau Wartheland under the new Lebensraum policies. These expulsions were known as ‘resettlement actions’. Police Battalion 101 operated in the new Warthegau territory around the cities of Łódź and Poznanń. It was at the Łódź ghetto that the battalion was given duties to police the ghetto. Between June 1942 and November 1943 the battalion was assigned to support the liquidation of the ghetto, which consisted of not only assisting in their transportation to the extermination camps, but murdering them as well in mass shootings. They were also ordered to remove the Jews, with the aid of Trawnikis, from the Lublin, Izbica, Zamosc, Krasnik, Lomazy, Parczew, Miedzyrzec, Radzyn, Lukow, Konskowola, Tomaszow, Serokomla, and Kock ghettos.
