One of the major forms of resistance in the Warsaw ghetto was assassination. In late 1942 after the "Great Aktion" when most of the ghetto population was "resettled" to the Treblinka death camp and other camps established by the German Nazis in German-occupied Poland, Jewish underground fighters began targeting Jewish collaborators. They began carrying out death sentences for those Jews who assisted the Nazis in the deception that resulted in fellow Jews going to their deaths. Those Jews went to the Umshlagplatz to board transport trains on the ruse that they were merely being resettled to work camps where life would be better for them.
Resistance and Assassination
No longer could the Jewish Police or Judenrat members act with impunity after the first assassinations in late August, 1942, which sent a shock wave through ghetto and drilled home the message that collaboration that harmed Jews or undermined the Jewish underground would be severely dealt with.
