Auschwitz Camp Commandant Rudolf Höss reported that the first time Zyklon B pellets were used on the Jews, many suspected they were to be killed – despite having been deceived into believing they were to be deloused and then returned to the camp. As a result, the Nazis identified and isolated "difficult individuals" who might alert the prisoners, and removed them from the mass – lest they incite revolt among the deceived majority of prisoners en route to the gas chambers. The "difficult" prisoners were led to a site out of view to be killed off discreetly.
