The zone of interest was created on the initiative of the Auschwitz concentration camp commandant Rudolf Höss, who, seeking to find ways of employing prisoners, came to the conclusion that they could be made to work on the farms in the countryside if the current residents were removed. In addition to this, creating such a zone would involve expelling the Polish civilian population from territories adjacent to the camp, which would make it more difficult for prisoners to prepare escapes and maintain contacts with the outside world. There were also plans to create two training villages for “armed farmers”, who were to prepare for the future cultivation and development of land in the German East (this idea never came to fruition). Towards the end of 1940, Höss’s plans were officially approved by Heinrich Himmler.
Preparations to expel the residents of Oświęcim and neighbouring villages were carried out in the first weeks of 1941. In November, German officials accompanied by policemen carried out a census of the local population, and recorded the real estate, chattel and livestock in the villages that were to be evacuated. Next, they marked the houses with red or green crosses. After some time, the inhabitants deduced that the red crosses (on the houses of farmers) meant deportation to the General Government and the green crosses (usually on the houses those employed in the Brzeszcze coal mine or on the railway) meant resettlement in the local area. These crosses were presumably for the orientation of the policemen (or SS-men) who would later carry out the evictions. Also, in the town of Oświęcim, a committee carried out a census, and reviewed apartments with view for German settlement (after the prior eviction of the current residents).
