In the early stages of the Auschwitz camp's operation, the functions of Kapos in Kommandos (work details) and Blockälteste were performed almost exclusively by German criminals. Soon it turned out that there were too few of them (by the end of 1940, only 130 German criminals were brought to the camp), especially to fulfill less important positions: foremen (Vorarbeiter), scribes (Schreiber), room orderlies (Stubendienst), nurses (Pfleger) in the hospital, bath attendants (Bademeister), gatekeepers (Pförtner), and night watchmen (Nachtwache). These positions were filled by those Poles who understood a little German and were dedicated to performing their duties, i.e. beating and abusing their fellow inmates. Later, since there were still not enough German prisoners, some Poles began to take over the more important functions of Blockälteste and Kapos. This usually took place by way of a promotion—each time obviously approved by an SS-man. The outstanding Vorarbeiters were promoted to Kapos, and the previous Stubendiensts to Blockalteste. From 1942, initially in the women's camp, some important functions were also fulfilled by Jewish prisoners.
