Hudal used this position to aid the escape of wanted Nazi war criminals, including Franz Stangl, commanding officer of Treblinka; Gustav Wagner, commanding officer of Sobibor; Alois Brunner, responsible for the Drancy internment camp near Paris and in charge of deportations in Slovakia to German concentration camps; Erich Priebke, who was responsible for the Ardeatine Massacre; and Adolf Eichmann—a fact about which he was later unashamedly open. Some of these wanted men were being held in internment camps: generally without identity papers, they would be enrolled in camp registers under false names. Other Nazis hid in Italy and sought Hudal out as his role in assisting escapes became known on the Nazi grapevine.
