Prisoner registration forms were created even if prisoners were so weak after a transport that they were unable to speak, or if they were dead on arrival. The Arolsen Archives have preserved such forms for people who had been transported from Auschwitz to Buchenwald or Dachau. In many cases, even their names were not known. Instead, the prisoner clerks would note their prisoner number from Auschwitz, the date of their arrival at the camp and the number that had been assigned to them in Buchenwald or Dachau. Their forms have comments such as vernehmungsunfähig (“unable to be questioned”), unbekannter Toter (“unknown deceased”) or tot eingeliefert von KL Auschwitz (“dead on arrival from Auschwitz concentration camp”).
