In this memo, the responsible officer in the Wernigerode sub-camp informed the labor assignment leader in Buchenwald that 11 sick prisoners were being transported back to Buchenwald. Prisoners who were “unable to work” were usually taken from the sub-camps back to the main camp. From March 1944, more and more sick prisoners were also taken to Bergen-Belsen. By this point, Bergen-Belsen had become a central “reception” camp and camp for dying prisoners.
