There were three camps - Auschwitz I, Auschwitz II (Birkenau) and Auschwitz III (Manowitz - Buna).
Auschwitz II (Birkenau) was "Vernichtungslager." (extermination camp) Standard Oil's syntetic rubber factory was located in Auschwitz III (Buna)
Auschwitz III was a work camp on paper but NO inmates got out of there alive. They were starved and worked to death. Buna was a death camp, just like Birkenau, only the method was different. Inmates were not fed at all, only given some chemical concoction called "Buna soup" that allowed body to metabolyze their own body fat and proteins at fast rate. In a week, they would get speciffic look and would die soon afterwards. A starving human could survive for 40 days. None of them survived that long.
This savagery is among the most inhuman among the numeorous Nazi atrocities, yet, it is rather little known.
Saying that Allies did not bomb Buna because of "the prisoners" is rather cynical.
The point I wanted to make:
-civilians of German cities were bombed, yet it did not change Nazi resolve to fight till the Ruskies came to Berlin
-Nazi industrial output was mostly unaffected by aerial bombardment(according to McNamara).
All this at horrible 50% casualty toll on USAAF.
Yet, the railway infrastructure leading to extermination camps was not destroyed and extermination camps worked till the Nazi bitter end.
Okay point taken but Standard Oil synthetic rubber????
