But the camp itself, this was really and truly the death factory.
Birkenau had four crematorias, two gas chambers, two, two
crematorias on one side of the road, two gas chambers, two
crematorias on the other side of the road. And the railroad
tracks went right into, close to the crematoria. And the whole
camp could see. You could see the flames--not just the smoke--you
could see the flames from the chimney. And, well, of course, when
they were burning the Muselmaenner, the people that were
skeletons, only the smoke. But when there were fat people, with
still fat on them, there were flames.
