This small-gauge track was one of fifteen leading to five
furnaces consisting of three retorts each. At first small metal trolleys
containing the bodies of gassed victims were pushed by prisoners to the
mouth of each opening. The bodies of these innocent people were then thrust
into the flames. Other, more efficient means of loading the ovens were
soon employed, each team of workers developing its own method. In the upper
portion of this photo is the ceiling, collapsed after the SS, in the face
of the advancing Soviet armies, had dismantled and removed the furnaces
and dynamited the structure in an effort to hide their crimes.
