This is similar to the cars that transported people to the various camps. People (children, senior citizens)
were crammed into the cars (standing room only). The train transport often took days and the people were exposed to extreme cold or
extreme heat. There were NO washroom facilities. Many did not survive the journey.
This is what remains of the crematoriums and gas chambers. The Nazis destroyed 95% of the evidence. We know that
this is the site of the gas chambers and crematoriums because at the end of the war, the Nazis forced many victims to
march back to Germany. There were some prisoners who were too weak to march and the SS guards thought that they
would just die. However, many in fact did survive and explained what happened. Auschwitz-Birkenau was
liberated by the Russian Red Army in late January, 1945.
