The
executions in Auschwitz I took place in a court between
block 10 and 11 which was divided from the rest of the camp
by two walls. At the back was a black wall. In front of that
wall was scattered sand to suck up the blood of the victims
who had to be naked and barefooted. The bleeing
bodies were taken to the crematorium on a lorry. Puddles of
blood remained on the camp road after the hearse had gone
through.
Shootings did not only take place at the black wall. If a prisoner was not working fast enough, if an SS-guard interpreted a prisoner's glance as rebellious or if an SS-man or officer was bored, prisoners could be shot. If the daily production target was not reached, inmates were shot. Officially, they were all shot "on the run".
