The most
efficient method to kill people was gassing them. Therefore,
the SS used the hydro-cyanic acid compound "Cyclone B" which
evaporated at body temperature in a hermetically sealed room
and led to death from suffocation within a very short
time.
First attempts to kill with gas took place in September 1941 in the arrest cells of block 11 at Auschwitz I, the main camp. Then, the mortuary at crematory I was used as gas chamber. For lack of secrecy and the limited efficiency of crematory I, the SS went to Birkenau and reconstructed two farmhouses in the wood into gas chambers. The bodies were brought over narrow-gage railway tracks to pits, some hundred metres of distance, where they were first buried, but dug out again in the fall of 1942 and burnt.
Since also
the provisional plants were not sufficient, the construction
of the four big crematories started in July 1942 which were
put into operation between March and June 1943. These
extermination plants had to be built by prisoners
themselves. Within
those crematories, all stations of the extermination process
were geographically centralized and mechanized. Each station
had undress rooms, gas chambers and ovens to incinerate the
bodies.

According
to technical calculations, 4.756 bodies could be burnt in
the crematories. But this was just a theoretical factor,
which inluded the time for maintenance and purge of the
fire-places. Practically, up to 5.000 bodies were burnt in
the crematories II and III every day, 3.000 in crematorium
IV and V. The capacities of the funeral piles at the bunkers
was unlimited. In summer of 1944, during the deportation of
Hungarian Jews, the SS put bunker II into operation again.
At this time, up to 24.000 people could be killed and
burnt.
The ashes of the dead were used as fertilizer on the surrounding fields, to dry swamps or they were just scattered out into rivers and lakes around the camp.
