Sites included Bronna Góra, Ponary and others.

Prisoners represented about a quarter of the total workforce of the Reich, with mortality rates exceeding 75 percent due to starvation, disease, exhaustion, executions, and physical brutality.

Heinrich Himmler visited the outskirts of Minsk in 1941 to witness a mass shooting.

, revealed that psychologically "unable to endure wading through blood any longer", many the killerseither went mad or killed themselves. The Nazis had first used gassing with carbon monoxide cylinders to murder 70,000 disabled people in Germany in what they called a 'euthanasia programme' to disguise that mass murder was taking place. Despite the lethal effects of carbon monoxide, this was seen as unsuitable for use in the East due to the cost of transporting the carbon monoxide in cylinders. Each extermination camp operated differently, yet each had designs for quick and efficient industrialized killing. While Höss was away on an official journey in late August 1941 his deputy,

pellets were used on the Jews, many suspected they were to be killeddespite having been deceived into believing they were to be deloused and then returned to the camp. As a result, the Nazis identified and isolated "difficult individuals" who might alert the prisoners, and removed them from the masslest they incite revolt among the deceived majority of prisoners en route to the gas chambers. The "difficult" prisoners were led to a site out of view to be killed off discreetly. A prisoner unit (Special Detachment) assisted in the process of extermination; they encouraged the Jews to undress without a hint of what was about to happen. They accompanied them into the gas chambers outfitted to appear as shower rooms (with nonworking water nozzles, and tile walls); and remained with the victims until just before the chamber door closed. To psychologically maintain the "calming effect" of the delousing deception, an SS man stood at the door until the end. The talked to the victims about life in the camp to pacify the suspicious ones, and hurried them inside; to that effect, they also assisted the aged and the very young in undressing. To further persuade the prisoners that nothing harmful was happening, the deceived them with small talk about friends or relations who had arrived in earlier transports. Many young mothers hid their infants beneath their piled clothes fearing that the delousing "disinfectant" might harm them. Camp Commandant Höss reported that the "men of the Special Detachment were particularly on the look-out for this", and encouraged the women to take their children into the "shower room". Likewise, the comforted older children who might cry "because of the strangeness of being undressed in this fashion". Yet, not every prisoner was deceived by such psychological tactics; Commandant Höss spoke of Jews "who either guessed, or knew, what awaited them, nevertheless ...

found the courage to joke with the children, to encourage them, despite the mortal terror visible in their own eyes". Some women would suddenly "give the most terrible shrieks while undressing, or tear their hair, or scream like maniacs"; the immediately took them away for execution by shooting. In such circumstances, others, meaning to save themselves at the gas chamber's threshold, betrayed the identities and "revealed the addresses of those members of their race still in hiding". Once the door of the filled gas chamber was sealed, pellets of Zyklon B were dropped through special holes in the roof. Regulations required that the Camp Commandant supervise the preparations, the gassing (through a peephole), and the aftermath looting of the corpses. Commandant Höss reported that the gassed victims "showed no signs of convulsion"; the Auschwitz camp physicians attributed that to the "paralyzing effect on the lungs" of the Zyklon B gas, which killed ''before'' the victim began suffering convulsions. The corpses were additionally found half-squatting, their skin discolored pink with red and green spots, with some foaming at the mouth or bleeding from their ears, exacerbated by the crowding in gas chambers.

The was responsible for burning the corpses in the pits, stoking the fires, draining surplus body fat and turning over the "mountain of burning corpses ... so that the draft might fan the flames", wrote Commandant Höss in his memoir while in the Polish custody. He was impressed by the diligence of prisoners from the so-called Special Detachment who carried out their duties despite their being well aware that they, too, would meet exactly the same fate in the end. At the Lazaret killing station they held the sick so they would never see the gun while being shot. They did it "in such a matter-of-course manner that they might, themselves, have been the exterminators", wrote Höss. He further said that the men ate and smoked "even when engaged in the grisly job of burning corpses which had been lying for some time in mass graves." They occasionally encountered the corpse of a relative, or saw them entering the gas chambers. According to Höss, they were obviously shaken by this but "it never led to any incident". He mentioned the case of a who found the body of his wife, yet continued to drag corpses along "as though nothing had happened". At Auschwitz, the corpses were incinerated in crematoria and the ashes either buried, scattered, or dumped in the river. At

The efficiency of industrialised murder at Auschwitz-Birkenau led to the construction of three buildings with crematoria designed by specialists from the firm J. A. Topf & Söhne.

Victims

The estimated total number of people who were murdered in the six Nazi extermination camps is 2.7 million, according to the United States Holocaust Memorial Museum.


Dismantling and attempted concealment

The Nazis attempted to either partially or completely dismantle the extermination camps in order to hide any evidence that people had been murdered there. This was an attempt to conceal not only the extermination process but also the buried remains. As a result of the secretive , the camps were dismantled by commandos of condemned prisoners, their records were destroyed, and the mass graves were dug up. Some extermination camps that remained uncleared of evidence were liberated by Soviet troops, who followed different standards of documentation and openness than the Western allies did. Nonetheless

The camps and Holocaust denial

Holocaust deniers or negationists are people and organizations who assert that the Holocaust did not occur, or that it did not occur in the historically recognized manner and extent. Holocaust deniers claim that the extermination camps were actually transit camps from which Jews were deported farther east. However, these theories are disproven by surviving German documents, which show that Jews were sent to the camps to be murdered. Extermination camp research is difficult because of extensive attempts by the SS and Nazi regime to conceal the existence of the extermination camps. The existence of the extermination camps is firmly established by testimonies of camp survivors and Final Solution perpetrators, material evidence (the remaining camps, etc.), Nazi photographs and films of the killings, and camp administration records.
