Extermination camp

 ( Internments ) 

Death camps differed from concentration camps located in Germany proper, such as Bergen-Belsen, Oranienburg, Ravensbrück, and Sachsenhausen, which were prison camps set up prior to World War II for people defined as 'undesirable'. From March 1936, all Nazi concentration camps were managed by the SS-Totenkopfverbände (the Skull Units, SS-TV), who operated extermination camps from 1941 as well.

Unlike at Auschwitz, where cyanide-based Zyklon B was used to exterminate trainloads of prisoners under the guise of "relocation", the camps at Treblinka, Bełżec, and Sobibór, built during Operation Reinhard (October 1941November 1943), used lethal exhaust fumes produced by large internal combustion engines. The three killing centres of Einsatz Reinhard were constructed predominantly for the extermination of Polish Jews trapped in the Nazi ghettos. At first, the victims' bodies were buried with the use of crawler excavators, but they were later exhumed and incinerated in open-air pyres to hide the evidence of genocide in what became known as Sonderaktion 1005.

Auschwitz Camp Commandant Rudolf Höss reported that the first time Zyklon B 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.

According to Höss, enslaved prisoners, euphemistically called Sonderkommando (Special Detachment), assisted in the process of extermination; they encouraged the Jews to undress and accompanied them into the gas chambers which were 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 Sonderkommando 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. 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 Sonderkommando comforted older children who might cry "because of the strangeness of being undressed in this fashion".

Yet, not every prisoner was deceived by such tactics; Commandant Höss spoke of Jews "who either guessed, or knew, what awaited them, nevertheless ... they 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"; these prisoners were taken 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.

As a matter of political training, some high-ranked Nazi Party leaders and SS officers were sent to Auschwitz–Birkenau to witness the gassings. As the Auschwitz Camp Commandant Rudolf Höss justified the extermination by explaining the need for "the iron determination with which we must carry out Hitler's orders".

The Sonderkommando 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 Sonderkommando 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 crematorium and the ashes either buried, scattered, or dumped in the river. At Sobibór, Treblinka, Bełżec, and Chełmno, the corpses were incinerated on pyres. 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. They burned bodies 24 hours a day, and yet the death rate was at times so high that corpses also needed to be burned in open-air pits.

Nonetheless Majdanek was captured nearly intact due to the rapid advance of the Soviet Red Army during Operation Bagration.

The March of the Living is organized in Poland annually since 1988. Marchers come from countries as diverse as Estonia, New Zealand, Panama, and Turkey.

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.
