Extermination Camp

Nazi Germany established six extermination camps, referred to as Vernichtungslager in German, and also known as death camps (Todeslager) or killing centers (Tötungszentren), within Central Europe. These were primarily situated in German-occupied Poland during World War II . Their grim purpose was the systematic murder of over 2.7 million people, predominantly Jews , as part of the Holocaust . The primary method of extermination involved gassing , utilizing either purpose-built stationary installations or mobile gas vans . The six designated extermination camps were Chełmno , Bełżec , Sobibór , Treblinka , Auschwitz-Birkenau , and Majdanek . At Auschwitz and Majdanek, the horrific practice of extermination through labour was also employed. Beyond these specific sites, millions more perished in concentration camps , through the Aktion T4 program, or via direct execution. It is also important to note that camps operated by Nazi allies, such as the Jasenovac concentration camp in the Independent State of Croatia , have also been identified as extermination or death camps.

The National Socialists were not secretive about the existence of concentration camps, which they established as early as 1933 to deter any form of resistance. The extermination camps, however, were shrouded in extreme secrecy. To mask the true nature of the mass murders, internal Nazi communications referred to the killings with euphemisms such as “special treatment,” “cleansing,” “resettlement,” or “evacuation.” The SS itself often used the term “concentration camp” to refer to these extermination facilities, and their administrative structures bore significant resemblances. The specific term “extermination camp” gained prominence later, primarily within historical scholarship and legal proceedings, serving to further categorize these distinct sites of atrocity.

The chilling concept of mass extermination utilizing stationary facilities, to which victims were transported by train , emerged from earlier Nazi experiments. These experiments involved the use of chemically manufactured poison gas during the clandestine Aktion T4 euthanasia program, which targeted hospital patients with mental and physical disabilities . This technology was subsequently adapted, scaled up, and deployed against a vast array of unsuspecting victims from numerous ethnic and national groups. The primary targets, however, were the Jews of Europe, who constituted over 90 percent of those murdered in the extermination camps. This systematic genocide of European Jews was the Nazi regime’s so-called “Final Solution to the Jewish question ”.

Background

Following the invasion of Poland in September 1939, the secret Aktion T4 euthanasia program was initiated by the SS . This program systematically murdered German, Austrian, and Polish hospital patients with mental or physical disabilities, a policy authorized by Hitler . The explicit aim was to eliminate “life unworthy of life ” (German: Lebensunwertes Leben), a Nazi designation for individuals deemed to have no right to life . By 1941, the experience and techniques developed in the secretive killing of these hospital patients directly informed the creation of extermination camps for the implementation of the Final Solution. By this stage, Jews were already being confined to newly established ghettos and interned in Nazi concentration camps alongside other targeted groups, including Roma and Soviet POWs . The Nazi regime’s so-called “Final Solution of the Jewish Question ”, which centered on the systematic murder of Europe’s Jews through gassing, commenced during Operation Reinhard , following the onset of the Nazi–Soviet war in June 1941. The adoption of gassing technology by Nazi Germany was preceded by a brutal wave of direct killings carried out by the SS Einsatzgruppen , who advanced with the Wehrmacht army during Operation Barbarossa on the Eastern Front.

The extermination camps, specifically designed for the mass gassing of Jews, were established in the months after the Wannsee Conference . This conference, chaired by Reinhard Heydrich in January 1942, unequivocally affirmed the policy of exterminating Europe’s Jews. The logistical coordination of this horrific undertaking was assigned to Adolf Eichmann .

On October 13, 1941, Odilo Globocnik , the SS and Police Leader stationed in Lublin , received a verbal directive from Reichsführer-SS [Heinrich Himmler]. This order, issued in anticipation of the fall of Moscow , mandated the immediate commencement of construction on the killing center at Bełżec in the General Government territory of occupied Poland. Significantly, this order predated the Wannsee Conference by three months. Meanwhile, the gassings at Chełmno , north of Łódź , utilizing gas vans , had already begun in December under the command of Sturmbannführer Herbert Lange . The Bełżec camp became operational by March 1942, with leadership personnel brought in from Germany under the guise of Organisation Todt (OT). By mid-1942, two additional death camps were constructed on Polish territory for Operation Reinhard: Sobibór , completed in May 1942, under the command of Hauptsturmführer Franz Stangl ; and Treblinka , operational by July 1942, led by Obersturmführer Irmfried Eberl , who was notably a doctor from the T4 program. Auschwitz concentration camp was equipped with new gas chambers in March 1942, and Majdanek followed suit with its own gas chambers constructed in September.

The Nazis maintained a distinction between extermination camps and concentration camps. The terms “extermination camp” (Vernichtungslager) and “death camp” (Todeslager) were used interchangeably within the Nazi system, both referring to camps whose primary purpose was genocide . While six camps fit this specific definition, it is crucial to understand that the extermination of individuals occurred across virtually all types of Nazi camps, including concentration and transit camps. The designation “extermination camp” with its singular focus on mass killing is a term carried over from Nazi terminology. The six camps identified as such were Chełmno , Bełżec , Sobibór , Treblinka , Majdanek , and Auschwitz (also known as Auschwitz-Birkenau).

Death camps were meticulously designed for the systematic murder of people who arrived in mass transports via the Holocaust trains . At Bełżec, Sobibór, and Treblinka, deportees were typically murdered within mere hours of their arrival. The extermination camps associated with Einsatz Reinhard operated under the direct command of Globocnik. Each of these camps was managed by a small contingent of 20 to 35 men from the SS-Totenkopfverbände branch of the Schutzstaffel , supplemented by approximately one hundred Trawnikis —auxiliary personnel, predominantly recruited from Soviet Ukraine—and up to a thousand slave laborers forming Sonderkommando units. The Jewish men, women, and children arriving at these camps were brought from the ghettos for “special treatment,” subjected to an atmosphere of pervasive terror orchestrated by uniformed police battalions from both the Orpo and Schupo forces.

These death camps stood in stark contrast to concentration camps located within Germany proper, such as Bergen-Belsen , Oranienburg , Ravensbrück , and Sachsenhausen . The latter had been established prior to World War II as detention facilities for individuals deemed “undesirable.” From March 1936 onwards, all Nazi concentration camps were administered by the SS-Totenkopfverbände (the “Skull Units”), who also operated the extermination camps from 1941. An SS anatomist , Johann Kremer , documented his experience after witnessing the gassing of victims at Birkenau in his diary on September 2, 1942: “Dante’s Inferno seems to me almost a comedy compared to this. They don’t call Auschwitz the camp of annihilation for nothing!” This distinction was further clarified during the Nuremberg trials , when Dieter Wisliceny , a deputy to Adolf Eichmann , was questioned about the extermination camps. He identified Auschwitz and Majdanek as such. When subsequently asked about the classification of camps like Mauthausen , Dachau , and Buchenwald , he replied, “They were normal concentration camps, from the point of view of the department of Eichmann.”

The systematic murders were not confined solely to these designated extermination camps. Sites of “Holocaust by Bullets” are also marked on maps of occupied Poland, often indicated by white skulls, where victims were summarily shot and buried in mass graves. Notable locations include Bronna Góra , Ponary , and Rumbula , among others.

Mass deportations: the pan-European routes to the extermination camps

Beyond the systematic round-ups for extermination camps, the Nazis abducted millions of foreigners for slave labour in other types of camps . This practice provided a convenient cover for the extermination program. Prisoners constituted approximately a quarter of the total workforce within the Reich, and mortality rates often exceeded 75 percent due to starvation, disease, exhaustion, executions, and systematic brutality.

History

In the early years of World War II, Jews were primarily relegated to forced labor camps and ghettos. However, from 1942 onward , they began to be deported to the extermination camps under the pretext of “resettlement.” For both political and logistical considerations, the most infamous Nazi German killing factories were constructed in occupied Poland . This strategic choice was driven by the fact that the majority of the intended victims resided in Poland, which harbored the largest Jewish population in German-controlled Europe . Furthermore, establishing these new death camps outside of Germany’s pre-war borders offered a degree of secrecy from the German civilian populace.

Pure extermination camps

During the initial phase of the Final Solution , gas vans that produced poisonous exhaust fumes were developed and utilized in the occupied Soviet Union (USSR) and at the Chełmno extermination camp in occupied Poland , before their deployment elsewhere. This method of killing was informed by the experience gained by the SS during the clandestine Aktion T4 program of involuntary euthanasia . Two distinct types of death chambers were employed during the Holocaust.

In contrast to 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 —constructed during Operation Reinhard (October 1941 – November 1943)—utilized lethal exhaust fumes generated by large internal combustion engines . The three killing centers of Einsatz Reinhard were primarily built for the extermination of Poland’s Jews who were trapped within the Nazi ghettos . Initially, the bodies of the victims were buried using crawler excavators , but they were later exhumed and cremated in open-air pyres as part of an effort to conceal the evidence of genocide, a process known as Sonderaktion 1005 .

The six camps considered to be exclusively for extermination were the Chełmno extermination camp , Bełżec extermination camp , Sobibor extermination camp , Treblinka extermination camp , Majdanek extermination camp , and Auschwitz extermination camp (also referred to as Auschwitz-Birkenau).

While Auschwitz II (Auschwitz–Birkenau) and Majdanek were part of larger labor camp complexes, the Chełmno and the Operation Reinhard death camps (namely Bełżec, Sobibór, and Treblinka) were established with the sole purpose of rapidly exterminating entire communities, primarily Jews, within hours of their arrival. All these camps were strategically located near branch lines connected to the Polish railway network. They were staffed by minimal personnel and equipped with only basic support installations, not designed to accommodate the vast numbers of victims arriving in railway transports .

Upon arrival, the Nazis employed deception, informing victims that they had reached a temporary transit stop and would soon be moved to German Arbeitslager (work camps) further east. A select group of able-bodied prisoners were not immediately killed but were forced into labor units known as Sonderkommandos . Their horrific task was to assist in the extermination process by removing corpses from the gas chambers and managing their disposal.

Concentration and extermination camps

The notorious Sonderkommando were compelled to burn the bodies of victims in fire pits at Auschwitz II-Birkenau when the crematoria were overloaded. (August 1944) [29]

At the camps of Operation Reinhard, including Bełżec , Sobibór , and Treblinka , trainloads of prisoners were murdered immediately upon arrival in gas chambers specifically constructed for this purpose. [15] The facilities for mass killing were developed concurrently within the Auschwitz II-Birkenau subcamp, which was part of a forced labour complex , and at the Majdanek concentration camp . [15] In most other camps, prisoners were initially selected for slave labor and kept alive on starvation rations, made available for work as needed. Auschwitz, Majdanek, and Jasenovac were progressively equipped with Zyklon B gas chambers and crematoria buildings, remaining operational until the war’s end in 1945. [47]

Extermination procedure

In 1941, Heinrich Himmler visited the vicinity of Minsk to observe a mass shooting. He was reportedly informed by the commanding officer that the shootings were having a detrimental psychological impact on the soldiers tasked with carrying them out. Consequently, Himmler concluded that a more detached method of mass killing was necessary. [48] [49] Auschwitz Commandant Rudolf Höss claimed in his memoir that many members of the Einsatzkommandos were “unable to endure wading through blood any longer” and subsequently went mad or committed suicide, though he provided no specific figures to substantiate this assertion. [50]

The Nazis initially employed gassing with carbon monoxide cylinders to murder approximately 70,000 disabled individuals in Germany, under the guise of a ’euthanasia programme’ intended to conceal the mass murder taking place. Despite the lethal efficacy of carbon monoxide, this method was deemed unsuitable for use in the East due to the logistical and financial burden of transporting the gas in cylinders. [51] [ better source needed ]

Each extermination camp operated with its own specific procedures, yet all were designed for swift and industrialized killing. During an official absence of Höss in late August 1941, his deputy, Karl Fritzsch , experimented with a new approach. At Auschwitz, clothing infested with lice was treated with crystallized prussic acid . These crystals, a product of the IG Farben chemical company, were branded as Zyklon B. Upon release from their containers, the Zyklon B crystals would release a lethal cyanide gas into the air. Fritzsch tested the effects of Zyklon B on Soviet POWs, who were confined to basement cells in the camp’s bunker for this experiment. Upon his return, Höss was briefed and reportedly impressed by the results, leading to the adoption of this method as the camp’s primary strategy for extermination, a practice that was also implemented at Majdanek. Alongside gassing, camp guards continued to kill prisoners through mass shootings, starvation, torture, and other brutal means. [52]

Gassings

SS Obersturmführer Kurt Gerstein , affiliated with the Institute for Hygiene of the Waffen-SS , provided testimony to a Swedish diplomat during the war regarding his experiences in a death camp. He recounted his arrival at Bełżec extermination camp on August 19, 1942. The camp was equipped with carbon monoxide gas chambers. Gerstein witnessed the unloading of 45 train cars containing 6,700 Jews, a significant number of whom were already deceased. The survivors were then forced to march naked to the gas chambers , where the following occurred:

Unterscharführer Hackenholt was making great efforts to get the engine running. But it doesn’t go. Captain Wirth comes up. I can see he is afraid, because I am present at a disaster. Yes, I see it all and I wait. My stopwatch showed it all, 50 minutes, 70 minutes, and the diesel [engine] did not start. The people wait inside the gas chambers. In vain. They can be heard weeping, “like in the synagogue”, says Professor Pfannenstiel, his eyes glued to a window in the wooden door. Furious, Captain Wirth lashes the Ukrainian (Trawnikis ) assisting Hackenholt twelve, thirteen times, in the face. After 2 hours and 49 minutes – the stopwatch recorded it all – the diesel started. Up to that moment, the people shut up in those four crowded chambers were still alive, four times 750 persons, in four times 45 cubic meters. Another 25 minutes elapsed. Many were already dead, that could be seen through the small window, because an electric lamp inside lit up the chamber for a few moments. After 28 minutes, only a few were still alive. Finally, after 32 minutes, all were dead… Dentists [then] hammered out gold teeth, bridges, and crowns. In the midst of them stood Captain Wirth. He was in his element, and, showing me a large can full of teeth, he said: “See, for yourself, the weight of that gold! It’s only from yesterday, and the day before. You can’t imagine what we find every day – dollars, diamonds, gold. You’ll see for yourself!”

— Kurt Gerstein [53]

A photograph from the Auschwitz Album depicts the march of new arrivals along the SS barracks at Birkenau towards the gas chambers located near crematoria II and III, dated May 27, 1944.

Auschwitz Camp Commandant Rudolf Höss reported that during the initial deployment of Zyklon B pellets against Jews, many prisoners harbored suspicions of their impending demise, despite being deceived with claims of delousing and subsequent return to the camp. [54] Consequently, the Nazis identified and isolated individuals deemed “difficult” who might incite unrest among the majority of prisoners being led to the gas chambers. These “difficult” prisoners were taken to a secluded area and executed discreetly.

According to Höss, prisoners forced into Sonderkommando (Special Detachment) service assisted in the extermination process. They were tasked with encouraging Jews to undress and accompanying them into the gas chambers, which were designed to resemble shower rooms with non-functional water nozzles and tiled walls. They remained with the victims until the chamber doors were about to be sealed. To maintain the deceptive “calming effect” of the delousing charade, an SS man stood at the door until the very end. The Sonderkommando members engaged in conversations with the victims about camp life to pacify those who were suspicious and to hasten their entry; they also assisted the elderly and very young in undressing. [55] Many young mothers, fearing that the delousing “disinfectant” might harm their infants, would hide them beneath their piled clothing. Camp Commandant Höss noted that the “men of the Special Detachment were particularly on the look-out for this,” and actively encouraged women to take their children into the “shower room.” Likewise, the Sonderkommando provided comfort to older children who might cry “because of the strangeness of being undressed in this fashion.” [56]

However, not all prisoners were successfully deceived by these tactics. Commandant Höss described instances 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 emit “the most terrible shrieks while undressing, or tear their hair, or scream like maniacs”; these individuals were removed for execution by shooting. [57] In such dire circumstances, some prisoners, in a desperate attempt to save themselves at the threshold of the gas chamber, betrayed the identities of “those members of their race still in hiding” and revealed their addresses. [58]

Once the door of the filled gas chamber was sealed, pellets of Zyklon B were introduced through specialized openings in the roof. Regulations mandated that the Camp Commandant personally supervise the preparations, the gassing process (observed through a peephole), and the subsequent looting of the corpses. Commandant Höss reported that the gassed victims “showed no signs of convulsion”; the Auschwitz camp physicians attributed this to the “paralyzing effect on the lungs” of the Zyklon B gas, which killed before the onset of convulsions. [59] The corpses were discovered in a semi-squatting position, their skin discolored a pinkish hue with red and green spots, some exhibiting foaming at the mouth or bleeding from their ears, conditions exacerbated by the extreme crowding within the gas chambers. [60]

The remnants of “Crematorium II,” used at Auschwitz-Birkenau between March 1943 and its destruction by the Schutzstaffel on January 20, 1945.

Fifty-two crematorium ovens, including these, were utilized to burn the bodies of up to 6,000 people every 24 hours during the operation of the Auschwitz-Birkenau gas chambers. [9]

As part of their political indoctrination, certain high-ranking Nazi Party leaders and SS officers were sent to Auschwitz–Birkenau to witness the gassings. Camp Commandant Rudolf Höss justified the extermination by emphasizing the necessity of “the iron determination with which we must carry out Hitler’s orders.” [61]

Corpse disposal

Following the gassings, the Sonderkommando were responsible for removing the corpses from the gas chambers and extracting any gold teeth. Initially, the victims were interred in mass graves. However, during Sonderaktion 1005 , corpses were subsequently cremated in open-air pyres at all camps associated with Operation Reinhard .

The Sonderkommando were tasked with burning the corpses in the pits, [62] stoking the fires, draining excess body fat, and turning over the “mountain of burning corpses … so that the draft might fan the flames,” as Commandant Höss described in his memoir while in Polish custody. [62] He expressed astonishment at the diligence of the prisoners from the so-called Special Detachment, who performed their duties with remarkable composure despite being acutely aware that they themselves would ultimately meet the same fate. [62] At the Lazaret killing station, they were responsible for holding the sick so they would not witness their own execution by shooting. They performed this task “in such a matter-of-course manner that they might, themselves, have been the exterminators,” Höss wrote. [62] He further observed that these men would eat and smoke “even when engaged in the grisly job of burning corpses which had been lying for some time in mass graves.” [62] Occasionally, they encountered the remains of a relative or witnessed individuals they knew entering the gas chambers. According to Höss, while visibly shaken by these discoveries, they “never led to any incident.” He cited the instance of a Sonderkommando member who found the body of his wife but continued to drag corpses along “as though nothing had happened.” [62]

At Auschwitz, the corpses were incinerated in crematoria , and the ashes were either buried, scattered, or disposed of in the river. At Sobibór , Treblinka , Bełżec , and Chełmno , the corpses were cremated on pyres. The sheer efficiency of industrialized murder at Auschwitz-Birkenau necessitated the construction of three buildings equipped with crematoria, designed by specialists from the firm J. A. Topf & Söhne . These facilities operated 24 hours a day, yet the rate of death was sometimes so high that additional burning of corpses in open-air pits became necessary. [63]

Victims

The estimated total number of individuals murdered in the six Nazi extermination camps stands at 2.7 million, according to the United States Holocaust Memorial Museum. [3] All six of these camps were located in what is now Poland.

Dismantling and attempted concealment

The Nazis made concerted efforts to dismantle the extermination camps, either partially or entirely, in a desperate attempt to erase any evidence of the mass murders. This was not only an effort to conceal the extermination process itself but also to oblimate the physical remains of the victims. Through the clandestine Sonderaktion 1005 , condemned prisoners were forced to exhume mass graves, destroy records, and dismantle camp structures. Some extermination camps, where evidence remained intact, were liberated by Soviet troops, whose documentation and transparency standards differed from those of the Western Allies. [70] [71]

Despite these efforts, Majdanek was captured in a relatively intact state due to the rapid advance of the Soviet Red Army during [Operation Bagration]. [70]

Commemoration

In the post-war era, the government of the People’s Republic of Poland erected monuments at the sites of the extermination camps. These early memorials were notable for their omission of any specific ethnic, religious, or national identification of the victims. In recent decades, the former extermination camp sites have become accessible to the public and are popular destinations for visitors from around the globe, with the infamous Auschwitz, near the town of Oświęcim , being particularly prominent. In the early 1990s, a debate arose between Jewish Holocaust organizations and Polish Catholic groups regarding the appropriateness of religious symbols, particularly Christian ones like the Auschwitz cross , near Auschwitz I, where the majority of victims were Polish. The Jewish victims of the Holocaust were predominantly murdered at Auschwitz II Birkenau.

The March of the Living has been organized annually in Poland since 1988, drawing participants from diverse countries including Estonia , New Zealand , Panama , and Turkey .

The camps and Holocaust denial

Holocaust deniers, or negationists , are individuals and organizations who dispute the occurrence of the Holocaust or its historically recognized scale and nature. [74] Deniers often contend that the extermination camps were merely transit camps from which Jews were deported further east. However, these theories are demonstrably false, contradicted by surviving German documents that unequivocally prove Jews were sent to these camps for the express purpose of murder. [75]

Research into extermination camps is inherently challenging due to the extensive measures undertaken by the SS and the Nazi regime to conceal their existence. [70] Nevertheless, the reality of these camps is firmly established through the testimonies of survivors and perpetrators, material evidence (including the remaining camp structures), Nazi photographs and films documenting the killings, and official camp administration records. [76] [77]

Awareness

A 2017 survey conducted by the Körber Foundation revealed that 40 percent of 14-year-old students in Germany were unaware of Auschwitz . [78] [79] A subsequent 2018 survey, organized in the United States by the Claims Conference , the United States Holocaust Memorial Museum , and other organizations, found that 66 percent of American millennials surveyed (and 41 percent of all U.S. adults) did not recognize Auschwitz. [80] In 2019, a survey of 1,100 Canadians indicated that nearly half (49 percent) could not name a single Nazi camp located in German-occupied Europe . [81]
