Operation Reinhard or Operation Reinhardt (German: Aktion Reinhard or Aktion Reinhardt; also Einsatz Reinhard or Einsatz Reinhardt) was the codename of the secretive German plan in World War II to exterminate Polish Jews in the General Government district of German-occupied Poland. This deadliest phase of the Holocaust was marked by the introduction of extermination camps.
As many as two million Jews were sent to Bełżec, Sobibór, and Treblinka to be murdered in purpose-built gas chambers. In addition, mass-killing facilities, using Zyklon B, were developed at about the same time at the Majdanek concentration camp and at Auschwitz II-Birkenau, near the earlier-established Auschwitz I camp for ethnically Polish prisoners.
After the German–Soviet war began, the Nazis decided to undertake the European-wide Final Solution to the Jewish Question. In January 1942, during a secret meeting of German leaders chaired by Reinhard Heydrich, Operation Reinhard was drafted; soon to become a major step in the systematic murder of the Jews in occupied Europe, beginning in the General Government district of German-occupied Poland. Within months, three top-secret camps (at Bełżec, Sobibór, and Treblinka) were built to efficiently kill tens of thousands of Jews every day. These camps differed from Auschwitz and Majdanek, because the latter operated as forced-labour camps initially, before they became death camps fitted with crematoria. Unlike "mixed" extermination camps, the extermination camps of Operation Reinhard kept no prisoners, except as a means of furthering the camps' sole purpose of industrial scale murder. Very few Jews successfully escaped death (notably, only two at Bełżec). All other victims were killed on arrival.
The organizational apparatus behind the new extermination plan had been put to the test already during the euthanasia Aktion T4 programme ending in August 1941, which resulted in the murders of more than 70,000 Polish and German disabled men, women, and children. The SS officers responsible for the Aktion T4, including Christian Wirth, Franz Stangl, and Irmfried Eberl, were all given key roles in the implementation of the "Final Solution" in 1942.
The origin of the operation's name is debated by Holocaust researchers. Various German documents spell the name differently, some with "t" after "d" (as in "Aktion Reinhardt"), others without it. Yet another spelling (Einsatz Reinhart) was used in the Höfle Telegram. It is generally believed that Aktion Reinhardt, outlined at the Wannsee Conference on 20 January 1942, was named after Reinhard Heydrich, the coordinator of the so-called Final Solution of the Jewish Question, which entailed the extermination of the Jews living in the European countries occupied by Nazi Germany. Heydrich was attacked by British-trained Czechoslovakian agents on 27 May 1942 and died of his injuries eight days later. The earliest memo spelling out Einsatz Reinhard was relayed two months later.
On 13 October 1941, SS and Police Leader Odilo Globočnik headquartered in Lublin received an oral order from Himmler – anticipating the fall of Moscow – to start immediate construction work on the first killing centre at Bełżec in the General Government territory of occupied Poland. Notably, the order preceded the Wannsee Conference by three months. The new camp was operational beginning 17 March 1942, with leadership brought in from Germany under the guise of Organisation Todt (OT).
Globočnik was given control over the entire programme. All highly secretive orders he received came directly from Himmler and not from SS-Gruppenführer Richard Glücks, head of the greater Nazi concentration camp system, which was run by the SS-Totenkopfverbände and engaged in slave labour for the war effort. Each death camp was managed by between 20 and 35 officers from the Totenkopfverbände (Death's Head Units) sworn to absolute secrecy, and augmented by the Aktion T4 personnel selected by Globočnik. The extermination program was designed by them based on prior experience from the forced euthanasia centres. The bulk of the actual labour at each "final solution" camp was performed by up to 100 mostly Ukrainian Trawniki guards, recruited by SS-Hauptsturmführer Karl Streibel from among the Soviet prisoners of war, and by up to a thousand Sonderkommando prisoners whom the Trawniki guards used to terrorise. The SS called their volunteer guards "Hiwis", an abbreviation of Hilfswillige (lit. "willing to help"). According to the testimony of SS-Oberführer Arpad Wigand during his 1981 war crimes trial in Hamburg, only 25 percent of recruited collaborators could speak German.
By mid-1942, two more death camps had been built on Polish lands: Sobibór (operational by May 1942) under the leadership of SS-Hauptsturmführer Franz Stangl, and Treblinka (operational by July 1942) under SS-Obersturmführer Irmfried Eberl.
The killing mechanism consisted of a large internal-combustion engine pumping exhaust fumes into rooms through long pipes. Starting in February–March 1943 the bodies of the dead were exhumed and cremated in pits. Treblinka, the last camp to become operational, used knowledge learned by the SS previously. With two powerful engines,[a] run by SS-Scharführer Erich Fuchs, and the gas chambers soon rebuilt of bricks and mortar, this death factory had killed between 800,000 and 1,200,000 people within 15 months, disposed of their bodies, and sorted their belongings for shipment to Germany.
The techniques used to deceive victims and the camps' overall layout were based on a pilot project of mobile killing conducted at the Chełmno extermination camp (Kulmhof), which began operating in late 1941 and used gas vans. Chełmno was not a part of Reinhard. It came under the direct control of SS-Standartenführer Ernst Damzog, commander of the SD in Reichsgau Wartheland. It was set up around a manor house similar to Sonnenstein. The use of gas vans had been previously tried and tested in the mass killing of Polish prisoners at Soldau, and in the extermination of Jews on the Russian Front by the Einsatzgruppen. Between early December 1941 and mid-April 1943, 160,000 Jews were sent to Chełmno from the General Government via the Ghetto in Łódź. Chełmno did not have crematoria; only the mass graves in the woods. It was a testing ground for the establishment of faster methods of killing and incinerating people, marked by the construction of stationary facilities for the mass murder a few months later. The Reinhard death camps adapted progressively as each new site was built.
Taken as a whole, Globočnik's camps at Bełżec, Sobibór, and Treblinka had almost identical design, including staff members transferring between locations. The camps were situated within wooded areas well away from population centres. All were constructed near branch lines that linked to the Ostbahn. Each camp had an unloading ramp at a fake railway station, as well as a reception area that contained undressing barracks, barber shops, and money depositories. Beyond the receiving zone, at each camp was a narrow, camouflaged path known as the Road to Heaven (called Himmelfahrtsstraße or der Schlauch by the SS), which led to the extermination zone consisting of gas chambers, and the burial pits, up to 10 metres (33 ft) deep, later replaced by cremation pyres with rails laid across the pits on concrete blocks; refuelled continuously by the Totenjuden. Both Treblinka and Bełżec were equipped with powerful crawler excavators from Polish construction sites in the vicinity, capable of most digging tasks without disrupting surfaces. At each camp, the SS guards and Ukrainian Trawnikis lived in a separate area from the Jewish work units. Wooden watchtowers and barbed-wire fences camouflaged with pine branches surrounded all camps.
The killing centres had no electric fences, as the size of the prisoner Sonderkommandos (work units) remained relatively easy to control – unlike in camps such as Dachau and Auschwitz. To assist with the arriving transports only specialised squads were kept alive, removing and disposing of bodies, and sorting property and valuables from the dead victims. The Totenjuden forced to work inside death zones were kept in isolation from those who worked in the reception and sorting area. Periodically, those who worked in the death zones would be killed and replaced with new arrivals to remove any potential witnesses to the scale of the mass murder.
During Operation Reinhard, Globočnik oversaw the systematic killing of more than 2,000,000 Jews from Poland, Czechoslovakia, France, the Reich (Germany and Austria), the Netherlands, Greece, Hungary, Italy and the Soviet Union. An undetermined number of Roma were also killed in these death camps, many of them children.
To achieve their purposes, all death camps used subterfuge and misdirection to conceal the truth and trick their victims into cooperating. This element had been developed in Aktion T4, when disabled and handicapped people were taken away for "special treatment" by the SS from "Gekrat" wearing white laboratory coats, thus giving the process an air of medical authenticity. After supposedly being assessed, the unsuspecting T4 patients were transported to killing centres. The same euphemism "special treatment" (Sonderbehandlung) was used in the Holocaust.
The SS used a variety of ruses to move thousands of new arrivals travelling in Holocaust trains to the disguised killing sites without panic. Mass deportations were called "resettlement actions"; they were organised by special Commissioners and conducted by uniformed police battalions from Orpo and Schupo in an atmosphere of terror. Usually, the deception was absolute; in August 1942, people of the Warsaw Ghetto lined up for several days to be "deported" to obtain bread allocated for travel. Jews unable to move or attempting to flee were shot on the spot. Even though death in the cattle cars from suffocation and thirst was rampant, affecting up to 20 percent of trainloads, most victims were willing to believe that the German intentions were different. Once alighted, the prisoners were ordered to leave their luggage behind and march directly to the "cleaning area" where they were asked to hand over their valuables for "safekeeping". Common tricks included the presence of a railway station with awaiting "medical personnel" and signs directing people to disinfection facilities. Treblinka also had a booking office with boards naming the connections for other camps further east.
The Jews most apprehensive of danger were brutally beaten to speed up the process. At times, the new arrivals who had suitable skills were selected to join the Sonderkommando. Once in the changing area, the men and boys were separated from the women and children and everyone was ordered to disrobe for a communal bath: "quickly – they were told – or the water will get cold". The old and sick, or slow, prisoners were taken to a fake infirmary named the Lazarett, that had a large mass grave behind it. They were killed by a bullet in the neck, while the rest were being forced into the gas chambers.
To drive the naked people into the execution barracks housing the gas chambers, the guards used whips, clubs, and rifle butts. Panic was instrumental in filling the gas chambers because the need to evade blows on their naked bodies forced the victims rapidly forward. Once packed tightly inside (to minimize available air), the steel air-tight doors with portholes were closed. The doors, according to Treblinka Museum research, originated from the Soviet military bunkers around Białystok. Although other methods of extermination, such as the cyanic poison Zyklon B, were already being used at other Nazi killing centres such as Auschwitz, the Aktion Reinhard camps used lethal exhaust gases from captured Soviet tank engines. Fumes would be discharged directly into the gas chambers for a given period, then the engines would be switched off. SS guards would determine when to reopen the gas doors based on how long it took for the screaming to stop from within (usually 25 to 30 minutes). Special teams of camp inmates (Sonderkommando) would then remove the corpses on flatbed carts. Before the corpses were thrown into grave pits, gold teeth were removed from mouths, and orifices were searched for jewellery, currency, and other valuables. All acquired goods were managed by the SS-Wirtschafts-Verwaltungshauptamt (Main SS Economic and Administrative Department).
During the early phases of Operation Reinhard, victims were simply thrown into mass graves and covered with lime. From 1943, to hide the evidence of the crime, all bodies were burned in open air pits. Special Leichenkommando (corpse units) had to exhume bodies from the mass graves around these death camps for incineration. Reinhard still left a paper trail; in January 1943, Bletchley Park intercepted an SS telegram by SS-Sturmbannführer Hermann Höfle, Globočnik's deputy in Lublin, to SS-Obersturmbannführer Adolf Eichmann in Berlin. The decoded Enigma message contained statistics showing a total of 1,274,166 arrivals at the four Aktion Reinhard camps until the end of 1942 but the British code-breakers did not understand the meaning of the message, which amounted to material evidence of how many people the Germans had murdered.

Temporary substitution policy
In the winter of 1941, before the Wannsee Conference but after the commencement of Operation Barbarossa, the Nazi demands for forced labor greatly intensified. Himmler and Heydrich approved a Jewish substitution policy in Upper Silesia and in Galicia under the "extermination through labour" doctrine. Many Poles had already been sent to the Reich, creating a labour shortage in the General Government. Around March 1942, while the first extermination camp (Bełżec) began gassing, the deportation trains arriving in the Lublin reservation from Germany and Slovakia were searched for the Jewish skilled workers. After selection, they were delivered to Majdan Tatarski instead of for "special treatment" at Bełżec. For a short time, these Jewish laborers were temporarily spared death, while their families and all others were murdered. Some were relegated to work at a nearby airplane factory or as forced labor in the SS-controlled Strafkompanies and other work camps. Hermann Höfle was one of the chief supporters and implementers of this policy. There were problems with food supplies and the ensuing logistical challenges. Globočnik and Friedrich-Wilhelm Krüger complained and the mass transfer was stopped even before the three extermination camps were operational.
Disposition of the property of the victims
Approximately 178 million German Reichsmarks' worth of Jewish property (equivalent to 672 million 2017 euros) was taken from the victims, with vast transfers of gold and valuables to the Reichsbank's "Melmer" account, Gold Pool, and monetary reserve. But this wealth did not only go to the German authorities, because corruption was rife within the death camps. Many of the individual SS members and policemen involved in the killings took cash, property, and valuables for themselves. The higher-ranking SS men stole on an enormous scale. It was a common practice among the top echelon. Two Majdanek commandants, Karl-Otto Koch and Hermann Florstedt, were tried by the SS for it in April 1945. SS-Sturmbannführer Georg Konrad Morgen, an SS judge from the SS Courts Office, prosecuted so many Nazi officers for individual violations that Himmler personally ordered him to restrain his cases by April 1944.
Aftermath and cover up
Operation Reinhard ended in November 1943. Most of the staff and guards were then sent to northern Italy for further Aktion against Jews and local partisans. Globočnik went to the San Sabba concentration camp, where he supervised the detention, torture and killing of political prisoners. To cover up the mass murder of more than two million people in Poland during Operation Reinhard, the Nazis implemented the secret Sonderaktion 1005, also called Aktion 1005 or Enterdungsaktion ("exhumation action"). The operation, which began in 1942 and continued until the end of 1943, was designed to remove all traces that mass murder. Leichenkommando ("corpse units") comprising camp prisoners were created to exhume mass graves and cremate the buried bodies, using giant grills made from wood and railway tracks. Afterwards, bone fragments were ground up in special milling machines, and all remains were then re-buried in new pits. The Aktion was overseen by squads of Trawniki guards. After the war, some of the SS officers and guards were tried and sentenced at the Nuremberg trials for their role in Operation Reinhard and Sonderaktion 1005. Many others escaped conviction, such as Ernst Lerch, Globočnik's deputy and chief of his Main Office, whose case was dropped for lack of witness testimony.

- The Treblinka and Sobibor death camps were built in roughly the same timeframe. During the construction of the gas chambers at Sobibor SS-Scharführer Erich Fuchs installed a 200 horsepower, water cooled V-8 gasoline engine as the killing mechanism there, according to his own postwar testimony. Fuchs installed a similar engine at Treblinka as well. There's an ongoing debate with regard to the type of fuel at Treblinka used as the lethal agent. The chief argument for its identification as petrol (i.e., gasoline, or gas) comes directly from the eyewitness testimonies of insurgents who survived the Treblinka uprising. On 2 August 1943, they set ablaze a petrol tank causing it to explode. No second tank containing a different type of fuel (i.e., diesel) was ever mentioned in any known literature on the subject. All diesel motors require diesel fuel; the engine and the fuel work together as a system. An effort in the late '30s to extend the diesel engine's use to passenger cars was interrupted by World War II. Therefore, the cars driven by the SS at Trebinka (see Rajzman 1945 at U.S. Congress, and Ząbecki's court testimonies at Düsseldorf) could not have been fueled by diesel, and neither was the killing apparatus without a second fuel tank on premises.

- Auschwitz-Birkenau Museum (23 December 2005). ""Majdanek Victims Enumerated" by Paweł P. Reszka". Lublin scholar Tomasz Kranz established a new figure which the Majdanek museum staff considers reliable. Earlier calculations were greater: c. 360,000, in a much-cited 1948 publication by Judge Zdzisław Łukaszkiewicz of the Main Commission for the Investigation of Nazi Crimes in Poland; and c. 235,000 in a 1992 article by Dr. Czeslaw Rajca, formerly of the Majdanek Museum. However, the number of Majdanek victims, whose deaths the camp administration did not register, remains unknown although it might be considered significant.
