Overview and Historiography of Aktion Reinhard
Between March 1942 and October 1943, nearly 1.4 million Jews were deported to the camps of Belzec, Sobibor and Treblinka. The camps were operated under the auspices of the SS and Police Leader (SS- und Polizeiführer, SSPF) Lublin, Odilo Globocnik, and used the codename ‘Einsatz Reinhardt’ or ‘Aktion Reinhard’. German SS men along with companies of Ukrainian auxiliaries trained at the Trawniki camp manned the camps in detachments designated ‘SS-Sonderkommando’. The majority of the German staff had previously served in six euthanasia ‘institutes’ in Germany as part of the T4 organisation named after its headquarters on Tiergartenstrasse 4 in Berlin. There they had helped murder 70,000 ‘incurable’ psychiatric patients using carbon monoxide gas dispensed from cylinders, and to cremate the bodies.
The overwhelming majority of the 1.4 million Jewish deportees to the Aktion Reinhard camps died either en route or immediately after arrival, victims of the Nazi ‘Final Solution of the Jewish Question’. A tiny percentage were selected after arrival for forced labour either in the three camps or, more rarely, in nearby labour camps, work which the majority did not survive. A significant number of the deportees died en route while still on the trains from asphyxiation or exhaustion. Many more were shot immediately after arrival for resisting or because they were deemed too weak to walk towards the main killing method at the three camps, gas chambers into which carbon monoxide-laden engine exhaust fumes were piped. At first, the corpses of the victims – from whatever cause – were dragged to mass graves by the Jewish slave labourers who had been temporarily spared execution and buried there; later on, the decomposed and decomposing bodies were exhumed and burned on large open-air pyres along with the corpses of newly arrived victims. In two of the three camps, the slave labourers successfully revolted, breaking out of Treblinka in August 1943 and Sobibor in October 1943.
Most of the victims of Aktion Reinhard were Polish Jews from the Warsaw, Radom, Cracow, Lublin and Galicia districts of the Generalgouvernement as well as the Zichenau and Bialystok districts annexed into Germany proper. But transports arrived directly or indirectly at Belzec, Sobibor and Treblinka from Germany, Austria, the so-called ‘Protectorate’ of Bohemia-Moravia (today’s Czech Republic), Slovakia, the Yugoslavian region of Macedonia, the Greek region of Thrace, France, the Netherlands, Lithuania and Belorussia. Virtually none survived. Precisely two out of 17,004 Jews deported from Theresienstadt to Treblinka in the autumn of 1942 were alive at the time of liberation. Among those who did not survive were three of Sigmund Freud’s sisters. Of the 34,313 Jews deported from the Netherlands to Sobibor in the spring and early summer of 1943, just 18 survived the war.
How do we know all this? How did we come to know about Belzec, Sobibor and Treblinka? A short answer to this question would go something like this: during the war, reports began to appear within a month of the opening of Belzec that large numbers of Jews were entering the camp and not coming out. A growing number of reports reaching the Polish underground state, the Delegatura, as well as Jewish organizations such as the Oneg Shabes archive in Warsaw, led virtually all within Poland quickly to conclude that Belzec, Sobibor and Treblinka were sites of extermination. Hearsay rumours of the use of electricity and steam circulated among the Polish and Jewish population of Poland as well as among German occupation officials and troops, but the majority of the reports in Poland converged on the use of gas chambers. Eyewitness accounts were written at the time by a small number of escaped prisoners. The news was communicated in partially distorted form to the outside world. Reports of Belzec and Sobibor reached London along with reports on the Chelmno extermination camp in the annexed territory of the Warthegau, in June 1942. A further crucial report, combining information compiled by Oneg Shabes with Polish underground sources, was brought out by the Polish underground courier Jan Karski in November 1942, and together with other evidence from other regions of Nazi-occupied Europe, led the Allies to issue a declaration in December 1942 condemning the Nazi extermination of the Jews. Further reports leaked out via exchanges of citizens of Mandate Palestine with interned Germans, Slovakia, Sweden and into Germany. By 1943, the Polish underground was tracking the course of the extermination campaign as well as the cover-up attempts of the Nazis at the camps very closely. Wartime publications outside Nazi-occupied Europe reprinted some of the most crucial early reports, complete with inaccuracies such as misidentifying gas chambers as steam chambers, while other publications, based on more recent reports without the distortion of wartime hearsay and Chinese whispers, spoke of gas chambers, and newspapers reprinted testimonies from Treblinka escapees offering a detailed account of the extermination process.
In the summer of 1944, the sites of the three camps were overrun in the Soviet summer offensive, and survivors began to come out of hiding, joining nearby villagers who had observed the killing and burning on their doorsteps in giving testimonies and statements to Polish and Soviet investigators as well as Polish and Soviet journalists; these recipients were soon joined by the Central Jewish Historical Commission of Poland, which took down further testimonies and also began the process of historical research by sifting through captured German documents as well as publishing memoirs, narrative accounts and studies in Polish and Yiddish. The sites – which rapidly resembled moonscapes due to grave-robbing by peasants and others searching for imaginary ‘Jewish gold’ – were inspected in 1944 by the Soviets and examined in greater detail by investigators of the Polish Main Commission in the autumn of 1945. Enormous quantities of ash from cremains as well as other body parts littered the sites, which stank according to visitors who recorded their impressions at the time. Utilising eyewitness testimonies, the physical inspections and investigations of the condition of the sites and a certain number of captured German documents, the Polish Main Commission concluded that Belzec, Sobibor and Treblinka had been extermination camps and estimated the number of victims at 1,631,000 (Belzec: 600,000; Sobibor: 250,000; Treblinka: 781,000), rejecting earlier overestimates from disoriented survivors that ranged up to 2 or 3 million per camp. The evidence gathered was then used in certain trials of Nazi officials extradited to postwar Poland. For example the Treblinka investigation was submitted in toto at the trial of Ludwig Fischer, the governor of the Warsaw district.
At the same time as investigations in Poland were under way, eyewitnesses began to give testimonies in Western Europe, some from survivors and some from SS men who had visited the camps or knew of their purpose. German documentary evidence, not least from the official diary of Hans Frank’s Generalgouvernement administration, was examined and conclusively proved that Nazi policy towards Polish Jews was one of extermination, leaving only a minority alive temporarily as slave labourers. The International Military Tribunal at Nuremberg as well as the successor Doctors’ Trial and Oswald Pohl Trial collectively uncovered the evidence of the T4-Aktion Reinhard connection, the involvement of the SS Economic and Administration Main Office (Wirtschafts- und Verwaltungshauptamt, WVHA) in the processing of plunder as well as the role of Odilo Globocnik in directing Aktion Reinhard. The Dutch Red Cross launched a systematic investigation of the fate of the 34,313 Dutch Jews deported to Sobibor, based on the records of the Westerbork transit camp in the Netherlands and the testimonies of the 18 survivors. Dutch cooperation with the Polish Main Commission over Sobibor was close.
By the end of the 1940s, the evidence for extermination at the Aktion Reinhard Camps was sufficiently conclusive that they could be labeled a historical fact. However, only a fraction of the total evidence had hitherto come to light. Historians began the process of research, aided on the one hand by the publication of many documents and other sources from the 1940s trials, but hampered by lack of access to the full range of sources – as was universal in an era before anyone had thought of a Freedom of Information Act. Belzec, Sobibor and Treblinka were prominently discussed in all of the original pioneering overviews by Leon Poliakov, Gerald Reitlinger, Arthur Eisenbach and Raul Hilberg published from 1951 to 1961. Indeed, Eisenbach published the first short English-language overview of Aktion Reinhard in 1962. Outside the academy, survivors and members of the landsmanshaften of the erased Jewish communities of Poland began to compile so-called yizker bukher or memorial books, and a number of these memorial books contained the testimonies of Sobibor and Treblinka survivors, as well as copious detail on the deportations, and escapes from deportation trains.
In contrast to other Nazi camps, the staff of Aktion Reinhard was slow to be apprehended, not least because the camps were closed down and the personnel transferred to other duties long before the end of war, whereas concentration camp staff was generally captured in or near to concentration camps in the spring of 1945. Many, like Christian Wirth, the “inspector” of the three camps, had died during the war. Globocnik had committed suicide in 1945, and key subordinates such as Franz Stangl, the commandant of Sobibor and Treblinka, had assumed false identities and later fled to Latin America. Thus it was not until 1948-1950 that the first SS men who had served at Belzec, Sobibor and Treblinka were interrogated about their activities by detectives from the newly created state of West Germany, in the course of the judicial investigation of the T4 euthanasia program, and then put on trial. Their Ukrainian auxiliaries, however, had been apprehended and interrogated in ever increasing numbers by Soviet investigators starting in September 1944, but it was not until several decades later that these statements began to be made available in the West. In 1958, West Germany began to investigate Nazi crimes systematically through the Central Office of State Justice Administrations for the Investigation of National Socialist Crimes (Zentrale Stelle der Landesjustizverwaltungen zur Aufklärung nationalsocialistischer Verbrechen), and succeeded in apprehending a significant number of the Aktion Reinhard SS, prosecuting them in a series of trials in the 1960s while also investigating and prosecuting the crimes of other SS and Police commands that had been involved in the deportation side of Aktion Reinhard. The capture and trial of Adolf Eichmann prompted a further bout of publications of evidence of Nazi crimes, including the crimes of Aktion Reinhard, and saw a number of survivors of Sobibor and Treblinka give evidence during the trial.
At the same time, there were a series of trials of Trawniki men in the Soviet Union. From the 1970s, judicial investigations of Aktion Reinhard revolved almost entirely around the Trawniki men, with trials in West Germany of the commandant of Trawniki, Karl Streibel, as well as of a Trawniki man assigned to the Treblinka I labour camp. Trawnikis who had emigrated to the United States and Canada began to be investigated from the end of the 1970s, in the US under the auspices of the Office of Special Investigations, and in Canada by a unit of the Royal Canadian Mounted Police. These investigations benefited from increased cooperation between the Soviet Union, West Germany and North America, and led to denaturalization proceedings and the deportation of Nazis and their collaborators who had lied while immigrating. The most prominent case involved a Trawniki man, Ivan Demjanjuk, who was denaturalized and deported to Israel, which prosecuted him for his alleged role at Treblinka in 1987, convicting him and sentencing him to death. This sentence was overturned on appeal due to the emergence of new evidence and the realisation that this was a case of mistaken identity; Demjanjuk had not been “Ivan the Terrible” but had in fact been a guard at Sobibor. Returning to the US, Demjanjuk was again denaturalized and deported to Germany in 2009, where he was put on trial in 2010 and convicted in May 2011, almost certainly the last man to be tried for his involvement in Aktion Reinhard.
Our knowledge of Belzec, Sobibor and Treblinka does not, however, rest solely on judicial investigations. From the 1960s onwards, journalists, freelance writers and documentary film-makers portrayed these camps using classic journalistic methods, interviewing survivors and perpetrators. The first such journalistic account, by Jean-Francois Steiner, led to a major public controversy in France in the mid-1960s. Survivors of the camps also offered their own accounts, producing a series of memoirs and in some cases, engaging in their own historical research. Survivors were also responsible for editing two important collections of testimonies from Treblinka and Sobibor that appeared in 1979 and 1980 respectively. Kurt Gerstein, an SS officer who visited Belzec in August 1942 and witnessed a gassing, became a kind of icon in postwar West Germany due to the widespread dissemination of his eyewitness account and the ambiguity of his role as an SS officer responsible for supplying Auschwitz with Zyklon B but who also tried to spread the news of extermination.
From an even earlier stage, historians examined the Aktion Reinhard camps both in their own right and in the context of other aspects of the Holocaust. Documents were uncovered that had remained unknown to the earlier war crimes investigations; contemporary sources ranging from diaries and letters to the contents of Jewish underground archives, the intelligence reports of the Delegatura and Polish underground newspapers were edited and published. Some historians writing on Aktion Reinhard, like Wolfgang Scheffler, had served as an expert witness in the West German trials and produced no comprehensive overview. Others, like the Israeli historian Yitzhak Arad, a survivor of the Wilno ghetto and a sometime director of Yad Vashem, contributed essays and encyclopedia entries on the Aktion Reinhard camps and also produced the first comprehensive monograph of all three camps in 1987. In the 1980s, writers and historians such as Ernst Klee, Michael Burleigh and Henry Friedlander also explored the connection between the T4 euthanasia program and the Nazi Final Solution. A variety of brochures and short books from Polish and German authors and historians of varying calibres have appeared in recent decades. Amateur researchers such as Michael Tregenza as well as historians working largely outside the academy such as Robin O’Neil and Stephen Tyas have played a significant role in discovering new documents or researching camps such as Belzec, while the German private researcher Peter Witte has done important work on Sobibor and the surrounding context of Aktion Reinhard.
At the same time, professional historians have not remained idle, most notably in Poland, where earlier discussions at conferences of the 1980s have given way to a fairly systematic research effort. A major conference on ‘Aktion Reinhard’ was held in the German Historical Institute in Warsaw in 2002, with the proceedings published in both German and Polish in 2004, bringing together articles by Polish, German, Israeli and American historians on many aspects of Aktion Reinhard. By the 2000s, biographies and biographical essays on key perpetrators within Aktion Reinhard, including Odilo Globocnik, the first commandant of Treblinka, Irmfried Eberl, but also more junior SS men, were appearing. The publication of the camps encyclopedia Ort des Terrors in the late 2000s combined rather insubstantial entries based on secondary literature for Sobibor and Treblinka, written by the editors Barbara Distel and Wolfgang Benz, with a thorough description of Belzec written by the director of the Belzec Museum, Dr. Robert Kuwałek, whose monograph on Belzec appeared in Polish in late 2010. Kuwałek’s counterpart at the Sobibor Museum, Marek Bem, has recently edited a collection of testimonies in Polish, while Russian researchers have produced an oral history of the Sobibor revolt from accounts of Russian survivors. A series of articles on the Trawnikis have also appeared in academic journals and edited collections, including examinations of the cohort of Trawnikis at Belzec by Dieter Pohl as well as studies by David Rich and Peter Black, researchers who work or have worked for the OSI and its successor office within the US Department of Justice on Trawniki cases. Work has also been done on the memorialisation of the sites, research which has uncovered further information about the condition of the sites from 1944 to the erection of memorials from the 1960s onwards. Finally, in the late 1990s and 2000s, archaeologists, most notably Andrzej Kola, have examined the sites of Belzec and Sobibor and provided much more information than had been possible with 1940s techniques and the limited resources of devastated postwar Poland, especially on the size and shape of the mass graves, using techniques such as aerial photography and bore-probes. Further archaeological work is planned for Treblinka.
The question “how do we know about Belzec, Sobibor and Treblinka?” is thus answered: from a variety of investigations. Some have been legal, some have been what the Russians call “medico-legal”, i.e. forensic; some archaeological; some journalistic; many historical. Accumulating over time, our knowledge and understanding of the three camps – just as with any historical event – has deepened and been refined progressively. Moreover, this process will not stop any time soon. Quite aside from the prospect of further archaeological research, historians of the Holocaust are exceedingly unlikely to leave the subject of the Aktion Reinhard camps alone. The results of the past two decades of research, especially since the end of the Cold War and the opening up of archives in Eastern Europe, have accumulated faster than they can be synthesised into a single work. The time is ripe for a comprehensive monograph on the Aktion Reinhard camps, since our understanding of both the camps themselves as well as their context has changed considerably in the last quarter-century. One or more will undoubtedly be written within the next five to ten years. Bemoaning its absence today would be to commit the single-study fallacy, and to ignore how the exact same issue confronts virtually every topic. Research is ultimately no different to painting the proverbial Forth Bridge: as soon as you have completed one coat, you have to do it all over again.

 Gerstein’s testimony was published numerous times in the 1950s and 1960s, with an introduction by Hans Rothfels as ‘Augenzeugenbericht zu den Massenvergasungen’, VfZ 2, 1953, pp.177-194 and in the widely-disseminated brochure Dokumentation zur Massenvergasung, Bonn, 1962. For other examples of his iconic status in West Germany, see IfZ Zs 0326. His international fame was the result of Rolf Hochhuth’s controversial play Der Stellvertreter (The Deputy) in 1963.
