(starting Feb 2023) "It was in a forest north-east of Warsaw, 4 km (2.5 mi) south of the village of Treblinka in what is now the Masovian Voivodeship. The camp operated between 23 July 1942 and 19 October 1943 as part of Operation Reinhard, the deadliest phase of the Final Solution." is sourced to this source which is a primary source account of an eyewitness ... and does not support all of the information anyway.
"Managed by the German SS with assistance from Trawniki guards – recruited from among Soviet POWs to serve with the Germans – the camp consisted of two separate units." is sourced to this source pages 52, 77, 79, 80 which supports the composition of the Trawniki guards but nothing else in this sentence.
"Treblinka I was a forced-labour camp (Arbeitslager) whose prisoners worked in the gravel pit or irrigation area and in the forest, where they cut wood to fuel the cremation pits." is sourced to this source but that page is discussing the extermination camp (Treblinka II), not the labor camp Treblinka I.
"Between 1941 and 1944, more than half of its 20,000 inmates were murdered via shootings, hunger, disease and mistreatment." is sourced to this source pp. 160-161 and this source The first source is once more about the extermination camp, and the second only supports the deaths were from "of which half died or were shot"
"Gassing operations at Treblinka II ended in October 1943 following a revolt by the prisoners in early August. Several Trawniki guards were killed and 200 prisoners escaped from the camp;" is sourced to this source and this source but Arad's The Operation Reinhard Death Camps (2018 updated edition) p. 347 gives the estimated total prisoners who got past the fences and escaped as between 350 and 400. The number of escapees who were still free 24 hours after the escape is given as about 200. Arad's numbers should at least be mentioned - rather than relying on two non-academic accounts for lower numbers, and ideally we'd use the academic numbers, not the non-academic ones at all.
"almost a hundred survived the subsequent pursuit." is sourced to this BBC source and this source pp. 8-9 (and what IS this source - an extract from a book? Who is the author?) but the second source doesn't support the statement either (at least according to my google translate rough translation)
"The camp was dismantled in late 1943. A farmhouse for a watchman was built on the site and the ground ploughed over in an attempt to hide the evidence of genocide." is sourced to this source but Grossman's a primary account of the discovery of the camp - not a good source for this information.
"In the postwar Polish People's Republic, the government bought most of the land where the camp had stood, and built a large stone memorial there between 1959 and 1962. In 1964, Treblinka was declared a national monument of Jewish martyrdom[b] in a ceremony at the site of the former gas chambers." is sourced to this source p. 122 which, besides not being a very good source if its even reliable, does not support anything but the 1964 ceremony (and it doesn't call it a national museum of Jewish martyrdom either)
"Following the invasion of Poland in 1939, most of the 3.5 million Polish Jews were rounded up and confined to newly established ghettos by the Nazis. The system was intended to isolate the Jews from the outside world in order to facilitate their exploitation and abuse." is sourced to this source but that doesn't support the information - it's specifically talking about Lodz and no where is the figure of 3.5 million mentioned. Trunk also says that the isolation was intended to prevent outside aid...
"In 1941, the initial victories of the Wehrmacht[c] over the Soviet Union inspired plans for the German colonisation of occupied Poland, including all territory within the new district of General Government. At the Wannsee Conference held near Berlin on 20 January 1942, new plans were outlined for the genocide of Jews, known as the "Final Solution" to the Jewish Question." is sourced to this source which does not support the first sentence at all.
"The extermination programme was codenamed Operation Reinhard.[d] and was separate from the Einsatzgruppen mass-murder operations in Eastern Europe, in which half a million Jews had already been murdered." is sourced to this source but that only supports the half-million death toll til the end of 1941. (NOte that Operation Reinhard wasn't named until after the death of Heydrich in May 1942 (although it was put into action long before its naming as Reinhard), so the statement "already been murdered" is a bit ambiguous)
"All three were equipped with gas chambers disguised as shower rooms, for the murder of entire transports of people. The method was established following a pilot project of mobile extermination conducted at Soldau and at Chełmno extermination camp that began operating in 1941 and used gas vans. Chełmno (German: Kulmhof) was a testing ground for the establishment of faster methods of murdering and incinerating bodies." is sourced to (apparantly) this source which does not support the information at all beyond the "Chelmno was a testing ground" It was mostly added (with the wrong source) in [Special:Diff/670987742 this 2015 edit]
"Alongside the Reinhard camps, mass-murder facilities using Zyklon B were developed at the Majdanek concentration camp in March 1942" is sourced to this source which does not support the information (Majdanek is only mentioned once in the source and that is in connection with the Operation Harvestfest)
"The Operation Reinhard camps reported directly to Himmler." is sourced to the judgement in the Eichman trial - which is a primary source. And this sentence also contradicts the previous sentence - which stated that Globocnik was in charge of the Reinhard camps.
"The staff of Operation Reinhard, most of whom had been involved in the Action T4 "involuntary euthanasia" programme," is sourced to this source pp. 684 686 but the source here only has 580 or so pages.
"Most of the Jews who were murdered in the Reinhard camps came from ghettos." is sourced to Evans The Third Reich at War p. 306] but the source says "... went through the transitional stage of confinement in a ghetto.. all the Jews who were killed in the Reinhard Action camps."
"The Operation Reinhard camps reported directly to Himmler, and not to the concentration camps inspector Richard Glücks." minor quibble but this is repetition of an earlier sentence which was noted above as being contradicted by another sentence that said Globnocnik was the overseer of the camp
"Before World War II, it was the location of a gravel mining enterprise for the production of concrete, connected to most of the major cities in central Poland by the Małkinia–Sokołów Podlaski railway junction and the Treblinka village station. The mine was owned and operated by the Polish industrialist Marian Łopuszyński, who added the new 6 km (3.7 mi) railway track to the existing line." this is an editorial thing - but much of this is sourced to a marginal source (at best!) and really doesn't add much to the knowledge of the camp.
"When the German SS took over Treblinka I, the quarry was already equipped with heavy machinery that was ready to use." is sourced to a primary source - a deposition, which does not even support the information ... it's purely concerned with Treblinka II and only mentions Treblinka I in passing without anything more than "The Treblinka camp is divided into two parts: Camp no. 1, or as the prisoners called it, the "death camp", and the worker's camp, called Camp no. 2. The camps were situated at a distance of some 2-3 km from each other"
"halfway between some of the largest Jewish ghettos in Nazi-occupied Europe, including the Warsaw Ghetto and the Białystok Ghetto, the capital of the newly formed Bialystok District. The Warsaw Ghetto had 500,000 Jewish inmates" is sourced to this source p. 657 but it does not support the information (Bialystok is not even mentioned in the article)
"Between 1942 and 1943, the extermination centre was further redeveloped with a crawler excavator. New gas chambers constructed of brick and cement mortar were freshly erected, and mass cremation pyres were also introduced." is sourced to this source which is borderline reliable...
"The perimeter was enlarged to provide a buffer zone, making it impossible to approach the camp from the outside. The number of trains caused panic among the residents of nearby settlements." is sourced to this source which is a TV documentary transcript. It does not support the information
"They would likely have been killed if caught near the railway tracks" is sourced to Kopówka & Rytel-Andrianik p. 405 which google translate tells me is a personal account that does not support this information.
"Opened on 1 September 1941 as a forced-labour camp (Arbeitslager)," is sourced to Kopówka & Rytel-Andrianik page 74 which is supported but is a close paraphrase of this marginal source - the source says "opened on 1 September 1941 as a forced labour camp"
"Treblinka I replaced an ad hoc company established in June 1941 by Sturmbannführer Ernst Gramss. A new barracks and barbed wire fencing 2 m (6 ft 7 in) high were erected in late 1941." is sourced to Kopówka & Rytel-Andrianik p. 36 which does not support the information from this marginal source.
"To obtain the workforce for Treblinka I, civilians were sent to the camp en masse for real or imagined offences, and sentenced to hard labour by the Gestapo office in Sokołów, which was headed by Gramss." is sourced to Kopówka & Rytel-Andrianik pp. 49, 55 which does not support the information.
"The average length of a sentence was six months, but many prisoners had their sentences extended indefinitely. Twenty thousand people passed through Treblinka I during its three-year existence. About half of them were murdered there via exhaustion, hunger and disease." is sourced to Kopówka & Rytel-Andrianik p 74 which does not support the first sentence nor the "via exhaustion, hunger, and disease" part.
"Those who survived were released after serving their sentences; these were generally Poles from nearby villages." is sourced to Kopówka & Rytel-Andrianik pp. 368-369, 380 which is a personal account of one of the prisoners, and doesn't support the information either.
"At any given time, Treblinka I had a workforce of 1,000–2,000 prisoners," is sourced to Kopówka & Rytel-Andrianik p. 36 which does not support the information
"most of whom worked 12- to 14-hour shifts in the large quarry and later also harvested wood from the nearby forest as fuel for the open-air crematoria in Treblinka II." is sourced to this marginal webpage which does not support the information
"During its entire operation, Treblinka I's commandant was Sturmbannführer Theodor van Eupen." is sourced to Kopówka & Rytel-Andrianik pp. 36 which says that the commandant of the camp at the time it was built was Eupen, but does not support the statement that he was commandant the whole time.
"He ran the camp with several SS men and almost 100 Hiwi guards. The quarry, spread over an area of 17 ha (42 acres), supplied road construction material for German military use and was part of the strategic road-building programme in the war with the Soviet Union. It was equipped with a mechanical digger for shared use by both Treblinka I and II. Eupen worked closely with the SS and German police commanders in Warsaw during the deportation of Jews in early 1943 and had prisoners brought to him from the Warsaw Ghetto for the necessary replacements. According to Franciszek Ząbecki, the local station master, Eupen often murdered prisoners by "taking shots at them, as if they were partridges". A widely feared overseer was Untersturmführer Franz Schwarz, who executed prisoners with a pickaxe or hammer." is sourced to Kopówka & Rytel-Andrianik pp. 44, 74 which only supports the fact that Schwarz killled prisoners with a pickaxe or hammer.
"Treblinka II (officially the SS-Sonderkommando Treblinka) was divided into three parts: Camp 1 was the administrative compound where the guards lived, Camp 2 was the receiving area where incoming transports of prisoners were offloaded, and Camp 3 was the location of the gas chambers.[g] All three parts were built by two groups of German Jews recently expelled from Berlin and Hanover and imprisoned at the Warsaw Ghetto (a total of 238 men from 17 to 35 years of age)." is sourced to Kopówka & Rytel-Andrianik p 77, chapt. 3:1 which has some issues - it does support that the number of German Jews that constructed the camp were 238 men, but it only specifies the ages for the first group of 160 - the second group of 78 is not given an age range nor is it mentioned that they came from Hanover - it only specifies Berlin and only for the first 160. It does support the official name, but does not specifically support the "three camps" or their names nor the other information. Note that a second source is also attached from here but this is classic WP:SYNTH as this second source is about the diary of Adam Czerniakow in Warsaw and says that "5 April 1942 – At 8am 1,025 expellees from Berlin came. Mainly older people, partly intelligentsia. Many women." which I assume is supposed to tie this group mentioned in Czerniakow's diary to the group of German Jews that on 10 April 1942 began construction in Treblinka - but neither source ties this information together so the article is doing SYNTH by placing this second source with this information. Also note that other sources divide the camp differently - this marginal source (but used in the wikipedia article, so if it's used for other stuff, it's viewpoint on the division of the camp should have also been used) says that there were five (or maybe six) divisions - "The camp was divided into zones of nearly equal size - the SS and Ukrainian living area, the Auffanglager (the reception area), a great sorting barracks (the Wohnlager), the Jewish living and working quarters, and the Totenlager, also known as the upper camp. A 100m by 100m square was separated from the rest of the camp by a barbed wire fence. It contained three barracks forming a “U” shape. Here the Jewish prisoners who worked in the lower camp spent their nights. At the far side of the roll-call area of this section was the latrine, covered by a straw roof."
"or 13.5 ha (33 acres) in size (sources vary)" is sourced to this website which appears to be reprinting a ... travel guidebook to the region?
"The first section of Treblinka II (Camp 1) was the Wohnlager administrative and residential compound; it had a telephone line. The main road within the camp was paved and named Seidel Straße[h] after Unterscharführer Kurt Seidel, the SS corporal who supervised its construction. A few side roads were lined with gravel. The main gate for road traffic was erected on the north side." is sourced to Kopówka & Rytel-Andrianik pp. 79-80 which does not support the information - (much of which is trivia - "A few side roads were lined with gravel." is like ... so trivial for a mention about a camp that executed almost a million people!) ... the source says (via google translate) "In this part of the camp, there were barracks for prisoners, referred to as the ghetto, camp No. 1 or the lower camp. The Germans called it Wohnlager – a residential camp"
"Behind a second fence, about 100 m (330 ft) from the track, there were two large barracks used for undressing, with a cashier's booth where money and jewelry were collected, ostensibly for safekeeping. Jews who resisted were taken away or beaten to death by the guards. The area where the women and children were shorn of their hair was on the other side of the path from the men. All buildings in the lower camp, including the barber barracks, contained the piled up clothing and belongings of the prisoners." is sourced to Kopówka & Rytel-Andrianik p. 100 which does not support any of this information (there's a mention of sign that says valuables would need to be deposited at a counter but nothing about a booth)
"Directly behind the "Lazaret" shack, there was an open excavation pit seven metres (23 ft) deep. These prisoners were led to the edge of the pit[75] and shot one at a time by Blockführer Willi Mentz, nicknamed "Frankenstein" by the inmates." is sourced to Kopówka & Rytel-Andrianik p. 100 which does not support the information (It names the shooter at the Lazaret as Unterscharfuhrer Miete, not Mentz)
"Mentz single-handedly executed thousands of Jews," is sourced to this website which is of marginal reliablity
"The third section of Treblinka II (Camp 3, also called the upper camp) was the main killing zone, with gas chambers at its centre." is sourced to Kopówka & Rytel-Andrianik p. 82 which does not state this was called "camp 3" (it calls it camp 2) and that the gas chambers were at the centre of this section
"It was completely screened from the railway tracks by an earth bank built with the help of a mechanical digger. This mound was elongated in shape, similar to a retaining wall, and can be seen in a sketch produced during the 1967 trial of Treblinka II commandant Franz Stangl. On the other sides, the zone was camouflaged from new arrivals like the rest of the camp, using tree branches woven into barbed wire fences by the Tarnungskommando (the work detail led out to collect them)." is sourced to Kopówka & Rytel-Andrianik p. 89 and this marginally reliable source. Kopowka supports the last sentence but not the first two, and the website supports that there was a mound around the extermination area, but not any of the other details in the first two sentences.
"From the undressing barracks, a fenced-off path led through the forested area to the gas chambers." is sourced to Kopówka & Rytel-Andrianik p. 82 which does not support the information
"The SS cynically called it die Himmelstraße ("the road to heaven")" is sourced to a primary source - Treblinka Survivor
"For the first eight months of the camp's operation, the excavator was used to dig burial ditches on both sides of the gas chambers; these ditches were 50 m (160 ft) long, 25 m (82 ft) wide, and 10 m (33 ft) deep." is sourced to this marginally reliable website which does not support the "for the first 8 months" and the source also only says of the ditches that a "number of these ditches were approximately 50m long, 25m wide, and 10m deep" ... not that all of them were exactly that size.
"In early 1943, they were replaced with cremation pyres up to 30 m (98 ft) long, with rails laid across the pits on concrete blocks. The 300 prisoners who operated the upper camp lived in separate barracks behind the gas chambers." is sourced to Kopówka & Rytel-Andrianik p. 84 which does not totally support the first sentence here - the source does not say that the rails were laid across the pits on concrete blocks, merely that the rails were supported by concrete bases - it does not say that these rails were over the original burial pits.
"Unlike Nazi concentration camps in which prisoners were used as forced labour, extermination camps such as Treblinka had only one function: to murder those sent there. To prevent incoming victims from realising its nature, Treblinka II was disguised as a transit camp for deportations further east, complete with unreal train schedules, a fake train-station clock with hands painted on it, names of destinations," is sourced to this marginal website which supports the second sentence, but not the first.
"a fake ticket window, and the sign "Ober Majdan"" is sourced to Grossman's "Treblinka Hell" p. 379 but this source does not call the "ticket window" fake (the source says the train station was real with actual waiting rooms and a baggage room) nor does it mention a sign to "Ober Majdan".
"a code word for Treblinka commonly used to deceive prisoners arriving from Western Europe. Majdan was a prewar landed estate 5 km (3.1 mi) away from the camp." is sourced to Kopówka & Rytel-Andrianik p. 81 which does not support the information
"The mass deportation of Jews from the Warsaw Ghetto began on 22 July 1942 with the first transportation of 6,000 people. The gas chambers began to be operated the following morning." is sourced to Kopówka & Rytel-Andrianik p. 94 which does not support the information
"For the next two months, deportations from Warsaw continued daily, via two shuttle trains (the second one, from 6 August 1942)" is sourced to Kopówka & Rytel-Andrianik p. 92 does not support this information - the daily part is not covered (the source states that the Germans ORDERED daily transports, not that they happened) and only that the second train was a "shuttle train" (google translate on that...)
"each carrying about 4,000 to 7,000 people crying for water. No other trains were allowed to stop at the Treblinka station." is sourced to Kopówka & Rytel-Andrianik p. 98 which states (via Google translate) "From September 1, 1942, it was forbidden to stop passenger trains and sell tickets at the railway station." which doesn't quite support this information in the wiki article
"The first daily trains came in the early morning, often after an overnight wait, and the second, in mid-afternoon." is sourced to Kopówka & Rytel-Andrianik p. 94 which does not support the information (it does mention one survivor's account of waiting overnight at the Malkinia stop but this does not support the "often" wording - we can't make a general conclusion from one account and the rest of this isn't supported in the given source
"All new arrivals were sent immediately to the undressing area by the Bahnhofskommando squad that managed the arrival platform, and from there to the gas chambers. According to German records, including the official report by SS-Brigadeführer Jürgen Stroop, 265,000 Jews were transported in freight trains from the Warsaw Ghetto to Treblinka during the period from 22 July to 12 September 1942." is sourced to this USHMM source about the Warsaw Ghetto Uprising and this trial judgement from 1965. This is a synthesis of the two sources - the USHMM says that the Germans deported around 265,000 Jews from Warsaw from 22 July to 12 Sept 1942 but does not mention the Stroop Report in connection with this number. The trial judgement says "According to the Stroop report a total of approximately 310,000 Jews were transported in freight trains from the Warsaw ghetto to Treblinka during the period from July 22, 1942 to October 3, 1942." but our article combines the two sources to create a synthesis.
"The Polish railway was very heavily used. An average of 420 German military trains were passing through every 24 hours on top of internal traffic already in 1941." is sourced to this source - which, first, is a website that I can't see as even reliable, much less of high quality. Second, the source says that this is for the entirety of Poland before the attack on the Soviet Union - which predates the opening of Treblinka by an entire year.
"The Holocaust trains passage to their destination was routinely delayed; some transports took many days to arrive." is sourced to Kopówka & Rytel-Andrianik p. 95 which is sourced to one survivor's account of his journey - and just says "two days and one night" for the journey.
"Hundreds of prisoners were murdered by exhaustion, suffocation and thirst while in transit to the camp in the overcrowded wagons." is sourced to Friedlander 2009 p. 432 which does not quite support this - it's based on Stangel's own testimony and is describing one specific incident when he visited while Eberl was in charge early in the history of the camp... we can't extrapolate from this primary account to a general conclusion
"In extreme cases, such as the Biała Podlaska transport of 6,000 Jews travelling only a 125 km (78 mi) distance, up to 90 percent of people were already dead when the sealed doors were opened." is sourced to Kopówka & Rytel-Andrianik p. 95 which does not mention the distance traveled (a minor quibble is that the wiki article says "the Biala Podlaska transport" but the source says "a transport from ..."
"From September 1942 on, both Polish and foreign Jews were greeted with a brief verbal announcement. An earlier signboard with directions was removed because it was clearly insufficient." is sourced to this USHMM source which does not support this information at all - none of it.
"The deportees were told that they had arrived at a transit point on the way to Ukraine and needed to shower and have their clothes disinfected before receiving work uniforms and new orders." is sourced to Klee p. 246 which does not support this level of detail - the source itself (which is an account by Willi Mentz) says that the deportees were told "something to the effect that they were a resettlement transport, that they would be given a bath and that they would receive new clothes."
Note that this section on Polish Jews deported to Treblinka only says that Jews came from the Warsaw Ghetto and only gives a number of Polish Jews killed as that 265,000 number. But ... Arad in The Operation Reinhard Death Camps: Belzec, Sobibor, Treblinka (2018 revised and updated edition) on pp. 455-461 gives approximate numbers of Jews deported to Treblinka from Polish areas as at least 749,000. Note that this breakdown does not include victims from other areas - just from the three Polish districts of Warsaw, Radom, and Lublin. The lack of inclusion of the bigger numbers gives the impression that the killing that took place was not as extensive. This doesn't include the 110,000 to 127,000 Jews from the Bialystok District
"They had train tickets and arrived predominantly in passenger carriages with considerable luggage, travel foods and drinks, all of which were taken by the SS to the food storage barracks. The provisions included such items as smoked mutton, speciality breads, wine, cheese, fruit, tea, coffee, and sweets." is sourced to a primary source - Wiernik's testimony in 1945. (And it's .. trivia - why is this mentioned?)
"Treblinka was mainly used for the murder of Polish Jews, Bełżec was used to murder Jews from Austria and the Sudetenland, and Sobibór was used to murder Jews from France and the Netherlands. Auschwitz-Birkenau was used to murder Jews from almost every other country in Europe." is sourced to this USHMM source which does NOT support the information given - the source says "Belzec: The principal victims at Belzec were Jews from southern and southeastern Poland. Also among the victims were Jews deported from the so-called Greater German Reich to the Lublin District between October 1941 and the end of summer 1942. The Greater German Reich included Germany, Austria, the Sudetenland, and the Protectorate of Bohemia and Moravia. Sobibor: Most Jews deported to Sobibor came from the Lublin District. German authorities also transported French and Dutch Jews to Sobibor in spring and summer 1943. In late summer 1943, they deported small groups of Soviet Jews from Belarusian [Belorussian] and Lithuanian ghettos. Treblinka II: German officials transported the Jews from the Warsaw and Radom districts of the General Government View This Term in the Glossary to Treblinka II, where SS and police officials murdered them. Jews from the Bialystok administrative district were also deported there. Chelmo: German authorities deported most of the Jewish residents of the Lodz ghetto to Chelmno between January 1942 and spring 1943, and then in early summer 1944. The ghetto's surviving Roma and Sinti (so-called "Gypsy") residents were also deported there during that time. Auschwitz-Berkenau: In 1943 and 1944, the Auschwitz-Birkenau killing center played a significant role in the German plan to kill the European Jews. Beginning in late winter 1943, trains arrived at Auschwitz-Birkenau on a regular basis. These trains carried Jews from virtually every German-occupied country of Europe—from as far north as Norway to the Greek island of Rhodes off the coast of Turkey in the south, from the French slopes of the Pyrenees in the west to the easternmost reaches of German-occupied Poland and the Baltic states." ... the wiki article is a severe distortion of this source.
"The decoupled locomotive went back to the Treblinka station or to the layover yard in Małkinia for the next load," is sourced to Kopówka & Rytel-Andrianik p. 95 which does not support this information
"while the victims were pulled from the carriages onto the platform by Kommando Blau, one of the Jewish work details forced to assist the Germans at the camp." is sourced to Klee p. 246 which does not support the information
"They were separated by gender behind the gate; women were pushed into the undressing barracks and barber on the left, and men were sent to the right. All were ordered to tie their shoes together and strip. Some kept their own towels." is sourced to a primary source - Wiernik's testimony
"The Jews who resisted were taken to the "Lazaret", also called the "Red Cross infirmary", and shot behind it. Women had their hair cut off; therefore, it took longer to prepare them for the gas chambers than men." is sourced to this primary source
"The hair was used in the manufacture of socks for U-boat crews and hair-felt footwear for the Deutsche Reichsbahn." is sourced to Concentration Camp Dachau p. 137 plate 282 which supports that hair from Dachau and other concentratoin camps was used for felt slippers/etc but it is not specific to Treblinka so we can't assume this applied to Treblinka's hair - we need a source saying this is for Treblinka because the Operation Reinhard camps were not under the control of the concentration camp authorities, but under a different adminstration.
"Most of those murdered at Treblinka were Jews, but about 2,000 Romani people were also murdered there. Like the Jews, the Romani were first rounded up and sent to the ghettos. At a conference on 30 January 1940 it was decided that all 30,000 Romani living in Germany proper were to be deported to former Polish territory. Most of these were sent to Jewish ghettos in the General Government, such as those in Warsaw and Łódź. As with the Jews, most Romani who went to Treblinka were murdered in the gas chambers, although some were shot. The majority of the Jews living in ghettos were sent to Bełżec, Sobibór, or Treblinka to be murdered; most of the Romani living in the ghettos were shot on the spot. There were no known Romani escapees or survivors from Treblinka." is sourced to this journal article pp. 380-381 mostly supports this information but the last sentence is unsupported.
"After undressing, newly arrived Jews were beaten with whips to drive them towards the gas chambers; hesitant men were treated particularly brutally. Rudolf Höss, the commandant at Auschwitz, contrasted the practice at Treblinka of deceiving the victims about the showers with his own camp's practice of telling them they had to go through a "delousing" process." is sourced to Shirer p. 969 (a marginal source at best, and seriously outdated) and Hoss' own testimony (which is a primary source). Shirer discusses Auschwitz, but he only mentions Treblinka six times in this edition and none discusses how things were carried out at Treblinka other than when Hoss mentions that things were done better at Auschwitz.
"According to the postwar testimony of some SS officers, men were always gassed first, while women and children waited outside the gas chambers for their turn. During this time, the women and children could hear the sounds of suffering from inside the chambers, and they became aware of what awaited them, which caused panic, distress, and even involuntary defecation." is sourced to "Lanzmann 1985" which is utterly unhelpful - as Lanzman's documentary Shoah is over 9 hours long!
"Many survivors of the Treblinka camp testified that an officer known as 'Ivan the Terrible' was responsible for operating the gas chambers in 1942 and 1943. While Jews were awaiting their fate outside the gas chambers, Ivan the Terrible allegedly tortured, beat, and murdered many of them. Survivors witnessed Ivan beat victims' heads open with a pipe, cut victims with a sword or a bayonet, cut off noses and ears, and gouge out eyes." is sourced to a primary source - the US extradition court files
"One survivor testified that Ivan murdered an infant by bashing it against a wall;" is sourced to this news story - not a good source
"another claimed that he raped a young girl before cutting her abdomen open and letting her bleed to death." is sourced to L'Chaim: the exceptional life of Chaim Sztajer is sourced to a book held by TWO libraries world wide
"The gas chambers were completely enclosed by a high wooden fence. Originally, they consisted of three interconnected barracks 8 m (26 ft) long and 4 m (13 ft) wide, disguised as showers. They had double walls insulated by earth packed down in between. The interior walls and ceilings were lined with roofing paper. The floors were covered with tin-plated sheet metal, the same material used for the roof. Solid wooden doors were insulated with rubber and bolted from the outside by heavy cross-bars" is sourced to Kopówka & Rytel-Andrianik p. 82 which doesn't quite support this detailed description - because it says "There is no exact information about them. Most likely they looked like in Belzec." and then goes on to give a description which appears to be based off the gas chambers at Belzec. Nor does the source given support the "disguised as showers" or the fence around them.
"After the new gas chambers were built, the duration of the killing process was reduced to an hour and a half." is sourced to this marginal source which does not support this as the source says "Later the Germans "gained experience" and reduced the duration of the killing process to an hour and a half." and does not tie this increased "efficiency" to the new gas chambers
"The victims were murdered via gas, using the exhaust fumes conducted through pipes from an engine of a Red Army tank." is sourced to this source which frankly contradicts our statement that it was from a "Red Army tank" - the source just says that "according to the story of the German machine operator, was of Russian make"
"The engine was brought in by the SS at the time of the camp's construction and housed in a room with a generator that supplied the camp with electricity." is sourced to Kopówka & Rytel-Andrianik p. 82 which supports the second part "housed in a room ..." but not the first part
"trains that arrived later in the day had to wait on layover tracks overnight at Treblinka, Małkinia, or Wólka Okrąglik" is sourced to Kopówka & Rytel-Andrianik p. 98 which supports that sometimes trains waited at Wolka Okraglik but not the other locations and doesn't support overnight stays for any of the three stations
"Between August and September 1942, a large new building with a concrete foundation was built from bricks and mortar under the guidance of Action T4 euthanasia expert Erwin Lambert. It contained 8–10 gas chambers, each of which was 8 by 4 m (26 by 13 ft), and it had a corridor in the centre. Stangl supervised its construction and brought in building materials from the nearby village of Małkinia by dismantling factory stock" is sourced to Kopówka & Rytel-Andrianik p. 82 which does not support the information - the description of the gas chamber building on p. 82 is referring to the original gas chambers
"During this time victims continued to arrive daily and were led naked past the building site to the original gas chambers" is sourced to this Yad Vashem source which does not support the fullness of our statement - it supports that the old gas chambers continued to be used, but not the "led naked past the building site to the original gas chambers" bit
"The new gas chambers became operational after five weeks of construction, equipped with two fume-producing engines instead of one." is sourced to Kopówka & Rytel-Andrianik p. 84 which does not support the length of construction time, but does say that there were "two diesel engines"!
