"Then the vehicle drives on for another 10 minutes, and by the time they reach the execution site, the occupants arrive already dead".

The Wehrmacht researcher Sergey Vershinin is currently publishing excerpts from the diary of Johannes Gutschmidt. Gutschmidt (1876-1961) was the commandant of various POW camps. Specifically the topic under the discussion was his time in Smolensk where he was the commandant of the Dulag-231.

In his diary Gutschmidt twice mentions a visit to the building of the Smolensk NKVD, or, more specifically, to the execution cellar where people used to be shot.

He attaches some valuable photos of the cellar. The second visit was on 07.04.1942:

7.4.42. Ganz früh rief mich Oberst Marschall an, ich sollte sofort das Nordlager auf Ausbaumöglichkeit erkunden. Ich fuhr mit Janusch um 8 ab und es zeigte sich, dass das Lager nicht zu gebrauchen ist. Der Oberst kam auch noch heraus und stimmte mir zu. Auf der Rückfahrt besichtigten wir die Hinrichtungszelle und die GPU Gefängniszellen, die jetzt von der Sicherungspolizei belegt sind. In jeder Zelle sassen 4 bis 6 Personen. Bei uns [handgeschrieben: i. e. bei der geheimen Feldpolizei] werden die Leute ebenfalls durch Pistolenschüsse ins Genick erschossen oder sie werden mit einem Gasauto heraus geschafft. Das hält vor der Stadt und schaltet die Auspuffgase so um, dass sie in das Innere des Wagens gelangen. Dann fährt der Wagen noch 10 Minuten weiter und an der Hinrichtungsstelle kommen die Insassen schon tot an und werden sofort in die Gruben geworfen. Nachmittags machte ich in der Hinrichtungszelle einige Aufnahmen mit Böhms Sonne.

7.4.42. Very early, Colonel Marschall called me; I was to immediately scout the North Camp for expansion possibilities. I left with Janusch at 8, and it turned out that the camp is of no use. The Colonel also came out later and agreed with me. On the return trip, we inspected the execution cell and the GPU prison cells, which are now occupied by the Security Police. In each cell 4 to 6 people used to sit. With us [handwritten: i. e. with the secret field police], the people are likewise executed by pistol shots to the back of the neck, or they are transported away in a gas van (Gasauto). It stops outside the city and redirects the exhaust gases in such a way that they enter the interior of the vehicle. Then the vehicle drives on for another 10 minutes, and by the time they reach the execution site, the occupants arrive already dead and are immediately thrown into the pits. In the afternoon, I took some photos in the execution cell using a "Böhm's Sun".

The archival source provided by Vershinin is BArch MSG 2/10902, Bl. 209.

The question of the authenticity of the diary (i.e. whether the text is contemporaneous to the events it describes or whether it's a memoir in form of a diary) was analyzed by Christian Hartmann in this article. As he points out, retroactively faking 450 double-sided, detail-filled sheets for an incomprehesible purpose is simply implausible (there are also other arguments). What cannot be entirely excluded, however, is that the diary could have been retyped after 1945. The forensic testing of the materials showed them to have been available throughout the 1940s.This means that in theory some passages could have been deleted or added during the retyping.

That said, the purpose of adding a passage like this after the war eludes me. It would be incriminating, if anything. It also fits with the gas vans having arrived in Smolensk just a couple of months prior to this entry.

Tales of Junk Demography: How Sanning Invented 100,000 European Jews in Morocco

In Chapter Seven dealing with post-war Jewish migration, Sanning tries to convince his readers that part of the Oriental Jews who came to Israel during the first two decades after its declaration of independence were, in fact, European Jews. Among them, allegedly 100,000 out of 252,642 Moroccan olims.

To support his assertion, he cited the results of 1936 French Moroccan census, which found 161,000 Jews, then implied a natural increase of 1 percent per a year and stated Moroccan Jewish population was 50,000 in 1970. This would allow the native Moroccan Jewish community to give Israel only 150,000 new souls, by 100,000 less than actually arrived. The self-appointed revisionist demographer concluded the only explanation is the mass resettlement of 100,000 European Jews in Moroccan territory during the war or shortly after (Walter Sanning, The Dissolution of Eastern European Jewry, p. 164).

Note: In the case of France, Sanning assumed totally 170,000 North African Jewish newcomers, 110,000 from Algeria and 60,000 from Tunisia (ibid., p. 169).

Sanning's calculation is, of course, wrong.

Tales of Junk Demography: An Introduction

 Over 17 years ago Jonathan Harisson finished his series The Crazy World of Walter Sanning criticizing The Dissolution of Eastern European Jewry, the 1980s "revisionist" attempt of study of Jewish demography.

Sanning is still taken seriously by many Holocaust deniers. Deanna Spingola heavily refered to The Dissolution of Eastern European Jewry in The Ruling Elite: Death, Destruction, and Domination published in 2014. Don't forget about Ryan Faulk. Or X Nazi star Karl Radl.

Willi Lenz: The “Doctor” of the Kulmhof (Chełmno) Extermination Camp

When Soviet troops reached the area around Chełmno nad Nerem in January 1945, the Nazi extermination camp Kulmhof had already been largely dismantled.¹ Nevertheless, contemporary documents and witness testimony preserve evidence about the men who operated the camp.

One name appears repeatedly in these sources: Willi Lenz, a Polizeimeister of the Schutzpolizei. At Kulmhof, he supervised Jewish forced laborers in the so-called forest camp, personally carried out shootings, and oversaw the disposal of the corpses.

Studies of Kulmhof describe Lenz as an exceptionally brutal person (see endnote 1), but provide little information about his background and career. Using contemporary civil records, police files, NSDAP membership documentation and postwar testimony, this article establishes his identity and reconstructs a life-spanning, though still fragmentary, biography of Willi Lenz. 

What Vladimir Davydov really said about the height of the Babyn Yar pyres.

It has long been a staple argument of the deniers against one Babyn Yar witness Vladimir Davydov (one, but not the only, contrary to the incompetent nincompoops Carlo Mattogno and Jürgen Graf's claim) that he claimed the height of 10-12 m for the Babyn Yar pyres in 1943.

Mattogno and Graf wrote:

On November 9, 1944, Major Lavrenko, member of the Commission for the Investigation of German Crimes in Kiev, questioned the Jewish witness Vladimir K. Davidov. The latter stated that on August 18, 1943, he, along with 99 other prisoners, for the most part also Jewish, had been selected from the Siretzki concentration camp 5 km from Kiev. The 100 prisoners were taken to Babi Yar and there were forced to dig up the bodies of the Jews shot in 1941. According to him, 70,000 bodies had been in the mass graves of Babi Yar. The prisoners had exhumed these and burned them on 'ovens' afterwards, which consisted of granite blocks - procured from the Jewish cemetery of Kiev - with train rails laid upon them. On these a layer of wood was piled and on top of this the bodies, so that an enormous stack of bodies 10 to 12 m high resulted! In the beginning there was merely a single 'oven,' but then 75 of them (literally seventy-five) were built.

No other witness claimed something like this and Davydov himself stated in 1967 that the height was actually 4 m.

But what of his original claim? Well, now we have the original BY investigation files from 1943 and 1944.

Otto Moll - Dear Gardener Next Door Or Psychopathological Mass Murderer?

Otto Moll, born in 1915 in Mecklenburg, trained as a gardener before joining the SS-Wachverband V "Brandenburg" in 1935. His early life was marked by personal hardship: a serious car accident in 1937 left him with a skull fracture and blindness in one eye, and in 1940 his first wife and unborn child died from blood poisoning. By April 1938, he was working in the SS garden at the Sachsenhausen concentration camp, and he soon became part of the expanding concentration camp system.

According to his own statement to US investigators from November 3, 1945, "from 1941 until January 1945, I likewise managed a gardening unit of the Economic and Administrative Main Office in the Auschwitz concentration camp". 

Afterwards, Moll was stationed at the Kaufering II subcamp of the Dachau concentration camp. Moll stated that "no prisoner in my camp died from illness or malnutrition, and none were hanged or shot. There was not a single death in my camp ... no mistreatment of any prisoners by any guards occurred. No prisoner was beaten, kicked, or otherwise abused by the guards".

At the CODOH Holocaust denial discussion forum, the poster Stubble writes that "Going over what there is, I can't rule out that he indeed just ran the garden (farm) detail and was hated for it, and thus framed up for something different". 

The record tells a very different story. 

Twenty years of HC blog

Happy birthday to us: exactly twenty years ago, the Holocaust Controversies blog was kicked off with the first of over 1,500 posts. It's a strange anniversary given how much time has elapsed and how different the world now is. 

Back then, the HC team met online at the original Real Open Debate on the Holocaust forum, an old-fashioned bulletin board, before any of today's social media platforms existed. While Holocaust 'revisionism' had been dealt a huge blow in 2000 with the defeat of David Irving's libel suit against Deborah Lipstadt in London, it seemed to be surging online, largely ignored by the mainstream media. Many of the HC team had been arguing with Holocaust deniers online for years. I myself stumbled across it when googling for materials on Auschwitz, and could scarcely avoid what seemed like a barrage of revisionist propaganda materials. Thus the decision to found the blog.

Twenty years on, the landscape is entirely different. Holocaust denial in 2026 presents an even more paradoxical picture: it has surged once again on various social media platforms, but in a largely headless form, part of a wider upsurge in antisemitism online in the past two to three years. And with that surge, HC's views have as well, passing six million since May 2010 in July 2025 and seven million in February 2026.

First Published Photographs of Nazi Homicidal Gas Van with Engine Exhaust

Cameron A. Munro has recently published "Engineered for Mass Murder – The Nazi Gas Vans: 1939–1945", a book in which he presents 15 photographs depicting a homicidal gas van built on a petrol-powered Diamond T chassis. 

These photographs were taken in April 1942 by SS-Rottenführer August Vielkind of the Waffen-SS reserve, who was part of the advance detachment of Sonderkommando 7a of Einsatzgruppe B, marching from Klintsy via Gomel to Sychyovka. The images were used by prosecutors in Dortmund during investigations into members of Sonderkommando 7a. However, as Munro notes, it seems they "did not forward the photographs to West-German investigators of other units" and "the photographs then lay forgotten in the files of the Landesarchiv Nordrhein-Westfalen in Münster for many years". 

It’s remarkable that such historically significant material can still be discovered after so many years. And fittingly - characteristic of authentic historical research - the deeper one digs, the more corroborating rather than contradicting evidence tends to emerge. 

I highly recommend it to anyone interested in the history and mechanics of the Nazi homicidal gas vans.

 

Saurer Company or Why even Rudolf has shown the Diesel Issue is irrelevant on Gas Vans ("Rebuttal of "Holocaust Encyclopedia")

For decades, Holocaust deniers have claimed that the Saurer gas vans had to have diesel engines, and since diesel exhaust has lower carbon monoxide, they conclude the vans couldn’t have been used for murder. The argument is irrelevant as the RSHA turned chassis with gasoline engines into gas vans. A detailed refutation of the "diesel issue" argument was published ten years ago and has never been answered in substance to my knowledge (see Rebuttal of Alvarez on Gas Vans: Why the Diesel Issue is Still Irrelevant). Denier Alvarez’s new edition (2023) of his book "The Gas Vans" continues to repeat it, without a single source, counter-argument, or whisper of a rebuttal to the refutations that already exist. 

Germar Rudolf’s entry "Saurer Company" in CODOH's Holocaust Encyclopedia tries a fresh variation:

He notes that the RSHA motor pool acquired a number of Saurer 5-ton chassis in 1942  and the company Gaubschat in Berlin built a cargo box on each chassis - "for an unspecified purpose".  The historical consensus (or as Rudolf  like to call it "orthodoxy") holds that these were mobile gas chambers. Rudolf argues that because gasoline-engined trucks were supposedly "much easier" to obtain from other manufacturers, the RSHA’s Saurers “must have had diesel engines".

Here’s where the things get interesting. 

Rudolf concedes for the first time what deniers once swore was impossible and what we have pointed out at this blog: that Saurer did, in fact, produce gasoline-engine trucks during the war - in the French factory in Suresnes near Paris
