The Morgues of the Crematoria at Birkenau in the Light of Documents
By Carlo Mattogno ∙ August 1, 2004
In the historical expert opinion drawn up for Deborah Lipstadt in the libel trial launched against her by David Irving (January 11 to April 11, 2000), Robert Jan van Pelt, when he was unable to find any proof of the reality of the extermination of Jews in gas chambers at Auschwitz, amassed all the available "traces," most of them already gathered by J.-C. Pressac, raised them falsely to the higher level of "proof," and later invented a "convergence of evidence" essentially based upon a systematic disfiguration of the documents. Also, all documents that did not lend themselves to such an operation of disguise were simply ignored by him.

Wartime Germany’s Anti-Gas Air Raid Shelters
A Refutation of Pressac’s ‘Criminal Traces’
By Samuel Crowell ∙ December 15, 1999
As Holocaust historians concede, hard evidence for mass killings in Second World War gas chambers has proven to be elusive. After an extensive search, especially of wartime German wartime records held in Polish archives, French author Jean-Claude Pressac acknowledged in his detailed 1989 study, Auschwitz: Technique and Operation of the Gas Chambers, that he was unable to find any direct proof of wartime gas chamber killings at Auschwitz (including the its nearby satellite camp of Birkenau). Instead, he offered 39 documentary “criminal traces” of such gassings – what he called “indirect proofs.”
These “traces” are wartime documents, mostly from the Auschwitz central construction office, that contain passing references to “gas tight doors,” “gas detectors,” and such. In the view of Pressac, and other defenders of the standard Holocaust story, these are implicit references to equipment or devices that were part of homicidal gassing operations.
In the following essay, American researcher Samuel Crowell presents detailed evidence of benign explanations for these “criminal traces.”[1] His basic argument is that the documents cited by Pressac as “traces” of homicidal “gas chambers” are references to air raid shelters, or to their fittings or equipment. Specifically, he contends, the Birkenau crematory morgue rooms – the supposed “gas chambers” where, it is alleged, hundreds of thousands of Jews were killed with “Zyklon” pesticide – were modified to also serve as air raid shelters with features to protect against possible Allied attacks with poison gas.
Crowell extensively cites contemporary German specialized literature on wartime air raid shelters and measures against possible air attacks with poison gas to argue that such shelters, and their equipment, were widely used throughout wartime Germany, including in the concentration camps. He contends that seemingly damning documentary references to “gas tight doors” and so forth actually refer to normal civil air defense equipment. He therefore concludes that there is no documentary proof – direct or indirect – of homicidal gas chambers at Auschwitz-Birkenau.

Criminal Traces 18 and 20, and 19 and 21: ‘Gas’ Windows and ‘Gas’ Chamber
“Traces” 18 and 20 mention putting “gass [sic] tight window” in place (Gassdichtenfenster versetzen), while “traces” 19 and 21 mention “concrete in gas chamber” (betonieren im Gasskammer). Pressac regards these “traces” – which are from February and March 1943 and relate to Birkenau Kremas IV and V – as very important evidence of homicidal gassings at Birkenau.
As already pointed out, gas tight windows were a common feature of German anti-gas shelters.[85] In addition, and as already noted, these objects are identical to the “shutters” (Blenden).
These four “traces” are dealt with here together because in each the word “gas” (Gas in German) is misspelled. In these four “traces” it is rendered as “Gass.” I do not agree with Pressac’s view that these are simple misspellings. Instead, I’m inclined to think that they are abbreviations: “tight windows for the [anti-gas shelter]” (Gass[chutzraum]dichtenfenster) and “[anti-]gas shelter” (Gass[chutz]kammer).[86]
In any case, a benign interpretation is possible. Therefore, these are not criminal traces.

Well, it isn't clear that there is much to be gained from the brick remnants of Crema IV and V. An attempt was made to measure cyanide traces there, and they came back with minute cyanide levels (similar to control samples, so low they may be equivalent to zero), but it's not even certain to what extent these brick remains are original.Joe Splink wrote: ↑Sat Jan 31, 2026 3:34 am Wow. Hard to follow all that (Pressac, Mattogno) ... without some serious effort. I'm wondering why there is no mention (that I saw) of what remains of these rooms.
Yes, I had some difficulty too. Mattogno tends to put all his documents in the back of his books which makes them harder to read but easier for him to continue referencing throughout the text. I have to screenshot his diagrams to look back at as I read.Joe Splink wrote: ↑Sat Jan 31, 2026 3:34 am Also, I couldn't form a picture of the relative location, doors, sizes, and possible purposes of the rooms discussed 8, 9 , 10, 11 (?).
True, although in online debates I have never seen anyone employ this particular document. I'm not yet volunteering to write this rebuttal but one of us ought to.Joe Splink wrote: ↑Sat Jan 31, 2026 3:34 am Perhaps since the Auschwitz museum cites this reference as one of two documents that constitute the documentation of the best documented genocide in history, it might be a good idea to formulate a concise, comprehensive, and understandable rebuttal.
That's correct.Joe Splink wrote: ↑Sat Jan 31, 2026 6:50 pm And I'm having a problem reconciling them. It must be the case that the roof on the rear 1/5 of the building is lower than the front roof?
Yes. All three rooms have multiple windows and doors. I'm not sure the exact origin of the story, but those windows became interpreted as Zyklon insertion windows. The absurdity of this theory leads to this oft-quoted passage from Pressac (p.386):Joe Splink wrote: ↑Sat Jan 31, 2026 6:50 pm In any case, from the blueprint, it appears that the 'gas chambers' have 3 windows and a door, which is absurd.
The revisionist theory would be that these windows were deliberately made small and high-up as a matter of privacy. Anyone undressing, showering, and being inspected by the doctor would enjoy the benefit of that privacy.Although the operating sequence looks simple enough, it had become irrational and ridiculous. It was irrational to have the victims going from the central room to the gas chambers then being brought back, thus destroying the linear logic of the initial design. It was ridiculous to have an SS man in a gasmask balancing on his short ladder with a 1 kg can of Zyklon B in his left hand while he opened and then closed the 30 by 40 cm shutter through which he introduced the pellets with his right hand. This performance was to be repeated six times. [...]

What is the explanation?
Thanks - I wondered a bit about Pressac's claim, and your explication clears it up. Pressac was capable of subtle reasoning!Wetzelrad wrote: ↑Sat Jan 31, 2026 7:47 pm I didn't fully develop this argument above, but if Pressac was correct that the foreman "sensibly deduced" the room is a gas chamber, then this supposed criminal trace is no more incriminating than whatever he deduced it from, which Pressac thought was just the gas-tight windows. Pressac has a tendency to undermine his own suppositions like this, which is probably why the Auschwitz Museum leaves his name out.
