“UNTERDRUCKVENTIL”
While I was visiting the revisionist activist, researcher and publisher Vincent Reynouard in France, I used the opportunity to visit Utah and Omaha Beach, especially the German “Batterie de Crisbecq/Marcouf.” Even 5 days after the landing of the Americans in 1944, the battery was still operational, causing the Americans a lot of problems.
One can read more from the German viewpoint in the book Ils arrivent! Le débarquement des alliés en Normandie by Paul Carrell, who was a French Waffen-SS volunteer (if I’m not wrong). The book is also available in German, published by Ullstein Verlag, Germany.

Most interesting to me was the Kommandobunker. The present e-mail is accompanied, in attachment [not included here], by photographs of the airtight entrance to the bunker, taken from both the outside and inside.
Another picture shows an opening, equipped with airtight doors, bearing the written notice: “Bei Gas Türe zu” (“In Case of Gas Attack Close Doors”). To the right, there is a kind of telephone-device with, underneath it, a device referred to in a painted notice as an “Undendruckventil” [apparently the bunkers have been repainted for the tourists, since the correct German term for this would be Unterdruckventil, usually translated as “vacuum valve” or “underpressure valve”].
When I returned home, I researched the meaning of the word Unterdruckventil and the function of the valve in these bunkers, but I got no answer from engineering experts. I asked the Museum Administration, and am still waiting for an answer three months later.
In my opinion, this device was intended for use, in the event of gas attack, to create an “over-pressure” inside the Kommandobunker, thus preventing toxic gases from entering the bunker. [American gas chambers are designed to create a partial vacuum inside the chamber to prevent the escape of any deadly gas to the exterior, endangering the witnesses to an execution. Obviously, in an air-raid shelter, the same principle would work in reverse: the valve would be designed to prevent the leak of toxic gases inwards, rather than outwards. Theoretically, it should be possible to tell by the design of the valve or valves whether or not a structure is an execution gas chamber or, in fact, an air raid shelter.]
The problem of this “underpressure valve” or “vacuum valve” has major consequences where revisionism is concerned, because there is no indication of any such device in the [so-called] “homicidal gas chamber” at Auschwitz I (Main Camp). Nor do the very detailed inventory-registers of the premises at Birkenau contain any mention of any such valve at Birkenau. There is no mention of such valves (prices, technical descriptions, etc.) in the correspondence between the various manufacturers involved and the Bauleitung [or Construction Administration].
Conclusion: after “No Holes, No Holocaust” (by Robert Faurisson) we may perhaps now add: “No Unterdruckventil, No Gas Chambers.”
Can anyone among our SR readers provide us with more information about this “Unterdruckventil” issue?
