https://www.vho.org/GB/Journals/JHR/10/3/LeuchterFaurisson261-322.htmlDocument PS-1515, 24 May 1945 (original language: German). The so-called "Deposition of the Camp Commander of Mauthausen Concentration Camp, SS Colonel (Standartenführer) Franz Ziereis." In its original form, this ten page document, typewritten in German, does not bear any signature. It says: "Franz Ziereis, lying on a straw pallet, wounded in the stomach and the left arm by two shots made the following declaration to questions put to him by two persons of Intelligence." Franz Ziereis was interrogated for six to eight hours, then he died. That torture session took place in the presence of the American General Seibel, Commandant of the 11th Armored Division (still living in 1989, in Defiance, Ohio). One of the two interrogators was Hans Marsalek, a former prisoner, who now lives in Vienna, Austria, a high official of the police and the author of numerous works on Mauthausen:
By order of the SS-Haupsturmführer Dr. Krebsbach, a chamber camouflaged as a bath-room was built in Mauthausen Concentration Camp. The prisoners were gassed in that camouflaged bath-room [ . . . ]. Actually the gas chamber was constructed in Mauthausen by order of SS-Obergruppenführer Glucks, who advocated the viewpoint that it was more humane to gas prisoners than to shoot them.
This "deposition" is sometimes interrupted by remarks on the part of the interrogators, e.g., about the "insolent arrogance" of Ziereis. It ends with the following words: "Furthermore, Ziereis declares that, according to his estimation some 16,000,000 (??) people have been murdered in the entire territory of Warsaw, Kowno, Riga and Libau."
For the comments that Ziereis supposedly had on Hartheim Castle, see below, "Hartheim Castle."

Faurisson furthermore writes that Simon Wiesenthal partly and incorrectly reproduces the document in his book KZ-Mauthausen
It should be in IMT volume XXVII, however, document PS-1514 (pp. 261–269) is immediately followed by PS-1517 (pp. 270–273), with the document number skipping two digits. I haven’t been able to locate it or find other, independent sources which quote from this document. Is it in the French edition of the Nuremberg proceedings?Simon Wiesenthal, KZ-Mauthausen, Linz & Vienna, Ibis Verlag, 1946 (original language: German). The author reproduces what he calls the "confession" of the commandant of Mauthausen, pp. 7-13. In reality, he reproduces document PS-1515, but only in part and with strange changes; for example, the number of 16,000,000 persons put to death in the whole of the territory of Warsaw, Kowno, Riga, and Libau is reduced by Wiesenthal to "10,000,000" (p. 13).
