The efficacy of the drugs were tested in normal manner but morphed into atrocity stories. The fumigation chamber similar to the one at Stutthof depicted in the photo below also morphed into a gaskammer for murder. The gaskammer was small and could only apparently hold about 100 women at a time. The alleged gassing allegedly occurred also in Satellite camps, as the red Army approached. There were apparently no Kula columns in this gaskammer, just Zb thrown in through the top of the roof; a single 500g can.
Now we have der jüdische Lügner Сергеи Романовы from "klowns" trying to reinforce the gassing claim with the following load of cattle excrement one could only expect from Jude, and a Russki one at that. Еврей-лжец Сергей Романовы не умеет читать или писать по-русски, но это не имеет значения. You can read its crap here where according to the judensau, Mittwerda has become a euphamism for gaskammer.
The truth is that as the war came to its conclusion there was intense overcrowding at this camp, where a typhus epidemic took hold. One can blame the allies for this.
“Die Gaskammer im Konzentrationslager Ravensbrück Anfang" has Olga Wormser-Migot, a woman of jüdische descent denied the existence of this gaskammer. When British and American troops reached these camps, they considered the horrifying scenes they saw in the camps as a confirmation of the intensive propaganda they had been subjected to over the years. They believed that the National Socialists had exterminated entire groups of people, Jews in particular, and ascribed the extreme mortality to an intentional policy of killing the inmates, which, in their opinion, had also been accomplished by means of gas chambers.
The existence of gas chambers immediately became a dogma which the SS defendants could not question without risking to get entangled in a hopeless situation.
