Witnesses have claimed all kinds of methods allegedly used in certain facilities to mass murder people at German wartime camps. Nowadays, the orthodoxy only recognizes claims as valid which posit the use of toxic gases, hence homicidal gas chambers (see that entry for details). However, during the war and in the immediate postwar years, when memories were still fresh, witnesses also claimed other murder methods that had nothing to do with toxic gases at all, such as:
- Vacuum, which can be found in accounts on Belzec and Treblinka, and rarer also for Auschwitz, but only as a first stage to gassing. See also the following entries: Rachel Auerbach, Hejnoch Brener, Vasily Grossman, Abe Kon, Aleksander Kudlik, Mordecai Lichtenstein, Henryk Poswolski, Chil Rajchman, Samuel Rajzman, Kazmierz Skarżyński, Oskar Strawczyński.
- High-voltage electricity, which was frequently claimed for the Belzec Camp, but also on rarer occasions for Auschwitz, Treblinka and Sobibór. See also the following entries: Srul Fajgielbaum, Boris Polevoy, Jakub Rabinowicz, Abraham Silberschein, Stefan Szende.
- Steam, a claim quite common for the Treblinka Camp. See also the following entries: Rachel Auerbach, Jakub Rabinowicz, Abraham Silberschein, Vasily Grossman, Eugenia Szajn-Lewin.
- A “dark substance,” which was claimed for the Sobibór Camp by Alexander Pechersk.
It was all fraudulent, though. Embarrassed by these indicators of witness mendacity, the orthodoxy today sweeps these propaganda falsehoods under the carpet.
