1942-06-02 / SS-Officer Just’s Memo on Gas Vans: “97,000 have been processed using 3 deployed vehicles”
Memo dated June 5, 1942, authored by SS-Hauptsturmführer Willy Just of RSHA office II D 3 a (Motor Vehicle Department of the Security Police) on technical modifications to the gas vans used in mass killing operations. Just reports that “since December 1941 97,000 have been processed using 3 deployed vehicles, without any defects occurring in the vehicles” and “the known explosion in Kulmhof (Chełmno) is to be considered an isolated case due to an operating error”. He proposes the following “technical modifications to the special vehicles currently in operation and those under production”, among other things ventilation slots on the upper rear wall to allow “a rapid inflow of CO without causing overpressure”. The proposal was reviewed by Walther Rauff, head of the Motor Vehicle Department, on June 10, 1942. He approved the implementation of the modifications on a prototype vehicle.
