The next group of inmates to be exterminated at Gusen by heaviest work had been Soviet Prisoners of War. This group of inmates was also the first to be gassed in 1942. Several Spanish republican prisoners were sent also sent to Gusen to be exterminated. More than 2,000 of them had to work in the stone-quarries and very few of them survived One of the "specialties" of this camp "Todebadeaktionen" death bath action. The inmates were selected to the "bath" during the appeal: inmates unable to work or ill. They were then sent to the "bath room" and had to stay naked under the showers. Then icy water under high pressure fell from the showers. The temperature of the bodies was falling down and caused a long and painful agony. The agony of this death could last as long as a half-hour. Gusen was liberated on May 5, 1945, by the rec.squadron of sergeant Albert J.Kosiek. More than 37,000 inmates died at Gusen. This is more than 1/3 of all the victims of all the other camps located in Austria.
