Germany – A Third Reich gambit both to transport victims to Concentration and Death Camps, and to simultaneously to inflict severe abomination, debasement, trauma and humiliation on (millions of) decent people (overwhelmingly Jewish) over (generally) 1–9 day sustained periods of deprivation of essentially all the basic human needs (except some limited air). 50–100+ persons were ordered into a freight car. No food or water was provided and one toilet bucket per freight car.
Aside from the de facto psychological death sentence unfolding fairly quickly, many died physically in the freight cars from starvation, asphyxiation, debasement or the temperature (whether freezing cold or stifling hot, or both during a 24 hour period). In other words, rolling torture chambers.
Severely degrading their targeted victims (most often family–units) psychologically and physically, in preparation for the salient Nazi “contribution to history”: the Nazi gas chamber.
