“…Indeed, in its dimensions and total configuration, nothing like it had ever happened before" (Hilberg, 2003, p. 5). It was partly due to the scale of the planned genocide that the camp system was deemed necessary: although face‐to‐face murder by mobile killing units ( Einsatzgruppen ) killed over 1.4 million people (Hilberg, 2003), the death‐camp system was considered a "final solution" to both the inefficiencies of decentralised killing and the emotional toll experienced by those undertaking close‐quarter mass murder (Arad, 1999). The extermination camps (Auschwitz‐Birkenau, Belzec, Chelmno, Majdanek, Sobibor, and Treblinka) murdered approximately 3 million Jews and, as Wachsmann writes, the most advanced camp, Auschwitz‐Birkenau, enabled the Nazi regime to "systematically kill Jews from all across the continent, deported to their deaths from Hungary, Poland, France, the Netherlands, Greece, Czechoslovakia, Belgium, Germany, Austria, Croatia, Italy, and Norway" (Wachsmann, 2015, p. 291).…”
