All three Reinhard camps were in operation simultaneously for only four out of the six months from July to December 1942, yet in that half-year the three sites killed more than one million Jews, which is more Jews and nearly as many people all told as Auschwitz-Birkenau wiped out in four years. Altogether, these three places devoured between 1.5 and 1.8 million human beings. Including Chelmno, the four CO camps killed up to 2 million people.
