Topic - Sobibor

Unlike many other Nazi concentration camps, Sobibor existed for the sole purpose of exterminating Jews. Most new arrivals were immediately sent to the gas chambers, with rare exceptions being made for those who were forced to serve as slave labourers who assisted in the operation of the camp. Some 200,000 to 250,000 making it the fourth deadliest extermination camp after Belzec, Treblinka, and Auschwitz. - Source: Wikipedia
