History

At first, the Germans held Polish political prisoners in the camp. From the spring of 1942 Auschwitz became the largest site for the murder of Jews brought here under the Nazi plan for their extermination. More than 1,100,000 men, women, and children lost their lives here.

E não eram 4.000.000???

O que fizeram com o resto?
