Warszawa Zachodnia station in the context of "Dzielnica"

Dulag 121 camp in Pruszków (Durchgangslager [pl] 121 Pruszków) was a Nazi transit camp where civilian population from Warsaw and surrounding areas, expelled from their homes during and after the Warsaw Uprising, was gathered.

The camp was established on 6 August 1944, on the premises of the former Railway Rolling Stock Repair Works in Pruszków [pl]. It operated until mid-December 1944, and in a residual form, until 16 January 1945. During this period, between 390,000 and 410,000 people passed through Dulag 121, among whom tens of thousands were deported to forced labor in the depths of the Reich or sent to concentration camps after a short stay in the camp. Due to diseases, exhaustion, or at the hands of guards, hundreds to several thousand prisoners of Dulag 121 perished. However, over 30,000 people managed to leave the camp thanks to the assistance of the Polish personnel employed there.
