In addition to Jews from Częstochowa, more Jews were brought in by rail from nearby towns and villages of the Generalgouvernement part of occupied south-western Second Polish Republic, including from Krzepice, Olsztyn, Mstów, Janów, and Przyrów, on top of expellees from Polish lands annexed into the Reich at the beginning of war, mostly from Płock and Łódź.
The ghetto inmates were forced to work as slave labour in the armaments industry, a majority of them in the expanded Polish foundry "Metalurgia" located on Krotka Street (which had been taken over by the German manufacturer HASAG, and renamed Hassag-Eisenhütte AG) as well as in other local factories or workshops.
The action was carried out by German units together with their Ukrainian and Latvian auxiliaries (Hiwis), known as Trawniki men, under the command of captain of the Schupo police, Paul Degenhardt.
Every day, the Jews were being assembled on Daszyński square for "resettlement" and then transported by the Holocaust freight trains – men, women and children – to Treblinka extermination camp: around 40,000 victims in total.
[7] Jan Brust from Żegota was shot in the first half of 1944 for delivering food to the Jewish inmates of the slave labour facility.
[8] Other members of the Brust family in Częstochowa helped to aid and shelter Jews, and after the war received the Righteous award.
