What is "bromberg-ost"

Bromberg-Ost was the female subcamp of the German Nazi concentration camp KL Stutthof between 1944-1945, set up in the city of Bydgoszcz during the later stages of World War II. The mostly Jewish women prisoners dispatched from the main camp in Sztutowo worked as slave-labour for the German railways; loading cargo, clearing and repairing tracks, and digging ditches. The commandant of the camp was SS-Scharführer Anton Kniffke. No warm clothing was provided before mid-December. Women who managed to survive were taken on a death march to Sachsenhausen-Oranienburg.
