Prisoner work details at the main campWork at the camp was marked by violence and harassment. During the early years of the camp, most prisoners were forced into construction and excavation work, the canalisation of the Dove Elbe or the transportation of goods and materials. They had to work from morning to evening in the rain, the heat and the freezing cold, spurred on by the blows of the guards. Some prisoners also worked in the camp itself. From 1942, more and more prisoners had to work in the camp’s production facilities, particularly in the brickworks, the Jastram, Messap and Walther ("Metallwerke Neuengamme") armaments factories, and the SS-owned DAW ("Deutsche Ausrüstungswerke") armaments works.
