he Neuengamme concentration camp was established as a subcamp of Sachsenhausen at an abandoned brickworks in Hamburg, Germany. Camp prisoners were used as forced laborers in several industries including a renovation of the brickworks. Until 1944, few Jews were imprisoned in Neuengamme. Before then, most prisoners were political criminals from the German-occupied countries. Inmates at Neuengamme were subject to horrible conditions, forced labor, and medical experiments. Nearly half of all the prisoners who entered the Neuengamme camp system died. By the time British forces liberated the camp, nearly all the prisoners had been evacuated or killed during death marches.
