Forgotten Horrors: The Nazi sub-camp system

  Sosnowitz II was established at a rolling mill operated by Oberschlesiesche Maschinen u. Waggonfabrik in Sosnowiec. Initially there were 200 prisoners, the vast majority of whom were Jews, who arrived in May 1944 and held at a former camp for foreign conscript workers. The numbers of prisoners increased to 600 later in the year and to 900 by the end of the year. They were held in three wooden barracks surrounded by an electrified barbed wire fence and overlooked by seven guard towers. Other buildings at the site consisted of a kitchen, washroom, store and latrine. The camp was commanded by SS-Hauptscharführer Albin Vaupel. Prisoners were put to work manufacturing weapon parts, such as gun barrels and ammunition. The prisoners were evacuated in January 1945 when they were taken on foot to Opava in Bohemia and then transported by train to Mauthausen.

  Sosnowitz I was established in late August 1943 in order to remodel a building at Targowa Street 12 which had previously served as the office for the Central Jewish Council of Elders. Around 100 prisoners, most of whom were Polish, were held in a room on the ground floor of the building where they had to sleep on straw laid directly on the floor. The windows were covered by metal grilles and 15 SS men were deployed to guard them. The subcamp was commanded initially by SS-Rottenführer Lehmann followed by SS-Unterscharführer Horst Czerwiński. After completion of the work, the prisoners were returned to Auschwitz in two groups, the first returning in December 1943 and the second in mid-February 1944.

  Bobrek was a subcamp of Monowitz concentration camp located in or near Bobrek, Lesser Poland Voivodeship, Poland, and was part of the Auschwitz concentration camp complex. It was built by Siemens-Schuckert and held approximately 250-300 prisoners including 50 women who were used as slave labor to produce electrical parts for aircraft and U-boat submarines. The commandant of the camp was SS-Scharführer Hermann Buch. Bobrek subcamp was evacuated along with the other camps in the Auschwitz complex on January 18, 1945. The prisoners were sent on a death march to a concentration camp in Gleiwitz, Poland. Many were then transported by rail to Buchenwald concentration camp. While in Buchenwald, the former Bobrek workers were sought out by Siemens-Schuckert executives, who had them transported to the Siemens-Schuckert factory in Siemensstadt, a suburb of Berlin. A sub-camp located 3 km north of Oświęcim in fertilizer-factory buildings in Bobrek that belonged before the war to Anna Kuppe

Blechhammer was the second largest subcamp of Auschwitz and was located, along with several other camps, in the Blechhammer industrial area. The camp was established on 1st April 1944, utilising an existing forced labour camp that was transferred to the Monowitz concentration camp administration. The camp initially held around 3,000 male and 200 female prisoners in 25 barracks covering 10 acres. It was surrounded by a 4 metre (13 ft) high concrete wall. Around 4,500 prisoners passed through the camp during the course of its existence.  The work carried out by the prisoners consisted mostly of construction, excavation and hauling wagons. Some prisoners were forced to remove unexploded bombs following the air raid at the nearby Hydrierwerke plant. The prisoners were occasionally subjected to selections by the SS guards, in which those considered unfit for work were removed to Birkenau where many of them were executed. Another 250 prisoners were killed at Blechhammer itself and their bodi

Laurahutte was established inside the steelworks in Siemianowice Śląskie, owned by the massive company Rheinmetall Borsig AG, based in Dusseldorf. It opened in early 1944 with an initial transport of 200 prisoners to the site, the majority of whom were French and Dutch Jews. However, more prisoners arrived at the site over the course of subsequent months, rising to 550 by summer 1944 and 937 by the time of the sub-camp's evacuation.  The prisoners were held inside the factory grounds, sleeping on three-tier bunks with access to a kitchen barracks, an infirmary and a storehouse. The sub-camp was surrounded by a three-metre high wall with barbed wire along the top and guard towers at the corners. It was commanded by SS-Oberscharfuhrer Walter Quakernack. The guards consisted of a small number of SS men with the majority being coastal artillery soldiers commanded by
