deported to perform forced labour in the Reich. Euphemistically referred to as a "transit camp for refugees" by its administrators, it was established on a portion of the abandoned Teslić factory, which was surrounded by barbed wire. The German authorities sent some of the able-bodied prisoners from Sisak I to the Sajmište concentration camp, directly across the border from German-occupied Belgrade. Other prisoners met various fates in different German camps, such as Augsburg, Auschwitz, Dachau, Mauthausen, and Salzgitter. Some were sent to German-run camps in occupied Norway. Sisak I was expanded in 1942 with the construction of seven additional barracks. By the following year, it had a total capacity of 5,000. The German authorities ceded control over Sisak I to the NDH and the Ustaše in April 1944. The camp was eventually shut down in January 1945, with its remaining inmates dispatched to Jasenovac, the largest of the Ustaše camps. Sisak II Establishment The second sub-camp, Sisak II, was reserved for those who were deemed unfit for forced labour. Its operators euphemistically referred to it as a "reception center for children and refugees" or the "shelter for children refugees". According to the historian Joseph Robert White, the first 1,200 children arrived from the Mlaka sub-camp on 29 July 1942, with subsequent transfers from Jasenovac V (Stara Gradiška) and Jastrebarsko taking place in August. According to the historians Paul R. Bartrop and Eve E. Grimm, Sisak II was officially established on 3 August 1942, following the Kozara Offensive (). The first group of 906 children arrived at Sisak II on 3 August, according to Bartrop and Grimm, with an additional 650 children arriving the following day, and a third group of 1,272 on 6 August. The Ustaše dispersed the children of Sisak II among the Sisters of Saint Vincent Convent, a site that formerly belonged to the Yugoslav Sokol recreational society, the Reis Saltworks and a primary school in the neighbourhood of Novi Sisak. Children under the age of three were detained in the convent, whereas those between the ages of four and five were confined to the saltworks. Sisak II was administered by the physician Antun Najžer. The commander of the camp guards was an individual with the surname Faget. Female Ustaše guards also took part in overseeing the camp. The German Sicherheitsdienst (SD) also sent a representative to Sisak, and German field gendarmes provided security around the two sub-camps
