Sisak I The town of
Sisak, near the confluence of the
Sava and
Kupa rivers, is located more than southeast of Zagreb. During the war, Sisak hosted two sub-camps, which were initially jointly administered by the NDH authorities and the German Commissioner in Croatia (). The first sub-camp, Sisak I, served as a transit camp for thousands of captured Serbs,
Bosniaks, and Roma who were to be deported to perform forced labour in the Reich. Euphemistically referred to as a "transit camp for refugees" by its administrators, it was established on part of an abandoned 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 , 1942 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 () against the Partisans in northwestern Bosnia. 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
Sisak Novi. 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 Ustaša guards also took part in overseeing the camp. The intelligence agency of the
Nazi Party and the
Schutzstaffel (SS), the (SD), also sent a representative to Sisak, and German field gendarmes provided security around the two sub-camps and the adjacent railway.
Camp conditions and rescue efforts Despite the efforts of humanitarians such as
Diana Budisavljević and others, up to 40 children died at Sisak II on some days. Food parcels sent by the
Red Cross never reached the children. By late September 1942, the camp held 4,720 children. Poor sanitary conditions and lack of care resulted in a very high mortality rate among the children. Children were made to sleep on the floor, and malnutrition and dysentery were rife. Of the 162 children admitted to the City Hospital for Infectious Diseases in Zagreb over the course of 1942, 145 died. Many had previously been interned at Sisak. In August and September 1942, it is estimated that Sisak II contained 3,971 child prisoners. Some of the camp's children were killed by being given
lethal injections, personally administered by Najžer. Others were killed by being fed
gruel laced with
caustic soda, according to survivors. One former prisoner recalled how her sister "came down with a high fever and vomiting" and died after drinking poisoned milk. NDH official Ante Dumbović authored a report in which he noted that the nuns tasked with looking after the children did not even know their names. This prompted Dumbović to place metal plates around the children's necks with their names inscribed. The poor living conditions at Sisak II shocked many observers, including Dumbović, as well as representatives of the
Croatian Red Cross. Dumbović documented the conditions at Sisak with his camera, taking 755 photographs of the emaciated children, some dead or dying, and others lying naked on the floor. At the time of his inspection, Dumbović found that 956 children had died in the camp, of whom only 201 could be identified by name. Three women affiliated with the Croatian Red Cross—Jana Koch, Vera Luketić, and Luketić's mother, Dragica Habazin—visited Sisak II in September 1942 and interviewed Najžer. He denied that any of the inmates were suffering, apart from some internees at the primary school who were described as being "sick". Many children were rescued by volunteers affiliated with the communist
resistance, who found them jobs as domestic servants or farm workers. Rescuers often worked under code names in secret cells, coordinating their activities from farmhouses as well as the homes of local Croats. Approximately 2,200 children were resettled in Zagreb, while families from Sisak and surrounding villages sheltered 1,630 children rescued from the camp. In some cases, the children were released to their parents or close relatives, while many others were placed in
foster care. Either because of the NDH policy of forced conversion or out of expedience, many were baptized into the
Roman Catholic faith.
Dissolution On 8 January 1943, Sisak II was shut down, and the remaining child prisoners were sent to Zagreb. Over the course of its existence, a total of 6,693 Serb, Jewish, and Roma children passed through Sisak II, according to Bartrop and Grimm. White places the number of child inmates at 7,000. According to Bartrop and Grimm, between 1,160 and 1,500 children perished at the camp, largely as a result of
typhus. White estimates that between 1,200 and 1,600 children died from starvation, thirst, typhus and neglect. ==Legacy==
