Sisak Fortress

The Battle of Sisak was fought on 22 June 1593 between Ottoman Bosnian forces and a combined Christian army from the Habsburg lands, mainly the Kingdom of Croatia and Inner Austria. The battle took place at Sisak, central Croatia, at the confluence of the Sava and Kupa rivers, on the borderland between Christian Europe and the Ottoman Empire. Between 1591 and 1593 the Ottoman military governor of Bosnia, Beglerbeg Telli Hasan Pasha, attempted twice to capture the fortress of Sisak, one of the garrisoned castles that the Habsburgs maintained in Croatia as part of the Military Frontier. In 1592, after the key imperial fortress of Bihać fell to the Turks, only Sisak stood in the way before Croatia's main city Zagreb. Pope Clement VIII called for a Christian league against the Ottomans, and the Sabor recruited in anticipation a force of about 5,000 professional soldiers. On 15 June 1593, Sisak was once again besieged by the Bosnian Pasha and his Gazis. The Sisak garrison was commanded by Blaž Đurak and Matija Fintić, both Croatian priests from the Diocese of Zagreb. A Habsburg relief army under the supreme command of the Styrian general Ruprecht von Eggenberg, was quickly assembled to break the siege. The Croatian troops were led by the Ban of Croatia, Tamás Erdődy, while major forces from the Duchy of Carniola and the Duchy of Carinthia were under the commander of the Croatian Military Frontier Andreas von Auersperg, known as the "Carniolan Achilles". On 22 June, the Austro-Croatian relief army launched a surprise attack on the besieging forces, and at the same time the garrison came out of the fortress to join the attack; the ensuing battle resulted in a crushing defeat for the Bosnian Ottoman army, with Hasan Pasha being killed in action and almost all of his army being wiped out. The battle of Sisak is considered the main catalyst for the start of the Long War which raged between the Habsburgs and the Ottomans from 1593 to 1606.

The Sisak concentration camp was a concentration and transit camp located in the town of Sisak, in the Axis puppet state the Independent State of Croatia (NDH), from 1941 to 1945, during World War II. It consisted of two sub-camps, Sisak I and Sisak II. The former was used to intern adults destined for forced labour in the Reich and was established in 1941, while the latter was used to detain unaccompanied Serb—and to a lesser extent, Jewish and Roma—children who had been separated from their parents over the course of the conflict. Sisak I was operated by the Germans, whereas Sisak II was administered by the Ustaše, with some German gendarmes guarding its perimeter. The latter became operational in July–August 1942, receiving a group of children who had previously been detained at Mlaka. Living conditions at the children's camp were poor, leading to a high mortality rate. According to survivors, some children were killed by being given poisoned milk or gruel laced with caustic soda. On other occasions, camp commander Antun Najžer administered children with lethal injections. Thousands of children were saved from the camp as a result of rescue efforts spearheaded by the humanitarian Diana Budisavljević and the local communist underground. Sisak II was dissolved in January 1943. The exact number of children who perished there is unknown, but estimates range from 1,160 to 1,600, largely as a result of starvation, thirst, typhus and neglect. In April 1944, the Germans ceded control of Sisak I to the Ustaše. It was shut down in January 1945 and its remaining inmates were dispatched to Jasenovac. In September 1946, Najžer was convicted for his involvement in the atrocities that took place at the children's camp and sentenced to death by firing squad. Memorials commemorating the camp victims were demolished by Croatian forces in the early 1990s, during the Croatian War of Independence. Camp survivor Gabrijela Kolar's sculpture was spared, but has since fallen into a state of disrepair. In post-independence Croatia, the camp's main building was transformed into a theatre and renamed the Crystal Cube of Cheerfulness.

Odra (pronounced [odra]) is a river in central Croatia. It is 83 km (52 mi) long and its basin covers an area of 604 km2 (233 sq mi). Its source is in the Žumberak mountain, southwest of Zagreb. It flows eastwards, passes south of Velika Gorica, then turns south-east, more or less parallel to the river Sava. It flows into the river Kupa near Odra Sisačka, just northeast of Sisak, also just before the Kupa joins the river Sava. The upper flow of Odra has been significantly altered by humans, by the digging of the 32 km (20 mi) long canal Sava-Odra(-Sava) south of Zagreb, as a measure against flooding (designed taking into account the maximum flows of 1964, 1973 and 1974, and first put to use in 1979). There is no certain etymology for the river's name, it could be Slavic or pre-Slavic, and 20th-century linguists did not have a consensus about it.
