Murad rushed to help the besieged Turks, arriving in late May. Sigismund, who did not wish to fight the bigger army, finalised a treaty by early June. Once part of the Hungarian army had withdrawn to the far side of the river, however, the Turkish commander Sinan Bey attacked their rear, capturing and killing those who remained, among them the Polish knight Zawisza Czarny. Sigismund was nearly caught with the rest of his army; however, Cecília Rozgonyi intervened, and she was solely responsible for his rescue. Sigismund then granted a hereditary right to Golubac to Cecilia and her brothers. During this and other fights resulting from Stefan's death, southern and eastern Serbia, including the Monastery of Daljša near Golubac, suffered heavily. It was after this fighting, however, that Sigismund was first referred to as "our Emperor", in the memoir of a Daljšan monk, in contrast to the Turkish "pagan emperor". The Ottoman Empire retained control of Golubac throughout its occupation of the Serbian Despotate. After years of fighting, which resulted in the Hungarian army expelling the Ottomans from Serbia, the Peace of Szeged restored the Despotate late in the summer of 1444. Included in the redefined territory, after much discussion, was Golubac Fortress. However, the Turks once again conquered it after the death of Đurađ Branković in 1456. In 1458, Matthias Corvinus of Hungary regained the fortress, but lost it to Mehmed II that same year. The years 1481–82 led to more fighting between the Hungarians and Turks. During the fall of 1481, while Golubac was held by the Ottoman Empire, Timișoaran Comes Pál Kinizsi undertook an expedition against the Turks in the Temes area. On November 2, 1481, he turned his army of 32,000 men south towards the Danube, pushing to Kruševac. At Golubac, a thousand Turkish cavalry were killed or taken prisoner, 24 ships were sunk, and Mihaloğlu İskender Bey, pasha of Ottoman-held Smederevo and leader of the Turkish army, was beheaded at the gate by Jakšić, one of Kinizsi's men. The Turks were forced to retreat and leave the fortress behind. Kinizsi's foray was only a raid, however, and shortly after he returned to Temes. The Turks, who had suffered heavily but did not lose any land, retook Golubac and quickly improved its fortifications. Modern era Golubac was held by the Habsburg monarchy between 1688 and 1690 and 1718 and 1739. Serb rebels controlled it during Kočina
