Osman was born into a family of South Slavic origin in Temeşvar, Temeşvar Eyalet. He spoke Serbian. Temesvár was inhabited by Romanians, Serbs and Hungarians, and had been conquered by the Ottoman Empire in 1552. Osman Aga was a low-ranking army officer in Temesvár. He excelled in learning foreign languages and equitation. After the unsuccessful siege of Vienna in 1683, the tide turned and the Holy League of European nations began forcing the Ottomans out of Hungary in the Great Turkish War between 1683–1699. In his works, he noted the "uprisal of the Serb rayah"; he mentioned that the Serbs of the region rose up when the Austrian general Valis took Segedin on October 20, 1686.
Military service
During the war, the Austrians were unable to capture Temesvár. But in 1688, Osman's squadron of 80 men was given a special task. They had to deliver the salaries of army officiers to Lipova, Arad, just to the north of Temesvár. While they were in Arad County, it was attacked by superior Austrian forces and the city council decided to surrender. Osman thus became a prisoner of war at the age of eighteen.
Prisoner of war
Osman Aga was awarded to a military judge in Austrian army who asked for ransom. Although he was able to pay for his freedom, he was not released. He was sold to several new masters in Kapfenberg and Vienna. He spent several months in dungeons and was frequently beaten or even whipped by his masters during the early years. But his skill in equitation and learning German helped him to live a relatively less stressful life in later years. One of his masters even offered him freedom in return for converting to Christianity, which he refused. After the Treaty of Karlowitz, he was able to return to Temesvár in 1700.
Austrian-Ottoman War and later life
In Temesvár, with the help of the German he had learned during his servitude, he became the official dragoman and served in several diplomatic missions to Austria. However his comfortable days were over at the outbreak of a new war between the Ottoman Empire and Austria in 1715. This time Eugene Savoy of Austria captured Temesvár in 1716. Osman Aga fled to Belgrade. But Belgrade shared the same fate in 1717. Shortly before the final assault of the Austrians on Belgrade, the Austrians were able to explode the ammunition dump of the fort on 14 August 1717 resulting in the death of some 3,000 people. Most of Osman's family members were among the 3,000. After the loss of Belgrade he served in Vidin and then came to Istanbul where he continued his civil service as dragoman.
Work
Osman Aga's most important work is Prisoner of the Infidels, which summarises his adventures in Austria between 1688 and 1700. He also wrote Austrian History, an unfinished work up to 1662. His other works include notes about his diplomatic missions after 1700.
