Career Ostrogski began his military career under John I Albert, King of Poland. He took part in successful campaigns against the Tatars and the Grand Principality of Moscow. For his victory near Ochakiv against Mehmed I Giray's forces, he was awarded with the title of Grand Hetman of Lithuania. He was the first person to receive this title. However, during a war with Muscovy, he was defeated in the Battle of Vedrosha (1500) and held captive for three years. In 1503, he managed to escape and joined king Sigismund I the Old, who allowed him to retain his post as a hetman.
