At the Battle of Niš (Battle of Nissa) (early November, 1443), crusaders led by John Hunyadi, captured Ottoman stronghold Niš and defeated three armies of the Ottoman Empire. The Battle of Niš was part of Hunyadi's expedition known as the long campaign. Hunyadi, at the head of the vanguard, crossed the Balkans through the Gate of Trajan, captured Niš, defeated three Turkish pashas, and, after taking Sofia, united with the royal army and defeated Sultan Murad II at Snaim (Kustinitza). The impatience of the king and the severity of the winter then compelled him (February 1444) to return home, but not before he had utterly broken the Sultan's power in Bosnia, Herzegovina, Serbia, Bulgaria, and Albania.
