Raid on Kruševac

King Sigismund of Hungary (reigned 1387–1437) pursued an effective, decades-long, fundamentally defensive policy in the Hungarian–Ottoman Wars.^[1] Following the defeat at Nicopolis in 1396, King Sigismund developed a new defense strategy. He aimed to create a buffer zone along the border between the Kingdom of Hungary and the Ottoman Empire, and also strengthened the existing system of banates on the southern border, which was closely linked to the developing system of border fortresses.^[2]

King Sigismund ordered Franko Tallóci, John Ország, and John Marczaly to lead a contingent of Hungarian, Polish, and Czech soldiers in a raid against Turkish territory in the summer of 1437. Ali Bey, the marcher lord of Vidin, assembled an Ottoman force to pursue and attack the Hungarian raiders. Due in part to the valiant and decisive actions of Franko Tallóci, the Ottoman force was routed, and the Hungarians pursued the retreating Ottomans, inflicting casualties where possible. The raid on Kruševac was the largest and most successful Hungarian incursion in many years. It penetrated more than 100 kilometers into enemy territory, inflicted multiple defeats, and crippled the Ottoman river fleet. The raid had two significant consequences. First, it marked the first major offensive undertaken by the Hungarians in years, demonstrating the potential effectiveness of such operations. Second, it provoked the anger of the Sultan at a time when other factors were already pushing the Ottomans toward the annexation of Serbia and the conquest of Hungary.^[3]
