Battle of Kruševac
Serbo-Hungarian victory The Battle of Kruševac was fought on October 2, 1454 between the forces of the Serbian Despotate, allied with the Kingdom of Hungary, and the Ottoman Empire.[3] In 1454 the Ottomans launched a major invasion against Serbia, at the helm of which was the Sultan himself, Mehmed the Conqueror.The siege was lifted when the Ottomans received reports of a relief force approaching under the command of John Hunyadi.[7] He left behind a powerful rear guard in Serbia under the command of Firuz Bey,[6] in anticipation of an attack on Ottoman territories by Hunyadi.[9] The victory at Leskovac allowed John Hunyadi and Đurađ Branković to decisively strike at the now isolated army of Firuz Bey, defeating it on the 2nd of October and capturing its commander,[8] after which they launched a major offensive, ravaging Niš and Pirot, and burning down Vidin in northern Bulgaria.
