The Crusaders, numbering 22,000–30,000,[10][11][12][13] arrived at Kosovo Field – the site of the first Battle of Kosovo in 1389, between Serbs and Ottomans – and faced an Ottoman army of up to 60,000.[13][11] Sultan Murad personally commanded a large section of cannons and janissaries, while his son and would-be successor, 16-year-old Mehmed, who faced battle for the first time, led the Anatolian troops at the right wing. Hunyadi commanded the center of his army in the battle, while the Crusaders right wing was under the Wallachians.
