Encouraged by Matthias's commitment to help and possibly by the Bishop of Modruš, Stephen Tomašević made an imprudent and fatal decision in June 1462. Pope Pius wrote in his diary that, "relying on one knows what hope", the King "refused the tributes which his ancestors had long been used to pay the Ottomans and had stormed the town which the enemy had built at the confluence of Sava and Bosna to put fear into the Hungarians and Slavs." According to Chalkokondyles, Stephen invited the Ottoman ambassador to his treasure house and showed him the money set aside as tribute, but informed him that he would rather use it to fight off an Ottoman attack or to live off it in exile. Mehmed the Conqueror was enraged by Stephen's insubordinance and audacity. The Pope recounts how, hearing of the Sultan's vow to conquer his kingdom and destroy him, Stephen summoned the Bishop of Modruš and blamed him for infuriating the Sultan. He commanded Nicholas to go to Hungary and seek immediate action against the Ottomans, but no help ever arrived to Bosnia from Christendom. Matthias, Skenderbeg and the Ragusans all failed to carry out their promises.
