Stephen, accompanied by his uncle Radivoj, duly set out for Serbia but narrowly escaped imprisonment during an Ottoman raid on the Bosnian royal residence of Bobovac. He arrived to Smederevo, capital of the Eastern Orthodox despotate, during the Holy Week of 1459, and ascended the Serbian throne on 21 March. Michael Szilágyi, regent for the underage King Matthias, arrived at the head of an army to ensure that command over the town's fortress would be assumed by Stephen without any difficulties.
