Sokollu Mehmed Pasha had all witnesses to the Sultan's death executed, and announced that Suleiman was too sick to perform his duties and that he would be healing in Szigetvár, while he would be acting on the Sultan's behalf. Sokollu Mehmed rewarded those involved in the capture of Szigetvár and increased the soldiers' wages. He sent a part of the army to capture Babócsa. The Tartars, however, spread the news of the Sultan's death, and Sokollu Mustafa Bey wrote to Prince Selim about his father's death. Selim marched immediately towards Srem. Upon his arrival in Vukovar, Sokollu Mehmed wrote him that it would be best if he went to Belgrade to greet his army for a more formal and effective take-over of the Empire. Selim returned to Belgrade, and Mehmed ordered the army to march towards the town. Forty days after the Sultan's death, in October 1566, the army set out for Belgrade. At the fourth stop on the way to Belgrade, forty-eight days after Suleiman's death, Sokollu Mehmed announced the Sultan's death ceremonially, during the traditional reading of the Koran. Sokollu Mehmed had Suleiman's body embalmed and ordered the army to proceed to meet the new Sultan in Belgrade. After three marches, the army arrived in Sremska Mitrovica. Mehmed reminded Selim to send gifts to the viziers, pashas and the army, but Selim's advisors convinced the new Sultan not to do so. Sokollu Mehmed went to Belgrade and swore allegiance to Selim II as his Sultan, and Selim confirmed him as his Grand Vizier.
