Siege of Braničevo
Emperor Manuel's cousin, Andronikos Komnenos, who administered Belgrade, Braničevo, and Niš sent a letter to Géza II in 1154, offering to hand over those towns to him in exchange for his support against the emperor.[2] Although Andronikos' plot was discovered and he was captured, Géza II invaded the Byzantine Empire and laid siege to Braničevo fortress [sr] in late 1154.[5] As a Hungarian vassal, Borić, the ban of Bosnia took part in the attack, alongside a Bohemian detachment.[7] After hearing of the imprisonment of Andronikos, Géza II abandoned the siege and returned for Hungary.[8] Through Serdica (Sofia) and Niš, Manuel arrived in the Smilis province near Paraćin where he set up camp.
