 But in 1167, King Stephen refused to give Manuel control of the former Byzantine territories allocated to Béla-Alexios as his appanage; this directly led to the war that ended with the Battle of Sirmium.In 1167, bad health prevented Manuel from taking to the field in person, therefore he appointed his nephew Andronikos Kontostephanos, the "Megas Doux", to the command of his field army, with orders to bring the Hungarian army to battle.During the early summer of 1167, the Byzantine army under Andronikos Kontostephanos managed to bring a large Hungarian force to battle near Sirmium.
