Justinian sent another general, Narses, to Italy, but tensions between Narses and Belisarius hampered the progress of the campaign. Milan was taken, but was soon recaptured and razed by the Ostrogoths. Justinian recalled Narses in 539. By then the military situation had turned in favour of the Romans, and in 540 Belisarius reached the Ostrogothic capital Ravenna. There he was offered the title of Western Roman Emperor by the Ostrogoths at the same time that envoys of Justinian were arriving to negotiate a peace that would leave the region north of the Po River in Gothic hands. Belisarius feigned acceptance of the offer, entered the city in May 540, and reclaimed it for the Empire. Then, having been recalled by Justinian, Belisarius returned to Constantinople, taking the captured Vitigis and his wife Matasuntha with him.
