Witiges laid siege to Rome with an army said by Procopius
In spite of the prudent arrangements adopted by Belisarius to insure supplies of provisions from his recent conquests in Sicily and Africa, Rome suffered very severely from famine during the siege; but the Gothic army was compelled to undergo equal hardships, and suffered far greater losses from disease. The communications of the garrison with the coast were for a time interrupted, but at last a body of five thousand fresh troops and an abundant supply of provisions, despatched by Justinian to the assistance of Belisarius, entered Rome. Shortly after the arrival of this reinforcement, the Goths found themselves constrained to abandon the siege, in which they had persevered for a year. Justinian again augmented his army in Italy, by sending over seven thousand troops under the command of the eunuch Narses, a man whose military talents were in no way inferior to those of Belisarius, and whose name occupies an equally important place in the history of Italy. The emperor, guided by the prudent jealousy which dictated the strictest control over all the powerful generals of the empire, had conferred on Narses an independent authority over his own division, and that general, presuming too far on his knowledge of Justinian’s feelings, ventured to throw serious obstacles in the way of Belisarius. The dissensions of the two generals delayed the progress of the Roman arms. The Goths availed themselves of the opportunity to continue the war with vigour; they succeeded in reconquering Mediolanum, which had admitted a Roman garrison, and sacked the city, which was second only to Rome in wealth and population. They massacred the whole male population, and behaved with such cruelty that three hundred thousand persons were said to have perished—a number which probably only indicates the whole population of Mediolanum at this period.
Witiges, finding his resources inadequate to check the conquests of Belisarius, solicited the aid of the Franks, and despatched an embassy to Chosroes to excite the jealousy of the Persian monarch. The Franks, under Theodebert, entered Italy, but they were soon compelled to retire; and Belisarius, being placed at the head of the whole army by the recall of Narses, soon terminated the war. Ravenna, the Gothic capital, was invested; but the siege was more remarkable for the negotiations which were carried on during its progress than for the military operations. The Goths, with the consent of Witiges, made Belisarius the singular offer of acknowledging him as the emperor of the West, on condition of his joining his forces to theirs, permitting them to retain their position and property in Italy, and thus ensuring them the possession of their nationality and their peculiar laws.
Perhaps neither the state of the mercenary army which he commanded nor the condition of the Gothic nation rendered the project very feasible. It is certain that Belisarius only listened to it, in order to hasten the surrender of Ravenna and secure the person of Witiges without further bloodshed. Italy submitted to Justinian, and the few Goths who still maintained their independence beyond the Po pressed Belisarius in vain to declare himself emperor. But even without these solicitations, his power had awakened the fears of his sovereign, and he was recalled, though with honour, from his command in Italy. He returned to Constantinople leading Witiges captive, as he had formerly appeared conducting Gelimer.
