Belisarius entered the city after the departure of the Goths; and as he found it deserted, he had the greatest difficulty in putting it in a state of defence. But though Belisarius was enabled, by his military skill, to defend Rome against the attacks of Totila, he was unable to make any head against the Gothic army in the open field; and after vainly endeavouring to bring back victory to the Roman standards in Italy, he received permission to resign the command and return to Constantinople. His want of success must be attributed solely to the inadequacy of the means placed at his disposal for encountering an active and able sovereign like Totila. The unpopularity of his second administration in Italy arose from the neglect of Justinian in paying the troops, and the necessity which that irregularity imposed on their commander of levying heavy contributions on the Italians, while it rendered the task of enforcing strict discipline, and of protecting the property of the people from the ill-paid soldiery, quite impracticable. Justice, however, requires that we should not omit to mention that Belisarius, though he returned to Constantinople with diminished glory, did not neglect his pecuniary interests, and came back without any diminution of his wealth. [Sidenote: [547-553 A.D.]] As soon as Totila was freed from the restraint imposed on his movements by the fear of Belisarius, he quickly recovered Rome; and the loss of Italy appeared inevitable, when Justinian decided on making a new effort to retain it. As it was necessary to send a large army against the Goths, and invest the commander-in-chief with great powers, it is not probable that Justinian would have trusted any other of his generals more than Belisarius had he not fortunately possessed an able officer, the eunuch Narses, who could never rebel with the hope of placing the imperial crown on his own head. The assurance of his fidelity gave Narses great influence in the interior of the palace, and secured him a support which would never have been conceded to any other general. His military talents, and his freedom from the reproach of avarice or peculation, augmented his personal influence, and his diligence and liberality soon assembled a powerful army. The choicest mercenary troops--Huns, Herulians, Armenians, and Lombards--marched under his standard with the veteran Roman soldiers. The first object of Narses after his arrival in Italy was to force the Goths to risk a general engagement, trusting to the excellence of his troops and to his own skill in the employment of their superior discipline.
