But even this humiliating compact was not sufficient for the grasping avarice of Justinian. He required of Theodatus the surrender of his throne, which the latter promised; but before the compact could be carried into effect, he was driven from his throne, and Vittiges, a soldier of humble birth, but great energy and experience, was declared his successor. Establishing his head quarters at Ravenna, the Gothic king was making preparations to sustain his cause, when Belisarius, who had taken Naples, was invited to Rome by Pope Sylverius. Taking advantage of this opportunity, he immediately advanced, and triumphantly entered the “eternal city.”

Rome had now been under the dominion of its Gothic conquerors for sixty years, during which it had enjoyed the advantages of peace and prosperity. It had been the object of peculiar care, attention, and munificence, and had received the respect due to the ancient mistress of the world. Still, the people at large looked upon their rulers as foreigners and barbarians, and desired the return of the imperial sway, seeming to forget that they were preferring a foreign to a native government.

Belisarius lost no time in repairing the fortifications of Rome, while he actively extended his conquests in the southern parts of Italy. His military fame was now a host, and most of the towns submitted, either from a preference of the Byzantine government, or respect for the military prowess of the Roman general.

The great achievements of Belisarius strike us with wonder, when we consider the feeble means with which they were accomplished. His force at the outset of his invasion of Italy did not exceed 12,000 men. These were now much reduced by the bloody siege of Naples, and by his subsequent successes, which made it necessary to supply garrisons for the captured towns.

Vittiges, in his Adriatic capital, had spent the winter in preparations, and when the spring arrived, he set forth with a powerful army. Knowing the small force of Belisarius, he hurried forward towards Rome, fearing only that his enemy should escape by flight. The genius of Belisarius never shone with greater lustre than at this moment. By numerous devices he contrived to harass the Gothic army in their march, but owing to the flight of a detachment of his troops whom he had stationed at one of the towers, to delay their progress, they at last came upon him by surprise.

He was at the moment without the city, attended by only a thousand of his guards, when suddenly he found himself surrounded by the van of the Gothic cavalry. He now displayed not only the skill of a general, but the personal courage and prowess of a soldier. Distinguished by the charger whom he had often rode in battle—a bay with a white face—he was seen in the foremost ranks, animating his men to the conflict. “That is Belisarius,” exclaimed some Italian deserters, who knew him. “Aim at the bay!” was forthwith the cry through the Gothic squadrons and a cloud of arrows was soon aimed at the conspicuous mark. It seemed as if the fate of Italy was felt to be suspended upon a single life—so fierce was the struggle to kill or capture the Roman leader.

Amid the deadly strife, however, Belisarius remained unhurt; and it is said that more of the army fell that day by his single arm, than by that of any other Roman. His guards displayed the utmost courage and devotion to his person, rallying around him, and raising their bucklers on every side, to ward off the showers of missiles that flew with deadly aim at his breast. Not less than a thousand of the enemy fell in the conflict—a number equal to the whole Roman troop engaged in the battle. The Goths at length gave way, and Belisarius, with his guards, reentered the city.

On the morrow, March 12th, A. D. 537, the memorable siege of Rome began. Finding it impossible, even with their vast army, to encircle the entire walls of the city, which were twelve miles in length, the Goths selected five of the fourteen gates, and invested them. They now cut through the aqueducts, in order to stop the supply of water, and several of them, having never been repaired, remain to this day, extending into the country, and seeming like the “outstretched and broken limbs of an expiring giant.”

Though the baths of the city were stopped, the Tiber supplied the people with water for all needful purposes. The resources and activity of Belisarius knew no bounds: yet he had abundant occasion for all the advantages these could supply. The relative smallness of his force, the feebleness of the defences the fickleness and final disaffection of the people, the intrigues of Vittiges, and his vastly superior army constituted a web of difficulties which would have overwhelmed any other than a man whose genius could extort good from evil, and convert weakness into strength.

For a whole year, the encircling walls of Rome were the scenes of almost incessant attack and defence. The fertile genius of Vittiges suggested a thousand expedients, and the number as well as courage of his troops enabled him to plan and execute a variety of daring schemes. Yet he was always baffled by his vigilant rival, and his most elaborate devices were rendered fruitless by the superior genius of the Roman general. At last, on the 21st of March, A. D. 538, foreseeing that Belisarius was about to receive reinforcements, and despairing of success in the siege, Vittiges withdrew his army, suffering in his retreat a fearful massacre, from a sally of the Roman troops.
