Unaware how close he had come to victory, Vitiges ordered the cutting of all ten aqueducts to Rome, which for more than a millennium had supplied public fountains, plumbing, and the hydraulic mills that made the city’s flour. Belisarius improvised by using the rivers that ran through the city to power the mills—ensuring a constant supply of flour and bread—and braced for the next attack. Vitiges had constructed huge towers to breach the Roman walls, and a few weeks later he put them into action. The fighting was desperate as the Goths attacked two sections of the wall simultaneously. Time and again they came within inches of overwhelming the defenders, but Belisarius seemed to be everywhere at once, firing arrows from the walls and hacking at the scaling ladders. By the end of the day, more than thirty thousand Goths were dead, and Vitiges’ towers lay in a smoking ruin. Looking out over the walls, however, it was hard to see a dent in the waves of enemy soldiers. Belisarius knew that he would be hard-pressed to defend further attacks of this kind and hastily wrote to Justinian asking for reinforcements.
This wasn’t the first time that the general had written requesting more men, and, at first, Justinian simply ignored him. Belisarius had humbled Africa with a mere handful of men, repeatedly performing miracles of improvisation to keep his campaigns going, and this caused the emperor to repeatedly underestimate the men and materials needed to retake Italy. But there was something else, a dim flicker of uneasiness in his queen, a gnawing fear that things were not quite what they seemed. Theodora began to suspect that the constant calls for a larger army were merely a ruse. Surely these barbarian opponents could be vanquished with the troops available. Perhaps the general was preparing to turn the sword against the master. The emperor finally sent a few thousand reinforcements, but Theodora remained suspicious. This general would need careful watching.
The new men tipped the balance in favor of Belisarius, and the general soon felt secure enough to go on the offensive. In the medieval world, siege warfare was often worse on the invading army than on the besieged. Exposed to the elements, running short of food, and trying to avoid sickness in unsanitary conditions, Vitiges was fighting a losing battle, and he knew it. Even the land he was encamped on seemed exhausted. It had long ago turned to a sea of mud, and his men were forced to wander farther and farther away in search of food. This left them dangerously vulnerable to counterattack, and each successful raid dented their spirits.
The mood in the Gothic camp wasn’t improved when Vitiges got word that a Byzantine advance force had managed to slip out of Rome and capture the town of Rimini, only thirty-three miles from Ravenna. This entire struggle had been a vast exercise in futility for the Gothic king, and having his new capital in danger was the last straw Cursing the winds that brought such an enemy to Italy, the disgusted king gave the order to retreat. Not even then, however, were the Goths allowed to leave in peace. Somehow guessing the timing of the withdrawal, Belisarius came roaring out from behind his walls and inflicted a thoroughly humiliating rout on Vitiges’ panicked forces.
As the last Goth fled, he could perhaps have consoled himself with the fact that Italy hadn’t seen a man of Belisarius’s character since Hannibal had crossed the Alps more than seven hundred years before. With only a few thousand men, the Byzantine general had taken on a kingdom that numbered in the hundreds of thousands and managed to cripple its fighting ability within two years. In five years, with scarcely more men, he had subdued Africa and Italy and bent them to the imperial will.
Given a proper army and a little trust, there was no telling what Belisarius would have been able to do. The conquests of Spain and Gaul were tantalizingly within his reach; perhaps the Western Empire itself could be revived. With the imperium thus restored, Europe would have been spared the ravages of the Dark Ages, or at least the intensity of their destruction.
Unfortunately for the empire, it was never to find out. The brilliance of the general’s success had planted seeds of jealousy and distrust in the mind of Theodora, and there they were about to bear a bitter harvest. Belisarius was too young, too talented, and far too popular to be trusted.
When Justinian received yet another letter asking for reinforcements, he sent seven thousand troops and a man named Narses to keep an eye on his brilliant general. Already in his mid-sixties, Narses was the perfect candidate for the job. Indisputably the most powerful figure at court, he was the same eunuch who had helped Belisarius put down the Nika revolt, and he could be implicitly trusted because his condition prevented him from gaining the throne himself.
