The Savior Generals: How Five Great Commanders Saved Wars That Were Lost—From Ancient Greece to Iraq (12 page)

Belisarius initially had been sent only to arrest Hypatius, but on his own initiative he had become the first of the three loyal generals to attack the rioters. That unexpected act in itself probably broke the rebellion. The soldiers’ daring had saved Justinian and guaranteed Belisarius preeminence among Justinian’s generals. Now a master of court politics, the newfound hero married Antonia, a lowborn libertine twenty years his elder with a number of children. She was not only a court insider, but also an intimate of the empress Theodora.

Which of the two women in the lurid history of Procopius appears the more cruel and depraved? It did not matter—Antonia’s savvy and her intimacy with the empress cemented the previous natural affinity of the general and his emperor. In the end, Antonia proved a lifelong political partner with her far younger husband in what the historian Edward Gibbon famously called “a manly friendship.”

The young Belisarius may have lost three of four battles on the eastern border. He may have failed to achieve a clear strategic victory over the Persians. But after the Nika
riots he had proved absolutely loyal to his emperor—and shrewd about the relationship of military power to popular support. Moreover, as a Latin speaker and native of a more western province, Belisarius was an ideal commander to recapture the old Latin northern coast of Africa, and anything beyond that his emperor might envision.

Thus in June 533 the young Belisarius was entrusted by Justinian with his third great mission and set sail for Tunisia, with his new wife, Antonia, and his personal secretary, the court insider and soon-to-be historian Procopius. He was probably no more than thirty, but he already had earned a reputation as Constantinople’s fireman, the first military responder to the empire’s inevitable next conflagration.

Throughout the fifth century, a succession of Germanic Huns, Visigoths, and Ostrogoths had overrun much of Roman western Europe as they picked off the western and northern provinces of the empire. Yet none of these northern barbarian invasions had proven as terrifying to the residents of an eroding Roman Empire as the onset of the Vandals. With not much more than a hundred thousand tribesmen, swift-moving Vandal forces had savagely swept southward and westward from their homes in modern-day eastern Germany and Poland. After migration west along the Danube in the early fifth century, the Vandals crossed the Rhine, ravaged Gaul, and settled in the Iberian Peninsula before, under their leader Genseric, swarming southward across the Mediterranean into the old Roman provinces of North Africa. If the warm southern Mediterranean was an odd place for such northern European tribes to settle, nonetheless by 439 they had taken Carthage and de facto ended Roman government in much of the old domains of Mauretania, Africa, Numidia, and Cyrenaica—parts of modern-day Morocco, Algeria, Tunisia, and Libya that for much of the fourth and the early fifth centuries had been considered immune from the more distant Germanic invasions.

The Vandals—their purported propensity for wanton destruction gave us the later noun “vandalism”—were most infamous for their sack of Rome in 455, and for the failure of any subsequent Roman or indigenous Moorish force for a century to root them out of Africa. Unlike other Germanic and Slavic tribes, the Vandals exiled or murdered most
elite Roman landowning citizens. They focused on piracy and raiding rather than expanding agriculture and commerce, and either forcibly converted most Catholics in North Africa to their own heretical Christian sect of Arianism—or killed them. Whether it was true or not, in the Roman mind, the Vandals were far more destructive than the Goths and had shown little inclination to resurrect the veneer of Roman culture under their domain.

In 468 the Vandals had destroyed a large eastern Roman fleet that had attempted to reclaim North Africa. From that time on, they were given their due from Byzantium, which had no desire to lose thousands in another hopeless war against such a murderous tribe. However, by the time of Justinian, after a century of pillage, Vandal kings recognized that their numbers were too small to guarantee their own security in the face of hostile Moorish tribes to the south and the establishment of Gothic kingdoms across the Mediterranean. They had done well enough pillaging and ending centuries of Roman rule, evading both Roman and then Gothic punitive pursuit. But as the booty ran out, the parasitic Vandals had not been able to create anything in its place comparable to the system of Roman wealth creation and governance in Africa that they had drawn upon for a century.

As a result, the Vandal kings began to seek an uneasy peace with Constantinople—on the general promise of a newfound tolerance for Catholics in Africa and agreements to respect Roman order in the eastern Mediterranean. But when the pro-Byzantine Vandal king Hilderic (523–30) was dethroned in a coup, his cousin, the usurper Gelimer, renewed the persecutions. Soon the supporters of the deposed king appealed to Constantinople—at precisely the time Justinian was planning to reclaim at least some of the western provinces, if not in pursuit of his grandiose idea of a restored Roman Empire in the west. The emperor had a good casus belli, relative peace at his rear, a growing treasury, a silenced opposition, and a young, energetic general to conduct an invasion.

Yet the odds of success were still not encouraging. Once the armada entered the Mediterranean from the Aegean, the winds were largely unfavorable for westward sailing. The Byzantine fleet of some five hundred ships would have to land and supply an army among hostile populations more than a thousand miles from Constantinople. Even should Belisarius take back the Vandal capital at Carthage in modern-day Tunisia, he
might still have to hold the province against numerically superior indigenous Moorish tribesmen. The Visigoths in Spain and the Ostrogoth kingdom in Italy were at best neutral; yet more often both wished to see Byzantium weakened.

Nevertheless the general set sail in June 533, along with Antonia, Procopius, and a large force of seamen, infantry, and cavalry. The armada numbered perhaps forty-five to fifty thousand, although only twenty thousand were front-line combatants. Belisarius had learned much on the Persian border and during the riots at Constantinople—to show both force and mercy among civilian populations, and not rashly to commit his usually outnumbered and sometimes poorly disciplined multicultural forces to battle in unfavorable circumstances.
²⁷

Despite a difficult three-month voyage to Africa—contaminated bread and bad water sickened or killed hundreds on the voyage, and a diversion of part of the fleet to Sicily was necessary to restore supplies—Belisarius landed in early September 533 with his forces intact, about fifty or sixty miles east of the Vandal capital at Carthage. His plan was simple: Belisarius would march his forces methodically westward—no more than about ten miles per day—keeping the fleet in sight to protect his right flank and sending out his feared Hunnish cavalry on his left as he rallied the countryside against the Vandal king.
²⁸

As Belisarius began to march westward through the coastal towns, he ordered his men to spare the native African villages. Byzantines enlisted both the Moors and what was left of the old Roman landowning classes, in a promised liberation from Vandal savagery and the visions of a more enlightened renewal of the former imperial rule. Belisarius envisioned an insurgent campaign of winning over the countryside, or, as he put it, “This is the moment when moderation brings salvation, while lawlessness leads to death.” As a result he made a relatively uneventful march as “if in his own land.” In some sense, it seemed an absurdity that a Greek-speaking Byzantine army, more than a thousand miles from home, less than a year after near civil insurrection, and with an enemy restless on its eastern borders, would even attempt to overthrow the heretofore dreaded Vandal kingdom—or that anyone in the west would wish to join such an empire in chaos. Yet Belisarius approached Carthage as if he were leading a consular army at the zenith of Roman provincial power.
²⁹

The shocked Vandals were scrambling under their chieftain Gelimer to put up some sort of resistance with a somewhat smaller force of ten to
fifteen thousand, hoping to ambush Belisarius on the last leg of his march. They apparently anticipated that the Byzantine fleet would have to round Cape Bon out of sight of the army, where the coastal road crossed farther inland over hilly terrain to Carthage. Gelimer accordingly split his forces and assumed that once Belisarius descended into a low valley, he could be attacked front and rear from the mountains without hope of supplies or reinforcements from the fleet. Gelimer sent his nephew Giba-mund with two thousand cavalry to hit the slow-moving Byzantines on the flank. Then his brother Ammatas would block the enemy advance. The main body under Gelimer would finally follow Ammatas to finish the pincer movement, surround Belisarius, and destroy his column in familiar territory.

Ten miles outside Carthage, on September 13, 533, at Ad Decimum (“at the tenth milepost”), Belisarius carefully established a secure camp. He then dealt piecemeal with each successive Vandal contingent, careful not to dilute the strength of his main forces. The historian Procopius saw Belisarius’ genius in not deploying all his forces at the sight of each Vandal onslaught—together with the far too complex ambush of Gelimer—as largely responsible for the successive destruction of the various Vandal armies.

It was unwise for the Vandals, as a numerically inferior force, to trisect their strength in hopes of ambushing a larger column. Once the Vandal surprise attacks failed, there was nothing much left to block the steady advance of Belisarius on the capital. By day six of their march, the Byzantines were inside Carthage, repairing the ancient walls and preparing for a final battle against the reconstituted forces of Gelimer. In short, within a week of landing, Belisarius had accomplished what neither a Roman nor a Gothic force had been able to do in over a century—occupy the capital of the Vandal kingdom in North Africa. It was an example of blitzkrieg unmatched in the ancient world since the campaigns of Alexander the Great and Julius Caesar.

Now in Carthage, over the next three months, Belisarius sent emissaries to win over the local Latin-speaking population, the Moorish tribes, and Vandals still loyal to the previous regime of Hilderic. Gelimer, in response, was reinforced by his other brother, Tzazon. The latter had just put down a rebellion in Sardinia and arrived to join the recuperating Vandals. The brothers hoped to retake Carthage from the west. On December 15 they confronted the Byzantines with a much larger force at Tricameron, seventeen miles outside Carthage. Belisarius had lost
hundreds of his troops over the prior three months of firming up his occupation of the countryside. Now he was forced to station even more of his men to protect the captured towns from sporadic Vandal raids. So it is likely that some fifteen thousand Vandals under Gelimer at Tricameron may have initially outnumbered the Byzantine mounted force by perhaps five thousand or more.

Belisarius again deployed quickly and did not wait for the muster of his own infantry—cognizant of how the Vandals had fled at Ad Decimum when met with a sudden show of Byzantine nerve. The plan was for the heavy Byzantine cavalry on the wings to veer in and hit the Vandal center, after missile troops and horse archers had softened up the enemy, in hopes of breaking through before the Vandal flanks could surround Belisarius’ smaller force. After at least two heavy Byzantine mounted assaults, Tzazon fell. The Vandal center weakened and once more Gelimer panicked and fled the field. By the time the Byzantine heavy infantry finally arrived, the Vandals were already in full flight.

Over the next three months, Belisarius continued to root out the last vestiges of Vandal resistance in the west. He captured Gelimer and then finally was recalled to Constantinople—both to receive a triumph and to quash rumors that he wanted to set himself up as an independent strongman in a new African province. The emperor appreciated that Belisarius had established a clear pattern of winning generalship and seemed always to find a way to defeat Justinian’s enemies, from the Persian frontier, to the streets of Constantinople, to distant North Africa.

In his new style of provincial warfare, Belisarius felt he could make up for the chronic shortage of troops through audacity and winning over the local population—anticipating modern notions of counterinsurgency warfare in which an outnumbered invader must enlist local adherents to a shared cause. So-called barbarian forces, as Belisarius knew, were led by magnetic tribal leaders. When these charismatic strongmen were targeted and fell in battle, their armies usually dissipated. The key was not to use his signature heavy cavalry in reckless fashion in unplanned pursuits, but to hit the enemy hard and quickly through focused and concentrated jabs, destroying its morale before it could use greater numbers to outflank and surround the smaller expeditionary Byzantine forces. In contrast, either alienating the locals or in static fashion preparing for a large set battle was a prescription for disaster.

The Mediterranean world was stunned at the fall of Carthage. Belisarius had landed in North Africa in June 533. Less than seven months later, his army had destroyed the century-old Vandal kingdom in Africa, captured the usurper king Gelimer, either killed, enslaved, or recruited into his army most of the Vandal population, established a new Byzantine province that might provide a base for future conquests in the west—and sent waves of terror through the Gothic hierarchy in Italy that it might be next in line in Justinian’s apparent plan to pick off vulnerable provinces of the old Western Roman Empire. Byzantium was supposed to have followed the fate of Rome as a shrinking, corrupt populace gave way before hardier, growing, and more warlike tribes on its borders. Instead, Belisarius had somehow reversed the course of Mediterranean history and found a way for a small force of relatively affluent westerners to mold a successful expeditionary army of invasion against European tribesmen. As the general put it to his men before facing the Vandals, “Not by the number of men, and not by the measure of one’s body, but by the valor of the soul, war is decided.”
