Vandalic War

• 1. Introduction

  ›

  The Vandalic War of 533-534 ended a century of lost Roman territory in a single year. In two decisive battles fought just months apart, the Byzantine general Belisarius shattered a Germanic kingdom that had humiliated Rome itself, sacked the eternal city, and defeated the combined forces of both Roman empires. The questions that hang over this astonishing campaign are not simply military. How did a relatively small expeditionary force undo a kingdom that had held North Africa for nearly a hundred years? Why did Gelimer, with an army of tens of thousands, fall to a general he had never faced? And what did victory actually mean for the people of North Africa who lived through it?

  In May 429, the Vandalic king Geiseric crossed the Straits of Gibraltar with his entire people, reportedly 80,000 in total. He had been invited by Bonifacius, the Roman governor of the Diocese of Africa, who needed military support against the western emperor Valentinian III. What Bonifacius got was not an ally but a conqueror. By October 439, Geiseric had taken Carthage itself, the capital of Africa, and made it his own.

  The Vandals remade everything they touched. Unlike the Germanic kings of western Europe, who continued minting coins with the emperor's portrait and deferring to Roman political forms, the Vandal kings portrayed themselves as fully independent rulers. They kept their own language, maintained their own dress to emphasize their position as the kingdom's elite, and practiced the Arian form of Christianity, which put them in direct religious conflict with the Chalcedonian majority of the Roman-African population.

  Geiseric's ambitions did not stop at the African coast. His fleet raided as far as the Aegean Sea. In 455, his forces sacked Rome itself, a looting that allegedly lasted two weeks. He also seized Sardinia, Corsica, and the Balearic Islands, and his fleet scattered or captured a western emperor's armada off the coast of Spain in 460 before it could even set sail. In 468, he defeated a huge joint expedition by both western and eastern empires under the commander Basiliscus, the single greatest Roman naval effort of the century. The eastern emperor Zeno concluded a "perpetual peace" with Geiseric in 474-476.

  After Geiseric died in 477, relations with Constantinople gradually normalized, though the religious persecution of the Chalcedonian population flared under kings Huneric and Gunthamund. The shift that truly changed the trajectory of the kingdom came in 523, when Hilderic, a descendant of Valentinian III, took the throne. Procopius describes him as unwarlike and amiable. He stopped the persecutions, exchanged gifts and embassies with the future emperor Justinian I before Justinian had even risen to power, and in a striking symbolic move, replaced his own image on his coins with that of the emperor. Justinian evidently hoped this rapprochement would lead to a peaceful subordination of the Vandal state.

• 3. The Pretext and the Plan

  ›

  A defeat in Byzacena against the Mauri chief Antalas of the Frexes tribe gave Gelimer the excuse he had been looking for. In 530, he staged a palace coup in Carthage, overthrew Hilderic, and imprisoned him. Justinian demanded Hilderic's restoration, and when Gelimer refused, demanded at least that Hilderic be released to Constantinople. Gelimer refused that too, arguing it was an internal Vandal matter. He was probably right that war was coming regardless: as the historian J.B. Bury reasoned, he was unlikely to hand a rival claimant to an emperor who could use him as a tool.

  Justinian had his pretext. With peace secured on his eastern frontier with Sassanid Persia in 532, he began assembling an invasion force. The news, according to Procopius, caused great consternation among Constantinople's elites, in whose minds the disaster of 468 was still fresh. The empire's financial officials resented the expenditure. The military was weary from the Persian war and feared the Vandals' sea power. Only the powerful minister John the Cappadocian openly voiced his opposition, and Justinian disregarded it.

  Before the fleet sailed, Justinian worked the diplomatic angles. Two revolts conveniently destabilized the Vandal kingdom from within: one in Sardinia, where the governor Godas declared himself an independent ruler, and one in Tripolitania, where a man named Pudentius led the native population against Vandal rule. Both Godas and Pudentius immediately requested help from Justinian. The historian Ian Hughes notes that both rebellions broke out shortly before the Roman expedition began and that both rebel leaders asked Constantinople for support, which he takes as evidence of active imperial involvement in their preparation.

  Gelimer responded to Godas' revolt by sending the bulk of his fleet, 120 of his best vessels, and 5,000 men under his brother Tzazon to Sardinia. This decision would prove catastrophic. It removed the Vandal navy from African waters, eliminating the main obstacle to a Roman landing, and stripped the kingdom of a substantial portion of its army. Meanwhile, Justinian secured the benevolent neutrality of the Ostrogothic Kingdom of Italy, whose court bore the Vandals ill will over the mistreatment of an Ostrogothic princess named Amalafrida. The Ostrogoths agreed to let the Roman fleet use the harbour of Syracuse for provisioning.

• 4. Belisarius and His Army

  ›

  Justinian selected Belisarius to lead the expedition. The choice was based on more than his recent victories against the Persians and in suppressing the Nika riots. Ian Hughes points out two additional qualities that made Belisarius uniquely suited: he was a native Latin-speaker, and he was solicitous of the welfare of local populations, maintaining tight discipline over his troops. Both qualities mattered enormously in winning over a Latin-speaking African population that had lived under Vandal rule for a century.

  The army that boarded the fleet in late June 533 consisted, according to Procopius, of 10,000 infantry and 5,000 cavalry, supplemented by 1,500 to 2,000 of Belisarius' own elite retainers called bucellarii, along with 600 Huns and 400 Heruls as allied mounted archers. The whole force was transported on 500 vessels manned by 30,000 sailors under the admiral Calonymus of Alexandria, protected by ninety-two dromon warships. J.B. Bury considered this force remarkably small for the task, suggesting it may have reflected either the fleet's carrying limits or a deliberate choice to limit the cost of any potential defeat. Hughes took a different view, arguing the army was a large, well-balanced force that likely contained a higher proportion of high-quality troops than the eastern armies.

  Against this force, the Vandal army presented a structural mismatch. Every able-bodied Vandal male was expected to fight, making estimates of their strength dependent on total population figures that historians dispute, ranging from roughly 20,000 to 40,000 men. More critically, the Vandal army was composed exclusively of cavalry, lightly armoured and trained only for hand-to-hand combat. They entirely neglected the use of bows or javelins, placing them at a stark disadvantage against Belisarius' heavily armoured cataphracts and horse archers. A century of prosperous life in Africa had also eroded the Vandals' martial sharpness. The army sailed from Constantinople around the 21st of June 533, with Justinian and the Patriarch of Constantinople in attendance at the departure ceremony.

• 5. The March and Ad Decimum

  The voyage was not without its costs. At Methone in Greece, 500 men died of dysentery caused by mouldy bread. Procopius attributed responsibility to John the Cappadocian, who had cut costs by baking it only once, causing it to go bad. Justinian was informed; John was not punished.

  At Catania in Sicily, Belisarius sent Procopius ahead to Syracuse to gather intelligence. By chance, Procopius met a merchant friend whose servant had just arrived from Carthage. The servant told him that the Vandals were entirely unaware of the fleet's sailing, and that Gelimer had left Carthage to stay at the small inland town of Hermione. Belisarius immediately ordered the army to re-embark. The fleet sailed by Malta and reached Cape Caputvada on the eastern shore of modern Tunisia, some 162 Roman miles south from Carthage, in early September.

  Belisarius was acutely aware of what his campaign required. On the day after landing, when some of his men stole fruit from a local orchard, he punished them and assembled the whole army, urging them to maintain discipline and restraint toward the native population. Procopius records that the soldiers responded, and that Belisarius "by displaying great gentleness and kindness, won the Libyans to his side so completely that thereafter he made the journey as if in his own land".

  On the 13th of September, the tenth day of the march from Caputvada, the Roman army approached Ad Decimum. Gelimer had devised a three-pronged encirclement: his brother Ammatas would block the Roman advance with forces from Carthage, his nephew Gibamund would strike the left flank with 2,000 men, and Gelimer himself would hit from the rear with the main army. The plan nearly worked. But the three forces failed to synchronize. Ammatas arrived early, attempted a reconnaissance with a small force, and was killed by the Roman vanguard. Gibamund's detachment was intercepted and destroyed by the Hunnic flank guard, with Gibamund killed. Gelimer, unaware of both disasters, advanced and scattered the Roman forces at Ad Decimum. Victory was within reach. Then he came upon his dead brother's body and, as Procopius records, apparently forgot about the battle entirely. Belisarius used the interval to rally his cavalry and rout the disorganized Vandals. Carthage lay open.

• 6. Carthage and Tricamarum

  ›

  Carthage had thrown open its gates and lit the city in celebration, but Belisarius, wary of ambushes in the darkness, refused to enter on the night of the 14th. On the morning of the 15th of September, he led his army in. The Roman soldiers received a warm welcome. Belisarius himself sat on Gelimer's throne and ate the dinner the Vandal king had ordered prepared for his own victorious return.

  Gelimer withdrew to Bulla Regia, where he distributed money to build local loyalty and sent for Tzazon to return from Sardinia, where the Vandal force had successfully suppressed Godas' revolt and killed him. As Gelimer regrouped, most of the Mauri tribes of Numidia and Byzacena sent embassies to Belisarius, pledging allegiance to the empire and requesting the traditional insignia of office, including a gilded silver staff, a silver crown, a white cloak, a white tunic, and a gilded boot. Justinian had anticipated this and sent Belisarius the necessary items.

  In mid-December, Belisarius marched out of Carthage toward the Vandal fortified camp at Tricamarum, some 28 km from the city. The battle that followed was almost entirely a cavalry affair, with Belisarius' army considerably outnumbered. John the Armenian led repeated charges at the Vandal centre until Tzazon was killed. The Vandal line collapsed. Gelimer fled with a few attendants into Numidia. The remainder of his army abandoned their camp.

  J.B. Bury's assessment is instructive: the expedition's fate might have been quite different "if Belisarius had been opposed to a commander of some ability and experience in warfare". Procopius himself, Bury notes, "expresses amazement at the issue of the war, and does not hesitate to regard it not as a feat of superior strategy but as a paradox of fortune".

  Gelimer retreated first to Hippo Regius and then to a mountain stronghold called Medeus on Mount Papua, where he relied on the local Mauri population for shelter. Belisarius sent 400 men under the Herul Pharas to blockade him. Pharas grew impatient over the winter, attacked the mountain position, and was beaten back with the loss of a quarter of his men. It was not until March that Gelimer agreed to surrender, having received guarantees for his safety.

• 7. The Triumph and Its Limits

  ›

  Belisarius returned to Constantinople with Gelimer, large numbers of captured Vandals, and the Vandal royal treasure. That treasure included many objects looted from Rome 80 years earlier, among them the imperial regalia and the menorah of the Second Temple, which Titus had brought to Rome after the capture of Jerusalem. The Vandals captured in the campaign were enrolled in five regiments called the Vandali Iustiniani.

  In Constantinople, Belisarius was given the honor of a triumph. Procopius describes Gelimer being paraded through the hippodrome, wearing purple, until he reached the emperor's seat. Seeing Justinian on his raised throne and the crowd surrounding him, Gelimer neither wept nor cried out but repeated a verse from the Hebrew scriptures: "Vanity of vanities, all is vanity." He was then forced to prostrate himself before the emperor. Belisarius did the same, as a gesture of submission alongside his captive. Gelimer was afterward given an estate in Galatia and would have been raised to the rank of patrician, but refused to renounce his Arian faith. Belisarius was named consul ordinarius for 535 and celebrated a second procession, carried through the streets on his consular chair, held aloft by Vandal warriors.

  In Africa itself, Justinian moved swiftly to erase the Vandal conquest. Vandals were barred from holding office or property. Most Vandal males became slaves. The Chalcedonian Church was restored while the Arian Church was dispossessed. Already in April 534, before Gelimer had even surrendered, the full apparatus of Roman provincial administration had been restored under a praetorian prefect. An extensive fortification program followed, and Carthage's ports were redeveloped, a fact confirmed by Procopius. Archaeological excavations at the port city of Leptiminus have yielded evidence of major imperial investment in amphora production and iron working.

  But the pacification of Africa was not complete. The Mauri tribes of the interior had never been under firm Vandal control, and they were no more amenable to Roman authority. Solomon, the first imperial governor and Belisarius' former chief of staff, scored early successes but was overtaken by a widespread military mutiny in 536. He returned to power in 539 but fell in the Battle of Cillium in 544. Instability persisted, worsened possibly by the arrival of plague in North Africa in 543. It would not be until 548 that the general John Troglita finally broke Mauri resistance, a feat credited by the poet Corippus among others. Procopius, writing in his later work the Secret History, offered a far harsher assessment of what the reconquest had actually delivered to ordinary North Africans, describing not triumph but ruined lives and the complexities of a corrupt and contested occupation.
