Vandalic War
In May 429, King Geiseric led his entire people across the straits of Gibraltar into Roman North Africa. The group numbered approximately 80,000 individuals according to historical accounts. They arrived with a clear intent to conquer African provinces rather than seek aid as initially requested by the rebel governor Bonifacius. By October 439, the Vandals captured Carthage, establishing their capital and founding an independent kingdom. This new state replaced existing Roman socio-political structures entirely instead of maintaining them. The Vandals differentiated themselves from native Romano-African populations through distinct language use and peculiar dress codes. Their adherence to Arianism led to persecution of the Chalcedonian majority during reigns of Huneric and Gunthamund. Despite these tensions, relations normalized after Geiseric's death in 477 following a perpetual peace agreement concluded around 474 or 476.
A palace coup occurred in Carthage in 530 when Gelimer overthrew pro-Roman Hilderic due to military defeats against Antalas of the Frexes tribe. Justinian seized this opportunity to demand Hilderic's restoration while Gelimer predictably refused. The Eastern Roman emperor had secured his eastern frontier with Sassanid Persia in 532 before beginning preparations for invasion under general Belisarius. Procopius recorded that news of war caused great consternation among Constantinople's elites who remembered the disaster of 468. Financial officials resented expenditures while military personnel feared Vandal sea power. Only John the Cappadocian openly opposed the expedition yet Justinian pressed forward regardless. Rebellions erupted simultaneously in Sardinia where Godas declared independence and Tripolitania where Pudentius led native resistance. Both uprisings requested assistance from Justinian suggesting active diplomatic involvement by the Emperor. Gelimer dispatched 120 vessels and 5,000 men under brother Tzazon to suppress Sardinian rebellion removing crucial naval forces from African waters.
The Byzantine fleet set sail around the 21st of June 533 with Justinian and Patriarch of Constantinople present at departure ceremonies. Initial progress slowed significantly as the fleet waited five days at Heraclea Perinthus for horses and four more days at Abydus due to lack of wind. Five hundred soldiers died of dysentery caused by mouldy bread baked only once by John the Cappadocian to cut costs. The army consisted of 10,000 infantry drawn partly from field armies and partly from foederati units plus 5,000 cavalry members. Additional forces included 1,500 to 2,000 bucellarii retainers alongside 600 Huns and 400 Heruls serving as mounted archers. Solomon served as chief staff while Archelaus managed provisioning operations. Rufinus the Thracian and Aïgan the Hun commanded cavalry divisions. Five hundred transport vessels carried thirty thousand sailors under admiral Calonymus of Alexandria protected by ninety-two dromon warships. Belisarius selected this force despite its relatively small size compared to Vandal military reputation. He maintained tight discipline over troops ensuring welfare of local populations which proved crucial for winning Latin-speaking African support.
On the morning of the 13th of September Roman forces approached Ad Decimum where Gelimer planned an ambush using three coordinated attacks. His brother Ammatas arrived early attempting reconnaissance with a small force but was killed by Roman vanguard before engaging main body. Nephew Gibamund led 2,000 men attacking left flank yet his entire force got intercepted and destroyed by Hunnic guards including Gibamund himself. Unaware of these failures Gelimer marched up with main army scattering Roman advance forces present at battlefield. Victory seemed possible until he discovered dead brother's body then forgot all about continuing battle entirely. This pause gave Belisarius time to rally remaining troops bringing up main cavalry force to defeat disorganized Vandals completely. Gelimer fled westward toward Numidia leaving Carthage undefended before advancing Roman army. The crushing victory ended first major engagement near capital city allowing Romans to occupy territory without immediate resistance. Only nightfall brought realization of full extent when John Armenian rejoined with six hundred Huns after spending night on battlefield itself.
Mid-December saw Belisarius march out of Carthage toward fortified Vandal camp located twenty-eight kilometers away at Tricamarum. Battle became purely cavalry affair despite Roman army being considerably outnumbered overall. Both sides kept most unreliable elements including Mauri tribesmen and Huns in reserve positions throughout fighting. John the Armenian played critical role leading repeated charges against Vandal center culminating directly in death of Tzazon during combat operations. General Roman attack across front line followed immediately causing complete collapse of Vandal army retreating back to their camp. Seeing total loss Gelimer fled with few attendants into wilds of Numidia while remaining Vandals abandoned thoughts of resistance entirely. They left camp to be plundered by Romans who had previously failed keeping forces together effectively. Dispersal after battle showed poor discipline within Roman ranks alongside command difficulties faced by Belisarius constantly. A detachment under John pursued fleeing king for five days nights until accident killed him allowing escape to Hippo Regius then Medeus mountain stronghold where Mauri inhabitants provided refuge. Blockade lasted through winter until March when Vandal king agreed surrender after receiving safety guarantees from Pharas commanding four hundred Herul troops.
Officers within Belisarius's army sent messengers claiming he intended establishing independent kingdom hoping personal advancement would follow such accusations. Justinian offered two choices: return to Constantinople or remain in Africa permanently. Capturing one messenger aware of slanders Belisarius chose immediate departure leaving summer months behind. He took Gelimer along with large numbers captured Vandans enrolled into five regiments called Vandali Iustiniani plus royal treasure including objects looted from Rome eighty years earlier. The Menorah from Second Temple accompanied imperial regalia back to capital city. First triumph celebrated since foundation occurred over five and a half centuries ago granted specifically to private citizen rather than emperor himself. Gelimer received ample estate in Galatia though refused patrician rank maintaining steadfast refusal renouncing Arian faith completely. Belisarius named consul ordinarius year 535 enabling second triumphal procession carried streets seated consular curule chair held aloft by Vandal warriors distributing largesse populace from war booty share. Roman control scarcely extended beyond old Vandal kingdom boundaries however peace restored government firmly established province formally as praetorian prefecture Africa. Imperial administration restored April 534 before surrender completion under magister militum regional duces overseeing garrison forces.
