Belisarius
Flavius Belisarius was a military commander of the Byzantine Empire under Emperor Justinian I. Belisarius was instrumental in the reconquest of much of the Mediterranean territory belonging to the former Western Roman Empire, which had been lost less than a century prior. He is considered one of the greatest military commanders of Byzantium and in history generally.
One of the defining features of Belisarius' career was his success despite varying levels of available resources. He is frequently cited as being among the "Last of the Romans". He conquered the Vandal Kingdom of North Africa in the Vandalic War in nine months and conquered much of Italy during the Gothic War. He also defeated the Vandal armies in the battle of Ad Decimum and played an important role at Tricamarum, compelling the Vandal king, Gelimer, to surrender. During the Gothic War, despite being significantly outnumbered, he and his troops recaptured the city of Rome and then held out against great odds during the siege of Rome.
After a setback at Thannurin, he won a battle against the Persians at Dara but was defeated at Callinicum. He successfully repulsed a Hunnic incursion at Melantias. He was also known for military deception; he repulsed a Persian invasion by deceiving their commander and lifted the siege of Ariminum without a fight.
Early life and career
Belisarius was born around the year 500, probably in Germania, a fortified town of which some archaeological remains still exist, on the site of present-day Sapareva Banya in south-west Bulgaria, within the borders of Thrace and Paeonia. He may have been born into an Thraco-Roman orIllyro-Roman family, but his ancestry is unknown. By 526, he had become a senior-level guardsman of Justinian, the nephew of Emperor Justin I. How he became one is unrecorded.
He was later given permission by the emperor to form a bucellarii regiment. It consisted of elite heavy cavalry that he later expanded into a personal household regiment, 7,000 strong. Belisarius' guards formed the nucleus of all the armies he would later command. Armed with lances, composite bows, and spatha, they were fully armoured to the standard of heavy cavalry of the day. A multi-purpose unit, these bucellarii were capable of shooting at a distance with bows, like the Huns, or could act as heavy shock cavalry, charging an enemy with lance and sword.
Iberian War
In his early career, Belisarius participated in multiple Byzantine defeats. In the first battle where he held an independent command he suffered a clear defeat. However, he and Sittas were noted as successful raiders, plundering Persian territory in the first invasion of Persarmenia of the war shortly before. The next battle was fought at Tanurin, where Belisarius played a leading role again. He fled with his troops after his colleagues were lured into a trap. His army was then defeated at Mindouos, but he was promoted shortly afterward, meaning he was not likely held responsible for the defeat. At first, he was likely a junior partner to some higher placed commander like Sittas, while at Thanurin there was no overall commander. Mindouos was probably the first battle in which he led the army entirely on his own.Following Justin's death in 527, the new emperor, Justinian I, appointed Belisarius to command a Roman army in the east, despite earlier defeats. In June/July 530, during the Iberian War, he led the Romans to a stunning victory over the Sassanids in the Battle of Dara. This victory caused the Persian king Kavad I to open peace negotiations with the Byzantines. At the battle Belisarius had dug trenches in order to direct the more mobile Sassanian force to a location where he could attack them from the rear, this was adopted from the Sasanians at Tanurin two years earlier.
On other fronts, the Byzantine forces were also winning. The Persians and their Arab allies, with a mobile force of 15,000 high-quality cavalry, invaded Byzantine lands again, now via Euphratensis, a route they had never taken before. Belisarius was taken by surprise and was unsure whether this was a feint or a real attack, so at first, he did not move. He called upon Roman-allied Arab tribes for help and received 5,000 troops. He forced the Persians to retreat with a successful strategic manoeuvre but he kept pursuing the fleeing Persians, reportedly because his soldiers threatened mutiny if no battle was fought. With 20,000 Byzantines and 5,000 Arabs he moved against the Persians, but he was defeated by Callinicum despite heavy numerical superiority, as the opposing commander, Azarethes, was a tactician as good as himself. Belisarius fled the field probably long before the fighting was over. This setback cost Justinian a chance to sign an early peace treaty as the shah regained confidence in the war effort. While the war went on after Dara and Callinicum, the death of the Persian shah, Kavad I, soon led to a peace treaty. The new shah, Khosrow, saw Justinian was anxious to sign for peace and thought he could quickly reach a favourable peace, such as the so-called eternal peace which heavily favoured the Persians. Belisarius was recalled to Constantinople and charged with incompetence and responsibility for the defeats at Thannuris and Callinicum, but after an investigation, he was cleared of the charges against him.
