Belisarius was among the finest generals of the age, the man who nearly won back the western Roman world for the emperor Justinian. With small, hard-fighting armies he beat the Persians in the east, destroyed the Vandal kingdom of North Africa and wrested much of Italy from the Goths. For all his victories he was mistrusted at court, and later ages remembered him as the last of the Romans1.
Dara and the Persian front
Belisarius rose to command young, on the eastern frontier against the Sasanid Empire of Persia. In 530, at Dara, he faced a much larger Persian army2 and won a careful defensive victory, digging a system of trenches that broke the2 enemy's attacks, a battle still studied for its use of ground. Two years later he was back in the capital, where he helped Justinian survive the1 Nika riots, a bloody uprising that nearly cost the emperor his throne.

The reconquest of Africa
In 533 Justinian sent Belisarius west with a small fleet3 to attack the Vandal kingdom of North Africa. In a lightning campaign he beat the Vandals at Ad Decimum, entered Carthage, then broke them again at Tricamarum and captured their king Gelimer1, restoring the rich province to the empire in barely a year. It was one of the swiftest conquests of the age.

The long war in Italy
Next came the greater prize: Italy, held by the Ostrogoths. Belisarius took Sicily, Naples and Rome, and held the old capital through a desperate year-long siege1 in 537 and 538. In 540 he entered Ravenna and captured the Gothic king.1 But the Gothic War dragged on for two decades and ravaged Italy, and Belisarius, recalled and given too few men, could never quite finish it.

The measure of the man
Belisarius served Justinian to the end, even leading the defence of Constantinople against a raid of Hunnic horsemen in 5594, yet he was repeatedly suspected of disloyalty and stripped of honours. He died in 565. The medieval tale that he was blinded and left to beg in the streets is a later legend with no basis in fact1; what is true is that one of the empire's greatest generals was never fully trusted by the master he served so well.
