In the meanwhile his general Adarman advanced from Babylon, traversed the desert, passed the Euphrates, insulted the suburbs of Antioch, reduced to ashes the city of Apamea, and laid the spoils of Syria at the feet of his master, whose perseverance, in the midst of winter, at length subverted the bulwark of the East. But these losses, which astonished the provinces and the court, produced a salutary effect in the repentance and abdication of the emperor Justin; a new spirit arose in the Byzantine councils; and a truce of three years was obtained by the prudence of Tiberius. That seasonable interval was employed in the preparations of war; and the voice of rumour proclaimed to the world that, from the distant countries of the Alps and the Rhine, from Scythia, Mœsia, Pannonia, Illyricum, and Isauria, the strength of the imperial cavalry was reinforced with 150,000 soldiers. Yet the king of Persia, without fear or without faith, resolved to prevent the attack of the enemy, again passed the Euphrates, and dismissing the ambassadors of Tiberius, arrogantly commanded them to await his arrival at Cæsarea, the metropolis of the Cappadocian provinces. The two armies encountered each other in the battle of Melitene; the barbarians, who darkened the air with a cloud of arrows, prolonged their line and extended their wings across the plain; while the Romans, in deep and solid bodies, expected to prevail in closer action by the weight of their swords and lances. A Scythian chief, who commanded their right wing, suddenly turned the flank of the enemy, attacked their rear-guard in the presence of Chosroes, penetrated to the midst of the camp, pillaged the royal tent, profaned the eternal fire, loaded a train of camels with the spoils of Asia, cut his way through the Persian host, and returned with songs of victory to his friends, who had consumed the day in single combats or ineffectual skirmishes. The darkness of the night, and the separation of the Romans, afforded the Persian monarch an opportunity of revenge; and one of their camps was swept away by a rapid and impetuous assault. But the review of his loss and the consciousness of his danger determined Chosroes to a speedy retreat; he burned, in his passage, the vacant town of Melitene, and, without consulting the safety of his troops, boldly swam the Euphrates on the back of an elephant. After this unsuccessful campaign, the want of magazines, and perhaps some inroad of the Turks, obliged him to disband or divide his forces; the Romans were left masters of the field, and their general Justinian, advancing to the relief of the Pers-Armenian rebels, erected his standard on the banks of the Araxes.
