[1] Now this night, which was lighted by the gleam of no stars, we passed as is usual in difficult and doubtful circumstances, as fear prevented anyone from daring to sit down or to close his eyes in sleep. But no sooner had the first light of day appeared, than the glittering coats of mail, girt with bands of steel, and the gleaming cuirasses, scen from afar, showed that the king’s forces were at hand.

[2] Our soldiers, inflamed by this sight, since only a small stream separated them from the enemy, were in haste to attack them, but the emperor restrained them; however, a fierce fight took place not far from our very rampart between our outposts and those of the Persians, in which Machameus, general of one of our battalions, fell. His brother Maurus, later a general in Phoenicia, tried to protect him, and after cutting down the man who had killed his brother, he terrified all who came in his way, and although he was himself partly disabled by an arrow through his shoulder, by main strength he succeeded in bringing off Machameus, already pale with approaching death, from the fray.

[3] And when, because of the almost unendurable heat and the repeated attacks, both sides were growing weary, finally the enemy’s troops were utterly routed and fled in all directions. As we withdrew from the spot, the Saracens followed us for some distance but were forced to retreat through fear of our infantry; a little later they joined with the main body of the Persians and attacked with greater safety, hoping to carry off the Romans’ baggage; but on seeing the emperor they returned to the cavalry held in reserve.

[4] Leaving this region we came to an estate called Hucumbra, where contrary to our expectation we refreshed ourselves for two days, procuring everything that was useful and an abundance of grain; then we moved on after immediately burning everything except such things as time allowed us to carry off.

[5] On the following day, as the army was advancing more quietly, the Persians unexpectedly attacked the last division, which on that day chanced to have the duty of bringing up the rear, and would have slain them with little trouble, had not our cavalry, who were near by, quickly noticed this, and, spreading widely over the open valleys, prevented so great a disaster, inflicting wounds on those who came up with them.

[6] In this battle Adaces, a distinguished satrap, fell; he had once been sent as an envoy to the emperor Constantius and kindly received. The man who killed him brought his armour to Julian and received the reward which he deserved.

[7] On that same day the legions made complaint of the cavalry troop of the Tertiaci, on the ground that just as they themselves were forcing their way into the opposing lines of the enemy, the Tertiaci had gradually given way and so had damped the ardour of almost the entire army.

[8] At this the emperor was roused to righteous indignation, had their standards taken from them and their lances broken, and forced all those who were charged with running away to march with the packs, baggage, and prisoners; but their leader, who alone had fought bravely, was given the command of another troop, whose tribune was found guilty of having shamefully left the field.

[9] Also four other tribunes of the cavalry were dismissed for similar disgraceful conduct; for in view of the impending difficulties the emperor contented himself with this mild form of punishment.

[10] We then advanced for seventy stadia, while every kind of supplies grew less, since the grass and grain had been burned and every man had to snatch from the very flames whatever produce and fodder he could carry.

[11] Leaving this place as well, the whole army had come to a district called Maranga, when near daybreak a huge force of Persians appeared with Merena, general of their cavalry, two sons of the king, and many other magnates.

[12] Moreover, all the companies were clad in iron, and all parts of their bodies were covered with thick plates, so fitted that the stiff joints conformed with those of their limbs; and the forms of human faces were so skilfully fitted to their heads, that, since their entire bodies were plated with metal, arrows that fell upon them could lodge only where they could see a little through tiny openings fitted to the circle of the eye, or where through the tips of their noses they were able to get a little breath.

[13] Of these some, who were armed with pikes, stood so motionless that you would think them held fast by clamps of bronze. Hard by, the archers (for that nation has especially trusted in this art from the very cradle) ¹ were bending their flexible bows with such wide-stretched arms that the strings touched their right breasts, while the arrow-points were close to their left hands; and by a highly skilful stroke of the fingers the arrows flew hissing forth and brought with them deadly wounds.

[14] Behind them the gleaming elephants, with their awful figures and savage, gaping mouths could scarcely be endured by the faint-hearted; and their trumpeting, their odour, and their strange aspect alarmed the horses still more.

[15] Seated upon these, their drivers carried knives with handles bound to their right hands, remembering the disaster suffered at Nisibis; and if the strength of the driver proved no match for the excited brute, that he might not turn upon his own people (as happened then) and crush masses of them to the ground, he would with a mighty stroke cut through the vertebra which separates the head from the neck. For long ago Hasdrubal, brother of Hannibal, discovered that in that way brutes of this kind could quickly be killed. ²

[16] Although these sights caused no little fear, the emperor, guarded by troops of armed men and with his trustworthy generals, full of confidence, as the great and dangerous power of the enemy demanded, drew up his soldiers in the form of a crescent with curving wings to meet the enemy.

[17] And in order that the onset of the bowmen might not throw our ranks into confusion, he advanced at a swift pace, and so ruined the effectiveness of the arrows. ³ Then the usual signal for battle was given, and the Roman infantry in close order with mighty effort drove the serried ranks of the enemy before them.

[18] And in the heat of the combat that followed, the clash of shields, the shouts of the men, and the doleful sound of the whirring arrows continued without intermission. The plains were covered with blood and dead bodies, but the Persian losses were greater; for they often lacked endurance in battle and could with difficulty maintain a close contest man to man, since they were accustomed to fight bravely at long range, but if they perceived that their forces were giving way, as they retreated they would shoot their arrows back like a shower of rain and keep the enemy from a bold pursuit. So by the weight of great strength the Parthians were driven back, and when the signal for retreat was given in the usual manner, our soldiers, long wearied by the fiery course of the sun, returned to their tents, encouraged to dare greater deeds of valour in the future.

[19] In this battle (as was said) the loss of the Persians was clearly the greater, while that of our men was very slight. But noteworthy among the various calamities of the combats was the death of Vetranio, ⁴ a valiant fighter, who commanded the legion of the Zianni.
