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.
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.
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.
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.
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.
We then advanced for seventy stadia, while every kind of supplies grew less, since the grass
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.
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.
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)[*](The Persian boys from the age of five were taught to ride, to use the bow, and to speak the truth (Hdt. i. 136).) 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.
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
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.[*](Livy, xxvii. 49, 1 ff.)
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.
