Crassus

It is said that on that day Crassus did not make his appearance in a purple robe, as is the custom with Roman generals, but in a black one, and that he changed it as soon as he noticed his mistake; also that some of the standard-bearers had great difficulty in raising their standards, which seemed to be imbedded, as it were, in the earth.

Crassus made light of these things amid hurried on the march, compelling the men-at-arms to keep up with the cavalry, until a few of those who had been sent out as scouts came riding up and announced that the rest of their number had been slain by the enemy, that they themselves had with difficulty escaped, and that their foes were coming up to fight them with a large force and great confidence.

All were greatly disturbed, of course, but Crassus was altogether frightened out of his senses, and began to draw up his forces in haste and with no great consistency. At first, as Cassius recommended, he extended the line of his men-at-arms as far as possible along the plain, with little depth, to prevent the enemy from surrounding them, and divided all his cavalry between the two wings. Then he changed his mind and concentrated his men, forming them in a hollow square of four fronts, with twelve cohorts on each side.

With each cohort he placed a squadron of horse, that no part of the line might lack cavalry support, but that the whole body might advance to the attack with equal protection everywhere. He gave one of the wings to Cassius, and one to the young Crassus, and took his own position in the centre. Advancing in this formation, they came to a stream called Balissus, which was not large, to be sure, nor plentiful, but by this time the soldiers were delighted to see it in the midst of the drought and heat and after their previous toilsome march without water.

Most of the officers, accordingly, thought they ought to bivouac and spend the night there, and after learning as much as they could of the number and disposition of the enemy, to advance against them at day-break. But Crassus was carried away by the eagerness of his son and the cavalry with him, who urged him to advance and give battle, and he therefore ordered that the men who needed it should eat and drink as they stood in the ranks.

And before they were all well done with this, he led them on, not slowly, nor halting from time to time, as is usual on the way to battle, but with a quick and sustained pace until the enemy came in sight, who, to the surprise of the Romans, appeared to be neither numerous nor formidable. For Surena had veiled his main force behind his advance guard, and concealed the gleam of their armour by ordering them to cover themselves with robes and skins. But when they were near the Romans and the signal was raised by their commander, first of all they filled the plain with the sound of a deep and terrifying roar.

For the Parthians do not incite themselves to battle with horns or trumpets, but they have hollow drums of distended hide, covered with bronze bells, and on these they beat all at once in many quarters, and the instruments give forth a low and dismal tone, a blend of wild beast’s roar and harsh thunder peal. They had rightly judged that, of all the senses, hearing is the one most apt to confound the soul, soonest rouses its emotions, and most effectively unseats the judgment.
