Crassus laughed at it, and hastened their march, and compelled his infantry to keep pace with his cavalry, till some few of the scouts returned and told them that their fellows were slain and they hardly escaped, that the enemy was at hand in full force, and resolved to give them battle. On this all was in an uproar; Crassus was struck with amazement, and for haste could scarcely put his army in good order. First, as Cassius advised, he opened their ranks and files that they might take up as much space as could be, to prevent their being surrounded, and distributed the horse upon the wings, but afterwards changing his mind, he drew up his army in a square, and made a front every way, each of which consisted of twelve cohorts, to every one of which he allotted a troop of horse, that no part might be destitute of the assistance that the horse might give, and that they might be ready to assist everywhere, as need should require. Cassius commanded one of the wings, young Crassus the other, and he himself was in the middle. Thus they marched on till they came to a little river named Balissus, a very inconsiderable one in itself, but very grateful to the soldiers, who had suffered so much by drouth and heat all along their march. Most of the commanders were of the opinion that they ought to remain there that night, and to inform themselves as much as possible of the number of the enemies, and their order, and so march against them at break of day; but Crassus was so carried away by the eagerness of his son, and the horsemen that were with him, who desired and urged him to lead them on and engage, that he commanded those that had a mind to it to eat and drink as they stood in their ranks, and before they had all well done, he led them on, not leisurely and with halts to take breath, as if he was going to battle, but kept on his pace as if he had been in haste, till they saw the enemy, contrary to their expectation, neither so many nor so magnificently armed as the Romans expected. For Surena had hid his main force behind the first ranks, and ordered them to hide the glittering of their armour with coats and skins. But when they approached and the general gave the signal, immediately all the field rung with a hideous noise and terrible clamour. For the Parthians do not encourage themselves to war with cornets and trumpets, but with a kind of kettle-drum, which they strike all at once in various quarters. With these they make a dead, hollow noise, like the bellowing of beasts, mixed with sounds resembling thunder, having, it would seem, very correctly observed that of all our senses hearing most confounds and disorders us, and that the feelings excited through it most quickly disturb and most entirely overpower the understanding.
When they had sufficiently terrified the Romans with their noise, they threw off the covering of their armour, and shone like lightning in their breastplates and helmets of polished Margianian steel, and with their horses covered with brass and steel trappings.
Surena was the tallest and finest looking man himself, but the delicacy of his looks and effeminacy of his dress did not promise so much manhood as he really was master of; for his face was painted, and his hair parted after the fashion of the Medes, whereas the other Parthians made a more terrible appearance, with their shaggy hair gathered in a mass upon their foreheads after the Scythian mode. Their first design was with their lances to beat down and force back the first ranks of the Romans, but when they perceived the depth of their battle, and that the soldiers firmly kept their ground, they made a retreat, and pretending to break their order and disperse, they encompassed the Roman square before they were aware of it. Crassus commanded his light-armed soldiers to charge, but they had not gone far before they were received with such a shower of arrows that they were glad to retire amongst the heavy-armed, with whom this was the first occasion of disorder and terror, when they perceived the strength and force of their darts, which pierced their arms, and passed through every kind of covering, hard and soft alike. The Parthians now placing themselves at distances began to shoot from all sides, not aiming at any particular mark (for, indeed, the order of the Romans was so close, that they could not miss if they would), but simply sent their arrows with great force out of strong bent bows, the strokes from which came with extreme violence. The position of the Romans was a very bad one from the first; for if they kept their ranks, they were wounded, and if they tried to charge, they hurt the enemy none the more, and themselves suffered none the less. For the Parthians threw their darts as they fled, an art in which none but the Scythians excel them, and it is, indeed, a cunning practice, for while they thus fight to make their escape, they avoid the dishonour of a flight.
