rode away; not but that Crassus was aware of his going, but he had persuaded him that he would go and contrive how to disorder the affairs of the enemy.
It is related that Crassus came abroad that day not in his scarlet robe, which Roman generals usually wear, but in a black one, which, as soon as he perceived, he changed. And the standard-bearers had much ado to take up their eagles, which seemed to be fixed to the place. 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 drought 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 armor 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 clamor. 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.
