Crassus

And when Crassus ordered his light-armed troops to make a charge, they did not advance far, but encountering a multitude of arrows, abandoned their undertaking and ran back for shelter among the men-at-arms, among whom they caused the beginning of disorder and fear, for these now saw the velocity and force of the arrows, which fractured armour, and tore their way through every covering alike, whether hard or soft.

But the Parthians now stood at long intervals from one another and began to shoot their arrows from all sides at once, not with any accurate aim (for the demise formation of the Romans would not suffer an archer to miss his man even if he wished it), but making vigorous and powerful shots from bows which were large and mighty and curved so as to discharge their missiles with great force.

At once, then, the plight of the Romans was a grievous one; for if they kept their ranks, they were wounded in great numbers, and if they tried to come to close quarters with the enemy, they were just as far from effecting anything and suffered just as much. For the Parthians shot as they fled, and next to the Scythians, they do this most effectively; and it is a very clever thing to seek safety while still fighting, and to take away the shame of flight.

Now as long as they had hopes that the enemy would exhaust their missiles and desist from battle or fight at close quarters, the Romans held out; but when they perceived that many camels laden with arrows were at hand, from which the Parthians who first encircled them took a fresh supply, then Crassus, seeing no end to this, began to lose heart, and sent messengers to his son with orders to force an engagement with the enemy before he was surrounded; for it was his wing especially which the enemy were attacking and surrounding with their cavalry, in the hope of getting in his rear.

Accordingly, the young wan took thirteen hundred horsemen, of whom a thousand had come from Caesar, five hundred archers, and eight cohorts of the men-at-arms who were nearest him, and led them all to the charge. But the Parthians who were trying to envelop him, either because, as some say, they encountered marshes, or because they were maneuvering to attack Publius as far as possible from his father, wheeled about and made off.

Then Publius, shouting that the men did not stand their ground, rode after them, and with him Censorinus and Megabacchus, the latter distinguished for his courage and strength, Censorinus a man of senatorial dignity and a powerful speaker, and both of them comrades of Publius and nearly of the same age. The cavalry followed after Publius, and even the infantry kept pace with them in the zeal and joy which their hopes inspired; for they thought they were victorious and in pursuit of the enemy, until, after they had gone forward a long distance, they perceived the ruse. For the seeming fugitives wheeled about and were joined at the same time by others more numerous still.
