So they perished, pushed about and trampled down by one another without being able to defend themselves or venture any movement against the enemy. For whereas they were strongest in cavalry and bowmen, they were unable to see before them in the darkness and unable to make any manoeuvre in the defile. When the moon rose, some rejoiced, with the idea that in the light they could certainly ward off some one. And they would have been benefited a little, if the Romans had not had the moon behind them, and so produced much illusion both in sight and in action, while assailing them now on this side and now on that. For the attackers, being many in number and all in one body, casting the deepest imaginable shadow, baffled their opponents before they had yet come into conflict with them. The barbarians thinking them near would strike the empty air in vain and when they reached common ground would be wounded in the shadow where they were not expecting it. Thus numbers of them were killed and the captives were not fewer than the slain. Many also escaped, among them Mithridates. [-50-] The latter's next move was to hasten to Tigranes. On sending couriers to him, however, he found no friendship awaiting him, because Tigranes' son had risen against him, and while holding the youth under guard[9] the father suspected that Mithridates, his grandfather, had been responsible for the quarrel. For this reason far from receiving him Tigranes even arrested and threw into prison the men sent ahead by him. Failing therefore of the hoped-for refuge he turned aside into Colchis, and thence on foot reached Maeotis and the Bosphorus, using persuasion with some and force with others. He recovered the territory, too, having terrified Machares, his son, who had espoused the cause of the Romans and was then ruling it, to such an extent that he would not even come into his presence. And him Mithridates caused to be killed through his associates to whom he promised to grant immunity and money. In the course of these events Pompey sent men to pursue him: when, however, he outstripped them by fleeing across the Phasis, the Roman leader colonized a city in the territory where he had been victorious, bestowing it upon the wounded and the more elderly of his soldiers. Many of those living round about voluntarily joined the settlement and later generations of them are in existence even now, being called Nicopolitans [10] and paying tribute to the province of Cappadocia.
