Many were persuading Lucullus to defer the war, but he rejected their counsel, and marched through Bithynia and Galatia into the king's country, in such great scarcity of provision at first, that thirty thousand Galatians followed, every man carrying a bushel of wheat at his back. But subduing all in his progress before him, he at last found himself in such great plenty that an ox was sold in the camp for a single drachma, and a slave for four. The other booty they made no account of, but left it behind or destroyed it; there being no disposing of it, where all had such abundance. But when they had made frequent incursions with their cavalry, and had advanced as far as Themiscyra, and the plains of the Thermodon, merely laying waste the country before them, they began to find fault with Lucullus, asking "why he took so many towns by surrender, and never one by storm, which might enrich them with the plunder? and now, forsooth, leaving Amisus behind, a rich and wealthy city, of easy conquest, if closely besieged, he will carry us into the Tibarenian and Chaldean wilderness, to fight with Mithridates." Lucullus, little thinking this would be of such dangerous consequence as it afterwards proved, took no notice and slighted it; and was rather anxious to excuse himself to those who blamed his tardiness, in losing time about small, pitiful places not worth the while, and allowing Mithridates opportunity to recruit. "That is what I design," said he, "and sit here contriving by my delay, that he may grow great again, and gather a considerable army, which may induce him to stand, and not fly away before us. For do you not see the wide and unknown wilderness behind? Caucasus is not far off, and a multitude of vast mountains, enough to conceal ten thousand kings that wished to avoid a battle. Besides this, a journey but of few days leads from Cabira to Armenia, where Tigranes reigns, king of kings, and holds in his hands a power that has enabled him to keep the Parthians in narrow bounds, to remove Greek cities bodily into Media, to conquer Syria and Palestine, to put to death the kings of the royal line of Seleucus, and carry away their wives and daughters by violence. This same is relation and son-in-law to Mithridates, and cannot but receive him upon entreaty, and enter into war with us to defend him; so that, while we endeavour to dispose Mithridates, we shall endanger the bringing in of Tigranes against us, who already has sought occasion to fall out with us, but can never find one so justifiable as the succour of a friend and prince in his necessity. Why, therefore, should we put Mithridates upon this resource, who as yet does not see how he may best fight with us, and disdains to stoop to Tigranes; and not rather allow him time to gather a new army and grow confident again, that we may thus fight with Colchians and Tibarenians whom we have often defeated already, and not with Medes and Armenians."Upon these motives, Lucullus sat down before Amisus, and slowly carried on the siege. But the winter being well spent, he left Murena in charge of it, and went himself against Mithridates, then rendezvousing at Cabira, and resolving to await the Romans, with forty thousand foot about him and fourteen thousand horse, on whom he chiefly confided. Passing the river Lycus, he challenged the Romans into the plains, where the cavalry engaged, and the Romans were beaten. Pomponius, a man of some note, was taken wounded; and sore, and in pain as he was, was carried before Mithridates, and asked by the king if he would become his friend if he saved his life. He answered, "Yes, if you become reconciled to the Romans; if not, your enemy." Mithridates wondered at him, and did him no hurt. The enemy being with their cavalry master of the plains, Lucullus was something afraid, and hesitated to enter the mountains, being very large, woody, and almost inaccessible, when by good-luck, some Greeks who had fled into a cave were taken, the eldest of whom, Artemidorus by name, promised to bring Lucullus, and seat him in a place of safety for his army, where there was a fort that overlooked Cabira. Lucullus, believing him, lighted his fires, and marched in the night; and safely passing the defile, gained the place, and in the morning was seen above the enemy, pitching his camp in a place advantageous to descend upon them if he desired to fight, and secure from being forced if he preferred to lie still. Neither side was willing to engage at present. But it is related that some of the king's party were hunting a stag, and some Romans wanting to cut them off, came out and met them. Whereupon they skirmished, more still drawing together to each side, and at last the king's party prevailed, on which the Romans, from their camp seeing their companions fly, were enraged, and ran to Lucullus with entreaties to lead them out, demanding that the sign might be given for battle. But he, that they might know of what consequence the presence and appearance of a wise commander is in time of conflict and danger, ordered them to stand still. But he went down himself into the plains, and meeting with the foremost that fled, commanded them to stand and turn back with him. These obeying, the rest also turned and formed again in a body, and thus, with no great difficulty, drove back the enemies, and pursued them to their camp. After his return, Lucullus inflicted the customary punishment upon the fugitives, and made them dig a trench of twelve foot, working in their frocks unfastened, while the rest stood by and looked on.
