These letters so far moved Seleucus, that he gave orders to the governors of those provinces that they should furnish Demetrius with all things suitable to his royal rank, and with sufficient provisions for his troops. But Patrocles, a person whose judgment was greatly valued, and who was a friend highly trusted by Seleucus, pointed out to him that the expense of maintaining such a body of soldiers was the least important consideration, but that it was contrary to all policy to let Demetrius stay in the country, since he, of all the kings of his time, was the most violent, and most addicted to daring enterprises; and he was now in a condition which might tempt persons of the greatest temper and moderation to unlawful and desperate attempts. Seleucus, excited by this advice, moved with a powerful army towards Cilicia; and Demetrius, astonished at this sudden alteration, betook himself for safety to the most inaccessible places of Mount Taurus; from whence he sent envoys to Seleucus, to request from him that he would permit him the liberty to settle with his army somewhere among the independent barbarian tribes, where he might be able to make himself a petty king, and end his life without further travel and hardship; or, if he refused him this, at any rate to give his troops food during the winter, and not expose him in this distressed and naked condition to the fury of his enemies.
But Seleucus, whose jealousy made him put an ill-construction on all he said, sent him answer, that he would permit him to stay two months and no longer in Cataonia, provided he presently sent him the principal of his friends as hostages for his departure then; and, in the meantime, he fortified all the passages into Syria. So that Demetrius, who saw himself thus, like a wild beast, in the way to be encompassed on all sides in the toils, was driven in desperation to his defence, overran the country, and in several engagements in which Seleucus attacked him, had the advantage of him. Particularly, when he was once assailed by the scythed chariots, he successfully avoided the charge and routed his assailants, and then, expelling the troops that were in guard of the passes, made himself master of the roads leading into Syria. And now, elated himself, and finding his soldiers also animated by these successes, he was resolved to push at all, and to have one deciding blow for the empire with Seleucus;who indeed was in considerable anxiety and distress, being averse to any assistance from Lysimachus, whom he both mistrusted and feared, and shrinking from a battle with Demetrius, whose desperation he knew, and whose fortune he had so often seen suddenly pass from the lowest to the highest.
But Demetrius, in the meanwhile, was taken with a violent sickness, from which he suffered extremely himself, and which ruined all his prospects. His men deserted to the enemy, or dispersed. At last, after forty days, he began to be so far recovered as to be able to rally his remaining forces, and marched as if he directly designed for Cilicia; but in the night, raising his camp without sound of trumpet, he took a countermarch, and, passing the mountain Amanus, he ravaged all the lower country as far as Cyrrhestica.
Upon this, Seleucus advancing towards him and encamping at no great distance, Demetrius set his troops in motion to surprise him by night. And almost to the last moment Seleucus knew nothing, and was lying asleep. Some deserter came with the tidings just so soon that he had time to leap, in great consternation, out of bed, and give the alarm to his men. And as he was putting on his boots to mount his horse, he bade the officers about him look well to it, for they had to meet a furious and terrible wild beast. But Demetrius, by the noise he heard in the camp, finding they had taken the alarm, drew off his troops in haste. With the morning's return he found Seleucus pressing hard upon him; so, sending one of his officers against the other wing, he defeated those that were opposed to himself. But Seleucus, lighting from his horse, pulling off his helmet, and taking a target, advanced to the foremost ranks of the mercenary soldiers, and, showing them who he was, bade them come over and join him, telling them that it was for their sakes only that he had so long forborne coming to extremities. And thereupon, without a blow more, they saluted Seleucus as their king and passed over.
Demetrius, who felt that this was his last change of fortune, and that he had no more vicissitudes to expect, fled to the passes of Amanus, where, with a very few friends and followers, he threw himself into a dense forest, and there waited for the night, purposing, if possible, to make his escape towards Caunus, where he hoped to find his shipping ready to transport him. But upon inquiry, finding that they had not provisions even for that one day, he began to think of some other project. Whilst he was yet in doubt, his friend Sosigenes arrived, who had four hundred pieces of gold about him, and, with this relief, he again entertained hopes of being able to reach the coast, and, as soon as it began to be dark, set forward towards the passes.
But, perceiving by the fires that the enemies had occupied them, he gave up all thought of that road, and retreated to his old station in the wood, but not with all his men; for some had deserted, nor were those that remained as willing as they had been. One of them, in fine, ventured to speak out, and say that Demetrius had better give himself up to Seleucus; which Demetrius overhearing, drew out his sword, and would have passed it through his body, but that some of his friends interposed and prevented the attempt, persuading him to do as had been said. So at last he gave way, and sent to Seleucus, to surrender himself at discretion.
