The brutal recklessness, however, which Demetrius thus evinced in respect to the slaughter of his troops was not attended, as such a feeling often is, with any cowardly unwillingness to expose himself to danger. He mingled personally in the contests that took place about the walls of the city, and hazarded his own life as freely as he required his soldiers to hazard theirs. At length, on one occasion, a javelin thrown from the wall struck him in the neck, and, passing directly through, felled him to the ground. He was taken up for dead, and borne to his tent. It was there found, on examination, that no great artery or other vital part had been wounded, and yet in a very short time a burning fever supervened, and for some time the life of Demetrius was in imminent danger. He still, however, refused to abandon the siege. At length, he recovered from the effects of his wound, and, in the end, the city surrendered. It was on the return of Demetrius to Macedon, after the close of his successful campaign in Greece, that the war between him and Pyrrhus broke out. As soon as it appeared that actual hostilities were inevitable, both parties collected an army and prepared for the conflict. They marched to meet each other, Pyrrhus from Epirus, and Demetrius from Macedon. It happened, however, that they took different routes, and thus passed each other on the frontier. Demetrius entered Epirus, and found the whole country open and defenseless before him, for the military force of the country was all with Pyrrhus, and had passed into Macedon by another way. Demetrius advanced accordingly, as far as he chose, into Pyrrhus's territories, capturing and plundering every thing that came in his way. Pyrrhus himself, on the other hand, met with quite a different reception. Demetrius had not taken all his army with him, but had left a large detachment under the command of a general named Pantauchus, to defend the country during his absence. Pyrrhus encountered Pantauchus as he entered Macedon, and gave him battle. A very hard-fought and obstinate conflict ensued. In the course of it, Pantauchus challenged Pyrrhus to single combat. He was one of the most distinguished of Demetrius's generals, being celebrated above all the officers of the army for his dexterity, strength, and courage; and, as he was a man of very high and ambitious spirit, he was greatly pleased with the opportunity of distinguishing himself that was now before him. He conceived that a personal encounter with so great a commander as Pyrrhus would add very much to his renown.
