How far there was any truth in the charge which Demetrius brought against Alexander of intending to kill him, it is, of course, impossible to say. There was no evidence of the fact, nor could there be any evidence but such as Demetrius might easily fabricate. It is the universal justification that is offered in every age by the perpetrators of political crimes, that they were compelled to perform themselves the deeds of violence and cruelty for which they are condemned, in order to anticipate and preclude the performance of similar deeds on the part of their enemies.

Relations between Demetrius and Pyrrhus.

Demetrius and Pyrrhus were now neighboring kings, and, from the friendly relations which had subsisted between them for so many years, it might, perhaps, be supposed that the two kingdoms which they respectively ruled would enjoy, from this time, a permanent and settled peace, and maintain the most amicable intercourse with each other. But the reverse was the fact. Contentions and quarrels arose on the frontiers. Each nation complained that the borderers of the other made inroads over the frontier. Demetrius and Pyrrhus gradually got drawn into these disputes. Unfortunately for the peace of the two countries, Deidamia died, and the strong band of union which she had formed between the two reigning families was sundered. In a word, it was not long before Pyrrhus and Demetrius came to open war.

War breaks out between them.
Thebes.

The war, however, which thus broke out between Demetrius and Pyrrhus did not arise wholly from accidental collisions occurring on the frontiers. Demetrius was a man of the most violent and insatiable ambition, and wholly unscrupulous in respect to the means of gratifying the passion. Before his difficulties with Pyrrhus began, he had made expeditions southwardly into Greece, and had finally succeeded in reducing a large portion of that country to his sway. He, however, at one time, in the course of his campaigns in Greece, narrowly escaped a very sudden termination of his career. He was besieging Thebes, one of the principal cities of Greece, and one which was obstinately determined not to submit to him. In fact, the inhabitants of the city had given him some special cause of offense, so that he was excessively angry with them, and though for a long time he made very little progress in prosecuting the siege, he was determined not to give up the attempt. At one period, he was himself called away from the place for a time, to engage in some military duty demanding his attention in Thessaly, and during his absence he left his son to conduct the siege. On his return to Thebes, he found that, through the energetic and obstinate resistance which was made by the people of Thebes, great numbers of his men were continually falling—so much so, that his son began to remonstrate with him against allowing so great and so useless a slaughter to go on. "Consider," said he, "why you should expose so many of your valiant soldiers to such sure destruction, when—"

Here Demetrius, in a passion, interrupted him, saying, "Give yourself no concern about how many of the soldiers are killed. The more there are killed, the fewer you will have to provide subsistence for!"

Recklessness and cruelty of Demetrius.

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.

War between Pyrrhus and Demetrius.

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.
