Before deciding to comply with the request of the Tarentines that he would come to their aid, Alexander sent to a celebrated oracle in Epirus, called the oracle of Dodona, to inquire whether it would be safe for him to undertake the expedition. To his inquiries the oracle gave him this for an answer: "The waters of Acheron will be the cause of your death, and Pandosia is the place where you will die." Alexander was greatly rejoiced at receiving this answer. Acheron was a stream of Epirus, and Pandosia was a town upon the banks of it. He understood the response to mean that he was fated to die quietly in his own country at some future period, probably a remote one, and that there was no danger in his undertaking the expedition to which he had been called. He accordingly set sail from Epirus, and landed in Italy; and there, believing that he was fated to die in Epirus, and not in Italy, he fought in every battle with the most desperate and reckless bravery, and achieved prodigies of valor. The possibility that there might be an Acheron and a Pandosia in Italy, as well as in Epirus, did not occur to his mind. For a time he was very successful in his career. He fought battles, gained victories, conquered cities, and established his dominion over quite an extended region. In order to hold what he had gained, he sent over a great number of hostages to Epirus, to be kept there as security for the continued submission of those whom he had subdued. These hostages consisted chiefly, as was usual in such cases, of children. At length, in the course of the war, an occasion arose in which it was necessary, for the protection of his troops, to encamp them on three hills which were situated very near to each other. These hills were separated by low interval lands and a small stream; but at the time when Alexander established his encampment, the stream constituted no impediment to free intercommunication between the different divisions of his army. There came on, however, a powerful rain; the stream overflowed its banks; the intervals were inundated. This enabled the enemy to attack two of Alexander's encampments, while it was utterly impossible for Alexander himself to render them any aid. The enemy made the attack, and were successful in it. The two camps were broken up, and the troops stationed in them were put to flight. Those that remained with Alexander, becoming discouraged by the hopeless condition in which they found themselves placed, mutinied, and sent to the camp of the enemy, offering to deliver up Alexander to them, dead or alive, as they should choose, on condition that they themselves might be allowed to return to their native land in peace. This proposal was accepted; but, before it was put in execution, Alexander, having discovered the plot, placed himself at the head of a determined and desperate band of followers, broke through the ranks of the enemies that surrounded him, and made his escape to a neighboring wood.
