As the reader will have learned long before this time, it was not the nature of Pyrrhus to remain on the spot and grapple with difficulties like these. If there were any new enterprise to be undertaken, or any desperate battle to be fought on a sudden emergency, Pyrrhus was always ready and eager for action, and almost sure of success. But he had no qualities whatever to fit him for the exigencies of such a crisis as this. He had ardor and impetuosity, but no perseverance or decision. He could fight, but he could not plan. He was recklessly and desperately brave in encountering physical danger, but, when involved in difficulties and embarrassments, his only resource was to fly. Accordingly, it was soon announced in Sicily that Pyrrhus had determined to postpone his plan of proceeding to Africa, and was going back to Tarentum, whence he came. He had received intelligence from Tarentum, he said, that required his immediate return to that city. This was probably true; for he had left things in such a condition at Tarentum, that he was, doubtless, continually receiving such intelligence from that quarter. Whether he received any special or extraordinary summons from Tarentum just at this time is extremely uncertain. He, however, pretended that such a message had come; and under this pretense he sheltered himself in his intended departure, so as just to escape the imputation of being actually driven away.
His enemies, however, did not intend to allow him to depart in peace. The Carthaginians, being apprised of his design, sent a fleet to watch the coast and intercept him; while the Mamertines, crossing the Strait, marched to the place on the coast of Italy where they expected he would land, intending to attack him as soon as he should set foot upon the shore. Both these plans were successful. The Carthaginians attacked his fleet, and destroyed many of his ships. Pyrrhus himself barely succeeded in making his escape with a small number of vessels, and reaching the shore. Here, as soon as he gained the land, he was confronted by the Mamertines, who had reached the place before him with ten thousand men. Pyrrhus soon collected from the ships that reached the land a force so formidable that the Mamertines did not dare to attack him in a body, but they blocked up the passes through which the way to Tarentum lay, and endeavored in every way to intercept and harass him in his march. They killed two of his elephants, and cut off many separate detachments of men, and finally deranged all his plans, and threw his whole army into confusion. Pyrrhus at length determined to force his enemies to battle. Accordingly, as soon as a favorable opportunity occurred, he pushed forward at the head of a strong force, and attacked the Mamertines in a sudden and most impetuous manner.
