the flanks of Lebanon, intercept his supplies, cut off his foragers, and make his position untenable; the Tyrians could scarcely anticipate that Persia would sit with folded hands, a calm spectator of a seven months’ siege, and do absolutely nothing. Having determined on resistance to the demands of Alexander, the Tyrians lost no time in placing their city in a position to resist attack. They summoned their king, Azemilcus, from the Persian fleet, and required him to hasten home with the entire squadron which he commanded.[14374] They collected triremes and lighter vessels from various quarters. They distributed along the walls of the city upon every side a number of engines of war, constructed to hurl darts and stones, and amply provided them with missiles.[14375] The skilled workmen and engineers resident in the town were called upon not merely to furnish additional engines of the old type, but to exercise their ingenuity in devising new and unheard of structures.[14376] They armed all the young and vigorous among the people, and appointed them their several stations at the walls. Finally, to diminish the number of mouths to be fed, and to save themselves from distracting cares, they sent away to Carthage a number of their aged men, their women, and their children, who were readily received and supported by the rich and friendly colonists.[14377] Meantime Alexander had taken his resolution. Either recollecting what Xerxes had threatened to do at Salamis, or prompted merely by his own inventive genius, he determined on the construction of a great mole, or embankment, which should be carried out from the Asiatic mainland across the half-mile of channel to the very walls of the recalcitrant city, and should thus join the island to the Syrian shore. The width of the embankment he fixed at two plethra, or nearly seventy yards.[14378] Material for the construction was abundant. The great city of Palæ-Tyrus was close at hand, partly in ruins, and with many of the houses deserted by their inhabitants. Its walls would furnish abundance of stone, mortar, and rubble. Behind Palæ-Tyrus lay the flanks of Lebanon, cultivated in orchards, while beyond were its dense and inexhaustible forests of fir, pine, and cedar. Human labour could be obtained to almost any extent, for the neighbourhood was populous, and Alexander’s authority acknowledged by all. Accordingly the work, once commenced, for a while made fair progress. Piles were cut in the mountain, which were driven with much ease into the soft mud of the channel, which was shallow near the shore,[14379] and completely under the control of the Macedonians, since the Tyrian vessels could not approach it for fear of sticking in the ooze. Between the piles, towards the edge of the mole, were sunk stones, trunks of trees, and material of the more solid character, while the central part was filled up with rubble and rubbish of every sort and kind. Still, the operation was toilsome and tedious,
