Alexander indignantly dismissed their ambassadors, and called a council of his officers, in which he declared his intention of besieging Tyre, and explained the reasons which rendered this undertaking necessary, arduous as it was. He observed that it would be unsafe to invade Egypt, so long as the Persians commanded the sea, and that to advance into the interior against Darius, while Tyre remained neutral or vacillating, and while Cyprus and Egypt were in the enemy’s hands, would be to let the war be transferred to Greece, where Sparta was openly hostile, and Athens only withheld from the avowal of her enmity by fear. On the other hand the reduction of Tyre would be attended with the submission of all Phœnicia; and the Phœnician fleet, the strength of the Persian navy, would soon pass over to the power which possessed the cities by which it had been equipped, and to which the crews belonged. Cyprus would then speedily fall, and there would be no further obstacle to the conquest of Egypt. They might then set out for Babylon, leaving all secure on the side of Greece, and with the proud consciousness that they had already severed all the provinces west of the Euphrates from the Persian empire.

The motives which induced Alexander to undertake the siege of Tyre are more evident than those which led the Tyrians to defy his power, after so many of the other Phœnician cities had submitted to him. The main ground of their conduct seems to have been more in the nature of a commercial calculation of expediency. The issue of the contest between Alexander and Darius was still doubtful; notwithstanding his past success the Macedonian conqueror might meet the fate of the younger Cyrus in some future field of battle. In any case the Tyrians believed their city to be impregnable so long as they were superior at sea. It was thought necessary, either for the purpose of detaining the god, or of quieting the popular uneasiness, to adopt an expedient similar to that which many years before had been employed by the Ephesians in a like emergency—to fasten the statue of Apollo, who was denounced as a friend of Alexander, by a golden chain to the altar of Melkarth. On the other hand Alexander seems to have thought it prudent to raise the spirits of his troops by assurances of divine assistance, in an enterprise which appeared to surpass human ability. He too related that he had seen Hercules in a dream taking him by the hand, and leading him within the walls of his city—a sign, as Aristander interpreted it, of success, though in a Herculean labour.

An ordinary conqueror might indeed himself have needed such assurances to encourage him, when he was about to attack a place so prepared for defence as Tyre at this time was, both by nature and art. The island on which the city stood was separated from the main by a channel half a mile broad, through which, in rough weather, the sea rushed with great violence. This strait was indeed shallow on the side of the Phœnician coast, but near the island became three fathoms deep. The walls, which rose from the edge of the cliffs, were 150 feet high on the land side, and composed of huge blocks of stone, cemented with mortar. The city was abundantly stocked with provisions and military stores, contained a number of copious springs; was filled with an industrious and intelligent population, expert in all the arts of naval warfare, and possessed mechanics and engineers, not inferior, it seems, to any that were to be found in the Macedonian camp. Though the greater part of the Tyrian fleet was absent in the Persian service, there still remained a sufficient number of galleys of war, and of smaller craft, both for the defence of the harbours—for there were two, one on the north, the other on the south side of the island—and for the annoyance of the enemy.

Alexander had no naval force which he could immediately oppose to this. His plan was soon formed: he resolved to carry a causeway through the channel, and when it had reached the foot of the walls, to batter them from it with his engines. The real difficulty of the undertaking was not perceived until the dam had been carried halfway across the water. But as the depth increased, while the work itself became more and more laborious and difficult, it now came within reach of the missiles discharged from the top of the walls; and the Tyrian galleys, taking their station at a short distance, incessantly annoyed the workmen, who were not armed to sustain these attacks. Alexander however ordered two wooden towers erected both to shelter the workmen and repel the assailants.

The Tyrians now prepared a more formidable mode of attack. A horse transport was filled with dry twigs and other combustibles, over which they poured pitch and brimstone. In the forepart an additional space was enclosed, so as to form a huge basket for the reception of these materials, in the midst of which were fixed two masts, which at the ends of their yard-arms supported two cauldrons filled with an inflammable liquid. The stem was raised high above the water by means of ballast heaped near the stern. The besieged, having waited for a favourable breeze, towed the ship behind two galleys towards the mole, and when it came near set it on fire, and, seconded by the wind, ran it on the end of the mole between the towers. The flames soon caught them; but the conflagration did not reach its full height, until the masts gave way and discharged the contents of the cauldrons on the blazing pile. To render it the more effectual, the men on board the galleys from a convenient distance plied the towers with their arrows, so as to defeat every attempt that was made to extinguish the fire.

A shoal of boats now came off from the harbours filled with people, who soon tore up the piles, and set fire to all the machines which had not been overtaken by the flames of the burning ship. The ruin of the work which had cost so much time and labour was completed in a few hours. Alexander, however, was not disheartened; he gave orders that a new mole should be begun, of greater breadth, so as to be capable of receiving more towers, and that new engines should be constructed. But as he now became aware that, without some naval force to oppose to the Tyrians, he should find the difficulties of the siege insurmountable, he repaired at once in person to Sidon, with a detachment of light troops, to collect as many galleys as he could.

Gerostratus, king of Aradus, and Enylus of Byblus, as soon as they heard that he had become master of their cities, quitted the Persian fleet, with their squadrons, and with a part of the Sidonian galleys; so that Alexander was joined at Sidon by eighty sail of Phœnician ships. About the same time came in ten from Rhodes, as many from Lycia, three from Soli and Mallus, and his own victorious captain, Proteas, from Macedonia. And these were followed not long after by the Cypriote princes with 120 galleys. He had now an armament of nearly 250 sail at his orders. While it went through a course of training for a sea-fight, and while the machines were in preparation, he made an excursion, with some squadrons of horse and a body of light troops, into the range of Anti-Libanus, and having reduced the mountaineers to submission, within eleven days returned to Sidon, where he found a reinforcement of four thousand Greek soldiers, who had been brought by Cleander from Peloponnesus. He then set sail for Tyre in line of battle, himself, as on shore, commanding the right wing, and Craterus the left. The Tyrians, it seems, expected his approach and were prepared to meet him; when they saw the numbers which he brought with him, they gave up all thoughts of resistance, and only used their galleys to block up the mouths of their harbours. Alexander, when he came up, found the northern harbour too well secured to be attacked, though he sank three of the enemy’s galleys which were moored on the outside, and captured one which was consecrated to the tutelary god. The next day he stationed the Cypriotes under the command of Andromachus near the entrance of this harbour, and the Phœnicians near the other, in the same quarter where his own tent was pitched.

In the meanwhile the mole had been restored, and was actively carried forward; mechanics had been collected in great numbers from Phœnicia and Cyprus, and had constructed abundance of engines, which were planted, some on the mole, others on transports and on the heavier galleys. These vessels at first found the approach very much impeded by a bed of stones which the besieged had carried out into the sea from the foot of the cliffs; and the attempts which the Macedonians made to remove this obstacle were for some time thwarted by the dexterity and boldness of the Tyrian divers, who cut the cables of the ships which were anchored for the purpose of drawing up the stones. Chain cables were at length substituted, and the passage was then rapidly cleared by machines, which raised the stones out of their bed, and hurled them into the deep water. The walls were now assailed by the engines on every side, and the contest grew closer and hotter than it had ever been. Every contrivance that ingenuity quickened by fear could suggest was tried by the besieged to ward off these attacks.
