But Alexander, unlike Buonaparte, was never discouraged by apparent failures. His exertions to repair the causeway and construct fresh machines quite astonished the enemy. As every general should be during great operations, Alexander was present and superintended every part of the works. The dyke was nearly completed, when an impetuous wind drove the waves with such fury against it, that the cement and all gave way, and the water, rushing between the stones, broke it in the middle. As soon as the great heap of stones which supported the earth was thrown down, the whole sunk at once as into an abyss. Even Alexander for a moment debated whether he should abandon his enterprise or not; but his indomitable genius prevailed, and the soldiers began a new mole with as much alacrity as if they had but that moment arrived before the city. Alexander became aware that he could neither complete the causeway nor take the city whilst the Tyrians were masters at sea. He therefore assembled all his galleys before Sidon. The fame of his victory at Issus brought him a considerable accession of naval force; several Asiatic monarchs hastening to pay their court to the conqueror, by supplying him with that of which he stood most in need. The king, whilst his soldiers were preparing the ships and engines, took some troops of horse and his own regiment of guards, and marched towards a mountain of Arabia, called Antilibanus. His affection for his old tutor Lysimachus, who followed him in this expedition, exposed him to one of those dangers which we often find great men, as well as heroes of romance, running into. Lysimachus was evidently a courtier as well as an able tutor, for he knew his pupil’s weak point, and called him Achilles and himself Phœnix. When the king arrived at the foot of the mountain, he leaped from his horse and began to walk. His troops got a considerable distance in advance of him. It became late, but Alexander would not leave his tutor, who was corpulent and short of breath, and was soon, with the exception of a few soldiers, separated from his little army. He was compelled to spend the whole night in this unguarded state very near to a numerous body of the enemy. His good fortune, however, prevailed,--he passed the night in safety, and coming up with his troops in the morning, he advanced into the country, took all the strong places, either by force or capitulation, and, on the eleventh day returned to Sidon, where he found a welcome reinforcement of four thousand Greeks from Peloponnesus.
