As it was, the fleet of Persia, composed mainly of Phoenician vessels, did not appear in the northern Egean waters until some weeks after Alexander had transported his grand army into Asia, and fought at the Granicus, so that when it arrived it was of comparatively little service. Too late even to save Miletus, it had to be a tame spectator of the siege and capture of that important town.[14356] It was then withdrawn to Halicarnassus, where its presence greatly helped the defence, but not to the extent of wholly baffling the besiegers. Halicarnassus fell, like Miletus, after a while, being entered from the land side; but the fleet saved the troops, the stores, and the inhabitants.[14357] During the early part of the ensuing year, B.C. 333, while Alexander was engaged in conquering the interior of Asia Minor, the Persian fleet under Memnon at last took the aggressive, and, advancing northwards, employed itself in establishing Persian influence over the whole of the Egean, and especially in reducing the important islands of Chios and Lesbos.[14358] Memnon was now in full command. Fortune smiled on him; and it seemed more than probable that the war would be, at least partially, transferred into Greece, where the Spartans only waited for Memnon’s appearance to commence an anti-Macedonian movement. The presence of a powerful fleet in Greek waters, and Memnon’s almost unlimited command of Persian gold, might in a short time have raised such a flame in Greece as to necessitate Alexander’s return in order to extinguish it.[14359] The invasion of Asia might have been arrested in mid course; Alexander might have proved as powerless as Agesilaus to effect any great change in the relations of the two continents; but, at the critical moment, the sudden and unexpected death of the Rhodian chief cast all these hopes to the ground,[14360] and deprived Persia of her last chance of baffling the invader.
