Alexander marched from the battle-field to Ilion, and advanced thence southward through the beautiful regions of Ionia and the other maritime states, which, in striking contrast to their present blighted condition, were then at the height of prosperity—adorned with numerous rich and splendid cities, which vied with each other in all the arts of refinement. The terror of his name preceded him, and these cities one after another, including even Sardis, the western capital, which was strongly fortified, threw open their gates to admit him. Milêtos, however, and Halikarnassos, being supported by the Persian fleet, refused to surrender, and did not fall into his hands until each had been for some time besieged. After the fall of Halikarnassos, the rest of Karia, of which it was the capital, submitted, and then the operations of the first year of the war were brought to a close by the reduction of all Lykia. In this province he gave his army some rest. The next campaign opened with the conquest of Pamphylia, after which Alexander turned his march away from the coast with a view to invade Phrygia, which lay to the north beyond the lofty range of Tauros. It was now the depth of winter, but Alexander in defiance of all obstacles—frost and snow, torrents and precipices, and the resistance of the fierce Pisidian mountaineers—forced his way into the Phrygian plains. This passage of the Tauros at such a season was an achievement not unworthy to rank with the more celebrated passage of the Alps made by Hannibal about a century later. After he had cleared the defiles, a march of five days brought him to Kelainai, the capital of the greater Phrygia, which was pleasantly situated where the river Marsyas joins the Maeander, and was embellished with a palace and a royal park. Alexander, deeming its acropolis to be impregnable, made terms with the inhabitants, and then advanced to the ancient capital called Gordion, after Gordios, the father of the celebrated Midas, the first king of the country. Here was the complicated knot to which the prophecy was attached that whoever untied it should be Lord of Asia. It was tied on a rope of bark which fastened the yoke to the pole of the wagon on which Midas had been carried into the city on the day when the people chose him as their king. Alexander either undid the knot or cut it through with his sword.
