Alexander had sent envoys before him to summon a fresh congress at Corinth. He found this assembly as obsequious as that which had been called by his father; and was invested by it with the same title and authority for the prosecution of the war with Persia, as had been bestowed on Philip. Sparta alone either refused to send deputies to the congress, or instructed them to disavow its proceedings. She had been used—such was still her language—herself to take the lead among the Greeks, and would not resign her hereditary rank to another. Alexander perhaps smiled at these pretensions of a state which was hardly able to protect itself, but did not think it worth while to put its resolution to the test, by an invasion of its territory. So too the revolt of Ambracia did not appear to him important enough to detain him so long as would have been necessary to crush it. He even condescended to assure the Ambracians that they had only forestalled his intentions: that he should of his own accord have restored their democratical institutions. It was a concession which his commanding posture enabled him to make with dignity, and therefore without danger. Having thus in the course of a few weeks settled the affairs of Greece, he returned to Macedonia, with the hope that in the following spring he might be able to embark for Asia.
ALEXANDER WINNOWS THE NORTH
But when the season for military operations drew near in 335, reports were heard of movements among the Thracian tribes and the Triballians, which seemed to render it necessary, for the security of his kingdom during his absence, that he should spread the terror of his arms in that quarter, before he began an expedition which would carry him so far away from it. Early in the spring Alexander set out on his march toward the Danube. A small squadron of ships of war was ordered to be fitted out at Byzantium, and to sail up the river to meet the army. In ten days, having crossed the Hebrus at Philippopolis, it reached the foot of the Balkan. Here the Thracians had collected their forces to guard the defiles, and were seen entrenched behind their wagons on the summit of the pass. As the road which led up to it was extremely steep, they had formed the plan of rolling their wagons down on the enemy as they advanced, and then falling on their broken ranks. Alexander perceived the object of their preparations, and provided against the danger. The heavy infantry were ordered, where the ground permitted, to open their files and make way for the wagons: where this was not practicable, to throw themselves forward on the ground, and link their shields together over their heads, so that the descending masses might bound over them. The shock came and passed in a few moments, leaving the men unhurt; they closed their ranks, and rose from the ground with heightened courage. The enemy were soon dislodged from their position by a skilful and vigorous charge, leaving fifteen hundred slain: the fugitives easily escaped; the camp, in which were their wives and children, fell into the hands of the victors.
Having crossed the mountains without further interruption, Alexander now resumed his march, and in three days reached the right bank of the Danube, where he found the galleys which he expected from Byzantium. Under favour of night they crossed over unmolested, and landed in fields of standing corn. This the phalanx levelled, as it marched through, with its spears, the cavalry following until they reached the open ground, where the enemy, astonished and dismayed by their unexpected appearance, did not even wait for the first charge of the horse, but took refuge in their town which lay but a few miles off. Even this—for it was poorly fortified—they abandoned at Alexander’s approach, and taking as many as they could of the women and children on their horses, retreated into the wilderness. The town was sacked and razed to the ground, and Alexander having sacrificed on the right bank of the Danube to the gods who had granted him a safe passage, returned to his camp on the other side. Here he received embassies, with submissive or at least pacific overtures, from Syrmus, and from many of the independent nations bordering on the river. His chief object was attained in the proof thus afforded of the terror inspired by his arms.
