While he was there, ambassadors came to him from the Selgians, who are also Pisidian barbarians, inhabiting a large city, and being warlike. Because they happened to be inveterate enemies to the Termessians they had despatched this embassy to Alexander, to treat for his friendship. He made a treaty with them, and from this time found them faithful allies in all his proceedings. Despairing of being able to capture Termessus without a great loss of time, he marched on to Sagalassus. This was also a large city, inhabited likewise by Pisidians; and though all the Pisidians are warlike, the men of this city were deemed the most so. On this occasion they had occupied the hill in front of the city, because it was no less strong than the walls, from which to attack the enemy; and there they were awaiting him. But Alexander drew up the phalanx of Macedonians in the following way: on the right wing, where he had himself taken up his position, he held the shield-bearing guards, and next to these he extended the foot Companions as far as the left wing, in the order that each of the generals had precedence in the array that day. On the left wing he stationed Amyntas, son of Arrhabaeus, as commander. In front of the right wing were posted the archers and Agrianians, and in front of the left wing the Thracian javelin-throwers under the command of Sitalces. But the cavalry were no use to him in a place so rough and unfavourable. The Termessians also had come to the aid of the Pisidians, and arrayed themselves with them. Alexander had already made an attack upon the mountain which the Pisidians were occupying, advancing up the most abrupt part of the ascent, when the barbarians from an ambuscade attacked him on both wings, in a place where it was very easy for themselves to advance, but where the route was very difficult for their enemy. The archers, who were the first to approach, were put to rout, inasmuch as they were insufficiently armed; but the Agrianians stood their ground, for the Macedonian phalanx was already drawing near, at the head of which Alexander himself was seen. When the battle became a hand-to-hand one, though the barbarians were destitute of armour, they rushed against the Macedonian hoplites, and fell wounded on all sides. Then, indeed, they gave way, after about 500 of them had been killed. As they were nimble and well-acquainted with the locality, they effected their retreat without difficulty; whereas the Macedonians, on account of the heaviness of their arms and their ignorance of the roads, durst not pursue them vigorously. Alexander therefore held off from the fugitives, and took their city by storm. Of those with him, Cleander, the general of the archers, and about twenty others were slain. Alexander then marched against the rest of the Pisidians, and took some of their strongholds by storm; others he won over to him by granting them terms of capitulation. CHAPTER XXIX.
