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.
