On the first day his army constructed the mound the length of a stade; and on the following day the slingers shooting at the Indians from the part already finished, assisted by the missiles which were hurled from the military engines, repulsed the sallies which they made against the men who were constructing the mound. He went on with the work for three days without intermission, and on the fourth day a few of the Macedonians forcing their way occupied a small eminence which was on a level with the rock. Without taking any rest, Alexander went on with the mound, being desirous of connecting his artificial rampart with the eminence which the few men were now occupying for him. But then the Indians, being alarmed at the indescribable audacity of the Macedonians, who had forced their way to the eminence, and seeing that the mound was already united with it, desisted from attempting any longer to resist. They sent their herald to Alexander, saying that they were willing to surrender the rock, if he would grant them a truce. But they had formed the design of wasting the day by continually delaying the ratification of the truce, and of scattering themselves in the night with the view of escaping one by one to their own abodes. When Alexander discovered this plan of theirs, he allowed them time to commence their retreat, and to remove the guard which was placed all round the place. He remained quiet until they began their retreat; then taking 700 of the body-guards and shield-bearing infantry, he was the first to scale the rock at the part of it abandoned by the enemy; and the Macedonians ascended after him, one in one place another in another, drawing each other up. These men at the concerted signal turned themselves upon the retreating barbarians, and killed many of them in their flight. Others retreating with panic terror perished by leaping down the precipices; and thus the rock which had been inexpugnable to Heracles was occupied by Alexander. He offered sacrifice upon it, and arranged a fort, committing the superintendence of the garrison to Sisicottus, who long before had deserted from the Indians to Bessus in Bactra, and after Alexander had acquired possession of the country of Bactra, entered his army and appeared to be eminently trustworthy.
