to storm the place until his own arrival, so that no one might escape and carry the news of Alexander’s approach to the other barbarians. He then made an assault upon the wall, which the barbarians abandoned on seeing it could no longer hold out, since many had been killed during the siege, and others disabled for fighting by reason of their wounds. They fled into the citadel, which, being seated on a commanding height and difficult of access, they continued to defend for some time. As the Macedonians, however, vigorously pressed the attack at all points, while Alexander himself was seen everywhere urging forward the work, the citadel was stormed, and all the men who had fled to it for refuge were put to the sword to the number of 2000.[158] Perdikkas meanwhile reached the city whither he had been sent, but on learning that the inhabitants had not long before fled from it, he rode away at full gallop on the track of the fugitives, while the light troops followed him on foot as fast as they could. Some of the fugitives he overtook and killed, but such as had been too quick for him made their escape to the river marshes.[159] _Chapter VII.—Siege and capture of several Mallian strongholds_ Alexander having dined and allowed his troops to rest till the first watch of the night, began to march forward, and having travelled a great distance in the night, arrived at the river Hydraôtês at daybreak. There he learned that many of the Malloi had already crossed to the other bank, but he fell upon others who were in the act of crossing and slew many of them during the passage. He crossed the river along with them, just as he was, and by the same ford. He then closely pursued the fugitives who had outstripped him in their retreat. Many of these he slew and he captured others, but most of them escaped to a position of great natural strength which was also strongly fortified.[160] But when the infantry came up with him, Alexander sent Peithôn with his own brigade and two squadrons of cavalry against the fugitives. This detachment attacked the stronghold, captured it at the first assault, and made slaves of all who had fled into it, except, of course, those who had fallen in the attack. Then Peithôn and his men, their task fulfilled, returned to the camp.
