After crossing a river some distance farther on, he advanced into the interior parts of India. The forests there extended over an almost boundless tract of country, and abounded with umbrageous trees of stateliest growth, that rose to an extraordinary height. Numerous branches, which for size equalled the trunk of ordinary trees, would bend down to the earth, and then shoot straight up again at the point where they bent upward, so that they had more the appearance of a tree growing from its own root than of a bough branching out from its stem.[258] The climate is salubrious, for the dense shade mitigates the violence of the heat, and copious springs supply the land with abundance of water. But here, also, were multitudes of serpents, the scales of which glittered like gold. The poison of these is deadlier than any other, since their bite was wont to prove instantly fatal, until a proper antidote was pointed out by the natives.[259] From thence they passed through deserts to the river Hyarôtis, the banks of which were covered with a dense forest, abounding with trees not elsewhere seen, and filled with wild peacocks.[260] Decamping hence, he came to a town that lay not far off. This he captured by a general attack all round the walls, and having received hostages, imposed a tribute upon the inhabitants.[261] He came next to a great city—great at least for that region—and found it not only encompassed with a wall, but further defended by a morass.[262] The barbarians nevertheless sallied out to give battle, taking their waggons with them, which they fastened together each to each. For weapons of offence some had pikes and others axes, and they were in the habit of leaping nimbly from waggon to waggon if they saw their friends hard pressed and wished to help them. This mode of fighting being quite new to the Macedonians, at first alarmed them,[263] since they were wounded by enemies beyond their reach, but coming afterwards to look with contempt upon a force so undisciplined, they completely surrounded the waggons and began stabbing all the men that offered resistance. The king then commanded the cords which fastened the waggons together to be cut[264] that it might be easier for the soldiers to beset each waggon separately. The enemy after a loss of 8000 men withdrew into the town.[265] Next day the walls were escaladed all round and captured. A few were indebted for their safety to their swiftness of foot. Those who swam across the sheet of water when they saw the city was sacked, carried great consternation to the neighbouring towns, where they reported that an invincible army, one of gods assuredly, had arrived in the country.
