country advanced towards the Hydaspês.[96] _Chapter IX.—Alexander on reaching the Hydaspês finds Pôros prepared to dispute its passage_ Alexander encamped on the banks of the river,[97] and Pôros was seen on the opposite side, with all his army and his array of elephants around him.[98] Against the place where he saw Alexander had encamped, he remained himself to guard the passage, but he sent detachments of his men, each commanded by a captain, to guard all parts of the river where it could be easily forded, as he was resolved to prevent the Macedonians from effecting a landing. When Alexander saw this, he thought it expedient to move his army from place to place, so that Pôros might be at a loss to discover his real intentions. For this purpose he divided his army into many parts, and some of the troops he led himself in different directions, sometimes to ravage the enemy’s country, and sometimes to find out where he could most easily ford the river. He placed various commanders at various times over different divisions of his army, and despatched them also in different directions. At the same time he caused provisions to be conveyed to the camp from all parts of the country on this side of the river, to impress Pôros with the conviction that he intended to remain where he was near the bank, till the waters of the river subsided in winter, and afforded him a large choice of passages. As the boats were constantly plying up and down the stream, and the skins were being filled with hay, while all the bank was lined, here with horse and there with foot, all this prevented Pôros from resting and concentrating his preparations at any one point selected in preference to any other as the best for defending the passage. At this time of the year besides, all the Indian rivers were swollen and flowing with turbid and rapid currents, for the sun is then wont to turn towards the summer tropic.[99] At this season incessant rains deluge the soil of India, and the snows of the Kaukasos then melting flood the numerous rivers to which they give birth. In winter they again subside and become small and clear, and in many places fordable, with the exception of the Indus and the Ganges, and perhaps some one or two others. The Hydaspês at all events does become fordable. _Chapter X.—Alexander’s devices to deceive Pôros and steal the passage of the river_
