Chapter XXI · —Pursuit after Pôros, nephew of the great Pôros—Conquest of the country between the Akesinês and the Hydraôtês—Passage of the latter river

After crossing the river he left Koinos there upon the bank with his own brigade, and ordered him to superintend the passage of the river by those troops which had been left behind to collect corn and other supplies from the part of India which was now under his authority. Pôros he sent home to his capital with orders to select the best fighting men of the Indians, and to muster all the elephants he possessed, and to rejoin him with these. He resolved to pursue in person the other Pôros—the bad one—with the lightest troops in his army, for word had been brought that he had fled from the country of which he was the ruler; for, while hostilities still subsisted between Alexander and the other Pôros, this Pôros had sent envoys to Alexander offering to surrender into his hands both his person and the country over which he ruled, but this more from enmity to Pôros than friendliness to Alexander. On learning therefore that Pôros had not only been set at liberty, but had his kingdom restored to him, and that too with a large accession of territory, he was overcome with fear, not so much of Alexander as of his namesake Pôros, and fled from his country, taking with him as many fighting men as he could persuade to accompany him in his flight.

Alexander, while marching to overtake him, arrived at the Hydraôtês—another Indian river, not less in breadth than the Akesinês, but not so rapid.[123] Over all the country which he overran he planted garrisons in the most suitable places, so that the troops under Krateros and Koinos might, while scouring it far and near for forage, traverse it in safety to join him. He then despatched Hêphaistiôn with a force comprising two divisions of infantry, his own regiment of cavalry and that of Dêmêtrios, and one-half of the archers, into the country of that Pôros who had revolted. He received orders to hand over the country to the other Pôros, and when he had reduced all the independent Indian tribes bordering on the banks of the Hydraôtês, to place these also under the rule of Pôros. He himself then crossed the river Hydraôtês, where he met with none of the difficulties which had attended the passage of the Akesinês. When he was advancing into the country beyond the Hydraôtês he found most of the natives willing to surrender on capitulation, while some met him in arms, and others were captured when attempting to escape and reduced to submission.
