Here there fell a most violent storm of rain, accompanied with lightning and whirlwinds, and seeing some of his men burnt and dying with the lightning, he nevertheless quitted the island and made over to the other side. The Hydaspes, he says, now after the storm, was so swollen and grown so rapid as to have made a breach in the bank, and a part of the river was now pouring in here, so that when he came across it was with difficulty he got a footing on the land, which was slippery and unsteady, and exposed to the force of the currents on both sides. This is the occasion when he is related to have said, "Oye Athenians, will ye believe what dangers I incur to merit your praise?" This, however, is Onesicritus's story. Alexander says, here the men left their boats, and passed the breach in their armour, up to the breast in water, and that then he advanced with his horse about twenty furlongs before his foot, concluding that if the enemy charged him with their cavalry he should be too strong for them; if with their foot, his own would come up time enough to his assistance. Nor did he judge amiss; for being charged by a thousand horse and sixty armed chariots, which advanced before their main body, he took all the chariots, and killed four hundred horse upon the place. Porus, by this time, guessing that Alexander himself had crossed over, came on with his whole army, except a party which he left behind, to hold the rest of the Macedonians in play, if they should attempt to pass the river. But he, apprehending the multitude of the enemy, and to avoid the shock of their elephants, dividing his forces, attacked their left wing himself, and commanded Coenus to fall upon the right, which was performed with good success. For by this means both wings being broken, the enemies fell back in their retreat upon the centre, and crowded in upon their elephants.
There rallying, they fought a hand-to-hand battle, and it was the eighth hour of the day before they were entirely defeated. This description the conqueror himself has left us in his own epistles.
Almost all the historians agree in relating that Porus was four cubits and a span high, and that when he was upon his elephant, which was of the largest size, his stature and bulk were so answerable, that he appeared to be proportionately mounted, as a horseman on his horse. This elephant, during the whole battle, gave many singular proofs of sagacity and of particular care of the king, whom as long as he was strong and in a condition to fight, he defended with great courage, repelling those who set upon him; and as soon as he perceived him overpowered with his numerous wounds and the multitude of darts that were thrown at him, to prevent his falling off, he softly knelt down and began to draw out the darts with his proboscis. When Porus was taken prisoner, and Alexander asked him how he expected to be used, he answered, "As a king." For that expression, he said, when the same question was put to him a second time, comprehended everything. And Alexander, accordingly, not only suffered him to govern his own kingdom as satrap under himself, but gave him also the additional territory of various independent tribes whom he subdued, a district which, it is said, contained fifteen several nations, and five thousand considerable towns, besides abundance of villages. To another government, three times as large as this, he appointed Philip, one of his friends.
Some little time after the battle with Porus, Bucephalus died, as most of the authorities state, under cure of his wounds, or, as Onesicritus says, of fatigue and age, being thirty years old.
Alexander was no less concerned at his death than if he had lost an old companion or an intimate friend, and built a city, which he named Bucephalia, in memory of him, on the bank of the river Hydaspes.
He also, we are told, built another city, and called it after the name of a favourite dog, Peritas, which he had brought up himself. So Sotion assures us he was informed by Potamon of Lesbos.
But this last combat with Porus took off the edge of the Macedonians' courage, and stayed their further progress into India.
