The Macedonian cavalry began the action, and destroyed nearly all the chariots of the Indians. Upon this the elephants, applying to good use their prodigious size and strength, killed some of the enemy by trampling them under their feet, and crushing their armour and their bones, while upon others they inflicted a terrible death, for they first lifted them aloft with their trunks, which they had twined round their bodies, and then dashed them down with great violence to the ground. Many others they deprived in a moment of life by goring them through and through with their tusks. But the Macedonians heroically bore the brunt of this dreadful onslaught, and having killed with their long pikes the men stationed between the elephants, made the poise of the battle equal. They next assailed the animals themselves with a storm of javelins, thus piercing them with numerous wounds, which so tortured them that the Indians mounted on their backs lacked sufficient strength to control their movements, for the animals on heading to their own ranks bore against them with an impetuosity not to be repressed, and trampled their own friends under their feet. Then ensued a great confusion, but Pôros, who was mounted on the most powerful of all his elephants, on seeing what had happened, gathered around him forty of the animals that were still under control, and falling upon the enemy with all the weight of the elephants, made a great slaughter with his own hand, for he far surpassed in bodily strength any soldier of his army. In stature he measured five cubits, while his girth was such that his breastplate was twice the size required for a man of ordinary bulk. For this reason the javelins he flung from his hand flew with all but the impetus of shots from a catapult. The Macedonians who stood opposed to him being terror-struck at his astonishing prowess, Alexander sent to their assistance the archers and the divisional light troops, with orders that every man should make Pôros the object of his aim. The soldiers lost no time in carrying out these orders. Their bolts flew thick and fast, and as the Indian king at whom they were all aimed presented a broad mark, none of them failed to carry home. Pôros fought on with heroic courage, but being drained of blood by the number of his wounds, he fainted away, and leaning on his elephant for support, was borne to the ground. A report having spread that their king was dead, the remnant of the Indian host fled from the field, but many of them were slain in the flight. _Chapter LXXXIX.—Losses sustained by each side in the battle of the Hydaspês—Alexander orders a fleet to be built on the Hydaspês._
