Arrangements of Porus.
Ptolemy also says that Alexander in the first place sent the horse-archers against these, and led the cavalry himself, thinking that Porus was approaching with all his forces, and that this body of cavalry was marching in front of the rest of his army, being drawn up by him as the vanguard. But as soon as he had ascertained with accuracy the number of the Indians, he immediately made a rapid charge upon them with the cavalry around him. When they perceived that Alexander himself and the[289] body of cavalry around him had made the assault, not in line of battle regularly formed, but by squadrons, they gave way; and 400 of their cavalry, including the son of Porus, fell in the contest. The chariots also were captured, horses and all, being heavy and slow in the retreat, and useless in the action itself on account of the clayey ground. When the horsemen who had escaped from this rout brought news to Porus that Alexander himself had crossed the river with the strongest part of his army, and that his son had been slain in the battle, he nevertheless could not make up his mind what course to take, because the men who had been left behind under Craterus were seen to be attempting to cross the river from the great camp which was directly opposite his position. However, at last he preferred to march against Alexander himself with all his army, and to come into a decisive conflict with the strongest division of the Macedonians, commanded by the king in person. But nevertheless he left a few of the elephants together with a small army there at the camp to frighten the cavalry under Craterus from the bank of the river. He then took all his cavalry to the number of 4,000 men, all his chariots to the number of 300, with 200 of his elephants and 30,000 choice infantry, and marched against Alexander. When he found a place where he saw there was no clay, but that on account of the sand the ground was all level and hard, and thus fit for the advance and retreat of horses, he there drew up his army. First he placed the elephants in the front, each animal being not less than a plethrum[683] apart, so that they might be extended in the front before the whole of the phalanx of infantry, and produce terror everywhere among Alexander’s cavalry. Besides he thought that none of the enemy would have the audacity to push themselves into the spaces between [290]the elephants, the cavalry being deterred by the fright of their horses; and still less would the infantry do so, it being likely they would be kept off in front by the heavy-armed soldiers falling upon them, and trampled down by the elephants wheeling round against them. Near these he had posted the infantry, not occupying a line on a level with the beasts, but in a second line behind them, only so far distant that the companies of foot might be pushed forward a short distance into the spaces between them. He had also bodies of infantry standing beyond the elephants on the wings; and on both sides of the infantry he had posted the cavalry, in front of which were placed the chariots on both wings of his army.
CHAPTER XVI.
Alexander’s Tactics.
Such was the arrangement which Porus made of his forces. As soon as Alexander observed that the Indians were drawn up in order of battle, he stopped his cavalry from advancing farther, so that he might take up the infantry as it kept on arriving; and even when the phalanx in quick march had effected a junction with the cavalry, he did not at once draw it out and lead it to the attack, not wishing to hand over his men exhausted with fatigue and out of breath, to the barbarians who were fresh and untired. On the contrary, he caused his infantry to rest until their strength was recruited, riding along round the lines to inspect them.[684] When he had surveyed the arrangement of the Indians, he resolved not to advance against the centre, in front of which the elephants had been posted, and in the gaps between them a dense phalanx of men; for he was alarmed at the very arrangements which Porus had made here with that express design. But as he was superior in the number [291]of his cavalry, he took the greater part of that force, and marched along against the left wing of the enemy for the purpose of making an attack in this direction. Against the right wing he sent Coenus with his own regiment of cavalry and that of Demetrius, with instructions to keep close behind the barbarians when they, seeing the dense mass of cavalry opposed to them, should ride out to fight them. Seleucus, Antigenes, and Tauron were ordered to lead the phalanx of infantry, but not to engage in the action until they observed[685] the enemy’s cavalry and phalanx of infantry thrown into disorder by the cavalry under his own command. But when they came within range of missiles, he launched the horse-archers, 1000 in number, against the left wing of the Indians, in order to throw those of the enemy who were posted there into confusion by the incessant storm of arrows and by the charge of the horses. He himself with the Companion cavalry marched along rapidly against the left wing of the barbarians, being eager to attack them in flank while still in a state of disorder, before their cavalry could be deployed.
CHAPTER XVII.
Defeat of Porus.
Meantime the Indians had collected their cavalry from all parts, and were riding along, advancing out of their position to meet Alexander’s charge. Coenus also appeared with his men in their rear, according to his instructions. The Indians, observing this, were compelled to make the line of their cavalry face both ways[686]; the largest and best part against Alexander, while the rest wheeled round against Coenus and his forces. This therefore at once threw the ranks as well as the decisions of the Indians [292]into confusion. Alexander, seeing his opportunity, at the very moment the cavalry was wheeling round in the other direction, made an attack on those opposed to him with such vigour that the Indians could not sustain the charge of his cavalry, but were scattered and driven to the elephants, as to a friendly wall, for refuge. Upon this, the drivers of the elephants urged forward the beasts against the cavalry; but now the phalanx itself of the Macedonians was advancing against the elephants, the men casting darts at the riders and also striking the beasts themselves, standing round them on all sides. The action was unlike any of the previous contests; for wherever the beasts could wheel round, they rushed forth against the ranks of infantry and demolished the phalanx of the Macedonians, dense as it was. The Indian cavalry also, seeing that the infantry were engaged in the action, rallied again and advanced against the Macedonian cavalry. But when Alexander’s men, who far excelled both in strength and military discipline, got the mastery over them the second time, they were again repulsed towards the elephants and cooped up among them. By this time the whole of Alexander’s cavalry had collected into one squadron, not by any command of his, but having settled into this arrangement by the mere effect of the struggle itself; and wherever it fell upon the ranks of the Indians they were broken up with great slaughter. The beasts being now cooped up into a narrow space, their friends were no less injured by them than their foes, being trampled down in their wheeling and pushing about. Accordingly there ensued a great slaughter of the cavalry, cooped up as it was in a narrow space around the elephants. Most of the keepers of the elephants had been killed by the javelins, and some of the elephants themselves had been wounded, while others no longer kept apart in the battle on account of their sufferings or from being destitute of keepers. But, as if frantic with[293] pain, rushing forward at friends and foes alike, they pushed about, trampled down and killed them in every kind of way. However, the Macedonians retired whenever they were assailed, for they rushed at the beasts in a more open space, and in accordance with their own plan; and when they wheeled round to return, they followed them closely and hurled javelins at them; whereas the Indians retreating among them were now receiving greater injury from them. But when the beasts were tired out, and they were no longer able to charge with any vigour, they began to retire, facing the foe like ships backing water, merely uttering a shrill piping sound. Alexander himself surrounded the whole line with his cavalry, and gave the signal that the infantry should link their shields together so as to form a very densely closed body, and thus advance in phalanx. By this means the Indian cavalry, with the exception of a few men, was quite cut up in the action; as was also the infantry, since the Macedonians were now pressing upon them from all sides. Upon this, all who could do so turned to flight through the spaces which intervened between the parts of Alexander’s cavalry.
