LX. His campaign against king Porus is described at length in his own letters. He tells us that the river Hydaspes[421] ran between the two camps, and that Porus with his elephants watched the further bank, and prevented his crossing. Alexander himself every day caused a great noise and disturbance to be made in his camp, in order that the enemy might be led to disregard his movements: and at last upon a dark and stormy night he took a division of infantry and the best of the cavalry, marched to a considerable distance from the enemy, and crossed over into an island of no great extent. Here he was exposed to a terrible storm of rain, with thunder and lightning; but, although several of his men were struck dead, he pressed on, crossed the island, and gained the furthermost bank of the river. The Hydaspes was flooded by the rain, and the stream ran fiercely down this second branch, while the Macedonians could with difficulty keep their footing upon this slippery and uneven bottom Here it was that Alexander is said to have exclaimed, "O ye Athenians, what toils do I undergo to obtain your praise."

This, however, rests only on the authority of the historian Oneskritus, for Alexander himself relates that they abandoned their rafts, and waded through this second torrent under arms, with the water up to their breasts. After crossing, he himself rode on some twenty furlongs in advance of the infantry, thinking that if the enemy met him with their cavalry alone, he would be able to rout them easily, and that, if they advanced their entire force, before a battle could be begun, he would be joined by his own infantry. And indeed he soon fell in with a thousand horse and sixty war chariots of the enemy, which he routed, capturing all the chariots, and slaying four hundred of the horsemen. Porus now perceived that Alexander himself had crossed the river, and advanced to attack him with all his army, except only a detachment which he left to prevent the Macedonians from crossing the river at their camp. Alexander, alarmed at the great numbers of the enemy, and at their elephants, did not attack their centre, but charged them on the left wing, ordering Koinus to attack them on the right. The enemy on each wing were routed, but retired towards their main body, where the elephants stood. Here an obstinate and bloody contest took place, insomuch that it was the eighth hour of the day before the Indians were finally overcome. These particulars we are told by the chief actor in the battle himself, in his letters. Most historians are agreed that Porus stood four cubits[422] and a span high, and was so big a man that when mounted on his elephant, although it was a very large one, he seemed as well proportioned to the animal as an ordinary man is to a horse. This elephant showed wonderful sagacity and care for its king, as while he was still vigorous it charged the enemy and overthrew them, but when it perceived that he was fainting from his wounds, fearing that he might fall, it quietly knelt on the ground, and then gently drew the spears out of his body with its trunk. When Porus was captured, Alexander asked him how he wished to be treated. "Like a king," answered Porus. Alexander then enquired if he had nothing else to ask about his treatment. "Everything," answered Porus, "is comprised in these words, like a king." Alexander now replaced Porus in his kingdom, with the title of satrap, and also added a large province to it, subduing the independent inhabitants. This country was said to have contained fifteen separate tribes, five thousand considerable cities and innumerable villages; besides another district three times as large, over which he appointed Philippus, one of his personal friends, to be satrap.

LXI. After this battle with Porus, Alexander's horse Boukephalus died, not immediately, but some time afterwards. Most historians say that he died of wounds received in the battle, but Onesikritus tells us that he died of old age and overwork, for he had reached his thirtieth year. Alexander was greatly grieved at his loss, and sorrowed for him as much as if he had lost one of his most intimate friends. He founded a city as a memorial of him upon the banks of the Hydaspes, which he named Boukephalia. It is also recorded that when he lost a favourite dog called Peritas, which he had brought up from a whelp, and of which he was very fond, he founded a city and called it by the dog's name. The historian Sotion tells us that he heard this from Potamon of Lesbos.

LXII. The battle with King Porus made the Macedonians very unwilling to advance farther into India. They had overcome Porus with the greatest difficulty, as he brought against them a force of twenty thousand infantry and two thousand cavalry, and now offered the most violent opposition to Alexander, who wished to cross the river Ganges. This river, they heard, was thirty-two furlongs wide and a hundred cubits deep, while its further banks were completely covered with armed men, horses and elephants, for it was said that the kings of the Gandaritæ and Præsiæ were awaiting his attack with an army of eighty thousand horsemen, two hundred thousand foot soldiers, eight thousand war chariots, and six thousand elephants; nor was this any exaggeration, for not long afterwards Androkottus, the king of this country, presented five hundred elephants to Seleukus, and overran and subdued the whole of India with an army of six hundred thousand men.

Alexander at first retired to his tent in a rage, and shut himself up there, not feeling any gratitude to those who had prevented his crossing the Ganges, but regarding a retreat as an acknowledgment of defeat. However, after his friends had argued with him, and his soldiers had come to the door of his tent, begging him with tears in their eyes to go no farther, he relented, and gave orders for a retreat. He now contrived many ingenious devices to impress the natives, as, for instance, he caused arms, and bridles and mangers for horses to be made of much more than the usual size, and left them scattered about. He also set up altars, which even to the present day are reverenced by the kings of the Præsiæ, who cross the river to them, and offer sacrifice upon them in the Greek fashion. Androkottus himself, who was then a lad, saw Alexander himself and afterwards used to declare that Alexander might easily have conquered the whole country, as the then king was hated by his subjects on account of his mean and wicked disposition.

LXIII. After this, Alexander wishing to see the outer ocean,[423] caused many rafts and vessels managed with oars to be built, and proceeded in a leisurely manner down the Indus. His voyage, however, was not an idle one, nor was it unaccompanied with danger, for as he passed down the river, he disembarked, attacked the tribes on the banks, and subdued them all. When he was among the Malli, who are said to be the most warlike tribe in India, he very nearly lost his life. He was besieging their chief city, and after the garrison had been driven from the walls by volleys of missiles, he was the first man to ascend a scaling ladder and mount the walls. The ladder now broke, so that no more could mount, and as the enemy began to assemble inside at the foot of the wall and shoot up at him from below, Alexander, alone against a host, leaped down amongst them, and by good luck, alighted on his feet. His armour rattled loudly as he leaped, and made the natives think that a bright light was emitted from his body; so that at first they gave way and fled from him. But when they saw that he was attended by only two followers, some of them attacked him at close quarters with swords and spears, while one standing a little way off shot an arrow at him with such force and with such good aim, that it passed through his corslet and imbedded itself in the bones of his breast. As he shrank back when the arrow struck him, the man who had shot it ran up to him with a drawn sword in his hand. Peukestas and Limnæus now stood before Alexander to protect him. Both were wounded, Limnæus mortally; but Peukestas managed to stand firm, while Alexander despatched the Indian with his own hand. Alexander was wounded in many places, and at last received a blow on the neck with a club, which forced him to lean his back against the wall, still facing the enemy. The Macedonians now swarmed round him, snatched him up just as he fainted away, and carried him insensible to his tent. A rumour now ran through the camp that he was dead, and his attendants with great difficulty sawed through the wooden shaft of the arrow, and so got off his corslet. They next had to pluck out the barbed head of the arrow, which was firmly fixed in one of his ribs. This arrow-head is said to have measured four fingers-breadths[424] in length, and three in width. When it was pulled out, he swooned away, so that he nearly died, but at length recovered his strength. When he was out of danger, though still very weak, as he had to keep himself under careful treatment for a long time, he heard a disturbance without, and learning that the Macedonians were anxious to see him, took his cloak and went out to them. After sacrificing to the gods for the recovery of his health, he started again on his journey, and passed through a great extent of country and past many considerable cities, all of which he subdued.

LXIV. He captured ten of the Indian philosophers called Gymnosophistæ;[425] who had been instrumental in causing Sabbas to revolt, and had done much mischief to the Macedonians. These men are renowned for their short, pithy answers, and Alexander put difficult questions to all of them, telling them that he would first put to death the man who answered him worst, and so the rest in order. The first was asked, whether he thought the living or the dead to be the more numerous. He answered, "The living, for the dead are not."

The second was asked, which breeds the largest animals, the sea or the land. He answered, "The land, for the sea is only a part of it."

The third was asked, which is the cleverest of beasts. He answered, "That which man has not yet discovered."

The fourth was asked why he made Sabbas rebel. He answered, "Because I wished him either to live or to die with honour."
