XXXI. Alexander, after conquering all the country on the higher bank of the Euphrates, marched to attack Darius, who was advancing to meet him with an army of a million fighting men.

During this march, one of Alexander's friends told him as a joke, that the camp-followers had divided themselves into two bodies in sport, each of which was led by a general, the one called Alexander, and the other Darius; and that after beginning to skirmish with one another by throwing clods of earth, they had come to blows of the fist, and had at length become so excited that they fought with sticks and stones, and that it was hard to part them. On hearing this, Alexander ordered the two leaders to fight in single combat: and he himself armed the one called Alexander, while Philotas armed the representative of Darius. The whole army looked on, thinking that the result would be ominous of their own success or failure. After a severe fight, the one called Alexander conquered, and was rewarded with twelve villages and the right of wearing the Persian garb. This we are told by Eratosthenes the historian.

The decisive battle with Darius was fought at Gaugamela, not at Arbela, as most writers tell us. It is said that this word signifies "the house of the camel," and that one of the ancient Kings of Persia, whose life had been saved by the swiftness with which a camel bore him away from his enemies, lodged the animal there for the rest of its life, and assigned to it the revenues of several villages for its maintenance.

During the month Bœdromion, at the beginning of the celebration of the Eleusinian mysteries, there was an eclipse, of the moon: and on the eleventh day after the eclipse the two armies came within sight of one another. Darius kept his troops under arms, and inspected their ranks by torch-light, while Alexander allowed the Macedonians to take their rest, but himself with the soothsayer Aristander performed some mystical ceremonies in front of his tent, and offered sacrifice to Phœbus.

When Parmenio and the elder officers of Alexander saw the entire plain between Mount Niphates and the confines of Gordyene covered with the watch fires of the Persians, and heard the vague, confused murmur of their army like the distant roar of the sea, they were astonished, and said to one another that it would indeed be a prodigious effort to fight such a mass of enemies by daylight in a pitched battle.

As soon as Alexander had finished his sacrifice they went to him, and tried to persuade him to fall upon the Persians by night, as the darkness would prevent his troops from seeing the overwhelming numbers of the enemy. It was then that he made that memorable answer, "I will not steal a victory," which some thought to show an over-boastful spirit, which could jest in the presence of such fearful danger; while others thought that it showed a steady confidence and true knowledge of what would happen on the morrow, and meant that he did not intend to give Darius, when vanquished, the consolation of attributing his defeat to the confusion of a night attack; for Darius had already explained his defeat at Issus to have been owing to the confined nature of the ground, and to his forces having been penned up between the mountains and the sea. It was not any want of men or of arms which would make Darius yield, when he had so vast a country and such great resources at his disposal: it was necessary to make pride and hope alike die within him, by inflicting upon him a crushing defeat in a fair field and in open daylight.

XXXII. After his officers had retired, Alexander retired to his tent and is said to have slept more soundly than was his wont, which surprised the generals who came to wait upon him early in the morning. On their own responsibility they gave orders to the soldiers to prepare their breakfast; and then, as time pressed, Parmenio entered his tent, and standing by his bed-side, twice or thrice called him loudly by name. When he was awake, Parmenio asked him why he slept so soundly, as if he had already won the victory instead of being just about to fight the most important of all his battles. Alexander answered with a smile; "Do you not think we have already won the victory, now that we are no longer obliged to chase Darius over an enormous tract of wasted country?"

Alexander both before the battle, and in the most dangerous crisis of the day proved himself truly great, always taking judicious measures, with a cheerful confidence of success. His left wing was terribly shaken by a tumultuous charge of the Bactrian cavalry, who broke into the ranks of the Macedonians, while Mazæus sent some horsemen completely round the left wing, who fell upon the troops left to guard the baggage. Parmenio, finding his men thrown into confusion by these attacks, sent a message to Alexander, that his fortified camp and baggage would be lost, if he did not at once despatch a strong reinforcement to the rear. At the time when Alexander received this message, he was in the act of giving his own troops orders to attack, and he answered that Parmenio must, in his confusion, have forgotten that the victors win all the property of the vanquished, and that men who are defeated must not think about treasure or prisoners, but how to fight and die with honour. After sending back this answer to Parmenio, he put on his helmet; for he had left his tent fully armed at all other points, wearing a tunic of Sicilian manufacture closely girt round his waist, and over that a double-woven linen corslet, which had been among the spoils taken at Issus. His helmet was of steel, polished as bright as silver, and was wrought by Theophilus, while round his neck he wore a steel gorget, inlaid with precious stones. His sword, his favourite weapon, was a miracle of lightness and tempering, and had been presented to him by the King of Kitium in Cyprus. The cloak which hung from his shoulders was by far the most gorgeous of all his garments, and was the work of the ancient artist Helikon,[410] presented to Alexander by the city of Rhodes, and was worn by him in all his battles. While he was arraying his troops in order of battle, and giving final directions to his officers, he rode another horse to spare Boukephalus, who was now somewhat old. As soon as he was ready to begin the attack, he mounted Boukephalus and led on his army.

XXXIII. Upon this occasion, after addressing the Thessalians and other Greek troops at considerable length, as they confidently shouted to him to lead them against the barbarians, we are told by Kallisthenes that he shifted his lance into his left hand, and raising his right hand to heaven, prayed to the gods that, if he really were the son of Zeus, they would assist and encourage the Greeks. The prophet Aristander, who rode by his side, dressed in a white robe, and with a crown of gold upon his head, now pointed out to him an eagle which rose over his head and directed its flight straight towards the enemy. This so greatly encouraged all who beheld it, that all the cavalry of Alexander's army at once set spurs to their horses and dashed forwards, followed by the phalanx. Before the first of them came to actual blows, the Persian line gave way, and terrible confusion took place, as Alexander drove the beaten troops before him, struggling to fight his way to the centre, where was Darius himself.

Alexander had already noted the conspicuous figure of this tall, handsome prince, as he stood in his lofty chariot, surrounded by the royal body guard, a glittering mass of well-armed horsemen, behind the deep ranks of the Persian army. The onslaught of Alexander was so terrific that none could withstand him, and those whom he drove before him, in headlong flight, disordered the ranks which were yet unbroken, and caused a general rout. Yet the noblest and bravest of the Persians fought and died manfully in defence of their king, and, even when lying on the ground at their last gasp, seized the men and horses by the legs to prevent their pursuing him. Darius himself, seeing all these frightful disasters, when his first line was hurled back in ruin, would fain have turned his chariot and fled, but this was difficult, for the wheels were encumbered by the heaps of corpses, and the horses were so excited and restive that the charioteer was unable to manage them. Darius, we are told, left his chariot and his arms, mounted a mare which had recently foaled, and rode away. He would not have escaped even thus, had not mounted messengers just then arrived from Parmenio, begging Alexander to come to his aid, as he was engaged with a large body of the enemy upon which he could make no impression. Indeed, throughout this battle, Parmenio is said to have displayed great remissness and self-will, either because his courage was damped by age, or because, as we are told by Kallisthenes, he envied Alexander's greatness and prosperity. Alexander was much vexed at the message, but without explaining to the soldiers what his real reasons were, ordered the trumpets to sound the recall, as though he were tired of slaughter, or because night was now coming on. He himself at once rode to the scene of danger, but on his way thither heard that the enemy had been completely defeated and put to flight.
