Not altogether was the young man convinced. He had his moments of conviction; he had his saner phases when the thing was almost a jest. In the presence of Macedonians and Greeks he doubted if he was divine. When it thundered loudly, the ribald Aristarchus could ask him: “Won’t you do something of the sort, oh Son of Zeus?” But the crazy notion was, nevertheless, present henceforth in his brain, ready to be inflamed by wine or flattery.

Next spring (331 B.C.) he returned to Tyre, and marched thence round towards Assyria, leaving the Syrian desert on his right. Near the ruins of forgotten Nineveh he found a great Persian army, that had been gathering since the battle of Issus, awaiting him. It was another huge medley of contingents, and it relied for its chief force upon that now antiquated weapon, the war chariot. Of these Darius had a force of two hundred, and each chariot had scythes attached to its wheels and to the pole and body of the chariot. There seem to have been four horses to each chariot, and it will be obvious that if one of those horses was wounded by javelin or arrow, that chariot was incapacitated. Against broken footmen or a crowd of individualist fighters such vehicles might be formidable; but Darius began the battle by flinging these instruments against the cavalry and light infantry. Few reached their objective, and those that did were readily disposed of. There was some manœuvring for position. The well-drilled Macedonians moved obliquely across the Persian front, keeping good order; the Persians, following this movement to the flank, opened gaps in their array. Then suddenly the disciplined Macedonian cavalry charged at one of these torn places and smote the centre of the Persian host. The infantry followed close upon their charge. The centre and left of the Persians crumpled up. For a while the light cavalry on the Persian right gained ground against Alexander’s left, only to be cut to pieces by the cavalry from Thessaly, which by this time had become almost as good as its Macedonian model. The Persian forces ceased to resemble an army. They dissolved into a vast multitude of fugitives streaming under great dust clouds and without a single rally across the hot plain towards Arbela. Through the dust and the flying crowd rode the victors, slaying and slaying until darkness stayed the slaughter. Darius led the retreat.

Such was the battle of Arbela. It was fought on October the 1st, 331 B.C. We know its date so exactly, because it is recorded that, eleven days before it began, the soothsayers on both sides had been greatly exercised by an eclipse of the moon.

Darius fled to the north into the country of the Medes. Alexander marched on to Babylon. The ancient city of Hammurabi (who had reigned seventeen hundred years before) and of Nebuchadnezzar the Great and of Nabonidus, unlike Nineveh, was still a prosperous and important centre. Like the Egyptians, the Babylonians were not greatly concerned at a change of rule to Macedonian from Persian. The temple of Bel-Marduk was in ruins, a quarry for building material, but the tradition of the Chaldean priests still lingered, and Alexander promised to restore the building. Thence he marched on to Susa, once the chief city of the vanished and forgotten Elamites, and now the Persian capital. He went on to Persepolis, where, as the climax of a drunken carouse, he burnt down the great palace of the king of kings. This he afterwards declared was the revenge of Greece for the burning of Athens by Xerxes.

And now begins a new phase in the story of Alexander. For the next seven years he wandered with an army chiefly of Macedonians in the north and east of what was then the known world. At first it was a pursuit of Darius. Afterwards it became ——? Was it a systematic survey of a world he meant to consolidate into one great order, or was it a wild-goose chase? His own soldiers, his own intimates, thought the latter, and at last stayed his career beyond the Indus. On the map it looks very like a wild-goose chase; it seems to aim at nothing in particular and to get nowhere.

The pursuit of Darius III soon came to a pitiful end. After the battle of Arbela his own generals seem to have revolted against his weakness and incompetence; they made him a prisoner, and took him with them in spite of his desire to throw himself upon the generosity of his conqueror. Bessus, the satrap of Bactria, they made their leader. There was at last a hot and exciting chase of the flying caravan which conveyed the captive king of kings. At dawn, after an all-night pursuit, it was sighted far ahead. The flight became a headlong bolt. Baggage, women, everything was abandoned by Bessus and his captains; and one other impediment also they left behind. By the side of a pool of water far away from the road a Macedonian trooper presently found a deserted mule-cart with its mules still in the traces. In this cart lay Darius, stabbed in a score of places and bleeding to death. He had refused to go on with Bessus, refused to mount the horse that was brought to him. So his captains had run him through with their spears and left him.... He asked his captors for water. What else he may have said we do not know. The historians have seen fit to fabricate a quite impossible last dying speech for him. Probably he said very little....

When, a little after sunrise, Alexander came up, Darius was already dead....

To the historian of the world the wanderings of Alexander have an interest of their own quite apart from the light they throw upon his character. Just as the campaign of Darius I lifted the curtain behind Greece and Macedonia, and showed us something of the silent background to the north of the audible and recorded history of the early civilizations, so now Alexander’s campaigns take us into regions about which there had hitherto been no trustworthy record made.

We discover they were not desert regions, but full of a gathering life of their own.
