Although Alexander had been so completely victorious over his enemies on the day of battle, and had maintained his ground against them with such invincible power, he was, nevertheless, a few days afterward, driven entirely off the field, and completely away from the region where the battle had been fought. What the living men, standing erect in arms, and full of martial vigor, could not do, was easily and effectually accomplished by their dead bodies corrupting on the plain. The corpses of three hundred thousand men, and an equal bulk of the bodies of elephants and horses, was too enormous a mass to be buried. It had to be abandoned; and the horrible effluvia and pestilence which it emitted drove all the inhabitants of the country away. Alexander marched his troops rapidly off the ground, leaving, as the direct result of the battle, a wide extent of country depopulated and desolate, with this vast mass of putrefaction and pestilence reigning in awful silence and solitude in the midst of it.

March to Babylon.

Alexander went to Babylon. The governor of the city prepared to receive him as a conqueror. The people came out in throngs to meet him, and all the avenues of approach were crowded with spectators. All the city walls, too, were covered with men and women, assembled to witness the scene. As for Alexander himself, he was filled with pride and pleasure at thus arriving at the full accomplishment of his earliest and long-cherished dreams of glory.

Surrender of Susa.
Plunder of the palace.
Wholesale robbery and murder.
Immense treasures.

The great store-house of the royal treasures of Persia was at Susa, a strong city east of Babylon. Susa was the winter residence of the Persian kings, as Ecbatana, further north, among the mountains, was their summer residence. There was a magnificent palace and a very strong citadel at Susa, and the treasures were kept in the citadel. It is said that in times of peace the Persian monarchs had been accustomed to collect coin, melt it down, and cast the gold in earthen jars. The jars were afterward broken off from the gold, leaving the bullion in the form of the interior of the jars. An enormous amount of gold and silver, and of other treasures, had been thus collected. Alexander was aware of this depository before he advanced to meet Darius, and, on the day of the battle of Arbela, as soon as the victory was decided, he sent an officer from the very field to summon Susa to surrender. They obeyed the summons, and Alexander, soon after his great public entrance into Babylon, marched to Susa, and took possession of the vast stores of wealth accumulated there. The amount was enormous, both in quantity and value, and the seizing of it was a very magnificent act of plunder. In fact, it is probable that Alexander's slaughter of the Persian army at Arbela, and subsequent spoliation of Susa, constitute, taken together, the most gigantic case of murder and robbery which was ever committed by man; so that, in performing these deeds, the great hero attained at last to the glory of having perpetrated the grandest and most imposing of all human crimes. That these deeds were really crimes there can be no doubt, when we consider that Alexander did not pretend to have any other motive in this invasion than love of conquest, which is, in other words, love of violence and plunder. They are only technically shielded from being called crimes by the fact that the earth has no laws and no tribunals high enough to condemn such enormous burglaries as that of one quarter of the globe breaking violently and murderously in upon and robbing the other.

Besides the treasures, Alexander found also at Susa a number of trophies which had been brought by Xerxes from Greece; for Xerxes had invaded Greece some hundred years before Alexander's day, and had brought to Susa the spoils and the trophies of his victories. Alexander sent them all back to Greece again.

Pass of Susa.
The mountaineers.

From Susa the conqueror moved on to Persepolis, the great Persian capital. On his march he had to pass through a defile of the mountains. The mountaineers had been accustomed to exact tribute here of all who passed, having a sort of right, derived from ancient usage, to the payment of a toll. They sent to Alexander when they heard that he was approaching, and informed him that he could not pass with his army without paying the customary toll. Alexander sent back word that he would meet them at the pass, and give them their due.

They understood this, and prepared to defend the pass. Some Persian troops joined them. They built walls and barricades across the narrow passages. They collected great stones on the brinks of precipices, and on the declivities of the mountains, to roll down upon the heads of their enemies. By these and every other means they attempted to stop Alexander's passage. But he had contrived to send detachments around by circuitous and precipitous paths, which even the mountaineers had deemed impracticable, and thus attack his enemies suddenly and unexpectedly from above their own positions. As usual, his plan succeeded. The mountaineers were driven away, and the conqueror advanced toward the great Persian capital.
