Darius was now a fugitive, with the mere title of king, and with a simple body-guard rather than an army. On leaving Arbêla after the defeat, he had struck in an easterly direction across the mountains into Media; having only a few attendants round him, and thinking himself too happy to preserve his own life from an indefatigable pursuer.[428] He calculated that, once across these mountains, Alexander would leave him for a time unmolested, in haste to march southward for the purpose of appropriating the great and real prizes of the campaign—Babylon, Susa, and Persepolis. The last struggles of this ill-starred prince will be recounted in another chapter. [428] Arrian, iii. 16, 1-4. CHAPTER XCIV. MILITARY OPERATIONS AND CONQUESTS OF ALEXANDER, AFTER HIS WINTER-QUARTERS IN PERSIS, DOWN TO HIS DEATH AT BABYLON. From this time forward to the close of Alexander’s life—a period of about seven years—his time was spent in conquering the eastern half of the Persian empire, together with various independent tribes lying beyond its extreme boundary. But neither Greece, nor Asia Minor, nor any of his previous western acquisitions, was he ever destined to see again. Now, in regard to the history of Greece—the subject of these volumes—the first portion of Alexander’s Asiatic campaigns (from his crossing the Hellespont to the conquest of Persis, a period of four years, March 334 B. C., to March 330 B. C.), though not of direct bearing, is yet of material importance. Having in his first year completed the subjugation of the Hellenic world, he had by these subsequent campaigns absorbed it as a small fraction into the vast Persian empire, renovated under his imperial sceptre. He had accomplished a result substantially the same as would have been brought about if the invasion of Greece by Xerxes, destined, a century and a half before, to incorporate Greece with the Persian monarchy, had succeeded instead of failing.[429] Towards the kings of Macedonia alone, the subjugation of Greece would never have become complete, so long as she could receive help from the native Persian kings, who were perfectly adequate as a countervailing and tutelary force, had they known how to play their game. But all hope for Greece from without was extinguished, when Babylon, Susa, and Persepolis became subject to the same ruler as Pella and Amphipolis—and that ruler too, the ablest general, and most insatiate aggressor, of his age; to whose name was attached the prestige of success almost superhuman. Still, against even this overwhelming power, some of the bravest of the Greeks at home tried to achieve their liberation with the sword: we shall see presently how sadly the attempt miscarried. [429] Compare the language addressed by Alexander to his weary soldiers, on the banks of the Hyphasis (Arrian, v. 26), with that which Herodotus puts into the mouth of Xerxes, when announcing his intended expedition against Greece (Herodot. vii. 8).
