The Macedonians had now reached a fertile country; but as Bessos had ordered it to be ravaged, they found a wide barrier of desolation opposed to their further advance. The barrier was interposed in vain. Alexander resolutely pressed forward, and Bessos and his associates fled at his approach, and, crossing the Oxus, retired into Sogdiana. Aornos and Baktra, the two principal cities of the Baktrian satrapy, surrendered without resistance, and the satrapy itself was soon afterwards reduced. At Baktra Erigyios, who had succeeded in quelling the Areian revolt, rejoined the army. Alexander having appointed Artabazos satrap of his new conquest, marched to the Oxus in pursuit of Bessos, and came upon that river at the point where Kijil now stands. There it was about three-quarters of a mile in breadth, and the current was found to be both deep and rapid. The passage, which occupied five days, was made on floats, supported by skins stuffed with straw, and rendered watertight. The army had no sooner gained the right bank than messengers arrived from two of the leading adherents of Bessos—Spitamenes, the satrap of Sogdiana, and Dataphernes—promising to surrender Bessos, who was already their prisoner, if Alexander would send a small force to their support. The king assented, and sent Ptolemy forward to receive the traitor from their hands. They gave him up, and he was conducted with a rope round his neck into the presence of the king, who ordered him to be scourged and then conveyed to Zariaspa (which some identify with Baktra), there to await his final doom.

The army next marched forward to Marakanda, now Samarkand, then merely the capital of the Sogdian satrapy, but destined to be in aftertimes the capital of the vast empire founded by Timour. It stood in the valley of the Polytimêtos (R. Kohik), a region of such exuberant fertility and beauty that it figures in Persian poetry as one of the four paradises of the world. Alexander remained for some time in this pleasant neighbourhood to remount his cavalry and otherwise recruit his forces. He then advanced to the river Jaxartes, which formed the boundary between the Persian empire and the barbarous Skythian tribes, and which the Greeks confounded with the Tanais or Don. The country was protected against the inroads of these warlike tribes by a line of fortified towns, of which the largest and strongest, Cyropolis, had been founded, as its name imports, by Cyrus. Alexander captured all these fortresses and manned them with small Macedonian garrisons; and to curb the Skythians still more effectually, founded on the banks of the Jaxartes, near where Khojent now stands, still another Alexandreia, which the Greeks for distinction’s sake called Eschatê, or “the Extreme.” In the midst of this undertaking, he was interrupted by the sudden outbreak of a widespread rebellion instigated by Spitamenes and his confederates. Taking immediate and energetic steps for its suppression, he in a few days recovered the seven towns; and then crossing the Jaxartes, defeated the Skythians, who with a view to aid the insurgents had mustered in great force on its right bank. After this victory he received tidings of the first serious disaster that had befallen his arms. He had sent a large force to operate against Spitamenes, who was at the time besieging the Macedonian garrison which held Marakanda. On learning that this force was approaching, the rebel chief retired down the Polytimêtos to Bokhara, and thence to the vast desert which stretches from Sogd to the Sea of Aral. Here he was joined by a large body of Skythian horsemen, and thus reinforced turned upon his pursuers, drove them back from the edge of the desert, which they had just entered, into the valley whence they had emerged, and there, amid the woody ravines of the Polytimetos, cut them to pieces almost to a man. Encouraged by this success, he returned to Marakanda and renewed the siege of its citadel, but on learning that Alexander was rapidly returning from the Jaxartes, he retraced his steps towards the desert, and reached it before the enemy overtook him. The course of the pursuit led Alexander to the scene of the late disaster. His first care was to bury the slain, and he then avenged their death by ravaging with fire and sword, in all its length and breadth, the lovely valley of the Polytimetos. He showed no mercy, but slaughtered all who fell into his hands, soldier and citizen alike. This is certainly, as Thirlwall remarks, one of the acts of his life for which it is most difficult to find an excuse.

As the year (329 B.C.) was now drawing to a close, he recrossed the Oxus and returned to Zariaspa (Baktra?), where he spent the winter. Sentence was here pronounced upon Bessos, who was mutilated and then sent to Ekbatana for execution. Alexander’s European forces, as the narrative has shown, were constantly undergoing diminution, not only by losses in the field, but also by his leaving Macedonian veterans to garrison important strongholds, or to form the nucleus of the population of the cities he founded. He therefore from time to time sent requisitions for recruits to Macedonia and Greece, and as these were adequately met the fighting quality of his troops was always maintained at the same high level. During his stay at Baktra a great number of such recruits arrived, and filled up the large gap which the late disaster had made in his ranks. There came thither also ambassadors from the King of the Skythians, bringing presents and the offer of a marriage alliance, which was declined. The King of the Khorasmians, moreover, whose dominions, according to his own account, bordered on the land of the Kolchians and the Amazons, came in person and offered his services to Alexander should he wish to subdue the nations to the north and west of the Kaspian Sea. Alexander, however, being now anxious to enter India, declined his offers for the present.

The accounts of his next two campaigns are confused, and not always mutually consistent. According to Curtius, when he moved from Zariaspa, he crossed the river Ochos (now the Aksou), and came to a city called Marginia, probably the Marginan of our times. Arrian, however, makes no mention of this expedition. The Baktrians were still imperfectly subjugated, and the Sogdians, notwithstanding the severe chastisement they had received, were again up in arms against his authority. He therefore left Krateros to deal with the former, while he marched in person against Marakanda. On his way thither he performed another of his marvellous achievements, the capture of a fortress perched on the summit of a steep, lofty, and strongly fortified rock, held by a powerful garrison, and deemed to be impregnable. He captured it, nevertheless. Within this stronghold Oxyartes, a Baktrian chief, had for safety deposited his wife and daughters. Roxana, the eldest daughter, was, next to the wife of Darius, the most beautiful of all Asiatic women, and Alexander was so captivated with her charms that he did not hesitate to make her his wife.

Spitamenes, meanwhile, assisted by the Massagetai, one of the Skythian tribes that ranged over the Khorasmian desert, made a devastating irruption into Baktria, and though he was in the end repulsed by Krateros, escaped into the desert beyond the reach of pursuit. Fearing he might renew his attack in some other quarter, Alexander hastened to Marakanda to settle the province and provide for its security against future hostile incursions. To this end he directed a number of new towns to be founded and planted with Macedonian, Greek, and native colonists. In the course of this expedition he came to the Royal Park at Bazaria (perhaps Bokhara), and while hunting within its precincts killed a lion of extraordinary size with his own hand.

On his return to Marakanda a tragic incident occurred—his murder of Kleitos, from whom he had received some provocation in the course of a drunken revel. As he was tenderly attached to Kleitos, who was the brother of his nurse, and had saved his life at the Granîkos, his remorse for this frenzied deed knew no bounds at the time, and gave him many bitter moments in his after life.

His next expedition led him towards the western frontier of the province, where he reduced the district called Xenippa, which lay on the skirts of the Noura mountains—a range that runs from east to west about ten miles north of Bokhara. As Spitamenes was supposed to be in the desert not far off, he left Koinos in that part of the country with orders to capture that audacious rebel, while he himself withdrew to Nautaka, where he intended to pass the winter. This place was situated in a fertile oasis between Samarkand and the Oxus, and must have occupied the site of Kurshee or Kesh, noted afterwards as the birthplace of Timour. Spitamenes, meanwhile, attacked Koinos, but was defeated after a severe struggle, and driven back into the desert. His Skythian confederates, fearing their own country might be invaded, cut off his head and sent it to Alexander; and so perished the most active, bold, and persevering antagonist that he had as yet encountered in Asia, one of the few who resolutely and to the last scorned to bend his neck to a foreign yoke.

With the first return of spring (B.C. 327) he moved from his winter quarters to invade the Paraitakai, who, as their name indicates, inhabited a mountainous district, and were, some think, a branch of the widespread Takka tribe, the name of which appears in Taxila, which designated a great capital it possessed in India. In the country of the Paraitakai, which lay to the east of Baktria and Sogdiana, there was another great rock fortress, which, like the Sogdian, was deemed impregnable. It was the main stronghold of a chief called Khorienês, who, after holding out for some time, was persuaded by Oxyartes to cast himself on the generosity of the great conqueror, a quality of which he had himself a very satisfactory experience. Khoriênes therefore surrendered, and was rewarded by being confirmed in his government. Alexander after this success proceeded to Baktra in order to make preparation for his expedition into India, but left Krateros to reduce such of the tribes as still held out for independence. At Baktra another tragedy was enacted. The court pages, at the instigation of one of their number, called Hermolaos, who had been subjected to some degrading punishment, conspired against the king, who narrowly escaped assassination. The pages, who all belonged to families of high rank, were tortured to extract confessions of their guilt, and were then stoned to death by the Macedonians. The confessions indicated, it is said, that Kallisthenes, a literary man attached to the court who had been permitted, on the recommendation of his kinsman Aristotle, to accompany the expedition, not only knew of the existence of the plot, but had encouraged the pages to persist in their design. He had rendered himself obnoxious to the king by the freedom with which he expressed his opinions and by his opposition to the Persian fashions introduced into the court, and his doom was sealed. Accounts differ as to the time and mode of his death. According to Ptolemy he was tortured and then crucified, but Aristoboulos and Chares agree in stating that he was carried about in chains and died at last of disease in India.

The summer had set in when Alexander set out from Baktra on his Indian expedition. He crossed the chain of Paropamisos in ten days, and halted at the Alexandreia which he had founded at their base to settle the affairs of that city and the surrounding district. The narrative of his campaigns, from the time he left this place till he led his army into Karmania, after its disastrous march through the burning sands of the Gedrosian desert, is given in full detail in the translations which form the body of this work. His march, which on his emerging from the desert lay through the beautiful and fertile province of Karmania, resembled a festive procession, and the licence in which he permitted his soldiers to indulge was meant no less to obliterate the memory of their terrible sufferings in the desert than to celebrate according to Bacchic fashion and example the conquest of India.

In Karmania, Alexander received intelligence that Philip, who had been left in command of all the country west of the Indus had been slain in a mutiny by the Greek mercenaries under his command, but that the Macedonian troops had quelled the mutiny and put the assassins to death. He did not at the time appoint any successor to Philip, but empowered Eudêmos and Taxiles to take temporary charge of the affairs of the satrapy. Before he left Karmania he was rejoined by Krateros who brought in safety the division of the army which he had led from the Indus by way of Arachôsia, Drangiana, and the Karmanian desert. Nearchos also visited his camp, which at the time was a five days’ journey distant from the sea, and communicated the welcome news that the fleet had arrived in safety at the mouth of the Persian Gulf. The admiral was instructed to continue the voyage by sailing up the Gulf to the mouth of the Tigris, while Hephaistiôn was put in command of the main army with orders to proceed to Sousa along the maritime parts of Persis and Sousiana. The king himself with a small division took the upper road which led to that capital through Pasargadai and Persepolis. In Persis things had not gone well in his absence. The satrap whom he had appointed was dead, and his office had been usurped by Orxines, a Persian of great wealth and high rank, against whom many acts of violence and oppression were charged. He found also that the tomb of Cyrus had been desecrated and plundered, and this outrage excited his violent indignation, since he looked upon that conqueror as the founder of the vast empire which was now his own. He could not discover the perpetrators, but had to content himself with ordering the violated sepulchre to be properly restored. On reaching Persepolis he investigated the charges against Orxines, and finding them proved, put him to death, and gave his satrapy to Peukestas, one of the commanders of his bodyguard.
