Remaining at Ekbatana no longer than was sufficient for these new arrangements, Alexander recommenced his pursuit of Darius. He hoped to get before Darius to the Caspian Gates, at the north-eastern extremity of Media; by which Gates[438] was understood a mountain-pass, or rather a road of many hours’ march, including several difficult passes stretching eastward along the southern side of the great range of Taurus towards Parthia. He marched with his Companion-cavalry, the light-horse, the Agrianians, and the bowmen—the greater part of the phalanx keeping up as well as it could—to Rhagæ, about fifty miles north of the Caspian Gates; which town he reached in eleven days, by exertions so severe that many men as well as horses were disabled on the road. But in spite of all speed, he learnt that Darius had already passed through the Caspian Gates. After five days of halt at Rhagæ, indispensable for his army, Alexander passed them also. A day’s march on the other side of them, he was joined by two eminent Persians, Bagistanes and Antibêlus, who informed him that Darius was already dethroned and in imminent danger of losing his life.[439]
The conspirators by whom this had been done, were Bessus, satrap of Baktria—Barsaentes, satrap of Drangiana and Arachosia—and Nabarzanes, general of the regal guards. The small force of Darius having been thinned by daily desertion, most of those who remained were the contingents of the still unconquered territories, Baktria, Arachosia, and Drangiana, under the orders of their respective satraps. The Grecian mercenaries, 1500 in number, and Artabazus, with a band under his special command, adhered inflexibly to Darius, but the soldiers of Eastern Asia followed their own satraps. Bessus and his colleagues intended to make their peace with Alexander by surrendering Darius, should Alexander pursue so vigorously as to leave them no hope of escape; but if they could obtain time to reach Baktria and Sogdiana, they resolved to organize an energetic resistance, under their own joint command, for the defence of those eastern provinces—the most warlike population of the empire.[440] Under the desperate circumstances of the case, this plan was perhaps the least unpromising that could be proposed. The chance of resisting Alexander, small as it was at the best, became absolutely nothing under the command of Darius, who had twice set the example of flight from the field of battle, betraying both his friends and his empire, even when surrounded by the full force of Persia. For brave and energetic Persians, unless they were prepared at once to submit to the invader, there was no choice but to set aside Darius; nor does it appear that the conspirators intended at first anything worse. At a village called Thara in Parthia, they bound him in chains of gold—placed him in a covered chariot surrounded by the Baktrian troops,—and thus carried him onward, retreating as fast as they could; Bessus assuming the command. Artabazus, with the Grecian mercenaries, too feeble to prevent the proceeding, quitted the army in disgust, and sought refuge among the mountains of the Tapuri bordering on Hyrkania towards the Caspian Sea.[441]
On hearing this intelligence, Alexander strained every nerve to overtake the fugitives and get possession of the person of Darius. At the head of his Companion-cavalry, his light-horse, and a body of infantry picked out for their strength and activity, he put himself in instant march, with nothing but arms and two days’ provisions for each man; leaving Kraterus to bring on the main body by easier journeys. A forced march of two nights and one day, interrupted only by a short midday repose (it was now the month of July), brought him at daybreak to the Persian camp which his informant Bagistanes had quitted. But Bessus and his troops were already beyond it, having made considerable advance in their flight; upon which Alexander, notwithstanding the exhaustion both of men and horses, pushed on with increased speed through all the night to the ensuing day at noon. He there found himself in the village where Bessus had encamped on the preceding day. Yet learning from deserters that his enemies had resolved to hasten their retreat by night marches, he despaired of overtaking them, unless he could find some shorter road. He was informed that there was another shorter, but leading through a waterless desert. Setting out by this road late in the day with his cavalry, he got over no less than forty-five miles during the night, so as to come on Bessus by complete surprise on the following morning. The Persians, marching in disorder without arms, and having no expectation of an enemy, were so panic-struck at the sudden appearance of their indefatigable conqueror, that they dispersed and fled without any attempt to resist. In this critical moment, Bessus and Barsaentes urged Darius to leave his chariot, mount his horse, and accompany them in their flight. But he refused to comply. They were determined however that he should not fall alive into the hands of Alexander, whereby his name would have been employed against them, and would have materially lessened their chance of defending the eastern provinces; they were moreover incensed by his refusal, and had contracted a feeling of hatred and contempt to which they were glad to give effect. Casting their javelins at him, they left him mortally wounded, and then pursued their flight.[442] His chariot, not distinguished by any visible mark, nor known even to the Persian soldiers themselves, was for some time not detected by the pursuers. At length a Macedonian soldier named Polystratus found him expiring, and is said to have received his last words; wherein he expressed thanks to Alexander for the kind treatment of his captive female relatives, and satisfaction that the Persian throne, lost to himself, was about to pass to so generous a conqueror. It is at least certain that he never lived to see Alexander himself.[443]
Alexander had made the prodigious and indefatigable marches of the last four days, not without destruction to many men and horses, for the express purpose of taking Darius alive. It would have been a gratification to his vanity to exhibit the Great King as a helpless captive, rescued from his own servants by the sword of his enemy, and spared to occupy some subordinate command as a token of ostentatious indulgence. Moreover, apart from such feelings, it would have been a point of real advantage to seize the person of Darius, by means of whose name Alexander would have been enabled to stifle all farther resistance in the extensive and imperfectly known regions eastward of the Caspian Gates. The satraps of these regions had now gone thither with their hands free, to kindle as much Asiatic sentiment and levy as large a force as they could, against the Macedonian conqueror; who was obliged to follow them, if he wished to complete the subjugation of the empire. We can understand therefore that Alexander was deeply mortified in deriving no result from this ruinously fatiguing march, and can the better explain that savage wrath which we shall hereafter find him manifesting against the satrap Bessus.
Alexander caused the body of Darius to be buried with full pomp and ceremonial, in the regal sepulchres of Persis. The last days of this unfortunate prince have been described with almost tragic pathos by historians; and there are few subjects in history better calculated to excite such a feeling, if we regard simply the magnitude of his fall, from the highest pitch of power and splendor to defeat, degradation, and assassination. But an impartial review will not allow us to forget that the main cause of such ruin was his own blindness—his long apathy after the battle of Issus, and abandonment of Tyre and Gaza, in the fond hope of repurchasing queens whom he had himself exposed to captivity—lastly, what is still less pardonable, his personal cowardice in both the two decisive battles deliberately brought about by himself. If we follow his conduct throughout the struggle, we shall find little of that which renders a defeated prince either respectable or interesting. Those who had the greatest reason to denounce and despise him were his friends and his countrymen, whom he possessed ample means of defending, yet threw those means away. On the other hand, no one had better grounds for indulgence towards him than his conqueror; for whom he had kept unused the countless treasures of the three capitals, and for whom he had lightened in every way the difficulties of a conquest, in itself hardly less than impracticable.[444]
The recent forced march, undertaken by Alexander for the purpose of securing Darius as a captive, had been distressing in the extreme to his soldiers, who required a certain period of repose and compensation. This was granted to them at the town of Hekatompylus in Parthia, where the whole army was again united. Besides abundant supplies from the neighboring region, the soldiers here received a donative derived from the large booty taken in the camp of Darius.[445] In the enjoyment and revelry universal throughout the army, Alexander himself partook. His indulgences in the banquet and in wine-drinking, to which he was always addicted when leisure allowed were now unusually multiplied and prolonged. Public solemnities were celebrated, together with theatrical exhibitions by artists who joined the army from Greece. But the change of most importance in Alexander’s conduct was, that he now began to feel and act manifestly as successor of Darius on the Persian throne; to disdain the comparative simplicity of Macedonian habits, and to assume the pomp, the ostentatious apparatus of luxuries, and even the dress, of a Persian king.
To many of Alexander’s soldiers, the conquest of Persia appeared to be consummated and the war finished, by the death of Darius. They were reluctant to exchange the repose and enjoyments of Hekatompylus for fresh fatigues; but Alexander, assembling the select regiments, addressed to them an emphatic appeal which revived the ardor of all.[446] His first march was, across one of the passes from the south to the north of Mount Elburz, into Hyrkania, the region bordering the south-eastern corner of the Caspian Sea. Here he found no resistance; the Hyrkanian satrap Phrataphernes, together with Nabarzanes, Artabazus, and other eminent Persians, surrendered themselves to him, and were favorably received. The Greek mercenaries, 1500 in number, who had served with Darius, but had retired when that monarch was placed under arrest by Bessus, sent envoys requesting to be allowed to surrender on capitulation. But Alexander—reproaching them with guilt for having taken service with the Persians, in contravention of the vote passed by the Hellenic synod—required them to surrender at discretion; which they expressed their readiness to do, praying that an officer might be despatched to conduct them to him in safety.[447] The Macedonian Andronikus was sent for this purpose, while Alexander undertook an expedition into the mountains of the Mardi; a name seemingly borne by several distinct tribes in parts remote from each other, but all poor and brave mountaineers. These Mardi occupied parts of the northern slope of the range of Mount Elburz a few miles from the Caspian Sea (Mazanderan and Ghilan). Alexander pursued them into all their retreats,—overcame them, when they stood on their defence, with great slaughter,—and reduced the remnant of the half-destroyed tribes to sue for peace.[448]
From this march, which had carried him in a westerly direction, he returned to Hyrkania. At the first halt he was met by the Grecian mercenaries who came to surrender themselves, as well as by various Grecian envoys from Sparta, Chalkedon, and Sinôpe, who had accompanied Darius in his flight. Alexander put the Lacedæmonians under arrest, but liberated the other envoys, considering Chalkedon and Sinôpe to have been subjects of Darius, not members of the Hellenic synod. As to the mercenaries, he made a distinction between those who had enlisted in the Persian service before the recognition of Philip as leader of Greece—and those whose enlistment had been of later date. The former he liberated at once; the latter he required to remain in his service under the command of Andronikus, on the same pay as they had hitherto received.[449] Such was the untoward conclusion of Grecian mercenary service with Persia; a system whereby the Persian monarchs, had they known how to employ it with tolerable ability, might well have maintained their empire even against such an enemy as Alexander.[450]
After fifteen days of repose and festivity at Zeudracarta, the chief town of Hyrkania, Alexander marched eastward with his united army through Parthia into Aria—the region adjoining the modern Herat with its river now known as Herirood. Satibarzanes, the satrap of Aria, came to him near the border, to a town named Susia,[451] submitted, and was allowed to retain his satrapy; while Alexander, merely skirting the northern border of Aria, marched in a direction nearly east towards Baktria against the satrap Bessus, who was reported as having proclaimed himself King of Persia. But it was discovered, after three or four days, that Satibarzanes was in league with Bessus; upon which Alexander suspended for the present his plans against Baktria, and turned by forced marches to Artakoana, the chief city of Aria.[452] His return was so unexpectedly rapid, that the Arians were overawed, and Satibarzanes was obliged to escape. A few days enabled him to crush the disaffected Arians and to await the arrival of his rear division under Kraterus. He then marched southward into the territory of the Drangi, or Drangiana (the modern Seiestan), where he found no resistance—the satrap Barsaentes having sought safety among some of the Indians.[453]
In the chief town of Drangiana occurred the revolting tragedy, of which Philotas was the first victim, and his father Parmenio the second. Parmenio, now seventy years of age, and therefore little qualified for the fatigue inseparable from the invasion of the eastern satrapies, had been left in the important post of commanding the great depôt and treasure at Ekbatana. His long military experience, and confidential position even under Philip, rendered him the second person in the Macedonian army, next to Alexander himself. His three sons were all soldiers. The youngest of them, Hektor, had been accidentally drowned in the Nile, while in the suite of Alexander in Egypt; the second, Nikanor, had commanded the hypaspists or light infantry, but had died of illness, fortunately for himself, a short time before;[454] the eldest, Philotas, occupied the high rank of general of the Companion-cavalry, in daily communication with Alexander, from whom he received personal orders.
