Alexander himself took the command of the right, giving that of the left to Parmenion; by right and left are meant the two halves of the army, each of them including three taxeis or divisions of the phalanx with the cavalry on its flank—for there was no recognised centre under a distinct command. On the other side of the Granicus, the Persian cavalry lined the bank. The Medes and Bactrians were on their right, under Rheomithres—the Paphlagonians and Hyrcanians in the centre, under Arsites and Spithridates—on the left were Memnon and Arsamenes with their divisions. The Persian infantry, both Asiatic and Grecian, were kept back in reserve; the cavalry alone being relied upon to dispute the passage of the river.
In this array, both parties remained for some time, watching each other in anxious silence. There being no firing or smoke, as with modern armies, all the details on each side were clearly visible to the other; so that the Persians easily recognised Alexander himself on the Macedonian right from the splendour of his armour and military costume, as well as from the respectful demeanour of those around him. Their principal leaders accordingly thronged to their own left, which they reinforced with the main strength of their cavalry, in order to oppose him personally. Presently he addressed a few words of encouragement to the troops, and gave the order for advance. He directed the first attack to be made by the squadron of companion-cavalry whose turn it was on that day to take the lead (the squadrons of Apollonia, of which Socrates was captain, commanded on this day by Ptolemæus son of Philippus), supported by the light horse or Lancers, the Pæonian darters (infantry), and one division of regularly armed infantry, seemingly hypaspists. He then himself entered the river, at the head of the right half of the army, cavalry and infantry, which advanced under sound of trumpets and with the usual war-shouts. As the occasional depths of water prevented a straightforward march with one uniform line, the Macedonians slanted their course suitably to the fordable spaces; keeping their front extended so as to approach the opposite bank as much as possible in line, and not in separate columns with flanks exposed to the Persian cavalry. Not merely the right under Alexander, but also the left under Parmenion, advanced and crossed in the same movement and under the like precautions.
The foremost detachment under Ptolemy and Amyntas, on reaching the opposite bank, encountered a strenuous resistance, concentrated as it was here upon one point. They found Memnon and his sons with the best of the Persian cavalry immediately in their front; some on the summit of the bank, from whence they hurled down their javelins—others down at the water’s edge, so as to come to closer quarters. The Macedonians tried every effort to make good their landing, and push their way by main force through the Persian horse, but in vain. Having both lower ground and insecure footing, they could make no impression, but were thrust back with some loss, and retired upon the main body which Alexander was now bringing across. On his approaching the shore, the same struggle was renewed around his person with increased fervour on both sides. He was himself among the foremost, and all near him were animated by his example. The horsemen on both sides became jammed together, and the contest was one of physical force and pressure by man and horse; but the Macedonians had a great advantage in being accustomed to the use of the strong close-fighting pike, while the Persian weapon was the missile javelin. At length the resistance was surmounted, and Alexander, with those around him, gradually thrusting back the defenders, made good their way up the high bank to the level ground. At other points the resistance was not equally vigorous. The left and centre of the Macedonians, crossing at the same time on all practicable spaces along the whole line, overpowered the Persians stationed on the slope, and got up to the level ground with comparative facility. Indeed no cavalry could possibly stand on the bank to offer opposition to the phalanx with its array of long pikes, wherever this could reach the ascent in any continuous front. The easy crossing of the Macedonians at other points helped to constrain those Persians, who were contending with Alexander himself on the slope, to recede to the level ground above.
Courage and Danger of Alexander
Here again, as at the water’s edge, Alexander was foremost in personal conflict. His pike having been broken, he turned to a soldier near him—Aretis, one of the horse-guards who generally aided him in mounting his horse—and asked for another. But this man, having broken his pike also, showed the fragment to Alexander, requesting him to ask some one else; upon which the Corinthian Demaratus, one of the companion-cavalry close at hand, gave him his weapon instead. Thus armed anew, Alexander spurred his horse forward against Mithridates (son-in-law of Darius), who was bringing up a column of cavalry to attack him, but was himself considerably in advance of it. Alexander thrust his pike into the face of Mithridates, and laid him prostrate on the ground: he then turned to another of the Persian leaders, Rhœsaces, who struck him a blow on the head with his scimitar, knocked off a portion of his helmet, but did not penetrate beyond. Alexander avenged this blow by thrusting Rhœsaces through the body with his pike. Meanwhile a third Persian leader, Spithridates, was actually close behind Alexander, with hand and scimitar uplifted to cut him down. At this critical moment, Clitus son of Dropides—one of the ancient officers of Philip, high in the Macedonian service—struck with full force at the uplifted arm of Spithridates and severed it from the body, thus preserving Alexander’s life. Other leading Persians, kinsmen of Spithridates, rushed desperately on Alexander, who received many blows on his armour, and was in much danger. But the efforts of his companions near were redoubled, both to defend his person and to second his adventurous daring. It was on that point that the Persian cavalry was first broken. On the left of the Macedonian line, the Thessalian cavalry also fought with vigour and success; and the light-armed foot, intermingled with Alexander’s cavalry generally, did great damage to the enemy. The rout of the Persian cavalry, once begun, speedily became general. They fled in all directions, pursued by the Macedonians.
But Alexander and his officers soon checked this ardour of pursuit, calling back their cavalry to complete his victory. The Persian infantry, Asiatics as well as Greeks, had remained without movement or orders, looking on the cavalry battle which had just disastrously terminated. To them Alexander immediately turned his attention. He brought up his phalanx and hypaspists to attack them in front, while his cavalry assailed on all sides their unprotected flanks and rear; he himself charged with the cavalry, and had a horse killed under him. His infantry alone was more numerous than they, so that against such odds the result could hardly be doubtful. The greater part of these mercenaries, after a valiant resistance, were cut to pieces on the field. We are told that none escaped, except two thousand made prisoners, and some who remained concealed in the field among the dead bodies.
In this complete and signal defeat, the loss of the Persian cavalry was not very serious in mere number, for only one thousand of them were slain. But the slaughter of the leading Persians, who had exposed themselves with extreme bravery in the personal conflict against Alexander, was terrible. There were slain not only Mithridates, Rhœsaces, Spithridates, whose names have been already mentioned, but also Pharnaces, brother-in-law of Darius, Mithrobarzanes satrap of Cappadocia, Atizyes, Niphates, Petines, and others; all Persians of rank and consequence. Arsites, the satrap of Phrygia, whose rashness had mainly caused the rejection of Memnon’s advice, escaped from the field, but died shortly afterwards by his own hand, from anguish and humiliation. The Persian or Perso-Grecian infantry, though probably more of them individually escaped than is implied in Arrian’s account, was as a body irretrievably ruined. No force was either left in the field, or could be afterwards reassembled in Asia Minor.
The loss on the side of Alexander is said to have been very small. Twenty-five of the companion-cavalry, belonging to the division under Ptolemy and Amyntas, were slain in the first unsuccessful attempt to pass the river. Of the other cavalry, sixty in all were slain; of the infantry, thirty. This is given to us as the entire loss on the side of Alexander. It is only the number of killed; that of the wounded is not stated; but assuming it to be ten times the number of killed, the total of both together will be 1265. If this be correct, the resistance of the Persian cavalry, except near that point where Alexander himself and the Persian chiefs came into conflict, cannot have been either serious or long protracted. But when we add farther the contest with the infantry, the smallness of the total assigned for Macedonian killed and wounded will appear still more surprising. The total of the Persian infantry is stated at nearly twenty thousand, most part of them Greek mercenaries. Of these only two thousand were made prisoners; nearly all the rest (according to Arrian) were slain. Now the Greek mercenaries were well armed, and not likely to let themselves be slain with impunity; moreover Plutarch expressly affirms that they resisted with desperate valour, and that most of the Macedonian loss was incurred in the conflict against them. It is not easy therefore to comprehend how the total number of slain can be brought within the statement of Arrian.
After the victory, Alexander manifested the greatest solicitude for his wounded soldiers, whom he visited and consoled in person. Of the twenty-five companions slain, he caused brazen statues, by Lysippus, to be erected at Dium in Macedonia, where they were still standing in the time of Arrian. To the surviving relatives of all the slain he also granted immunity from taxation and from personal service. The dead bodies were honourably buried, those of the enemy as well as of his own soldiers. The two thousand Greeks in the Persian service who had become his prisoners, were put in chains, and transported to Macedonia there to work as slaves; to which treatment Alexander condemned them on the ground that they had taken arms on behalf of the foreigner against Greece, in contravention of the general vote passed by the synod at Corinth. At the same time, he sent to Athens three hundred panoplies selected from the spoil, to be dedicated to Athene in the Acropolis with this inscription, “Alexander, son of Philip, and the Greeks except the Lacedæmonians (present these offerings), out of the spoils of the foreigners inhabiting Asia.” Though the vote to which Alexander appealed represented no existing Grecian aspiration, and granted only a sanction which could not be safely refused, yet he found satisfaction in clothing his own self-aggrandising impulse under the name of a supposed Panhellenic purpose: which was at the same time useful as strengthening his hold upon the Greeks, who were the only persons competent, either as officers or soldiers, to uphold the Persian empire against him. His conquests were the extinction of genuine Hellenism, though they diffused an exterior varnish of it, and especially the Greek language, over much of the oriental world. “True Grecian interests,” says Grote, “lay more on the side of Darius than of Alexander.”
