It was about an hour from sunset when Alexander, who was riding in advance with a small staff, came in sight of the Persian army. It was, indeed, but a single mile distant; and through the clear air, unencumbered by the smoke of modern artillery, every detail of its formation could be distinctly seen. The bank was lined with cavalry. On the right were the Medes and Bactrians, wearing the round-topped cap, the gaily-coloured tunic, and the scale armour which were distinguishing parts of their national dress; the Paphlagonians and Hyrcanians, equipped in much the same way, occupied the centre. Memnon the Rhodian, the ablest of the counsellors of Darius, of whom we shall hear more hereafter, shared with a Persian satrap the command of the right. He had a few Greek troopers with him, but most of his men were Asiatics. These were, however, the best horsemen that the vast empire of Darius could send into the field. The descendants of the Seven Deliverers,19 with the flower of the Persian youth, in all the pride of a caste that claimed to rule more than a hundred provinces, stood in all the splendour of their gilded arms, to dispute the passage of the river. The stream, greatly diminished indeed from its volume in early spring, when it is swollen by the melting snows of Mount Ida, but not yet dwindled to the slender proportions of summer,20 was flowing with considerable volume. The ford was many hundred yards in length, and for all this distance the right bank opened out into level ground. The whole of this was occupied by the cavalry. On the rising ground behind, marking the extreme limit reached by the floods of water, or, rather, of early spring, the infantry, both Greek and Asiatic, were posted in reserve. Mounted on his famous steed Bucephalus, the king rode along the line, addressing a few words of encouragement to each squadron and company as he passed it, and finally placed himself at the head of the right division of the army. (There were, it should be remembered, but two divisions.) For some minutes the two armies stood watching each other in silence. Then, as the Persian leaders recognized the presence of Alexander on the right wing of his own force—and it was easy to distinguish him by his gilded arms, his splendid charger, and the movement of the line as he rode along it—they began to reinforce their own left. The fame of his personal prowess had not failed to reach them; and they knew that the fiercest struggle would be where he might be in immediate command. Alexander saw the movement, and it hastened his own action. If he could catch his antagonists in the confusion of a change he would have them at a disadvantage. The word to advance was given, and the whole army moved forward towards the river, the right wing being somewhat in advance. Here was the famous corps d’élite, a heavy cavalry regiment that went under the name of the “Royal Companions.” This was the first to enter the river. A number of javelin-throwers and archers covered them on either flank; and they were followed by some light horse, and by one of the regiments of light infantry. This happened to be Charidemus’s own; he had begged and obtained permission to return to his place in its ranks.
The van of the attacking force made its way in fair order through the stream. The bottom was rough and uneven, full of large stones brought down by winter floods, with now and then a hole of some depth, but there was no mud or treacherous sand. The first onset on the defenders of the further bank was not successful. A line of dismounted troopers stood actually in the water, wherever it was shallow enough to allow it; on the bank above them (the summer bank, as it may be called, in distinction from that mentioned before as the limit of the winter floods) was ranged a dense line of horsemen, two or three files deep. The combatants below plied their swords, or thrust with their short spears; those above them showered their javelins upon the advancing enemy, and these, not only finding their footing insecure, but having to struggle up a somewhat steep ascent, failed to get any permanent hold on the coveted bank. The few who contrived to make their way up were either slain or disabled, and the rest were thrust back upon the troops that followed them. These were of course checked in their advance, and it was not till the king himself at the head of the main body of his army took up the attack that there appeared a prospect of success. Then indeed the tide of battle began to turn. For the first of many times throughout these marvellous campaigns the personal strength, the courage, the dexterity in arms of Alexander, a matchless soldier as well as a matchless general, changed the fortune of the day. He sprang forward, rallying after him his disheartened troops, struck down adversary after adversary, and climbed the bank with an agility as well as a daring which seemed to inspire his companions with an irresistible courage. What a few minutes before had seemed impossible was done; the first bank of the Granīcus was gained. But the battle was not yet won. The Persians had been beaten back from their first line of defence, but they still held the greater part of the level ground in what seemed overwhelming force. And now they could deliver charges which with the superior weight of horses and men might be expected to overthrow a far less numerous foe. Again Alexander was in the very front of the conflict. His pike had been broken in the struggle for the bank. He called to one of the body-guards, a man whose special office it was to hold his horse when he mounted or dismounted, and asked for another. The man, without speaking, showed him his own broken weapon. Then the king looked round on his followers, holding high the splintered shaft. The appeal was answered in an instant. This time it was a Greek, Demaratus of Corinth, who answered his call, and supplied him with a fresh lance. It was not a moment too soon. A heavy column of Persian horse was advancing against him, its leader, Mithradates, son-in-law of Darius, riding a long way in advance of his men. Alexander spurred his horse, charged at Mithradates with levelled pike, struck him on the face, and hurled him dying to the ground. Meanwhile another Persian noble had come up. He struck a fierce blow at the king with his scymetar, but in his excitement almost missed his aim, doing no further damage than shearing off the crest of the helmet. Alexander replied with a thrust which broke through his breastplate, and inflicted a mortal wound. There was a third antagonist behind, but his arm was severed by a sword-cut from a Macedonian officer just as it was in the act of delivering a blow. The mêlée however, still continued with unabated fury. The Persian nobles pressed forward with a reckless courage; and it was not till almost every leader had fallen that the cavalry gave way.
In other parts of the field the resistance had been less obstinate. The élite of the Persian army had been brought together to oppose Alexander, and the remainder did not hold their ground with the same tenacity. When the phalanx, after meeting no opposition in making the passage of the river, formed again on the other shore, and made its way over the level ground, it encountered no resistance. All the defending force either had perished or was scattered in a wild flight over the plain.
A force, however, still remained unbroken, which, had it been properly handled, might have been found a serious difficulty for the conquerors. The infantry had remained, during the conflict just described, in absolute inaction on the rising ground, watching without attempting to share in the battle that was being fought on the plain below. They had no responsible leader; no orders had been issued to them. The Persian nobles had felt, in fact, so blind a confidence in the strength of their own special arm, the cavalry, that they had treated this important part of their resources with absolute neglect. And yet, not to speak of the native troops, there were not less than ten thousand Greek mercenaries,
