The Battle of Issus.

Yet the Persians had a still unbroken strength with which much might have been done, if only there had been a leader to make use of it. The Greeks in the centre stood their ground bravely. They even advanced, charged the left divisions of the phalanx, which had not completed the passage of the Pinarus, and inflicted some loss upon it, killing as many as 150 of the front rank men, and the officer in command. But by themselves they could not hope to hold the field. When Alexander, wheeling round after his victorious assault on the Persian right, attacked them in flank, they were forced to give way. But they retired in good order, and the main body of them made good their escape. The Persian cavalry, too, had shown themselves not altogether unworthy of their ancient renown. They had actually crossed the Pinarus, and charged the Thessalian horse, which had been transferred, it should be said, by Alexander from the right to the left of his army. In the combat that ensued they held their own. But their courage failed when they became aware of the flight of Darius. When their king had given up the struggle what was there for them to stay for? To him they were bound, but they had no conception of a country to whose service it was their duty to devote their lives. They fled, suffering greatly in the pursuit.

The Macedonians lost 450 in killed, Alexander himself being slightly wounded. The slaughter among the Persians cannot be estimated. It was put down at more than 100,000. Ptolemy, afterwards King of Egypt, who was one of Alexander's most trusted generals, declared that he found a ravine so choked with dead bodies that he could use them as a bridge. Ptolemy kept a diary of the war, which he afterwards embodied in a regular narrative. Arrian, who wrote the story of Alexander's campaign in the second century of our era, had this work before him.

THE ARMY OF THE HUNDRED PROVINCES

During the twenty months which followed the victory of Issus, Alexander continued to make fresh conquests and to consolidate those already made. He subdued Syria—a name which must be taken to include both Phœnicia and Palestine. Here the two cities of Tyre and Gaza made an obstinate resistance, the two detaining him for no less than nine months. Egypt, which hated its intolerant Persian masters, gave itself up without a struggle. Early in 331 he heard that Darius had collected another huge army, with which to make another effort for his kingdom. The king had lost the western half of his dominions, but the eastern still remained to him, and from this he drew forces which exceeded in number even the great host which he had put into the field at Issus. The meeting-place was at Arbela, a place still known by the slightly changed name of Erbil, and situated on the caravan-route between Erzeroum and Bagdad; but the actual battlefield must be looked for some twenty miles away in a level region known by the name of Gaugamela.

On the extreme right were the Medes, once the ruling people of Asia and still mindful of their old renown, the Parthian cavalry, and the sturdy mountaineers of the Caucasus; on the opposite wing were the Bactrians—mostly hardy dwellers in the hills, and famous both for activity and for fierceness—and the native Persians, horse and foot, in alternate formation. But it was in the centre of the line, round the person of Darius, where he stood conspicuous on his royal chariot, that the choicest troops of the Empire were congregated. Here were ranged the Persian Horseguards—a force levied from the noblest families of the race that had ruled Western Asia for more than two centuries. They were known by the proud title of "Kinsmen of the King," and the Footguards, also a corps d'élite, who carried apples at the butt-end of their pikes. Next to these stood the Carians, probably a colony from the well-known people of that name in Asia Minor, possibly transported by some Persian king to a settlement in the East. Of all Asiatic races the Carians had shown themselves the most apt to learn the Greek discipline and to rival Greek valour. Next to the Carians, again, stood the Greek mercenaries.

In front of the line were the scythed chariots, numbering two hundred in all, each with its sharp-pointed sides projecting far beyond the horses, and its sword-blades and scythes stretching from the yoke and from the naves of the wheels. (This is the first time that we hear of the scythed chariot. It was a device of a barbarian kind, and seldom, as far as we know, very effective.) Behind the line, again, was a large mixed multitude, drawn from every tribe that still owned the Great King's sway.
