When they reached the river, they saw the Persians drawn up on the opposite bank in a long, deep line. The front of the enemy was gay with banners flaunting in the sun and resplendent with the multi-colored finery of the Persian lords. The Greeks could hear the braying of their trumpets and the shouts of their commanders as the dense masses of their cavalry wheeled into position to meet the attack. At sight of Alexander a high-pitched, long-drawn cry ran from one end of their line to the other, rising and falling in derision.
There was no answer from the Greeks. The young king drew aside to a point of vantage and threw a rapid glance at the barbarian host. He saw that the river before them broadened into a pool, over whose quiet surface the swallows were skimming. Immediately in front of him the water foamed and gurgled over a shallow, and a similar break ended the pool below. The opposite bank rose steeply from the water's edge to the wide declivity upon which the Persians had taken their stand. Behind them Memnon's mercenaries had been posted as a reserve and to be spectators of the punishment which the barbarians were to inflict upon their countrymen.
"Leonidas was right," Alexander exclaimed, pointing to the mercenaries. "See, we shall not have to meet the spears of the Greeks. Form the line, Parmenio."
Squadron and company emerged from the road and wheeled into their positions in silence under the direction of their captains. Clearchus, Chares, and Leonidas were riding with Ptolemy's troop when a page sought them and they saw Alexander beckoning.
"Do not forget that you are to fight with Alexander to-day," he said, as they rode up.
Leonidas flushed with pride and Chares threw a satisfied glance at the gorgeous breastplate which he had recovered safely. They took their places in the cluster of young Macedonians behind the king.
Amyntas, with his light horsemen, was posted on the extreme right, beyond the left of the Persian line. Ptolemy, with the heavy cavalry, stood next, and Alexander, with seven squadrons of the Companions, the best and bravest of his army, supported him on the left. Then came the terrible phalanx, rank on rank, its sarissas standing up to four times the height of a man, like a giant field of corn. Farther down the river, in the left wing, where Parmenio commanded, was the dashing Thessalian horse, with the riders of Thrace and the Greek allies, supported by other squadrons of foot-soldiers.
Quickly and calmly, as though forming for a parade, the line extended itself and stood still. Behind its centre the catapults and ballistæ were posted, with their strings tightened and their great arms drawn back, ready to hurl their bolts or to discharge their missiles.
A sudden hush fell on both sides of the river. The jeers of the Persians died away and their banners stirred lazily in the light air. The Macedonians stood facing them like an army of statues. Alexander touched his horse with the spur and rode slowly down the line alone to see that all was in readiness. As he passed he spoke to the captains, calling them by name.
"Nicanor," he said, "let your men prove themselves men once more to-day! Perdiccas, fight for the honor of Hellas! Cœnus, there are no cowards among your followers; fight now as you never fought before! Remember Macedon!"
