Into the living wall the Macedonians hewed their way, foot by foot. Alexander raged like a tiger, knowing that here the battle was to be lost or won. The phalanx was all but broken. Away on the beach the Thessalians had been borne back by the impenetrable masses of the Persian cavalry and were holding the enemy in check only by a series of desperate and reckless charges. At that moment Darius was triumphant everywhere excepting at the bloody curve in the river where Alexander led in person.
It seemed to Clearchus that for hours they were locked in that desperate struggle without being able to advance. His lance was broken and the hand in which he held his sword was numb. Beside him he saw the broad shoulders of Chares heave and fall as he delivered his blows. The lust of battle seemed to flame in the Theban's veins like a fever. Again and again the mercenaries leaped upon him to pull him down. His sword was everywhere.
"He is mad!" thought Clearchus, and so indeed he seemed.
Nathan fought beside him, cool and wary, parrying and thrusting with sinews of steel. His eyes glowed with excitement held in check, and a flush tinged the sunburned olive of his cheek.
Little by little, the Companions worked their way toward the hypaspists, until at last the cavalry and the foot fought side by side, with Alexander at their head. So fierce was the conflict that flesh and blood could not long sustain it. The flank attack finally threw the left of the mercenaries into confusion, which gradually extended until the ranks that opposed the phalanx began to waver. A mighty quiver ran through the hireling force. Its resistance weakened and it gave ground.
With a wild shout the phalanx rushed up the river bank. The mercenary lines were hurled backward. The wall was broken.
Among the swirling eddies of men and plunging horses, Clearchus found himself close to Alexander. He saw the young king, sword in hand, his armor dimmed with dust and blood, pause for a moment with heaving breast to note the final charge of the phalanx. As soon as he saw the straightened lines and caught sight of the sarissas rising above the river bank, followed by the grim faces of his veterans, he turned and directed his gaze in the opposite direction, toward Darius.
The Great King had not shifted his ground since the beginning of the battle. He still stood, erect and proud, in the golden chariot with its four white steeds, whose jewelled bridles were held by slaves. His long robe, in folds of lustrous purple, floated from his shoulders. In his hand he held an idle bow, inlaid with pearl. He looked unmoved upon the slaughter that was going on before his eyes, but when the mercenary line gave way, he turned to his brother Oxathres.
"Is that the courage of which these Greeks boast so much?" he asked.
Oxathres shrugged his shoulders.
