These men now saw that their only chance of safety was to cut their way through; and in one huge column they charged desperately upon the Macedonians. There was here a close hand-to-hand fight, which lasted some time, and sixty of the royal horse-guards fell, and three generals, who fought close to Alexander's side, were wounded. At length the Macedonian, discipline and valour again prevailed, and a large number of the Persian and Indian horsemen were cut down; some few only succeeded in breaking through and riding away. Relieved of these obstinate enemies, Alexander again formed his horse-guards, and led them towards Parmenio; but by this time that general also was victorious. Probably the news of Darius's flight had reached Mazaeus, and had damped the ardour of the Persian right wing; while the tidings of their comrades' success must have proportionally encouraged the Macedonian forces under Parmenio. His Thessalian cavalry particularly distinguished themselves by their gallantry and persevering good conduct; and by the time that Alexander had ridden up to Parmenio, the whole Persian army was in full flight from the field. It was of the deepest importance to Alexander to secure the person of Darius, and he now urged on the pursuit. The river Lycus was between the field of battle and the city of Arbela, whither the fugitives directed their course, and the passage of this river was even more destructive to the Persians than the swords and spears of the Macedonians had been in the engagement. [I purposely omit any statement of the loss in the battle. There is a palpable error of the transcribers in the numbers which we find in our present manuscripts of Arrian; and Curtius is of no authority.] The narrow bridge was soon choked up by the flying thousands who rushed towards it, and vast numbers of the Persians threw themselves, or were hurried by others, into the rapid stream, and perished in its waters. Darius had crossed it, and had ridden on through Arbela without halting. Alexander reached that city on the next day, and made himself master of all Darius's treasure and stores; but the Persian king unfortunately for himself, had fled too fast for his conqueror: he had only escaped to perish by the treachery of his Bactrian satrap, Bessus.
