On a beautiful plain, twenty miles distant from the town of Arbela, the Persian monarch, surrounded by all the pomp and luxury of Eastern magnificence, had collected the remaining strength of his empire, consisting of an army of more than a million of infantry and forty thousand cavalry, besides two hundred scythed chariots, and fifteen elephants brought from the west of India. To oppose this immense force Alexander had only forty thousand infantry and seven thousand cavalry. But his forces were well armed and disciplined, and were led by an able general who had never known defeat. Darius sustained the conflict with better judgment and more courage than at Issus; but the cool intrepidity of the Macedonians was irresistible, and the field of battle soon became a scene of slaughter, in which some say forty thousand, and others three hundred thousand, of the barbarians were slain, while the loss of Alexander did not exceed five hundred men. Although Darius escaped with a portion of his body-guard, the whole of the royal baggage and treasure was captured at Arbela. Now simply a fugitive, "with merely the title of king," Darius crossed the mountains into Media, where he remained six or seven months, and until the advance of Alexander in pursuit compelled him to pass through the Caspian Gates into Parthia. Here, on the near approach of the enemy, he was murdered by Bessus, satrap of Bactria, because he refused to fly farther. "Within four years and three months from the time Alexander crossed the Hellespont," says GROTE, "by one stupendous defeat after another Darius had lost all his Western empire, and had become a fugitive eastward of the Caspian Gates, escaping captivity at the hand of Alexander only to perish by that of the satrap Bessus. All antecedent historical parallels--the ruin and captivity of the Lydian Croe'sus, the expulsion and mean life of the Syracusan Dionysius, both of them impressive examples of the mutability of human condition--sink into trifles compared with the overthrow of this towering Persian colossus. The orator Æschines expressed the genuine sentiment of a Grecian spectator when he exclaimed (in a speech delivered at Athens shortly before the death of Darius): "'What is there among the list of strange and unexpected events which has not occurred in our time? Our lives have transcended the limits of humanity; we are born to serve as a theme for incredible tales to posterity. Is not the Persian king--who dug through Athos and bridged the Hellespont, who demanded earth and water from the Greeks, who dared to proclaim himself, in public epistles, master of all mankind from the rising to the setting sun--is not he now struggling to the last, not for dominion over others, but for the safety of his own person?' [Footnote: He speaks of both Xerxes and Darius as the Persian king.] Such were the sentiments excited by Alexander's career even in the middle of 330 B.C., more than seven years before his death."
