The Macedonians cut their way through the mighty mass of their enemies with irresistible force. The elephants turned and fled. The foot soldiers seized the horses of some of the scythe-armed chariots and cut the traces. In respect to others, they opened to the right and left and let them pass through, when they were easily captured by the men in the rear. In the mean time the phalanx pressed on, enjoying a great advantage in the level nature of the ground. The Persian troops were broken in upon and driven away wherever they were attacked. In a word, before night the whole mighty mass was scattering every where in confusion, except some hundreds of thousands left trampled upon and dead, or else writhing upon the ground, and groaning in their dying agonies. Darius himself fled. Alexander pursued him with a troop of horse as far as Arbela, which had been Darius's head-quarters, and where he had deposited immense treasures. Darius had gone through and escaped when Alexander arrived at Arbela, but the city and the treasures fell into Alexander's hands.
