Escape of Darius into Media.—March of Alexander to Babylon and Susa. Immediately after the battle, Darius marched through the mountains of Armenia towards Media, accompanied in his flight by the Bactrian cavalry, as they had then been posted with him in the battle; also by those Persians who were called the king’s kinsmen, and by 171a few of the men called apple-bearers.428 About 2,000 of his Grecian mercenaries also accompanied him in his flight, under the command of Paron the Phocian, and Glaucus the Aetolian.
