THE RETREAT OF THE TEN THOUSAND. We have now to tell of one of the most remark- able events in Grecian history, to describe how ten thousand Greeks, who found themselves in the heart of the great Persian empire, without a leader and almost without food, marched through the land of their foes, over rugged mountains swarming with enemies, and across lofty plains covered deep with snow, until finally they reached once more their native land. Xenophon, their chosen leader, has told the story of this wonderful march in a book called the “ Anabasis,” and from. this book we take what we have here to say. First, how came these Greeks so far away from their home and friends? We have told elsewhere how the Persians several times invaded Greece, We have now to tell how the Greeks first invaded Persia. It happened many years afterwards. The Persian king Xerxes had long since been dead, and succeeded by his son Artaxerxes, who reigned over Persia for nearly forty years. Then came Darius Nothus, whose reign lasted nineteen years, This king had two sons, Artaxerxes and Cyrus. On his death he bequeathed the throne to Artaxerxes, while Cyrus was left satrap of a large province in Asia Minor. 231
