In the history of Rome there is a story which tells how King Tarquin desired, once upon a time, to conquer the town of Gabii. As he was unable to overcome it by fair fighting, he determined to have recourse to treachery, and in order to carry out his purpose, sent his son to the city. The son knocked at the city gate, and when from within they asked who was there, he said that he was the son of Tarquin, but that he came as a friend, not an enemy, for his father had ill-treated him shamefully, and he wished now to revenge himself by helping the Gabians to defend their city. The townsmen let him in, and after having seen him, time after time, fighting bravely in their ranks, they gave him their full confidence, and finally chose him to be their general-in-chief. So far he had succeeded, but he did not know what was the next thing to be done, and therefore sent a trusted slave to ask his father’s advice. The king took the slave into his garden, where there was a bed of poppies in full bloom, and walking up and down beside the bed, he struck off the heads of the tallest poppies, one by one. Then he said to the slave, ‘Go back and tell my son what you have seen.’ The slave did not know how this could be an answer to the question that had been asked, but when he had carefully described to his master what he had seen, the son understood very well what it meant. One after another, he impeached in turn all the chief men of the city upon some frivolous pretext or other, and he did it so cleverly that their fellow-townsmen believed them to be traitors, and condemned them either to death or banishment. When the city had been deprived of all its best men, it was easy enough for him to give it up into the hands of his father. In like manner Tissaphernes thought that by the removal of their officers, the Hellenes would be left helpless, and would no longer have the heart to fight for their lives and their freedom. But it fell out otherwise, for the officers who had been betrayed by Tissaphernes were succeeded by others still more able. Above all, Xenophon the Athenian, a man hitherto almost unnoticed in the crowd, came forward, and by his inspiring presence, his sound judgment, and his unfailing courage, gained the confidence of his comrades, and brought them at last through all their difficulties to a place of safety.
