134 HISTORICAL TALES. slaughter. The Greek loss in dead was only one hundred and ninety-two. Yet, despite this signal victory, Greece was still in imminent danger. Athens was undefended. The fleeing fleet might reach and capture it before the army could return. In truth, the ships had sailed in this direction, and from the top of a lofty hill Mil- tiades saw the polished surface of a shield flash in the sunlight, and quickly guessed what it meant. It was a signal made by some traitor to the Persian fleet. Putting his army at once under march, despite the weariness of the victors, he hastened back over the long twenty-two miles at all possible speed, and the worn-out troops reached Athens barely in time to save it from the approaching fleet. The triumph of Miltiades was complete. Only for his quickness in guessing the meaning of the flashing shield, and the rapidity of his march, all the results of his great victory would have been lost, and Athens fallen helpless into Persian arms. But Datis, finding the city amply garrisoned, and baffled at every point, turned his ships and sailed in defeat away, leaving the Athenians masters of city and field. And now the Spartans—to whom the full moon had come too late—appeared, two thousand strong, only in time to congratulate the victors and view the dead Persians on the field. They had marched the whole distance in less than three days. As for the Athenian dead, they were buried with great cere- mony on the plain where they fell, and the great mound which covers them is visible there to this day.
