All would have been well, had not one man slipped and knocked a tile off the top of the wall. It rattled and fell to the ground with a noise that roused the Spartans, who scrambled up the wall in great haste. But the darkness was so dense that they could see nothing. Those of the garrison who had stayed in the city did all that they could to perplex the enemy, by making a sally on the side of the town farthest from that by which their friends had fled. And when the Spartans lit torches and flashed danger signals to the Thebans whose city was not far off, the Plataeans lit beacons, so that the signals were confused. Meanwhile the fugitives, having reached the ground in safety, were met by a band of three hundred Spartans. These were carrying lights, so the Plataeans were able to send a shower of arrows among them with sure and deadly aim. In the confusion that followed, all save one archer succeeded in crossing a ditch, covered with ice, but too thin to bear the weight of the fugitives. They struggled through the icy water, and after many narrow escapes two hundred and twelve weary men reached Athens in safety. Plataea held out gallantly until the summer of 427 B.C., when famine at length forced her to surrender. Five judges were sent from Sparta to decide the fate of the prisoners. But the trial was a mere form, for the Thebans had already persuaded the Spartans how to treat the unfortunate men. Each prisoner as he was brought before the judges was asked if he had helped the Spartans in their war against Athens. As each one answered ‘No,’ he was led out and put to death. In this way two hundred Plataeans and twenty-five Athenians lost their lives, while the city they had so bravely defended was razed to the ground. CHAPTER LXIV THE SENTENCE OF DEATH In the fourth year of the Peloponnesian War the city of Mytilene threw off the yoke of Athens. Mytilene was the capital of Lesbos, an island near the coast of Asia. The city had belonged to the Delian league, and when the league became the empire of Athens, the city remained faithful to the empire. But as time passed the Mytileneans became afraid lest Athens should treat them as she had treated the Samians, and should make them subjects instead of allies. While Athens was at war with Sparta she would have little time, thought the Mytileneans, to trouble about their small island, so they revolted and asked the Spartans to support them, if that should be necessary. The Spartans promised to help the Mytileneans if the Athenians should punish their disloyalty, but, as so often happened, they did not attempt to keep their promise until it was too late. Athens was angry when she heard of the revolt at Mytilene. Although she could ill spare the men, she sent an army under a general named Paches to blockade the town by sea and by land and so to starve her into submission. At all costs Mytilene must not fall into the hands of Sparta.
