We have told in an earlier tale how Sparta and Thebes captured Plataea and swept it from the face of the earth. Recently Sparta had rebuilt the city, recalled its exiled citizens, and placed it as a Spartan outpost against Thebes. But now, when the armies of Sparta had withdrawn, the Thebans deemed it a good opportunity to conquer it again. One day, when the Plataean men were at work in their fields, and unbroken peace prevailed, a Theban force suddenly took the city by surprise, and forced the Plataeans to surrender at discretion. Poor Plataea was again levelled with the ground, her people were once more sent into exile, and her soil was added to that of Thebes. It may be well to say here that most of the Grecian cities consisted of the walled town and sufficient surrounding land to raise food for the inhabitants within, and that the farmers went out each morning to cultivate their fields, and returned each night within the shelter of their walls. It was this habit that gave Thebes its treacherous opportunity. During the seven years mentioned we hear nothing of Epaminondas, yet we know that he made himself felt within the walls of Thebes; for when, in 371 B.C., the cities of Greece, satisfied that it was high time to stop cutting each other's throats, held a congress at Sparta to conclude peace, we find him there as the representative of Thebes. The terms of peace demanded by Athens, and agreed to by most of the delegates, were that each city, small or large, should possess autonomy, or self-government. Sparta and Athens were to become mutual guarantees, dividing the headship of Greece between them. As for Thebes and her claim to the headship of Boeotia, her demand was set aside. This conclusion reached, the cities one after another took oath to keep the terms of peace, each city swearing for itself except Sparta, which took the oath for itself and its allies. When it came to the turn of Thebes there was a break in this love-feast. Sparta had sworn for all the cities of Laconia; Epaminondas, as the representative of Thebes, insisted on swearing not for Thebes alone, but for Thebes as president of all Boeotia. He made a vigorous speech, asking why Sparta was granted rights from which other leading cities were debarred. This was a new question. No Greek had ever asked it openly before. To Sparta it seemed the extreme of insolence and insult. What daring stranger was this who presumed to question her right to absolute control of Laconia? No speech was made in her defence. Spartans never made speeches. They prided themselves on their few words and quick deeds,--_laconic_ utterances, as they have since been called. The Spartan king sprang indignantly from his seat. "Speak plainly," he scornfully demanded. "Will you, or will you not, leave to each of the Boeotian cities its separate autonomy?" "Will _you_ leave each of the Laconian towns its separate autonomy?" demanded Epaminondas.
