At Megara this year the dissensions of the oligarchical and popular factions almost resulted in its capture by the Athenians. The Lacedæmonian Brasidas, however--who had distinguished himself at Pylos--effected an entry, so that the oligarchical and Peloponnesian party became permanently established in power. The most important operations were now in two fields. Brasidas made a dash through Thessaly into Macedonia, in alliance with Perdiccas of Macedon, with the hope of stirring the cities of Chalcidice to throw off the Athenian yoke; and the democrats of Boeotia intrigued with Athens to assist in a general revolution. Owing partly to misunderstandings and partly to treachery, the Boeotian democrats failed to carry out their programme, the Athenians were defeated at Delium, and Delium itself was captured by the Boeotians. Meanwhile, Brasidas succeeded in persuading Acanthus to revolt, he himself winning the highest of reputations for justice and moderation as well as for military skill. Later in the year he suddenly turned his forces against the Athenian colony of Amphipolis, which he induced to surrender by offering very favourable terms before Thucydides, who was in command of Thasos, arrived to relieve it. The further successes of Brasidas during this winter made the Athenians ready to treat for peace, and a truce was agreed upon for twelve months. Brasidas, however, continued to render aid to the subject cities which revolted from Athens--this being now the ninth year of the war--but he failed in an attempt to capture Potidæa. The period of truce terminating without any definite peace being arrived at, the summer of the tenth year is chiefly notable for the expedition sent under Cleon to recover Amphipolis, and for a recrudescence of the old quarrel in Sicily between Leontini and Syracuse. Before Amphipolis, the incompetent Cleon was routed by the skill of Brasidas; but the victor as well as the vanquished was slain, though he lived long enough to know of the victory. Their deaths removed two of the most zealous opponents of the peace for which both sides were now anxious. Hence at the close of the tenth year a definite peace was concluded. The Lacedæmonians, however, were almost alone in being fully satisfied by the terms, and the war was really continued by an anti-Laconian confederation of the former Peloponnesian allies, who saw in the peace a means to the excessive preponderance of Athens and Sparta. Argos was brought into the new confederacy in the hope of establishing her nominal equality with Sparta. For some years from this point the combinations of the states were constantly changing, while Athens and Sparta remained generally on terms of friendliness, the two prominent figures at Athens being the conservative Nicias and the restless and ambitious young intriguer Alcibiades.
