175. At the beginning of the eighth year the Athenians were every-where triumphant, and the Spartans, humbled and distressed, had repeatedly asked for peace. Nicias, in the early part of the year, conquered the island of Cythera, and placed garrisons in its two chief towns, which were a continual defiance of the Lacedæmonians. He then ravaged the coasts of Laconia, and captured, among other places, the town of Thyr´ea, where the Æginetans, after their expulsion from their own island, had been permitted to settle. Those of the original exiles who survived were carried to Athens and put to death. The brutalizing influences of war were more apparent every year, and these cold-blooded massacres had become almost of common occurrence.
The Spartans, about the same time, alarmed by the nearness of the Messenian garrisons of Pylos and Cythera, gave notice that those Helots who had distinguished themselves by their faithful services during the war, should be set at liberty. A large number of the bravest and ablest appeared to claim the promise. Two thousand of these were selected as worthy of emancipation, crowned with garlands, and dignified with high religious honors. But in a few days they had all disappeared, by means known only to the Spartan ephors—men unmoved, either by honor or pity, from their narrow regard to the supposed interest of the state.

176. The success of the Athenians did not entirely desert them in their Megarian expedition, but their attempt upon Bœotia resulted only in disaster. The chief movement was executed by Hippoc´rates, who led an army of more than 32,000 soldiers across the Bœotian frontier to Delium, a place strongly situated near Tanagra, among the cliffs of the eastern coast. Here he fortified the temple of Apollo, and placing a garrison in the works, set out for home. The Bœotians had collected a large army at Tanagra, which now moved to intercept the Athenians upon the heights of Delium. The battle commenced late in the day. The Athenian right was at first successful, but their left was borne down by the Theban phalanx. In their ranks were Socrates, the philosopher, and his pupils, Alcibi´ades and Xenophon, all destined to the highest fame in Grecian history. At length the Bœotian cavalry appeared, and decided the fortunes of the day. The Athenians fled in all directions, and only the fall of night prevented their complete destruction. Delium was taken by siege after seventeen days.
177. Soon after these disasters, the Athenians lost all their dominion in Thrace. Brasidas had led a small but well chosen army to the aid of Perdiccas and the Chalcidian towns. The bravery and integrity of this great general led many of the allies of Athens to forsake her party, and when he suddenly appeared before Amphipolis, that city surrendered with scarcely an attempt at resistance. Thucydides,[51] the historian, was general in that region. The Athenian party in Amphipolis sent to him for aid, but he arrived too late. For this failure, whether proceeding from necessity or carelessness, the general was sentenced to banishment, and spent his next twenty years in exile, during which he contributed more by his literary work to the glory of Greece, than he would probably have done in military command. Brasidas proceeded to the easternmost of the three Chalcidian peninsulas, and received the submission of nearly all the towns.
The Athenians were now so disheartened by their losses, that they, in turn, began to propose peace; and the Spartans, anxious for the return of their noble youths who were prisoners in Athens, were equally desirous of a treaty. To this end a year’s truce was agreed upon, in 423, to afford time for permanent negotiations. Unhappily, two days after the beginning of the truce, Scio´ne revolted from the Athenians, who demanded its restitution. The Spartans refused, and the whole year was suffered to pass away without any further efforts toward peace. At its expiration, Cleon advanced into Thrace with a fleet and army. He took the towns of Toro´ne and Galepsus, and was proceeding against Amphipolis, when a battle ensued which ended at once his life and his assumption of power. Brasidas, too, was mortally wounded, but he lived long enough to know that he was victorious.
178. Peace of Nicias. The two great obstacles to peace were now removed, and, in the spring of 421, a treaty for fifty years, commonly called the “Peace of Nicias,” was concluded between Athens and Sparta. Some allies of the latter complained that Sparta had sacrificed their interests to her own, and formed a new league, with Argos for their head. Athens made a new alliance for a hundred years with Argos, Elis, and Mantine´a, B. C. 420.
