The Athenians put forth almost superhuman efforts to retrieve their fortunes. Had they been united among themselves, perhaps their efforts might not have been in vain. But the oligarchical party, for the sake of ruining the democracy were willing to ruin the empire. While the army was absent from Athens, they overturned the government, and established a sort of aristocratical rule (411 B.C.), under which affairs were in the hands of a council of Four Hundred. The Athenian troops, however, who were at Samos, would not recognize the new government. They voted themselves to be the true Athens, and forgetting and forgiving the past, recalled Alcibiades, and gave him command of the army, thereby well illustrating what the poet Aristophanes said respecting the disposition of the Athenians towards the spoiled favorite,--"They love, they hate, but cannot live without him." Alcibiades detached the Persians from the side of the Spartans, and gained some splendid victories for Athens. But he could not undo the evil he had done. He had ruined Athens beyond redemption by any human power. Constantly the struggle grew more and more hopeless. Alcibiades was defeated, and fearing to face the Athenians, who had deposed him from his command, sought safety in flight. Finally, at Ægospotami, on the Hellespont, the Athenian fleet was surprised and captured by the Spartans under Lysander (405 B.C.). The prisoners, three thousand in number, were massacred, and the usual rites of burial denied their bodies. The battle of Ægospotami sealed the fate of Athens. "That night," writes the historian Xenophon, referring to the night upon which the news of the woful disaster reached Athens, "That night no man slept." The towns on the Thracian and Macedonian coasts, and the islands of the Ægean belonging to the Athenian Empire, now fell into the hands of the Peloponnesians. Athens was besieged by sea and land, and soon forced to surrender. Some of the allies insisted upon the total destruction of the city, and the conversion of its site into pasture-land. The Spartans, however, with apparent magnanimity, declared that they would never consent thus "to put out one of the eyes of Greece." The real motive, doubtless, of the Spartans in sparing the city was their fear lest, with Athens blotted out, Thebes or Corinth should become too powerful. So the city itself was spared, but the fortifications of Piræus and the Long Walls were levelled to the ground, the work of demolition being begun to the accompaniment of festive music (404 B.C.). Sparta's power was now supreme. She had neither peer nor rival among all the Grecian states. Throughout the war she had maintained that her only purpose in warring against Athens was to regain liberty for the Grecian cities. We shall very soon see what sort of liberty it was that they enjoyed under her guardianship.
