Athens never recovered from this terrible blow. The Spartans quickly renewed the contest, now with the highest hopes of success. The Athenians had to guard their city against the invader night and day; their slaves deserted to the enemy; and they themselves could do no farming except under the walls of the city. For supplies they had to depend entirely on their ships. For nearly ten years, however, the Athenians kept up the struggle. At length the Spartans captured an Athenian fleet near Aegospotami on the Hellespont. Soon afterwards they blockaded Piraeus and their army encamped before the walls of Athens. Bitter famine compelled the Athenians to sue for peace. The Spartans imposed harsh terms. The Athenians were obliged to destroy their Long Walls and the fortifications of Piraeus, to surrender all but twelve of their warships, and to acknowledge the supremacy of Sparta. 37. THE SPARTAN AND THEBAN SUPREMACIES, 404-362 B.C. SPARTAN DESPOTISM Sparta was now the undisputed leader of Continental Greece and of the Aegean. As the representative of the liberty-loving Greeks she had humbled the pride and power of "tyrant" Athens. A great opportunity lay before her to reorganize the Hellenic world and to end the struggles for supremacy between rival cities. But Sparta entered upon no such glorious career. She had always stood as the champion of aristocracy against democracy, and now in her hour of triumph she began to overturn every democratic government that still existed in Greece. The Greek cities soon found they had exchanged the mild sway of Athens for the brutal despotism of Sparta. THE FREEING OF THEBES 379 B.C. But Spartan despotism provoked resistance. It was the Boeotian city of Thebes which raised the standard of revolt. Some of the liberty-loving Thebans, headed by Pelopidas, a patriotic noble, formed a conspiracy to drive the Spartans out of the city. Disguised as huntsmen, Pelopidas and his followers entered Thebes at nightfall, killed the tyrants whom Sparta had set over the people, and forced the Spartan garrison to surrender. BATTLE OF LEUCTRA, 371 B.C. The Thebans had now recovered their independence. Eight years later they totally defeated a superior Peloponnesian force at the battle of Leuctra and brought the supremacy of Sparta to an end. This engagement from a military standpoint is one of the most interesting in ancient history. Epaminondas, the skilful Theban commander, massed his best troops in a solid column, fifty men deep, and hurled it with terrific force against the Spartan ranks. The enemy, drawn up twelve men deep in the customary formation, could not withstand the impact of the Theban column; their lines gave way, and the fight was soon won. The battle destroyed once for all the legend of Spartan invincibility. PELOPIDAS AND EPAMINONDAS
