It lay before them without a wall or tower. Through its whole history no foreign army had come so near it. It trusted for defence not to walls, but to Spartan hearts and hands. Yet now consternation reigned. Sparta the inviolate, Sparta the unassailable, was in imminent peril of suffering the same fate it had often meted out freely to its foes.
But the Spartans had not been idle. Allies had sent aid in all haste to the city. Even six thousand of the Helots were armed as hoplites, though to see such a body of their slaves in heavy armor alarmed the Spartans almost as much as to behold their foes so near at hand. In fact, many of the Helots and country people joined the Theban army, while others refused to come to the aid of the imperilled city.
Epaminondas marched on until he was in sight of the city. He did not attempt to storm it. Though without walls, Sparta had strong natural defences, and heaps of earth and stones had been hastily thrown up on the most open roads. A strong army had been gathered. The Spartans would fight to death for their homes. To attack them in their stronghold might be to lose all that had been gained. Repulse here would be ruin. Content with having faced the lion in his den, Epaminondas turned and marched down the Eurotas, his army wasting, plundering, and burning as it went, while the Spartans, though in an agony of shame and wounded honor, were held back by their king from the peril of meeting their enemy in the field.
In the end, his supplies growing scarce, his soldiers loaded with plunder, Epaminondas led his army back to Arcadia, having accomplished far more than any foe of Sparta had ever done before, and destroyed the warlike reputation of Sparta throughout Greece.
But the great Theban did not end here. He had two other important objects in view. One was to consolidate the Arcadians by building them a great central city, to be called Megalopolis (Great City), and inhabited by people from all parts of the state. This was done, thick and lofty walls, more than five miles and a half in circumference, being built round the new stronghold.
His other purpose was to restore the country of Messenia. We have already told how this country had been conquered by the Spartans centuries before, and its people exiled or enslaved. Their descendants were now to regain their liberty and their homes. A new city, to be named Messenia, was ordered by Epaminondas to be built, and this, at the request of the Messenians, was erected on Mount Ithome, where the gallant hero Aristomenes had made his last stand against his country's invaders.
The city was built, the walls rising to the music of Argeian and Bœotian flutes. The best architects and masons of Greece were invited to lay out the plans of streets and houses and of the sacred edifices. The walls were made so strong and solid that they became the admiration of after-ages. The surrounding people, who had been slaves of Sparta, were made freemen and citizens of the reorganized state. A wide area of land was taken from Laconia and given to the new communities which Epaminondas had formed. Then, in triumph, he marched back to Thebes, having utterly destroyed the power and prestige of Sparta in Greece.
Reaching home, he was put on trial by certain enemies. He had broken the law by keeping command of the army four months beyond the allotted time. He appealed to the people, with what result we can readily understand. He was acquitted by acclamation, and he and Pelopidas were immediately re-elected Bœotarchs (or generals) for the coming year.
