Now Pelopidas, being asleep in the camp, thought he saw the maidens weeping about their tombs, and cursing the Spartans, and Scedasus commanding, if they desired the victory, to sacrifice a virgin with chestnut hair to his daughters. Pelopidas looked on this as an harsh and impious injunction, but rose and told it to the prophets and commanders of the army, some of whom contended that it was fit to obey, and adduced as examples from the ancients, Menoeceus, son of Creon; Macaria, daughter of Hercules; and from later times, Pherecydes the philosopher, slain by the Lacedaemonians, and his skin, as the oracles advised, still kept by their kings. Leonidas, again, warned by the oracle, did as it were sacrifice himself for the good of Greece; Themistocles offered human victims to Bacchus Omestes, before the engagement at Salamis; and success showed their actions to be good. On the contrary, Agesilaus, going from the same place, and against the same enemies that Agamemnon did, and being commanded in a dream at Aulis to sacrifice his daughter, was so weak as to disobey;the consequence of which was, that his expedition was unsuccessful and inglorious. But some on the other side urged that such a barbarous and impious obligation could not be pleasing to any Superior Beings;that typhons and giants did not preside over the world, but the general father of gods and men; that it was absurd to imagine any divinities or powers delighted in slaughter and sacrifices of men; or, if there were such, they were to be neglected as weak and unable to assist; such unreasonable and cruel desires could only proceed from, and live in, weak and depraved minds.
The commanders thus disputing, and Pelopidas being in a great perplexity, a mare colt breaking from the herd, ran through the camp, and when she came to the place where they were stood still;and whilst some admired her bright chestnut colour, others her mettle, or the strength and fury of her neighing, Theocritus, the augur, took thought, and cried out to Pelopidas, "O good friend! look, the sacrifice is come; expect no other virgin, but use that which the gods have sent thee." With that they took the colt, and, leading her to the maidens' sepulchres, with the usual solemnity and prayers, offered her with joy, and spread through the whole army the account of Pelopidas's dream, and how they had given the required sacrifice.
In the battle, Epaminondas, bending his phalanx to the left, that, as much as possible, he might divide the right wing, composed of Spartans, from the other Greeks, and distress Cleombrotus by a fierce charge in column on that wing, the enemies perceived the design, and began to change their order, to open and extend their right wing, and, as they far exceeded him in number, to encompass Epaminondas. But Pelopidas with the three hundred came rapidly up, before Cleombrotus could extend his line, and close up his divisions, and so fell upon the Spartans while in disorder; though the Lacedaemonians, the expertest and most practised soldiers of all mankind, used to train and accustom themselves to nothing so much as to keep themselves from confusion upon any change of position, and to follow any leader, or right-hand man, and form in order, and fight on what part soever dangers press. In this battle, however, Epaminondas with his phalanx, neglecting the other Greeks, and charging them alone, and Pelopidas coming up with such incredible speed and fury, so broke their courage and baffled their art that there began such a flight and slaughter amongst the Spartans as was never before known. And so Pelopidas, though in no high office, but only captain of a small band, got as much reputation by the victory as Epaminondas, who was general and chief captain of Boeotia.
Into Peloponnesus, however, they both advanced together as colleagues in supreme command, and gained the greater part of the nations there from the Spartan confederacy; Elis, Argos, all Arcadia, and much of Laconia itself. It was the dead of winter, and but few of the last days of the month remained, and, in the beginning of the next, few officers were to succeed, and whoever failed to deliver up his charge forfeited his head. Therefore, the other chief captains fearing the law, and to avoid the sharpness of the winter, advised a retreat. But Pelopidas joined with Epaminondas, and, encouraging his countrymen, led them against Sparta, and, passing the Eurotas, took many of the towns, and wasted the country as far as the sea. This army consisted of seventy thousand Greeks, of which number the Thebans could not make the twelfth part;but the reputation of the men made all their allies contented to follow them as leaders, though no articles to that effect had been made. For, indeed, it seems the first and paramount law, that he that wants a defender is naturally a subject to him that is able to defend: as mariners, though in a calm or in the port they grow insolent, and brave the pilot, yet when a storm comes, and danger is at hand, they all attend, and put their hopes in him. So the Argives, Eleans, and Arcadians, in their congresses, would contend with the Thebans for superiority in command, yet in a battle, or any hazardous undertaking, of their own will followed their Theban captains. In this expedition they united all Arcadia into one body, and expelling the Spartans that inhabited Messenia, they called back the old Messenians, and established them in Ithome in one body;-and, returning through Cenchreae, they dispersed the Athenians, who designed to set upon them in the straits, and hinder their march.
