Pelopidas returning to his command in Thessaly, his usual success failed him. According to Diodorus and Plutarch, venturing as voluntary negotiator for his country within the power of the profligate tagus, he was seized and imprisoned. But Polybius imputes his misfortune to positive imprudence, and an expression of Demosthenes would imply that he was made prisoner in battle. Nor were the exertions of the Theban government to avenge him fortunate. The Bœotarchs, who had ventured far into Thessaly with an army said to have been eight thousand foot and six hundred horse, not finding the support expected from the Thessalian people, were reduced to retreat before the greater force of the tagus; and, in traversing the Thessalian plain pursued by a superior cavalry, they suffered severely. It is attributed to the ability of Epaminondas, serving in an inferior station, but called forth by the voices of the soldiers to supply the deficiencies of the generals, that the army was not entirely cut off. Negotiation, supported probably by arms, yet not without some concession, procured at length the release of Pelopidas, early in 367.
AN EMBASSY TO PERSIA AND A CONGRESS AT THEBES
[368-367 B.C.]
The cordial support of Athens, the force of mercenaries to be added by Philiscus, the growing aversion among the Arcadians to the Theban cause, and the troubles in the northern provinces, with the pressure of the Thessalian arms upon the Theban confederacy, together seemed likely to restore a decisive superiority to Lacedæmon, at least within her peninsula; and then, judging from experience, it was not likely to be confined there. But the able directors of the Theban councils had observed that the first and perhaps the most powerful efficient of this change in circumstances had been negotiation with Persia; and they resolved to direct also their attention to Persia, and try if they could not foil the Lacedæmonians by negotiation still more effectually than by arms. A minister from Lacedæmon, Euthycles, was actually resident at the Persian court. Upon this ground a congress of the confederacy was summoned, and, in pursuance of a common resolution, Pelopidas was sent to Susa on the part of Thebes, accompanied by ministers, from Argos, Elis, and Arcadia. The Athenians, jealous of the measure, sent their ministers also, Timagoras and Leon.
Pelopidas was treated by the Persian court with distinguishing honour. A Persian of rank was appointed to accompany Pelopidas back to Greece, bearing a rescript from the king in which the terms of his friendship were declared. It required that “the Lacedæmonians should allow the independency of Messenia; that the Athenians should lay up their fleet; that war should be made upon them if they refused; and that, if any Grecian city denied its contingent for such war, the first hostilities should be directed against that city; that those who accepted these terms would be considered as friends of the king, those who refused them as enemies.”
If we compare the style and spirit of this rescript, and the manner in which it was offered to united Greece, with the terms and circumstances of the Peace of Antalcidas, we shall hardly discover what has been the ground of distinction between them; why one has been so much reprobated, while the other, little indeed applauded, has in a manner been thrown out of observation by the imposing abundance of panegyric which the consent of ancient and modern writers has bestowed on the magnanimous patriotism of Pelopidas, and of his great associate in politics as in arms, Epaminondas. But we may perhaps be led to think that political principle has been out of view, both in the panegyric and in the reproach; that the merit of individuals has considerably swayed the general mind; yet that the great distinction has rested on party-spirit. If however, leaving the political principles of Pelopidas in that obscurity which we seem without means very satisfactorily to illuminate, we look to his political abilities, we shall see them exhibited in their fairest light, in real splendour, not by his professed panegyrists, but by the candid contemporary historian, not his friend. They are evident in the success of his Persian negotiation, to which that historian has borne full testimony; and that negotiation must unquestionably have been a business abounding with difficulties, and requiring much discernment to conduct and bring to so advantageous a conclusion.
