EXPEDITION INTO THESSALY
Greek Officer sacrificing on the Eve of Battle
The war with Thessaly now pressed upon Thebes. Still urging Lacedæmon by her confederates and dependents in Peloponnesus, she not only could afford protection to her northern subjects and allies against the successor of the most formidable potentate of the age, but she could aim at dominion, or influence which would answer the purpose of dominion, among the populous and wealthy, but ill-constituted cities of Thessaly. While the rapacity and ambition of the tagus, Alexander of Pheræ, occasioned a necessity for measures of protection and defence, the disposition to revolt, which his tyranny had excited among those over whom his authority extended, gave probability to views of aggrandisement for those who might support the revolt. Accordingly Pelopidas was sent into Thessaly with an army under a commission to act there at his discretion; for the advantage however, not of the Thessalians, who had solicited protection, but of the Bœotian people, who pretended to be common protectors: a kind of commission which it has been usual in all ages for the barefaced ambition of democracies to avow, while the more decent manners of the most corrupt courts, from which such commissions may have issued, have generally covered them with a veil. Pelopidas penetrated to Larissa, and with the co-operation of its people, expelled the tyrant’s garrison. Extending negotiations then into Macedonia, he concluded a treaty with Alexander, king of that country, who desired alliance with Thebes, the better to resist the oppression which he felt or feared from the naval power and ambitious policy of Athens, which were continually exerted to extend dominion or influence over every town on every shore of the Ægean. His younger brother, Philip, then a boy, afterwards the great Philip, father of the greater Alexander, is said to have accompanied Pelopidas in his return to Thebes; whether for advantage of education and to extend friendly connection, or, as later writers have affirmed, as a hostage to insure the performance of stipulated conditions.
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.
