THE OLYNTHIAN WAR
[383 B.C.]
More serious complications in Greek affairs soon gave the Spartans their opportunity for showing themselves masters of Hellas. In the spring of 383 ambassadors from the cities of Apollonia and Acanthus presented themselves in Sparta to beg for support against the increasing power of the Olyntho-Chalcidian league. Their petition was seconded by deputies from Amyntas, king of Macedonia, who felt the security of his dominions imperilled by the encroachments of Olynthus. The Olynthians strove more and more vigorously to assert the authority of the league. They had succeeded in persuading nearly all the cities of the Chalcidice to join their confederacy; they had pushed forward towards Macedonia, and had even brought Pella over to their interests. The league was now in a position to hold the menace of war over any cities which refused adherence, and to meditate far-reaching enterprises. By an agreement with Athens and Thebes it hoped to secure an influence upon middle Greece. By this energetic and well-considered centralisation a federal state was created, admirably calculated to serve as a bulwark of the power of Hellas against Thrace, and as a fresh starting-point for the civilisation of the barbarous North.
As we look back at the lines along which the history of Greece developed, we are inevitably forced upon the conclusion that nothing but strict union, the formation of closely confederated states, could have checked the rapid process of political decay. This conviction lies at the root of the liberal recognition and sympathy which the majority of modern scholars have accorded to the efforts of the Olynthian league. Whether the brilliant visions of the future which Grote, in particular, sketches for the league would ever have been realised, even if it had not fallen upon the days of Sparta’s arbitrary dominion, remains an open question. Centralisation and unification were repugnant to the Greek mind, and every attempt in that direction was bound to go to wreck on the fanatical love of autonomy among the Greek states.
The appeal of Apollonia and Acanthus, which wished to retain their ancient constitution, and the simultaneous action of the oppressed Amyntas, offered Sparta the desired opportunity for attacking the Chalcidic federation. Doubtless the sea power of Olynthus and the steady expansion of the league had long since attracted general attention there, and had been the subject of anxious reflection. The possibility that this league might grow more powerful still and attain an authoritative position in middle Greece also had to be guarded against at all risks. The policy of Sparta rendered it imperative that every considerable development of power in other states should be repressed. The war against the Olynthians was determined upon, and, by the desire of the ambassadors, Eudamidas was immediately despatched with such forces as could be equipped in haste.
THE SURPRISE OF THEBES
[383-380 B.C.]
His brother Phœbidas was to follow with the remainder of the troops destined for the campaign in Thrace as soon as the levies were completed, a process which was probably rendered more lengthy by the fact that the new military system was now brought into use for the first time. By the end of summer, 383, Phœbidas was ready to start. He took his way past Thebes. There, as Xenophon tells, party quarrels had reached an extreme point. The office of polemarch was held by Leontiades and Ismenias, who were deadly enemies, each being the leader of a distinct body of partisans. For the moment the anti-Laconian party was in the ascendant. A decree had been promulgated that no man should be allowed to enlist for the campaign against Olynthus. When Phœbidas appeared before the walls of the city, Leontiades, whose family had always maintained close relations with Sparta, endeavoured to gain his favour by every kind of service, and then persuaded the vain and ambitious general to attempt a coup-de-main against the Cadmea. By this means he was to bring the adherents of Sparta into power and secure the active assistance of Thebes in the Olynthian War.
Phœbidas fell in with the proposed plot, and the day of the feast of the Thesmophoria was appointed for its execution. On that day the women of the city celebrated by themselves a festival in the ancient temple of Demeter on the Cadmea. Phœbidas was to make a feint of striking camp and setting out on his march northwards. While the council was assembled in a hall in the market-place and the heat of noon-day kept the rest of the population indoors, Leontiades galloped after the departing general, led him unobserved up to the citadel, and opened the gates to him. He then hied to the council, announced what had taken place, and had Ismenias arrested as a seditious person. The leaders and adherents of the opposition, to the number of three hundred, were obliged to flee for their lives to Athens. The occupation of the Cadmea was a political necessity, the logical consequence of the efforts of Sparta to secure the hegemony. The experiences of the last war had not been suffered in vain.
While Agesilaus was pursuing his victorious career in Asia a coalition against Sparta had been formed in Greece at the instigation of Persia, and Thebes had shown herself most zealous in promoting this anti-Spartan combination which was so grave a menace to the existence of Lacedæmon. This time Sparta was once more undertaking a war on the confines of Greece; if fortune were adverse, if a battle were lost, she had no guarantee against the possibility—the probability even—that hostile Thebes, still barely subdued, might revolt again, bar the way of retreat against the Spartan army, and throw the most serious obstacles in the way of reinforcements. “The Cadmea was the decisive point for the security of the line of march,” says Curtius. If a prolonged war were to be waged in the distant north it was essential that this position should be in friendly hands. And the only way of attaining this object was to juggle the reins of government into the hands of the oligarchical party in Thebes and to garrison the citadel with Spartan hoplites for their protection. The success of the expedient proves how well worth while it had been for Phœbidas to take the circuitous route.
