B.C. 381. With the first symptoms of approaching spring the Olynthian cavalry, six hundred strong, had swooped into the territory of Apollonia — about the middle of the day — and dispersing over the district, were employed in pillaging; but as luck would have it, Derdas had arrived that day with his troopers, and was breakfasting in Apollonia. He noted the enemy’s incursion, but kept quiet, biding his time; his horses were ready saddled, and his troopers armed cap-a-pied. As the Olynthians came galloping up contemptuously, not only into the suburbs, but to the very gates of the city, he seized his opportunity, and with his compact and well-ordered squadron dashed out; whereupon the invaders took to flight. Having once turned them, Derdas gave them no respite, pursuing and slaughtering them for ten miles or more,451 until he had driven them for shelter within the very ramparts of Olynthus. Report said that Derdas slew something like eighty men in this affair. After this the Olynthians were more disposed to keep to their walls, contenting themselves with tilling the merest corner of their territory.

Time advanced, and Teleutias was in conduct of another expedition against the city of Olynthus. His object was to destroy any timber452 still left standing, or fields still cultivated in the hostile territory. This brought out the Olynthian cavalry, who, stealthily advancing, crossed the river which washes the walls of the town, and again continued their silent march right up to the adversary’s camp. At sight of an audacity which nettled him, Teleutias at once ordered Tlemonidas, the officer commanding his light infantry division, to charge the assailants at the run. On their side the men of Olynthus, seeing the rapid approach of the light infantry, wheeled and quietly retired until they had recrossed the river, drawing the enemy on, who followed with conspicuous hardihood. Arrogating to themselves the position of pursuers towards fugitives, they did not hesitate to cross the river which stood between them and their prey. Then the Olynthian cavalry, choosing a favourable moment, when those who had crossed seemed easy to deal with, wheeled and attacked them, putting Tlemonidas himself to the sword with more than a hundred others of his company. Teleutias, when he saw what was happening, snatched up his arms in a fit of anger and began leading his hoplites swiftly forward, ordering at the same time his peltasts and cavalry to give chase and not to slacken. Their fate was the fate of many before and since, who, in the ardour of pursuit, have come too close to the enemy’s walls and found it hard to get back again. Under a hail of missiles from the walls they were forced to retire in disorder and with the necessity of guarding themselves against the missiles. At this juncture the Olynthians sent out their cavalry at full gallop, backed by supports of light infantry; and finally their heavy infantry reserves poured out and fell upon the enemy’s lines, now in thorough confusion. Here Teleutias fell fighting, and when that happened, without further pause the troops immediately about him swerved. Not one soul longer cared to make a stand, but the flight became general, some fleeing towards Spartolus, others in the direction of Acanthus, a third set seeking refuge within the walls of Apollonia, and the majority within those of Potidaea. As the tide of fugitives broke into several streams, so also the pursuers divided the work between them; this way and that they poured, dealing death wholesale. So perished the pith and kernel of the armament.

Such calamities are not indeed without a moral. The lesson they are meant to teach mankind, I think, is plain. If in a general sense one ought not to punish any one, even one’s own slave, in anger — since the master in his wrath may easily incur worse evil himself than he inflicts — so, in the case of antagonists in war, to attack an enemy under the influence of passion rather than of judgment is an absolute error. For wrath is but a blind impulse devoid of foresight, whereas to the penetrating eye of reason a blow parried may be better than a wound inflicted.453

When the news of what had happened reached Lacedaemon it was agreed, after due deliberation, that a force should be sent, and of no trifling description, if only to quench the victors’ pride, and to prevent their own achievements from becoming null and void. In this determination they sent out King Agesipolis, as general, attended, like Agesilaus454 on his Asiatic campaign, by thirty Spartans.455 Volunteers flocked to his standard. They were partly the pick and flower of the provincials,456 partly foreigners of the class called Trophimoi,457 or lastly, bastard sons of Spartans, comely and beautiful of limb, and well versed in the lore of Spartan chivalry. The ranks of this invading force were further swelled by volunteers from the allied states, the Thessalians notably contributing a corps of cavalry. All were animated by the desire of becoming known to Agesipolis, so that even Amyntas and Derdas in zeal of service outdid themselves. With this promise of success Agesipolis marched forward against Olynthus.

Meanwhile the state of Phlius, complimented by Agesipolis on the amount of the funds contributed by them to his expedition and the celerity with which the money had been raised, and in full belief that while one king was in the field they were secure against the hostile attack of the other (since it was hardly to be expected that both kings should be absent from Sparta at one moment), boldly desisted from doing justice by her lately reinstated citizens. On the one hand, these exiles claimed that points in dispute should be determined before an impartial court of justice; the citizens, on the other, insisted on the claimants submitting the cases for trial in the city itself. And when the latter demurred to that solution, asking “What sort of trial that would be where the offenders were also the judges?” they appealed to deaf ears. Consequently the restored party appealed at Sparta, to prefer a complaint against their city. They were accompanied by other members of the community, who stated that many of the Phliasians themselves besides the appellants recognised the injustice of their treatment. The state of Phlius was indignant at this manouvre, and retaliated by imposing a fine on all who had betaken themselves to Lacedaemon without a mandate from the state. Those who incurred the fine hesitated to return home; they preferred to stay where they were and enforce their views: “It is quite plain now who were the perpetrators of all the violence — the very people who originally drove us into exile, and shut their gates upon Lacedaemon; the confiscators of our property one day, the ruthless opponents of its restoration the next. Who else but they have now brought it about that we should be fined for appearing at Lacedaemon? and for what purpose but to deter any one else for the future from venturing to expose the proceedings at Phlius?” Thus far the appellants. And in good sooth the conduct of the men of Phlius did seem to savour of insolence; so much so that the ephors called out the ban against them.

B.C. 380. Nor was Agesilaus otherwise than well satisfied with this decision, not only on the ground of old relations of friendly hospitality between his father Archidamus and the party of Podanemus, who were numbered among the restored exiles at this time, but because personally he was bound by similar ties himself towards the adherents of Procles, son of Hipponicu............
