According to the modern theories of government, to declare war, to make peace, and to contract alliances, are functions proper to be intrusted to the executive government apart from the representative assembly. According to ancient ideas, these were precisely the topics most essential to submit for the decision of the full assembly of the people: and in point of fact they were so submitted, even under governments only partially democratical; much more, of course, under the complete democracy of Athens. The Korkyræan envoys, on reaching that city, would first open their business to the stratêgi, or generals of the state, who would appoint a day for them to be heard before the public assembly, with full notice beforehand to the citizens. The mission was no secret, for the Korkyræans had themselves intimated their intention at Corinth, at the time when they proposed reference of the quarrel to arbitration: and even without such notice, the political necessity of the step was obvious enough to make the Corinthians anticipate it. Lastly, their proxeni at Athens, Athenian citizens who watched over Corinthian interests, public and private, in confidential correspondence with that government,—and who, sometimes by appointment, sometimes as volunteers, discharged partly the functions of ambassadors in modern times, would communicate to them the arrival of the Korkyræan envoys. So that, on the day appointed for the latter to be heard before the public assembly, Corinthian envoys were also present to answer them and to oppose the granting of their prayer.

Thucydidês has given in his history the speeches of both; that is, speeches of his own composition, but representing in all probability the substance of what was actually said, and of what he perhaps himself heard. Though pervaded throughout by the peculiar style and harsh structure of the historian, these speeches are yet among the plainest and most business-like in his whole work, bringing before us thoroughly the existing situation; which was one of doubt and difficulty, presenting reasons of considerable force on each of the opposite sides. The Korkyræans, after lamenting their previous improvidence, which had induced them to defer seeking alliance until the hour of need arrived, presented themselves as claimants for the friendship of Athens, on the strongest grounds of common interest and reciprocal usefulness. Though their existing danger and want of Athenian support was now urgent, it had not been brought upon them in an unjust quarrel, or by disgraceful conduct: they had proposed to Corinth a fair arbitration respecting Epidamnus, and their application had been refused,—which showed where the right of the case lay; moreover, they were now exposed single-handed, not to Corinth alone, whom they had already vanquished, but to a formidable confederacy, organized under her auspices, including choice mariners hired even from the allies of Athens. In granting their prayer, Athens would, in the first place, neutralize this misemployment of her own mariners, and would, at the same time, confer an indelible obligation, protect the cause of right, and secure to herself a most important reinforcement. For, next to her own, the Korkyræan naval force was the most powerful in Greece, and this was now placed within her reach: if, by declining the present offer, she permitted Korkyra to be overcome, that naval force would pass to the side of her enemies: for such were Corinth and the Peloponnesian alliance,—and such they would soon be openly declared. In the existing state of Greece, a collision between that alliance and Athens could not long be postponed: and it was with a view to this contingency that the Corinthians were now seeking to seize Korkyra along with her naval force.[103] The policy of Athens, therefore, imperiously called upon her to frustrate such a design, by now assisting the Korkyræans. She was permitted to do this by the terms of the thirty years’ truce: and although some might contend that, in the present critical conjuncture, acceptance of Korkyra was tantamount to a declaration of war with Corinth, yet the fact would falsify such predictions; for Athens would so strengthen herself that her enemies would be more than ever unwilling to attack her. She would not only render her naval force irresistibly powerful, but would become mistress of the communication between Sicily and Peloponnesus, and thus prevent the Sicilian Dorians from sending reinforcements to the Peloponnesians.[104]

To these representations on the part of the Korkyræans, the Corinthian speakers made reply. They denounced the selfish and iniquitous policy pursued by Korkyra, not less in the matter of Epidamnus, than in all former time,[105]—which was the real reason why she had ever been ashamed of honest allies. Above all things, she had always acted undutifully and wickedly towards Corinth, her mother-city, to whom she was bound by those ties of colonial allegiance which Grecian morality recognized, and which the other Corinthian colonies cheerfully obeyed.[106] Epidamnus was not a Korkyræan, but a Corinthian colony, and the Korkyræans, having committed wrong in besieging it, had proposed arbitration without being willing to withdraw their troops while arbitration was pending: they now impudently came to ask Athens to become accessory after the fact in such injustice. The provision of the thirty years’ truce might seem indeed to allow Athens to receive them as allies: but that provision was not intended to permit the reception of cities already under the tie of colonial allegiance elsewhere,—still less the reception of cities engaged in an active and pending quarrel, where any countenance to one party in the quarrel was necessarily a declaration of war against the opposite. If either party had a right to invoke the aid of Athens on this occasion, Corinth had a better right than Korkyra: for the latter had never had any transactions with the Athenians, while Corinth was not only still under covenant of amity with them, through the thirty years’ truce,—but had also rendered material service to them by dissuading the Peloponnesian allies from assisting the revolted Samos. By such dissuasion, the Corinthians had upheld the principle of Grecian international law, that each alliance was entitled to punish its own refractory members: they now called upon Athens to respect this principle, by not interfering between Corinth and her colonial allies,[107] especially as the violation of it would recoil inconveniently upon Athens herself, with her numerous dependencies. As for the fear of an impending war between the Peloponnesian alliance and Athens, such a contingency was as yet uncertain,—and might possibly never occur at all, if Athens dealt justly, and consented to conciliate Corinth on this critical occasion: but it would assuredly occur if she refused such conciliation, and the dangers thus entailed upon Athens would be far greater than the promised naval coöperation of Korkyra would compensate.[108]

Such was the substance of the arguments urged by the contending envoys before the Athenian public assembly, in this momentous debate. For two days did the debate continue, the assembly being adjourned over to the morrow: so considerable was the number of speakers, and probably also the divergence of their views. Unluckily, Thucydidês does not give us any of these Athenian discourses,—not even that of Periklês, who determined the ultimate result. Epidamnus, with its disputed question of metropolitan right, occupied little of the attention of the Athenian assembly: but the Korkyræan naval force was indeed an immense item, since the question was, whether it should stand on their side or against them,—an item which nothing could counterbalance except the dangers of a Peloponnesian war. “Let us avoid this last calamity (was the opinion of many) even at the sacrifice of seeing Korkyra conquered, and all her ships and seamen in the service of the Peloponnesian league.” “You will not really avoid it, even by that great sacrifice (was the reply of others): the generating causes of war are at work,—and it will infallibly come, whatever you may determine respecting Korkyra: avail yourselves of the present opening, instead of being driven ultimately to undertake the war at great comparative disadvantage.” Of these two views, the former was at first decidedly preponderant in the assembly;[109] but they gradually came round to the latter, which was conformable to the steady conviction of Periklês. It was, however, resolved to take a sort of middle course, so as to save Korkyra, and yet, if possible, to escape violation of the existing truce and the consequent Peloponnesian war. To comply with the request of the Korkyræans, by adopting them unreservedly as allies, would have laid the Athenians under the necessity of accompanying them in an attack of Corinth, if required,—which would have been a manifest infringement of the truce. Accordingly, nothing more was concluded than an alliance for purposes strictly defensive, to preserve Korkyra and her possessions in case they were attacked: nor was any greater force equipped to back this resolve than a squadron of ten triremes, under Lacedæmonius, son of Kimon. The smallness of this force would satisfy the Corinthians that no aggression was contemplated against their city, while it would save Korkyra from ruin, and would in fact feed the war so as to weaken and cripple the naval force of both parties,[110]—which was the best result that Athens could hope for. The instructions to Lacedæmonius and his two colleagues were express; not to engage in fight with the Corinthians unless they were actually approaching Korkyra, or some Korkyræan possession, with a view to attack: but in that case to do his best on the defensive.

The great Corinthian armament of one hundred and fifty sail soon took its departure from the gulf, and reached a harbor on the coast of Epirus, at the cape called Cheimerium, nearly opposite to the southern extremity of Korkyra: they there established a naval station and camp, summoning to their aid a considerable force from the friendly Epirotic tribes in the neighborhood. The Korkyræan fleet of one hundred and ten sail, under Meikiadês and two others, together with the ten Athenian ships, took station at one of the adjoining islands called Sybota, while the land force and one thousand Zakynthian hoplites were posted on the Korkyræan Cape Leukimmê. Both sides prepared for battle: the Corinthians, taking on board three days’ provisions, sailed by night from Cheimerium, and encountered in the morning the Korkyræan fleet advancing towards them, distributed into three squadrons, one under each of the three generals, and having the ten Athenian ships at the extreme right. Opposed to them were ranged the choice vessels of the Corinthians, occupying the left of their aggregate fleet: next came the various allies, with Megarians and Ambrakiots on the extreme right. Never before had two such numerous fleets, both Grecian, engaged in battle; but the tactics and manœuvring were not commensurate to the numbers. The decks were crowded with hoplites and bowmen, while the rowers below, on the Korkyræan side at least, were in great part slaves: the ships, on both sides, being rowed forward so as to drive in direct impact, prow against prow, were grappled together, and a fierce hand-combat was then commenced between the troops on board of each, as if they were on land,—or rather, like boarding-parties: all upon the old-fashioned system of Grecian sea-fight, without any of those improvements which had been introduced into the Athenian navy during the last generation. In Athenian naval attack, the ship, the rowers, and the steersman, were of much greater importance than the armed troops on deck: by strength and exactness of rowing, by rapid and sudden change of direction, by feints calculated to deceive, the Athenian captain sought to drive the sharp beak of his vessel, not against the prow, but against the weaker and more vulnerable parts of his enemy,—side, oars, or stern. The ship thus became in the hands of her crew the real weapon of attack, which was first to disable the enemy and leave him unmanageable on the water; and not until this was done did the armed troops on deck begin their operations.[111] Lacedæmonius, with his ten armed ships, though forbidden by his instructions to share in the battle, lent as much aid as he could by taking station at the extremity of the line, and by making motions as if about to attack; while his seamen had full leisure to contemplate what they would despise as the lubberly handling of the ships on both sides. All was confusion after the battle had been joined; the ships on both sides became entangled, the oars broken and unmanageable, orders could neither be heard nor obeyed, and the individual valor of the hoplites and bowmen on deck was the decisive point on which victory turned.

On the right wing of the Corinthians, the left of the Korkyræans was victorious; their twenty ships drove back the Ambrakiot allies of Corinth, and not only pursued them to the shore, but also landed and plundered the tents. Their rashness in thus keeping so long out of the battle proved incalculably mischievous, the rather as their total number was inferior: for their right wing, opposed to the best ships of Corinth, was after a hard struggle thoroughly beaten. Many of the ships were disabled, and the rest obliged to retreat as they could,—a retreat which the victorious ships on the other wing might have protected, had there been any effective discipline in the fleet, but which now was only imperfectly aided by the ten Athenian ships under Lacedæmonius. These Athenians, though at first they obeyed the instructions from home, in abstaining from actual blows, yet,—when the battle became doubtful, and still more, when the Corinthians were pressing their victory,—could no longer keep aloof, but attacked the pursuers in good earnest, and did much to save the defeated Korkyræans. As soon as the latter had been pursued as far as their own island, the victorious Corinthians returned to the scene of action, which was covered with disabled and water-logged ships, their own and their enemies, as well as with seamen, soldiers, and wounded men, either helpless aboard the wrecks, or keeping above water as well as they could,—among them many of their own citizens and allies, especially on their defeated right wing. Through these disabled vessels they sailed, not attempting to tow them off, but looking only to the crews aboard, and making some of them prisoners, but putting the greater number to death: some even of their own allies were thus slain, not being easily distinguishable. They then picked up their own dead bodies as well as they could, and transported them to Sybota, the nearest point of the coast of Epirus; after which they again mustered their fleet, and returned to resume the attack against the Korkyræans on their own coast. The latter got together as many of their ships as were seaworthy, together with the small reserve which had remained in harbor, in order to prevent at any rate a landing on the coast: and the Athenian ships, now within the strict letter of their instructions, prepared to coöperate with full energy in the defence. It was already late in the afternoon: but the Corinthian fleet, though their pæan had already been shouted for attack, were suddenly seen to back water instead of advancing; presently they headed round, and sailed directly away to the Epirotic coast. Nor did the Korkyræans comprehend the cause of this sudden retreat, until at length it was proclaimed that an unexpected relief of twenty fresh Athenian ships was approaching, under Glaukon and Andokidês, which the Corinthians had been the first to descry, and had even believed to be the forerunners of a larger fleet. It was already dark when these fresh ships reached Cape Leukimmê, having traversed the waters covered with wrecks and dead bodies;[112] and at first the Korkyræans even mistook them for enemies. The reinforcement had been sent from Athens, probably after more accurate information of the comparative force of Corinth and Korkyra, under the impression that the original ten ships would prove inadequate for the purpose of defence,—an impression more than verified by the reality.

Though the twenty Athenian ships were not, as the Corinthians had imagined, the precursors of a larger fleet, they were found sufficient to change completely the face of affairs. In the preceding action, the Korkyræans had had seventy ships sunk or disabled,—the Corinthians only thirty,—so that the superiority of numbers was still on the side of the latter, who were, however, encumbered with the care of one thousand prisoners, eight hundred of them slaves, captured, not easy either to lodge or to guard in the narrow accommodations of an ancient trireme. Even apart from this embarrassment, the Corinthians were in no temper to hazard a second battle against thirty Athenian ships, in addition to the remaining Korkyræan: and when their enemies sailed across to offer them battle on the Epirotic coast, they not only refused it, but thought of nothing but immediate retreat,—with serious alarm lest the Athenians should now act aggressively, treating all amicable relations between Athens and Corinth as practically extinguished by the events of the day before. Having ranged their fleet in line, not far from shore, they tested the dispositions of the Athenian commanders by sending forward a little boat with a few men to address to them the following remonstrance,—the men carried no herald’s staff (we should say, no flag of truce), and were therefore completely without protection against an enemy. “Ye act wrongfully, Athenians (they exclaimed), in beginning the war and violating the truce; for ye are using arms to oppose us in punishing our enemies. If it be really your intention to hinder us from sailing against Korkyra, or anywhere else that we choose, in breach of the truce, take first of all us who now address you, and deal with us as enemies.” It was not the fault of the Korkyræans that this last idea was not instantly realized: for such of them as were near enough to hear, instigated the Athenians by violent shouts to kill the men in the boat. But the latter, far from listening to such an appeal, dismissed them with the answer: “We neither begin the war nor break the truce, Peloponnesians; we have come simply to aid these Korkyræans, our allies. If ye wish to sail anywhere else, we make no opposition: but if ye are about to sail against Korkyra, or any of her possessions, we shall use our best means to prevent you.” Both the answer, and the treatment of the men in the boat, satisfied the Corinthians that their retreat would be unopposed, and they accordingly commenced it as soon as they could get ready, staying, however, to erect a trophy at Sybota, on the Epirotic coast, in commemoration of their advantage on the preceding day. In their voyage homeward, they surprised Anaktorium, at the mouth of the Ambrakiôtic gulf, which they had hitherto possessed jointly with the Korkyræans; planting in it a reinforcement of Corinthian settlers as guarantee for future fidelity. On reaching Corinth, the armament was disbanded, and the great majority of the prisoners taken—eight hundred slaves—were sold; but the remainder, two hundred and fifty in number, were detained and treated with peculiar kindness. Many of them were of the first and richest families of the island, and the Corinthians designed to gain them over, so as to make them instruments for effecting a revolution in the island. The calamitous incidents arising from their return will appear in a future chapter.

Thus relieved from all danger, the Korkyræans picked up the dead bodies and the wrecks which had floated during the night on to their island, and even found sufficient pretence to erect a trophy, chiefly in consequence of their partial success on the left wing. In truth, they had been only rescued from ruin by the unexpected coming of the last Athenian ships: but the last result was as triumphant to them as it was disastrous and humiliating to the Corinthians, who had incurred an immense cost, and taxed all their willing allies, only to leave their enemy stronger than she was before. From this time forward they considered the thirty years’ truce as broken, and conceived a hatred, alike deadly and undisguised, against Athens; so that the latter gained nothing by the moderation of her admirals in sparing the Corinthian fleet off the coast of Epirus. An opportunity was not long wanting for the Corinthians to strike a blow at their enemy, through one of her wide-spread dependencies.

On the isthmus of that lesser peninsula called Pellênê, which forms the westernmost of the three prongs of the greater peninsula called Chalkidikê, between the Thermaic and the Strymonic gulfs, was situated the Dorian town of Potidæa, one of the tributary allies of Athens, but originally colonized from Corinth, and still maintaining a certain metropolitan allegiance towards the latter: insomuch that every year certain Corinthians were sent thither as magistrates, under the title of Epidemiurgi. On various points of the neighboring coast, also, there were several small towns belonging to the Chalkidians and Bottiæans, enrolled in like manner in the list of Athenian tributaries. The neighboring inland territory, Mygdonia and Chalkidikê,[113] was held by the Macedonian king Perdikkas, son of that Alexander who had taken part, fifty years before, in the expedition of Xerxes. These two princes appear gradually to have extended their dominions, after the ruin of Persian power in Thrace by the exertions of Athens, until at length they acquired all the territory between the rivers Axius and Strymon. Now Perdikkas had been for some time the friend and ally of Athens; but there were other Macedonian princes, his brother Philip and Derdas, holding independent principalities in the upper country,[114] apparently on the higher course of the Axius near the Pæonian tribes, with whom he was in a state of dispute. These princes having been accepted as the allies of Athens, Perdikkas from that time became her active enemy, and it was from his intrigues that all the difficulties of Athens on that coast took their first origin. The Athenian empire was much less complete and secure over the seaports on the mainland than over the islands:[115] for the former were always more or less dependent on any powerful land-neighbor, sometimes more dependent on him than upon the mistress of the sea; and we shall find Athens herself cultivating assiduously the favor of Sitalkês and other strong Thracian potentates, as an aid to her dominion over the seaports.[116] Perdikkas immediately began to incite and aid the Chalkidians and Bottiæans to revolt from Athens, and the violent enmity against the latter, kindled in the bosoms of the Corinthians by the recent events at Korkyra, enabled him to extend the same projects to Potidæa. Not only did he send envoys to Corinth in order to concert measures for provoking the revolt of Potidæa, but also to Sparta, instigating the Peloponnesian league to a general declaration of war against Athens.[117] And he farther prevailed on many of the Chalkidian inhabitants to abandon their separate small towns on the sea-coast, for the purpose of joint residence at Olynthus, which was several stadia from the sea. Thus that town, as well as the Chalkidian interest, became much strengthened, while Perdikkas farther assigned some territory near Lake Bolbê to contribute to the temporary maintenance of the concentrated population.

The Athenians were not ignorant both of his hostile preparations and of the dangers which awaited them from Corinth after the Korkyræan sea-fight; immediately after which they sent to take precautions against the revolt of Potidæa; requiring the inhabitants to take down their wall on the side of Pellênê, so as to leave the town open on the side of the peninsula, or on what may be called the sea-side, and fortified only towards the mainland,—requiring them farther both to deliver hostages and to dismiss the annual magistrates who came to them from Corinth. An Athenian armament of thirty triremes and one thousand hoplites, under Archestratus and ten others, despatched to act against Perdikkas in the Thermaic gulf, was directed at the same time to enforce these requisitions against Potidæa, and to repress any dispositions to revolt among the neighboring Chalkidians. Immediately on receiving these requisitions, the Potidæans sent envoys both to Athens, for the purpose of evading and gaining time,—and to Sparta, in conjunction with Corinth, in order to determine a Lacedæmonian invasion of Attica, in the event of Potidæa being attacked by Athens. From the Spartan authorities they obtained a distinct affirmative promise, in spite of the thirty years’ truce still subsisting: at Athens they had no success, and they accordingly openly revolted (seemingly about midsummer, 432 B.C.), at the same time that the armament under Archestratus sailed. The Chalkidians and Bottiæans revolted at the same time, at the express instigation of Corinth, accompanied by solemn oaths and promises of assistance.[118] Archestratus with his fleet, on reaching the Thermaic gulf, found them all in proclaimed enmity, but was obliged to confine himself to the attack of Perdikkas in Macedonia, not having numbers enough to admit of a division of his force. He accordingly laid siege to Therma, in coöperation with the Macedonian troops from the upper country, under Philip and the brothers of Derdas; after taking that place, he next proceeded to besiege Pydna. But it would probably have been wiser had he turned his whole force instantly to the blockade of Potidæa; for during the period of more than six weeks that he spent in the operations against Therma, the Corinthians conveyed to Potidæa a reinforcement of sixteen hundred hoplites and four hundred light-armed, partly their own citizens, partly Peloponnesians, hired for the occasion,—under Aristeus, son of Adeimantus, a man of such eminent popularity, both at Corinth and at Potidæa, that most of the soldiers volunteered on his personal account. Potidæa was thus put into a state of complete defence shortly after the news of its revolt reached Athens, and long before any second armament could be sent to attack it. A second armament, however, was speedily sent forth.—forty triremes and two thousand Athenian hoplites, under Kallias, son of Kalliades,[119] with four other commanders,—who, on reaching the Thermaic gulf, joined the former body at the siege of Pydna. After prosecuting the siege in vain for a short time, they found themselves obliged to patch up an accommodation on the best terms they could with Perdikkas, from the necessity of commencing immediate operations against Aristeus and Potidæa. They then quitted Macedonia, first crossing by sea from Pydna to the eastern coast of the Thermaic gulf,—next attacking, though without effect, the town of Berœa,—and then marching by land along the eastern coast of the gulf, in the direction of Potidæa. On the third day of easy march, they reached the seaport called Gigônus, near which they encamped.[120]
