There could hardly be a more fatal blow to Sparta than this loss to herself, and transfer to her enemies, of Tegea, the most powerful of her remaining allies.[448] To assist the exiles and avenge Stasippus, as well as to arrest the Arcadian movement, she resolved on a march into the country, in spite of her present dispirited condition; while Heræa and Lepreum, but no other places, sent contingents to her aid. From Elis and Argos, on the other hand, reinforcements came to Mantinea and Tegea. Proclaiming that the Mantineans had violated the recent peace by their entry into Tegea, Agesilaus marched across the border against them. The first Arcadian town which he reached was Eutæa,[449] where he found that all the male adults had gone to the great Arcadian assembly. Though the feebler population, remaining behind, were completely in his power, he took scrupulous care to respect both person and property, and even lent aid to rebuild a decayed portion of the wall. At Eutæa he halted a day or two, thinking it prudent to wait for the junction of the mercenary force and the Bœotian exiles under Polytropus, now at Orchomenus. Against the latter place, however, the Mantineans had marched under Lykomêdes, while Polytropus, coming forth from the walls to meet them, had been defeated with loss, and slain.[450] Hence Agesilaus was compelled to advance onward with his own unassisted forces, through the territory of Tegea up to the neighborhood of Mantinea. His onward march left the way from Asea to Tegea free, upon which the Arcadians assembled at Asea broke up, and marched by night to Tegea; from whence, on the next day, they proceeded to Mantinea, along the mountain range eastward of the Tegeatic plain; so that the whole Arcadian force thus became united. Agesilaus on his side, having ravaged the fields and encamped within little more than two miles from the walls of Mantinea, was agreeably surprised by the junction of his allies from Orchomenus, who had eluded by a night-march the vigilance of the enemy. Both on one side and on the other, the forces were thus concentrated. Agesilaus found himself on the first night, without intending it, embosomed in a recess of the mountains near Mantinea, where the Mantineans gathered on the high ground around, in order to attack him from above, the next morning. By a well-managed retreat, he extricated himself from this inconvenient position, and regained the plain; where he remained three days, prepared to give battle if the enemy came forth, in order that he might “not seem (says Xenophon) to hasten his departure through fear.”[451] As the enemy kept within their walls, he marched homeward, on the fourth day, to his former camp in the Tegean territory. The enemy did not pursue, and he then pushed on his march, though it was late in the evening, to Eutæa; “wishing (says Xenophon) to get his troops off before even the enemies’ fires could be seen, in order that no one might say that his return was a flight. He thought that he had raised the spirit of Sparta out of the previous discouragement, by invading Arcadia and ravaging the country without any enemy coming forth to fight him.”[452] The army was then brought back to Sparta and disbanded.
It had now become a matter of boast for Agesilaus (according to his own friendly historian) to keep the field for three or four days, without showing fear of Arcadians and Eleians! So fatally had Spartan pride broken down, since the day (less than eighteen months before) when the peremptory order had been sent to Kleombrotus, to march out of Phokis straight against Thebes!
Nevertheless it was not from fear of Agesilaus, but from a wise discretion, that the Arcadians and Eleians had kept within the walls of Mantinea. Epaminondas with the Theban army was approaching to their aid, and daily expected; a sum of ten talents having been lent by the Eleians to defray the cost.[453] He had been invited by them and by others of the smaller Peloponnesian states, who felt the necessity of some external protector against Sparta,—and who even before they applied to Thebes for aid, had solicited the like interference from Athens (probably under the general presidency accepted by Athens, and the oaths interchanged by her with various inferior cities, since the battle of Leuktra), but had experienced a refusal.[454]
Epaminondas had been preparing for this contingency ever since the battle of Leuktra. The first use made of his victory had been to establish or confirm the ascendency of Thebes both over the recusant Bœotian cities and over the neighboring Phokians and Lokrians, etc. After this had been accomplished, he must have been occupied (during the early part of 370 B.C.) in anxiously watching the movements of Jason of Pheræ,—who had already announced his design of marching with an imposing force to Delphi for the celebration of the Pythian games (about August 1.) Though this despot was the ally of Thebes, yet as both his power, and his aspirations towards the headship of Greece,[455] were well known, no Theban general, even of prudence inferior to Epaminondas, could venture in the face of such liabilities to conduct away the Theban force into Peloponnesus, leaving Bœotia uncovered. The assassination of Jason relieved Thebes from such apprehensions, and a few weeks sufficed to show that his successors were far less formidable in power as well as in ability. Accordingly, in the autumn of 370 B.C. Epaminondas had his attention free to turn to Peloponnesus, for the purpose both of maintaining the anti-Spartan revolution which had taken place in Tegea, and of seconding the pronounced impulse among the Arcadians towards federative coalition.
But the purposes of this distinguished man went farther still; embracing long-sighted and permanent arrangements, such as should forever disable Sparta from recovering her prominent station in the Grecian world. While with one hand he organized Arcadia, with the other he took measures for replacing the exiled Messenians on their ancient territory. To achieve this, it was necessary to dispossess the Spartans of the region once known as independent Messenia, under its own line of kings, but now, for near three centuries, the best portion of Laconia, tilled by Helots for the profit of proprietors at Sparta. While converting these Helots into free Messenians, as their forefathers had once been, Epaminondas proposed to invite back all the wanderers of the same race who were dispersed in various portions of Greece; so as at once to impoverish Sparta by loss of territory, and to plant upon her flank a neighbor bitterly hostile. It has been already mentioned, that during the Peloponnesian war, the exiled Messenians had been among the most active allies of Athens and Sparta,—at Naupaktus, at Sphakteria, at Pylus, in Kephallenia, and elsewhere. Expelled at the close of that war by the triumphant Spartans,[456] not only from Peloponnesus, but also from Naupaktus and Kephallenia, these exiles had since been dispersed among various Hellenic colonies; at Rhegium in Italy, at Messênê in Sicily, at Hesperides in Libya. From 404 B.C. (the close of the war) to 373 B.C., they had remained thus without a home. At length, about the latter year (when the Athenian confederate navy again became equal or superior to the Lacedæmonian on the west coast of Peloponnesus), they began to indulge the hope of being restored to Naupaktus.[457] Probably their request may have been preferred and discussed in the synod of Athenian allies, where the Thebans sat as members. Nothing however had been done towards it by the Athenians,—who soon became fatigued with the war, and at length made peace with Sparta,—when the momentous battle of Leuktra altered, both completely and suddenly, the balance of power in Greece. A chance of protection was now opened to the Messenians from Thebes, far more promising than they had ever had from Athens. Epaminondas, well aware of the loss as well as humiliation that he should inflict upon Sparta by restoring them to their ancient territory, entered into communication with them, and caused them to be invited to Peloponnesus from all their distant places of emigration.[458] By the time of his march into Arcadia, in the late autumn of 370 B.C., many of them had already joined him, burning with all their ancient hatred of Sparta, and contributing to aggravate the same sentiment among Thebans and allies.
With the scheme of restoring the Messenians, was combined in the mind of Epaminondas another, for the political consolidation of the Arcadians; both being intended as parts of one strong and self-supporting organization against Sparta on her own border. Of course he could have accomplished nothing of the kind, if there had not been a powerful spontaneous movement towards consolidation among the Arcadians themselves. But without his guidance and protection, the movement would have proved abortive, through the force of local jealousies within the country, fomented and seconded by Spartan aid from without. Though the general vote for federative coalition had been passed with enthusiasm, yet to carry out such a vote to the satisfaction of all, without quarrelling on points of detail, would have required far more of public-minded sentiment, as well as of intelligence, than what could be reckoned upon among the Arcadians. It was necessary to establish a new city; since the standing jealousy between Mantinea and Tegea, now for the first time embarked in one common cause, would never have permitted that either should be preferred as the centre of the new consolidation.[459] Besides fixing upon the new site required, it was indispensable also to choose between conflicting exigencies, and to break up ancient habits, in a way such as could hardly have been enforced by any majority purely Arcadian. The authority here deficient was precisely supplied by Epaminondas; who brought with him a victorious army and a splendid personal name, combined with impartiality as to the local politics of Arcadia, and single-minded hostility to Sparta.
It was with a view to these two great foundations, as well as to expel Agesilaus, that Epaminondas now marched the Theban army into Arcadia; the command being voluntarily intrusted to him by Pelopidas and the other Bœotarchs present. He arrived shortly after the retirement of Agesilaus, while the Arcadians and Eleians were ravaging the lands of the recusant town of Heræa. As they speedily came back to greet his arrival, the aggregate confederate body,—Argeians, Arcadians, and Eleians, united with the Thebans and their accompanying allies,—is said to have amounted to forty thousand, or according to some, even to seventy thousand men.[460] Not merely had Epaminondas brought with him a choice body of auxiliaries,—Phokians, Lokrians, Eubœans, Akarnanians, Herakleots, Malians, and Thessalian cavalry and peltasts,—but the Bœotian bands themselves were so brilliant and imposing, as to excite universal admiration. The victory of Leuktra had awakened among them an enthusiastic military ardor, turned to account by the genius of Epaminondas, and made to produce a finished discipline which even the unwilling Xenophon cannot refuse to acknowledge.[461] Conscious of the might of their assembled force, within a day’s march of Laconia, the Arcadians, Argeians, and Eleians pressed Epaminondas to invade that country, now that no allies could approach the frontier to its aid. At first he was unwilling to comply. He had not come prepared for the enterprise; being well aware, from his own journey to Sparta (when the peace-congress was held there prior to the battle of Leuktra), of the impracticable nature of the intervening country, so easy to be defended, especially during the winter-season, by troops like the Lacedæmonians, whom he believed to be in occupation of all the passes. Nor was his reluctance overcome until the instances of his allies were backed by assurances from the Arcadians on the frontier, that the passes were not all guarded; as well as by invitations from some of the discontented Periœki, in Laconia. These Periœki engaged to revolt openly, if he would only show himself in the country. They told him that there was a general slackness throughout Laconia in obeying the military requisitions from Sparta; and tendered their lives as atonement if they should be found to speak falsely. By such encouragements, as well as by the general impatience of all around him to revenge upon Sparta her long career of pride and abused ascendency, Epaminondas was at length induced to give the order of invasion.[462]
That he should have hesitated in taking this responsibility, will not surprise us, if we recollect, that over and above the real difficulties of the country, invasion of Laconia by land was an unparalleled phenomenon,—that the force of Sparta was most imperfectly known,—that no such thought had been entertained when he left Thebes,—that the legal duration of command, for himself and his colleagues, would not permit it,—and that though his Peloponnesian allies were forward in the scheme, the rest of his troops and his countrymen might well censure him, if the unknown force of resistance turned out as formidable as their associations from old time led them to apprehend.
The invading army was distributed into four portions, all penetrating by different passes. The Eleians had the westernmost and easiest road, the Argeians the easternmost;[463] while the Thebans themselves and the Arcadians formed the two central divisions. The latter alone experienced any serious resistance. More daring even than the Thebans, they encountered Ischolaus the Spartan at Ium or Oeum in the district called Skiritis, attacked him in the village, and overpowered him by vehemence of assault, by superior numbers, and seemingly also by some favor or collusion[464] on the part of the inhabitants. After a desperate resistance, this brave Spartan with nearly all his division perished. At Karyæ, the Thebans also found and surmounted some resistance; but the victory of the Arcadians over Ischolaus operated as an encouragement to all, so that the four divisions reached Sellasia[465] and were again united in safety. Undefended and deserted (seemingly) by the Spartans, Sellasia was now burnt and destroyed by the invaders, who, continuing their march along the plain or valley towards the Eurotas, encamped in the sacred grove of Apollo. On the next day they reached the Eurotas, at the foot of the bridge which crossed that river and led to the city of Sparta.
Epaminondas found the bridge too well-guarded to attempt forcing it; a strong body of Spartan hoplites being also discernible on the other side, in the sacred ground of Athênê Alea. He therefore marched down the left bank of the river, burning and plundering the houses in his way, as far as Amyklæ, between two and three miles below Sparta. Here he found a ford, though the river was full, from the winter season; and accomplished the passage, defeating, after a severe contest, a body of Spartans who tried to oppose it. He was now on the same side of the river as Sparta, to which city he slowly and cautiously made his approach; taking care to keep his Theban troops always in the best battle order, and protecting them, when encamped, by felled trees; while the Arcadians and other Peloponnesian allies dispersed around to plunder the neighboring houses and property.[466]
