Volume 5 — CHAPTER XLV. PROCEEDINGS OF THE CONFEDERACY UNDER ATHENS AS HEAD. — FIRST FORMATION AND RAPID EXPANSION OF THE ATHENIAN EMPIRE. (continued 2)

So soon as the Lacedæmonians had retired from Attica, Periklês returned with his forces to Eubœa, and reconquered the island completely. With that caution which always distinguished him as a military man, so opposite to the fatal rashness of Tolmidês, he took with him an overwhelming force of fifty triremes and five thousand hoplites. He admitted most of the Eubœan towns to surrender, altering the government of Chalkis by the expulsion of the wealthy oligarchy called the Hippobotæ; but the inhabitants of Histiæa, at the north of the island, who had taken an Athenian merchantman and massacred all the crew, were more severely dealt with,—the free population being all or in great part expelled, and the land distributed among Athenian kleruchs, or out-settled citizens.[657]

But the reconquest of Eubœa was far from restoring Athens to the position which she had occupied before the fatal engagement of Korôneia. Her land empire was irretrievably gone, together with her recently acquired influence over the Delphian oracle; and she reverted to her former condition of an exclusively maritime potentate. For though she still continued to hold Nisæa and Pegæ, yet her communication with the latter harbor was now out off by the loss of Megara and its appertaining territory, so that she thus lost her means of acting in the Corinthian gulf, and of protecting as well as of constraining her allies in Achaia. Nor was the port of Nisæa of much value to her, disconnected from the city to which it belonged, except as a post for annoying that city. Moreover, the precarious hold which she possessed over unwilling allies had been demonstrated in a manner likely to encourage similar attempts among her maritime subjects,—attempts which would now be seconded by Peloponnesian armies invading Attica. The fear of such a combination of embarrassments, and especially of an irresistible enemy carrying ruin over the flourishing territory round Eleusis and Athens, was at this moment predominant in the Athenian mind. We shall find Periklês, at the beginning of the Peloponnesian war, fourteen years afterwards, exhausting all his persuasive force, and not succeeding without great difficulty, in prevailing upon his countrymen to endure the hardship of invasion,—even in defence of their maritime empire, and when events had been gradually so ripening as to render the prospect of war familiar, if not inevitable. But the late series of misfortunes had burst upon them so rapidly and unexpectedly, as to discourage even Athenian confidence, and to render the prospect of continued war full of gloom and danger. The prudence of Periklês would doubtless counsel the surrender of their remaining landed possessions or alliances, which had now become unprofitable, in order to purchase peace; but we may be sure that nothing short of extreme temporary despondency could have induced the Athenian assembly to listen to such advice, and to accept the inglorious peace which followed. A truce for thirty years was concluded with Sparta and her allies, in the beginning of 445 B. C., whereby Athens surrendered Nisæa, Pegæ, Achaia, and Trœzen,—thus abandoning Peloponnesus altogether,[658] and leaving the Megarians—with their full territory and their two ports—to be included among the Peloponnesian allies of Sparta.

It was to the Megarians, especially, that the altered position of Athens after this truce was owing: it was their secession from Attica and junction with the Peloponnesians, which laid open Attica to invasion. Hence, arose the deadly hatred on the part of the Athenians towards Megara, manifested during the ensuing years,—a sentiment the more natural, as Megara had spontaneously sought the alliance of Athens a few years before as a protection against the Corinthians, and had then afterwards, without any known ill-usage on the part of Athens, broken off from the alliance and become her enemy, with the fatal consequence of rendering her vulnerable on the land-side. Under such circumstances we shall not be surprised to find the antipathy of the Athenians against Megara strongly pronounced, insomuch that the system of exclusion which they adopted against her was among the most prominent causes of the Peloponnesian war.

Having traced what we may call the foreign relations of Athens down to this thirty years’ truce, we must notice the important internal and constitutional changes which she had experienced during the same interval.
