156. Only three islands in the neighboring seas now maintained their independence, and of these the most important was Samos. The Milesians, who had some cause of complaint against the Samians, appealed to the arbitration of Athens, and were joined by a party in Samos itself which was opposed to the oligarchy. The Athenians readily assumed the judgment of the case, and as Samos refused their arbitration, resolved to conquer the island. Pericles with a fleet proceeded to Samos, revolutionized the government, and brought away hostages from the most powerful families. But no sooner was he departed than some of the deposed party returned by night, overpowered the Athenian garrison, and restored the oligarchy. They gained possession of their hostages, who had been deposited on the Isle of Lemnos, and being joined by Byzantium, declared open war against Athens.
157. When the news of this event reached Athens, a fleet of sixty vessels was immediately sent forth, Pericles being one of the ten commanders. Several battles were fought by sea, and the Samians were at length driven within the walls of their capital, where they endured a nine months’ siege. When at last they were forced to yield, they were compelled to destroy their fortifications, surrender their fleet, give hostages for their future conduct, and pay the expenses of the war. The Byzantines submitted at the same time. Athens was completely triumphant; but the terror she had inspired was mixed with jealousy. During the revolt, the rival states had seriously discussed the question of aiding the rebels; and it was decided in the negative mainly by the influence of Corinth, which, though no friend to Athens, feared that the precedent might be remembered in case of a revolt of her own colonies.

158. Corcyra, a colony of Corinth, had itself founded, on the Illyrian coast, the city of Epidamnus. This city, attacked by the Illyrians, led by some of her own exiled nobles, sent to Corcyra for aid, but was refused, as the exiles belonged to the party in power in the mother city. The Epidamnians now resorted to Corinth, which undertook their defense with great energy. Corcyra, alarmed in turn, applied to Athens for assistance. Opinions were divided in the assembly, but that of Pericles prevailed, who urged that war could not in any case be long delayed, and that it was more prudent to make it in alliance with Corcyra, whose fleet was, next to that of Athens, the most powerful in Greece, than to be driven at last to fight at a disadvantage.
Considering, however, that Corinth, as an ally of Sparta, was included in the thirty years’ truce, it was resolved to make only a defensive alliance with Corcyra; i.e., to render assistance in case its territories should be invaded, but not to take part in any aggressive action. A naval battle soon occurred off the coast of Epirus, in which the Corinthians were the victors, and prepared to effect a landing in Corcyra. Ten Athenian vessels were present, under the command of Lacedæmonius, son of Cimon, and they were now, by the letter of their agreement, free to engage. But suddenly, after the signal of battle had been given, the Corinthians drew back and stood away for the coast of Epirus. Twenty Athenian ships had appeared in the distance, which they imagined to be the vanguard of a large fleet. Though this was a mistake, it had the effect of preventing further hostilities, and the Corinthians returned home with their prisoners.

159. Incensed at the interference of Athens, the Corinthians sought revenge by uniting with Prince Perdic´cas of Macedonia, to stir up revolts among the Athenian tributaries in the Chalcidic peninsulas. A battle ensued at Olynthus, in which the Athenians were victorious over the Corinthian general, and blockaded him in Potidæa, where he had taken refuge.
A congress of the Peloponnesian states was held at Sparta, and complaints from many quarters were uttered against Athens. The Æginetans deplored the loss of their independence; the Megarians, the crippling of their trade; the Corinthians, that they were overshadowed by the towering ambition of their powerful neighbor. At the same time, the Corinthians contrasted the restless activity of Athens with the selfish inertness of Sparta, and threatened that if the latter still delayed to do her duty by the League, they would seek a more efficient ally.
The envoys having departed, Sparta decided to undertake the war. Before proceeding to actual hostilities, it was thought best to send messengers to Athens, demanding, among other things, that she should “expel the accursed” from her presence—referring to Pericles, whose race they chose to consider as still tainted with sacrilege. But Pericles replied that the Spartans themselves had heavy accounts to settle on the score of sacrilege, not only for starving Pausanias in the sanctuary of Athena, but for dragging away and murdering the Helots who had taken refuge, during the late revolt, in the temple of Posidon. The other demands were rejected, though with more hesitation. They concerned the independence of Megara and Ægina, and, generally, the abdication by Athens of her position as head of the League. The Athenians declared that they would refrain from commencing hostilities, and would make just satisfaction for any infringement on their part of the thirty years’ truce; but that they were ready to meet force with force.
