Some time after this, Orchomenus, Chaeronea, and some other places in Boeotia being in the hands of the Boeotian exiles, the Athenians marched against the above-mentioned hostile places with a thousand Athenian heavy infantry and the allied contingents, under the command of Tolmides, son of Tolmaeus. They took Chaeronea, and made slaves of the inhabitants, and, leaving a garrison, commenced their return. On their road they were attacked at Coronea by the Boeotian exiles from Orchomenus, with some Locrians and Euboean exiles, and others who were of the same way of thinking, were defeated in battle, and some killed, others taken captive. The Athenians evacuated all Boeotia by a treaty providing for the recovery of the men; and the exiled Boeotians returned, and with all the rest regained their independence.
This was soon afterwards followed by the revolt of Euboea from Athens. Pericles had already crossed over with an army of Athenians to the island, when news was brought to him that Megara had revolted, that the Peloponnesians were on the point of invading Attica, and that the Athenian garrison had been cut off by the Megarians, with the exception of a few who had taken refuge in Nisaea. The Megarians had introduced the Corinthians, Sicyonians, and Epidaurians into the town before they revolted. Meanwhile Pericles brought his army back in all haste from Euboea. After this the Peloponnesians marched into Attica as far as Eleusis and Thrius, ravaging the country under the conduct of King Pleistoanax, the son of Pausanias, and without advancing further returned home. The Athenians then crossed over again to Euboea under the command of Pericles, and subdued the whole of the island: all but Histiaea was settled by convention; the Histiaeans they expelled from their homes, and occupied their territory themselves.
Not long after their return from Euboea, they made a truce with the Lacedaemonians and their allies for thirty years, giving up the posts which they occupied in Peloponnese- Nisaea, Pegae, Troezen, and Achaia. In the sixth year of the truce, war broke out between the Samians and Milesians about Priene. Worsted in the war, the Milesians came to Athens with loud complaints against the Samians.
In this they were joined by certain private persons from Samos itself, who wished to revolutionize the government. Accordingly the Athenians sailed to Samos with forty ships and set up a democracy;took hostages from the Samians, fifty boys and as many men, lodged them in Lemnos, and after leaving a garrison in the island returned home. But some of the Samians had not remained in the island, but had fled to the continent. Making an agreement with the most powerful of those in the city, and an alliance with Pissuthnes, son of Hystaspes, the then satrap of Sardis, they got together a force of seven hundred mercenaries, and under cover of night crossed over to Samos. Their first step was to rise on the commons, most of whom they secured; their next to steal their hostages from Lemnos; after which they revolted, gave up the Athenian garrison left with them and its commanders to Pissuthnes, and instantly prepared for an expedition against Miletus. The Byzantines also revolted with them.
As soon as the Athenians heard the news, they sailed with sixty ships against Samos. Sixteen of these went to Caria to look out for the Phoenician fleet, and to Chios and Lesbos carrying round orders for reinforcements, and so never engaged; but forty-four ships under the command of Pericles with nine colleagues gave battle, off the island of Tragia, to seventy Samian vessels, of which twenty were transports, as they were sailing from Miletus. Victory remained with the Athenians. Reinforced afterwards by forty ships from Athens, and twenty-five Chian and Lesbian vessels, the Athenians landed, and having the superiority by land invested the city with three walls;it was also invested from the sea. Meanwhile Pericles took sixty ships from the blockading squadron, and departed in haste for Caunus and Caria, intelligence having been brought in of the approach of the Phoenician fleet to the aid of the Samians; indeed Stesagoras and others had left the island with five ships to bring them. But in the meantime the Samians made a sudden sally, and fell on the camp, which they found unfortified. Destroying the look-out vessels, and engaging and defeating such as were being launched to meet them, they remained masters of their own seas for fourteen days, and carried in and carried out what they pleased. But on the arrival of Pericles, they were once more shut up. Fresh reinforcements afterwards arrived- forty ships from Athens with Thucydides, Hagnon, and Phormio; twenty with Tlepolemus and Anticles, and thirty vessels from Chios and Lesbos. After a brief attempt at fighting, the Samians, unable to hold out, were reduced after a nine months' siege and surrendered on conditions; they razed their walls, gave hostages, delivered up their ships, and arranged to pay the expenses of the war by instalments. The Byzantines also agreed to be subject as before.
