Thrace
Chapter 2 (13 references)
Almost immediately after this, fresh differences arose between the Athenians and Peloponnesians, and contributed their share to the war. Corinth was forming schemes for retaliation, and Athens suspected her hostility. The Potidaeans, who inhabit the isthmus of Pallene, being a Corinthian colony, but tributary allies of Athens, were ordered to raze the wall looking towards Pallene, to give hostages, to dismiss the Corinthian magistrates, and in future not to receive the persons sent from Corinth annually to succeed them. It was feared that they might be persuaded by Perdiccas and the Corinthians to revolt, and might draw the rest of the allies in the direction of Thrace to revolt with them. These precautions against the Potidaeans were taken by the Athenians immediately after the battle at Corcyra. Not only was Corinth at length openly hostile, but Perdiccas, son of Alexander, king of the Macedonians, had from an old friend and ally been made an enemy. He had been made an enemy by the Athenians entering into alliance with his brother Philip and Derdas, who were in league against him. In his alarm he had sent to Lacedaemon to try and involve the Athenians in a war with the Peloponnesians, and was endeavouring to win over Corinth in order to bring about the revolt of Potidaea. He also made overtures to the Chalcidians in the direction of Thrace, and to the Bottiaeans, to persuade them to join in the revolt; for he thought that if these places on the border could be made his allies, it would be easier to carry on the war with their co-operation. Alive to all this, and wishing to anticipate the revolt of the cities, the Athenians acted as follows. They were just then sending off thirty ships and a thousand heavy infantry for his country under the command of Archestratus, son of Lycomedes, with four colleagues. They instructed the captains to take hostages of the Potidaeans, to raze the wall, and to be on their guard against the revolt of the neighbouring cities.

Next we come to the actions by land and by sea at the river Eurymedon, between the Athenians with their allies, and the Medes, when the Athenians won both battles on the same day under the conduct of Cimon, son of Miltiades, and captured and destroyed the whole Phoenician fleet, consisting of two hundred vessels. Some time afterwards occurred the defection of the Thasians, caused by disagreements about the marts on the opposite coast of Thrace, and about the mine in their possession. Sailing with a fleet to Thasos, the Athenians defeated them at sea and effected a landing on the island. About the same time they sent ten thousand settlers of their own citizens and the allies to settle the place then called Ennea Hodoi or Nine Ways, now Amphipolis. They succeeded in gaining possession of Ennea Hodoi from the Edonians, but on advancing into the interior of Thrace were cut off in Drabescus, a town of the Edonians, by the assembled Thracians, who regarded the settlement of the place Ennea Hodoi as an act of hostility. Meanwhile the Thasians being defeated in the field and suffering siege, appealed to Lacedaemon, and desired her to assist them by an invasion of Attica. Without informing
