History of the Peloponnesian War

In some other respects also they were no longer liked in their government, as they had been; and while they did not join in the service on an equal footing, at the same time it was easy for them to bring to subjection those who revolted.

And for this the allies themselves were to blame; for owing to this aversion to expeditions, the greater part of them, to avoid being away from home, agreed to contribute money instead of ships as their quota of the expense; and so the fleet of the Athenians was increased from the funds which they contributed, while they themselves, whenever they revolted, found themselves unprepared and inexperienced for war.

After this was fought the battle at the river Eurymedon in Pamphylia, both by land and sea, between the Athenians and their allies and the Medes; and the Athenians were victorious in both engagements on the same day, under the command of Cimon, the son of Miltiades; and took and destroyed in all two hundred triremes of the Phoenicians.

Some time after it happened that the Thasians revolted from them, having quarrelled about the marts on the opposite coast of Thrace and the mine of which they were in possession. And the Athenians, having sailed with their fleet to Thasos, gained the victory in a sea-fight, and made a descent on their land.
