History of the Peloponnesian War

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 Coronaea, 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.
