Histories

This was the fourth time that Dorians had come into Attica [23.5,38.83] (department), Central Greece and Euboea, Greece, Europe Attica. They had come twice as invaders in war and twice as helpers of the Athenian people. The first time was when they planted a settlement at +Megara [23.35,38] (Perseus) Megara [*](There is a clear tradition that this happened soon after the Dorian invasion of the +Peloponnese [22,37.5] (region), Greece, Europe Peloponnese.)(this expedition may rightly be said to have been in the reign of Codrus), the second and third when they set out from Sparta [22.4417,37.0667] (Perseus) Sparta to drive out the sons of Pisistratus, and the fourth was now, when Cleomenes broke in as far as +Eleusis [23.5583,38.0417] (Perseus) Eleusis with his following of Peloponnesians. This was accordingly the fourth Dorian invasion of Athens [23.7333,37.9667] (Perseus)Athens.

When this force then had been ingloriously scattered, the Athenians first marched against the Chalcidians to punish them. The Boeotians came to the Euripus to help the Chalcidians and as soon as the Athenians saw these allies, they resolved to attack the Boeotians before the Chalcidians.
