History of the Peloponnesian War

The Athenians were also joined, in accordance with the treaty, by a thousand horse of the Thessalians, who went over during the action to the Lacedaemonians.

A battle having been fought at Tanagra in Boeotia, the Lacedaemonians and their allies were victorious, and there was much bloodshed on both sides.

And the Lacedaemonians, after going into the Megarid and cutting down the fruit trees, returned back home across Geranea and the isthmus:

while the Athenians, on the sixty-second day after the battle, marched, under the command of Myronides, against the Boeotians, and having defeated them in an engagement at oenophyta, made themselves masters of the country of Boeotia and Phocis, and demolished the wall of the Tanagraeans, and took from the Opuntian Locrians their richest hundred men as hostages, and finished their own long walls.
