For as the Melians were islanders, and yet would not submit to them nor join their confederacy, they wished to reduce them.
When, however, they did not surrender to them on the wasting of their territory, they sailed to Oropus, on the coast opposite Attica; and having landed at night, the heavy-armed immediately marched from their ships to Tanagra in Boeotia;
while the Athenians in the city, on a given signal, met them at the same place by land in full force, under the command of Hipponicus son of Callias, and Eurymedon son of Thucles.
Having pitched their camp for that day in the territory of Tanagra, they laid it waste, and passed the night there. The next day, after defeating in battle those of the Tanagraeans and the Thebans who had come out against them, and after taking some arms, and erecting a trophy, they returned, one party to the city, the other to their fleet.
And Nicias, with his sixty ships, coasted along and ravaged the maritime parts of Locris, and then returned home.
