History of the Peloponnesian War

For the thirty years' truce which was made after the reduction of Euboea lasted fourteen years; but in the fifteenth year, when Chrysis was in the forty-eighth year of her priesthood at Argos, and Aenesias was ephor at Sparta, and Pythodorus had still two months to be archon at Athens; in the sixth month after the battle at Potidaea, and in the beginning of spring, rather more than three hundred men of the Thebans, (led by Pythangelus, son of Phylidas, and Diemporus, son of Onetorides, Boeotarchs,) about the first [*]( Literally first sleep. ) watch entered with their arms into Plataea, a town of Boeotia, which was in alliance with the Athenians.
