History of the Peloponnesian War

So Pythodorus, being now in command of Laches' ships, sailed at the close of the winter to the fort of the Locrians, which Laches had formerly taken; and returned after being defeated in battle by the Locrians.

Just about the beginning of this spring, the fire flood issued from Aetna, as it had done on former occasions, and destroyed some of the territory of the Catanaeans, who live on Mount Etna, the largest mountain in Sicily.

It is said that this eruption took place fifty years after the preceding one; and that it has occurred three times in all since Sicily has been inhabited by the Greeks.

These were the events of this winter; and so ended the sixth year of this war, of which Thucydides wrote the history.
