History of the Peloponnesian War

Not content with laying waste whatever had shot up in the parts which they had before devastated, the invaders now extended their ravages to lands passed over in their previous incursions; so that this invasion was more severely felt by the Athenians than any except the second;

the enemy staying on and on until they had overrun most of the country, in the expectation of hearing from Lesbos of something having been achieved by their fleet, which they thought must now have got over. However, as they did not obtain any of the results expected, and their provisions began to run short, they retreated and dispersed to their different cities.
