History of the Peloponnesian War

Meanwhile the Athenians, aware that the preparations of the enemy were due to his conviction of their weakness, and wishing to show him that he was mistaken, and that they were able, without moving the Lesbian fleet, to repel with ease that with which they were menaced from Peloponnese, manned a hundred ships by embarking the citizens of Athens, except the knights and Pentecosiomedimni, and the resident aliens; and putting out to the Isthmus, displayed their power, and made descents upon Peloponnese wherever they pleased.

A disappointment so signal made the Lacedaemonians think that the Lesbians had not spoken the truth; and embarrassed by the non-appearance of the confederates, coupled with the news that the thirty ships round Peloponnese were ravaging the lands near Sparta, they went back home.
