History of the Peloponnesian War

The Peloponnesians, after they had taken twenty-two Athenian galleys with the men, whereof some they slew and some they took prisoners, erected a trophy; and not long after, having caused all Euboea to revolt save only Oreus, which the Athenians held with their own forces, they settled the rest of their business there.

When the news of that which had happened in Euboea was brought to Athens, it put the Athenians into the greatest astonishment that ever they had been in before. For neither did their loss in Sicily, though then thought great, nor any other at any time so much affright them as this.

For now when the army at Samos was in rebellion, when they had no more galleys nor men to put aboard, when they were in sedition amongst themselves and in continual expectation of falling together by the ears, then in the neck of all arrived this great calamity, wherein they not only lost their galleys, but also, which was worst of all, Euboea, by which they [had] received more commodity than by Attica.
