History of the Peloponnesian War

As he went by the coast, he landed at Cos Meropidis, being unwalled and thrown down by an earthquake which had happened there, the greatest verily in man's memory, and rifled it, the inhabitants being fled into the mountains; and overrunning the country, made booty of all that came in his way, saving of freemen, and those he dismissed.

From Cos he went by night to Cnidus, but found it necessary, by the advice of the Cnidians, not to land his men there, but to follow as he was after those twenty galleys of Athens, wherewith Charminus, one of the Athenian generals gone out from Samos, stood watching for those twenty-seven galleys that were come from Peloponnesus, the same that Astyochus himself was going to convoy in.

For they at Samos had had intelligence from Miletus of their coming; and Charminus was lying for them about Syme, Chalce, Rhodes, and the coast of Lycia; for by this time he knew that they were at Caunus.

Astyochus, therefore, desiring to outgo the report of his coming, went as he was to Syme, hoping to find those galleys out from the shore. But [a shower of] rain, together with the cloudiness of the sky, made his galleys to miss their course in the dark and disordered them.
