Meanwhile, the Peloponnesians in the forty ships, who ought to have made all haste to relieve Mitylene, lost time in coming round Peloponnese itself, and proceeding leisurely on the remainder of the voyage, made Delos without having been seen by the Athenians at Athens, and from thence arriving at Icarus and Myconus, there first heard of the fall of Mitylene.
Wishing to know the truth, they put into Embatum, in the Erythraeid, about seven days after the capture of the town. Here they learned the truth, and began to consider what they were to do; and Teutiaplus, an Elean, addressed them as follows:—
‘Alcidas and Peloponnesians who share with me the command of this armament, my advice is to sail just as we are to Mitylene, before we have been heard of.
We may expect to find the Athenians as much on their guard as men generally are who have just taken a city: this will certainly be so by sea, where they have no idea of any enemy attacking them, and where our strength, as it happens, mainly lies; while even their land forces are probably scattered about the houses in the carelessness of victory.
If therefore we were to fall upon them suddenly and in the night, I have hopes, with the help of the well-wishers that we may have left inside the town, that we shall become masters of the place.
