History of the Peloponnesian War

So these galleys went their way. And ten galleys of Mytilene which then chanced to be at Athens, by virtue of their league to aid them, the Athenians stayed and cast into prison the men that were in them.

In the meantime a certain man went from Athens into Euboea by sea and then by land to Geraestus and, finding there a ship ready to put off, having the wind favourable, arrived in Mytilene three days after he set forth from Athens and gave them notice of the coming of the fleet. Hereupon they not only went not out to Maloeis, as was expected, but also stopped the gaps of their walls and ports where they were left unfinished and placed guards to defend them.

When the Athenians not long after arrived and saw this, the commanders of the fleet delivered to the Mytilenaeans what they had in charge, which not hearkened unto, they presently fell to the war.
