But the Mytilenaeans got word of the expedition through a man who crossed over from Athens to Euboea, went thence by land to Geraestus, and, chancing there upon a merchantman that was putting to sea, took ship and on the third day after leaving Athens reached Mytilene. The Mytilenaeans, accordingly, not only did not go out to the temple of Apollo Maloeis, but barricaded the half-finished portions of the walls and harbours and kept guard.[*](Or, with Krüger, “but also guarded the other points after throwing barricades around the half-finished portions of the walls and harbours.”)
When not long afterwards the Athenians arrived and saw the state of affairs, their generals delivered their orders, and then, as the Mytilenaeans did not hearken to them, began hostilities.
But the Mytilenaeans, being unprepared for war and forced to enter upon it without warning, merely sailed out a short distance beyond their harbour, as though offering battle; then, when they had been chased to shore by the Athenian ships, they made overtures to the generals, wishing, if possible, to secure some sort of reasonable terms and thus to get rid of the fleet for the present.
The Athenian commanders accepted their proposals, being themselves afraid that they were not strong enough to make war against all Lesbos.
So the Mytilenaeans, having concluded an armistice, sent envoys to Athens, among whom was one of the informers who was by now repentant, in the hope that they might persuade them to recall their fleet, on the understanding that they themselves would not start a revolution.
Meanwhile they also sent envoys to Lacedaemon in a trireme, which eluded the Athenian fleet lying at anchor at Malea north of the town; for they had no confidence in the success of their negotiations with the Athenians.
These envoys, arriving at Lacedaemon after a hard voyage through the open sea, began negotiating for some aid for their countrymen.
But when the envoys to Athens returned without having accomplished anything, the people of Mytilene and the rest of Lesbos, except Methymna, began war; the Methymnaeans, however, supported the Athenians, as did also the Imbrians, Lemnians, and a few of the other allies.
