History of the Peloponnesian War

The same summer, and about the same time that the Athenians stayed in Melos, those other Athenians that were in the thirty galleys about Peloponnesus slew first certain garrison soldiers in Ellomenus, a place of Leucadia, by ambush. But afterwards with a greater fleet and with the whole power of the Acarnanians, who followed the army, all (but the Oeniades) that could bear arms, and with the Zacynthians and Cephalonians and fifteen galleys of the Corcyraeans, made war against the city itself of Leucas.

The Leucadians, though they saw their territory wasted by them both without the isthmus and within where the city of Leucas standeth and the temple of Apollo, yet they durst not stir because the number of the enemy was so great. And the Acarnanians entreated Demosthenes, the Athenian general, to wall them up, conceiving that they might easily be expugned by a siege and desiring to be rid of a city their continual enemy.
