History of the Peloponnesian War

Eurylochus and his men, perceiving that the army had entered and that it was impossible to take the town by storm, now withdrew, not to the Peloponnesus, but to the district of Aeolis, as it is now called, to Calydon, namely, and Pleuron, and the other towns of that region, and to Proschium in Aetolia.

For the Ambraciots came and urged him to join them in an attack upon Amphilochian Argos and the rest of Amphilochia, and at the same time upon Acarnania, saying that if they got control of these places all the mainland would be brought into alliance with the Lacedaemonians.
