They also sent for Demosthenes, who had commanded the Athenian expedition against Aetolia, to be their leader; and for the twenty Athenian ships that happened to be cruising about the Peloponnese, under the command of Aristoteles son of Timocrates, and Hierophon son of Antimnestus.

The Ambraciots at Olpae also sent a messenger to their city, desiring them to come in full force to their assistance, fearing that the troops under Eurylochus might not be able to effect a passage through the Acarnanians, and that they themselves might either have to fight unsupported, or, if they wished to retreat, find it unsafe to do so.

The Peloponnesians with Eurylochus, therefore, finding that the Ambraciots at Olpae were come, set out from Proschium and went as quickly as possible to their aid; and having crossed the Acheloüs, proceeded through Acarnania, which was left deserted in consequence of the reinforcement sent to Argos; keeping on their right hand the city of the Stratians with their garrison, and on the left the rest of Acarnania.
