History of the Peloponnesian War

Meanwhile the Acarnanians went with a part of their forces to the relief of Argos, and with the rest encamped in Amphilochia at the place called Krenae, or the Wells, to watch for Eurylochus and his Peloponnesians, and to prevent their passing through and effecting their junction with the Ambraciots;

while they also sent for Demosthenes, the commander of the Aetolian expedition, to be their leader, and for the twenty Athenian ships that were cruising off Peloponnese under the command of Aristotle, son of Timocrates, and Hierophon, son of Antimnestus.

On their part, the Ambraciots at Olpae sent a messenger to their own city, to beg them to come with their whole levy to their assistance, fearing that the army of Eurylochus might not be able to pass through the Acarnanians, and that they might themselves be obliged to fight single-handed, or be unable to retreat, if they wished it, without danger.
