After a time the Ambraciots expelled the Argives and held the city themselves.

Upon this the Amphilochians gave themselves over to the Acarnanians; and the two together called the Athenians, who sent them Phormio as general and thirty ships; upon whose arrival they took Argos by storm, and made slaves of the Ambraciots; and the Amphilochians and Acarnanians inhabited the town in common.

After this began the alliance between the Athenians and Acarnanians.

The enmity of the Ambraciots against the Argives thus commenced with the enslavement of their citizens; and afterwards during the war they collected this armament among themselves and the Chaonians, and other of the neighbouring barbarians.

Arrived before Argos, they became masters of the country; but not being successful in their attacks upon the town, returned home and dispersed among their different peoples.
Such were the events of the summer.
