Eurylochus and his forces advance upon Demosthenes' right wing and threaten to overwhelm it. The Messenians in ambush spring up and attack Eurylochus' left wing from behind. The Peloponnesian line breaks; they panic and flee, "terrified beyond measure at seeing the division of Eurylochus and their best troops cut to pieces." "Most of the work was done by Demosthenes and his Messenians." The Ambracians on the Spartan right wing defeat the opposing Athenian forces and pursue them to Argos. Returning, they find that the Acarnanians have defeated their main forces in the center. The battle ends at evening, with the Spartans capitulating and requesting a truce.
