When the Aetolians returned from Rome and told the Aetolian leaders there was no hope of peace, the Aetolians seized the passage at Mount Corax so they could block off the pass. The Achaeans began ravaging the coast of Aetolia facing the Peloponnese. The Aetolians expected Acilius to attack Naupactus again but instead he launched a sudden attack on Lamia. The Lamians, despite the great confusion, managed to repulse the first attack. Acilius rallied his men and told them to only come back to camp once they had captured the city, which they did, a few hours later.
