Flamininus lay still encamped near the sanctuary of Thetis and, being in doubt as to where the enemy were, he pushed forward ten squadrons of horse and about a thousand light-armed infantry, sending them out with orders to go over the ground reconnoitring cautiously.
In proceeding towards the pass over the hills they encountered the Macedonian covering force quite unexpectedly owing to the obscurity of the army.
Both forces were thrown somewhat into disorder for a short time but soon began to take the offensive, sending to their respective commanders messengers to inform them of what had happened.
When in the combat that ensued the Romans began to be overpowered and to suffer loss at the hands of the Macedonian covering force they sent to their camp begging for help,
and Flamininus, calling upon Archedamus and Eupolemus the Aetolians and two of his military tribunes,
sent them off with five hundred horse and two thousand foot.
For the Romans, encouraged by the arrival of the reinforcements, fought with redoubled vigour,
and the Macedonians, though defending themselves gallantly, were in their turn pressed hard, and upon being completely overmastered, fled to the summits and sent to the king for help.
