From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
The Macedonian and Roman armies--the latter of which had been reinforced by contingents of the Apolloniates and the Athamanes, by the Cretans sent by Nabis, and especially by a strong band of Aetolians--contained nearly equal numbers of combatants, each about 26,000 men; the Romans, however, had the superiority in cavalry. In front of Scotussa, on the plateau of the Karadagh, during a gloomy day of rain, the Roman vanguard unexpectedly encountered that of the enemy, which occupied a high and steep hill named Cynoscephalae, that lay between the two camps.
Driven back into the plain, the Romans were reinforced from the camp by the light troops and the excellent corps of Aetolian cavalry, and now in turn forced the Macedonian vanguard back upon and over the height. But here the Macedonians again found support in their whole cavalry and the larger portion of their light infantry; the Romans, who had ventured forward imprudently, were pursued with great loss almost to their camp, and would have wholly taken to flight, had not the Aetolian horsemen prolonged the combat in the plain until Flamininus brought up his rapidly-arranged legions.
The king yielded to the impetuous cry of his victorious troops demanding the continuance of the conflict, and hastily drew up his heavy-armed soldiers for the battle, which neither general nor soldiers had expected on that day. It was important to occupy the hill, which for the moment was quite denuded of troops.
