The armies marched the whole day without having sight of each other in any place, the view being intercepted by a continued range of hills between them.  The Romans encamped at Eretria, in Phthiotis; Philip, on the river Onchestus.  But though Philip lay at Melambius, in the territory of Scotussa, and Quinctius near Thetidium, in Pharsalia, neither party knew with any certainty where his antagonist was.  On the third day, there first fell a violent rain, which was succeeded by darkness equal to that of night, and this confined the Romans to their camp, through fear of an ambuscade.

7.  Philip, intent on hastening his march, and in no degree deterred by the clouds, which after the rain lowered over the face of the country, ordered his troops to march:  and yet so thick a fog had obscured the day, that neither the standard-bearers could see the road, nor the soldiers the standards; so that all, led blindly by the shouts of uncertain guides, fell into disorder, like men wandering by night.  When they had passed over the hills called Cynoscephalae, where they set a strong guard of foot and horse, they pitched their camp.  Although the Roman general staid at Thetidium, yet he detatched troops of horse and one thousand foot, to find out where the enemy lay; warning them, however, to beware of ambuscades, which the darkness of the day would cover, even in an open country.  When these arrived at the hills, where the enemy’s guard was posted, struck with mutual fear, both parties stood, as if deprived of the power of motion.  They then sent back messengers to their respective commanders; and when the first surprise subsided, they proceeded to action without more delay.  The fight was begun by small advanced parties; and afterwards the numbers of the combatants were increased by reinforcements of men, who supported those who gave way.  In this contest the Romans, being far inferior to their adversaries, sent message after message to the general, that they were being overpowered; on which he hastily sent five hundred horse and two thousand foot, mostly Aetolians, under the command of two military tribunes, who relieved them, and restored the fight.  The Macedonians, distressed in turn by this change of fortune, sent to beg succour from their king; but as, on account of the general darkness from the fog, he had expected nothing less, on that day, than a battle, and had therefore sent a great number of men, of every kind, to forage, he was, for a considerable time, in great perplexity, and unable to form a resolution.  Subsequently, as the messengers still continued to urge him, and the covering of clouds was now removed from the tops of the mountains, and the Macedonian party was in view, having been driven up to the highest summit, and trusting for safety rather to the nature of the ground than to their arms, he thought it necessary, at all events, to hazard the whole, in order to prevent the loss of a part, for want of support; and, accordingly,
