IV. Titus was advised by some to turn Philip's flank, marching through the Dassaretid country along the Lykus, which would offer no such difficulties; but he feared to march far from the coast lest, like his predecessors, he should become entangled in a country which could furnish no supplies, be unable to force Philip to fight, and be obliged to retreat to the sea again from want of the means of subsistence. He determined to force his way through the mountains in front, and as these were held by Philip with his main body, the phalanx, his flanks being secured by archers and light armed troops, skirmishes took place between him and the Romans daily, with considerable loss on both sides, but without any result, until some of the natives of the country informed him of a path, neglected by the enemy, by which they undertook to lead his army, and on the third day at the latest to place it upon the heights. As a guarantee of their good faith they referred the Romans to Charops, the chief of the Epirot tribes, who was friendly to the Romans, and co-operated with them secretly, being afraid of Philip. Titus trusting in this man's word sent one of the military tribunes with four thousand infantry and three hundred cavalry. They were guided by these peasants, who were strictly guarded, and marched by night, resting by day in woods and sheltered places: for the moon was full. Titus, after he had despatched this force, rested his army, only skirmishing slightly with the enemy lest they should entertain any suspicion, until the day upon which the turning party was expected to appear on the summit of the mountain range. On that morning he got his whole force under arms, light and heavy armed alike, and dividing it into three parts himself led one body in column up to the attack of the narrowest part of the pass beside the river, while the Macedonians shot at him from above and disputed every inequality of the ground, while on his right and left the other detachments likewise vigorously attacked the position. The sun rose while they were thus engaged, and a light cloud of smoke, not distinct, but like a mountain mist, rose from the captured heights. It was unnoticed by the enemy, being behind their backs, but kept the Romans, while they fought, in a state of hopeful excitement and suspense. When however it grew thicker and blacker, and rising in a cloud proved itself without doubt to be the looked-for signal, they rushed forward with a shout and drove the enemy into their innermost places of refuge, while those on the rocks above echoed their warlike clamour.
