Philip V. In Illyria

As soon therefore as the Macedonians approached,

The Acrolissus taken by a feint, and Lissus afterwards.

they began pouring out of the town, confident in their numbers and in the strength of the places. The king stationed his peltasts on the level ground, and ordered the light-armed troops to advance towards the hills and energetically engage the enemy. These orders being obeyed, the fight remained doubtful for a time; but presently Philip's men yielded to the inequality of the ground, and the superior number of the enemy, and gave way. Upon their retreating within the ranks of the peltasts, the sallying party advanced with feelings of contempt, and having descended to the same level as the peltasts joined battle with them. But the garrison of the citadel seeing Philip moving his divisions one after the other slowly to the rear, and believing that he was abandoning the field, allowed themselves to be insensibly decoyed out, in their confidence in the strength of their fortifications; and thus, leaving the citadel by degrees, kept pouring down by bye-ways into the lower plain, under the belief that they would have an opportunity of getting booty and completing the enemy's discomfiture. Meanwhile the division, which had been lying concealed on the side of the mainland, rose without being observed, and advanced at a rapid pace. At their approach the peltasts also wheeled round and charged the enemy. On this the troops from Lissus were thrown into confusion, and, after a straggling retreat, got safely back into the town; while the garrison which had abandoned the citadel got cut off from it by the rising of the troops which had been lying in ambush. The result accordingly was that what seemed hopeless, namely the capture of the citadel, was effected at once and without any fighting; while Lissus did not fall until next day, and then only after desperate struggles, the Macedonians assaulting with vigour and even terrific fury. Thus Philip having, beyond all expectation, made himself master of these places, reduced by this exploit all the neighbouring populations to obedience; so much so that the greater number of the Illyrians voluntarily surrendered their cities to his protection; for it had come to be believed that, after the storming of such strongholds as these, no fortification and no provision for security could be of any avail against the might of Philip.
