Meanwhile the Achaeans, being hard pressed by the war, and ascertaining that the king was not far off, sent ambassadors to him begging for help. They found Philip still in his camp near Stratus, and there delivered their commission: and besides the message with which they were charged, they pointed out to him the richness of the booty which his army would get from the enemy’s country, and tried to persuade him to cross to Rhium and invade Elis. The king listened to what they had to say, and kept the ambassadors with him, alleging that he must consider of their request; and meanwhile broke up his camp, and marched in the direction of Metropolis and Conope. The Aetolians kept possession of the citadel of Metropolis but abandoned the town: whereupon Philip set fire to Metropolis, and continued his advance against Conope. But when the Aetolian horse rallied and ventured to meet him at the ford of the Achelous, which is about twenty stades before you reach the town, believing that they would either stop his advance altogether, or inflict much damage on the Macedonians while crossing the river; the king, fully understanding their tactics, ordered his light-armed troops to enter the river first and to cross it in close order, keeping to their regular companies, and with shields interlocked. His orders were obeyed: and as soon as the first company had effected the crossing, the Aetolian cavalry attacked it; but they could make no impression upon it, standing as it did in close order, and being joined in similar close order, shield to shield, by a second and a third company as they crossed. Therefore they wheeled off discomfited and retired to the city. From this time forth the proud gallantry of the Aetolians was fain to confine itself to the protection of the towns, and keep quiet; while Philip crossed with his army, and after wasting this district also without resistance, arrived at Ithoria. This is a position completely commanding the road, and of extraordinary strength, natural as well as artificial. On his approach, however, the garrison occupying the place abandoned it in a panic; and the king, taking possession, levelled it to the ground: and gave orders to his skirmishing parties to treat all forts in the district in the same way.
