About the same time also Athenagoras, one of the king's generals, overtaking the Dardanians in their retreat homeward, at first threw their rear into disorder; but these unexpectedly facing about, and forming their line, the fight became like a regular engagement. [2] When the Dardanians began again to advance, the Macedonian cavalry and light infantry harassed those who had no troops of that kind to aid [p. 1386]them, and were, besides, burdened with unwieldy arms. The ground, too, favoured the assailants: very few were slain, but many wounded; none were taken, because they rarely quit their ranks, but both fight and retreat in a close body. [3] Thus Philip, having checked the proceedings of those two nations by these well-timed expeditions, gained reparation for the damages sustained from the operations of the Romans; the enterprise being as spirited as the issue was successful. [4] An occurrence which accidentally happened to him lessened the number of his enemies on the side of AEtolia. Scopas, a man of considerable influence in his own country, having been sent from Alexandria by king Ptolemy, with a great sum of gold, hired and carried away to Egypt six thousand foot and four hundred horse; [5] nor would he have suffered one of the young Aetolians to remain at home, had not Damocritus, (it is not easy to say, whether out of zeal for the good of the nation, or out of opposition to [6??] Scopas, for not having secured his interest by presents,) by sometimes reminding them of the war which threatened them, at other times, of [7??] the solitary condition in which they would be, detained some of them at home by severe reproaches. Such were the actions of the Romans, and of Philip, during that summer.
