13. The next day the consul followed the enemy along the defile through which the river makes its [p. 189]way down the valley. [2] The king on the first day¹ reached the camp of Pyrrhus; the place called by this name is in Triphylia and belongs to the territory of Molottis. The next day —an over-long march for an army, but fear drove them on —they reached thence the Lyncus mountains. [3] This range is in Epirus, lying between Macedonia and Thessaly; the side which overlooks Thessaly faces east, the northern, Macedonia. It is clothed with abundant forests; the summits of the ridges offer open fields and ever-flowing springs. [4] There Philip remained in camp for several days, uncertain in mind whether he should straightway return to his kingdom or try to beat the enemy into Thessaly. [5] His decision was to lead the army into Thessaly, and he moved to Tricca by the shortest routes; then he rapidly traversed the towns in his way. He summoned from their homes the men who could follow; the towns he burned. [6] The owners were allowed to carry with them what they could of their possessions; the rest was booty for the army. [7] Nor was there any hardship unexperienced, which an enemy could inflict, greater than what they suffered at the hands of their allies. Such actions were distasteful to Philip even as he did them, but he wished [8] to rescue, from a land that was soon to belong to his enemies, at least the persons of his allies. So Phacium, Iresiae, Euhydrium, Eretria, Palaepharsalus, were destroyed. [9] Excluded from Pherae, when he tried to take it, because it would require time if he tried to capture it, and he had no time, he gave up that undertaking and crossed into Macedonia; for it was rumoured that the Aetolians were close at hand. [10] They, having heard of the battle at [p. 191]the Aous river, and having laid waste the country² close around Sperchiae and Macra, which they call, Come, crossed thence into Thessaly and captured Cymene and Angeia at the first assault. From Metropolis, while they were devastating the farms, they were driven back, the townsmen having collected to defend their walls. [11] When they attacked Callithera they sustained more stubbornly a similar sally of townspeople; and driving back within their own walls the party that had made the sally, they departed, content with this success, because they had no real hope of capturing the town. [12] Next they took and sacked the villages of Teuma and Celathara and received Acharrae in surrender. Xyniae was abandoned by the inhabitants in similar fear. [13] The procession of its citizens, exiles from their homes, fell in with a garrison which was on its way to Thaumacus,³ that it might forage in greater security; [14] the undisciplined and unarmed mass, mingled too with the unwarlike mob, was slaughtered by the soldiers,. The abandoned city of Xyniae was looted. The Aetolians next captured Cyphaera, a fortress favourably situated to threaten Dolopia. Such is the record of the Aetolians' swift campaign of a few days. [15] Nor did Amynander and the Athamanes remain quiet after they heard of the Roman victory.
