13. About the same time Marcus Baebius and King Philip, who had already previously met in the country of the Dassaretii, when they had sent Appius Claudius into Thessaly to raise the siege of Larisa, and, because the time [2??] seemed too early for active campaigning, had returned to their winter quarters, at the beginning of spring joined their forces and marched down into Thessaly. [3] Antiochus was then in Acarnania. When they arrived, Philip attacked Malloea in Perrhaebia, and Baebius Phacium; when this fell at the first assault Baebius took Phaestum With the same speed. [4] When he had turned back from there to Atrax, he next occupied Cyretiae [p. 197]and Eritium, and establishing garrisons in the towns¹ he had recovered he rejoined Philip, who was still engaged in the siege of Malloea. [5] When at the coming of the Roman army the people of Malloea had surrendered, whether through fear of Roman might or in the hope of pardon, Baebius and Philip moved in one column to retake the towns which the Athamanes had occupied. [6] These were the following: Aeginium, Ericinium, Gomphi, Silana, Tricca, Meliboea, Phaloria.² Then Pellinaeum, where Philip of Megalopolis with [7??] five hundred infantry and forty cavalry was in the garrison, was surrounded, and before they stormed it they sent to Philip to advise him not to wish to try resistance to the last. [8] To this he replied with sufficient vehemence that he would entrust himself either to the Romans or to the Thessalians but would not put himself in the power of Philip.³ [9] When it was evident that force must be employed, because it seemed that Limnaeum could be stormed at the same time, it was decided that the king should go to Limnaeum while Baebius remained to attack Pellinaeum.
