15. The first city of Thessaly to be attacked was Phaloria. It had a garrison of two thousand Macedonians, which at first resisted with the greatest energy, using every resource for defence which their [p. 195]arms and fortifications gave them. [2] But the persistent¹ siege, relaxed by neither night nor day, since the consul thought that the attitude of the other Thessalians depended on whether the first had held out against the Roman attack, broke down the resistance of the Macedonians. [3] After the capture of Phaloria delegations came from Metropolis and Cierium offering the surrender of these cities. Their request was granted; Phaloria was burned and destroyed. [4] Then he proceeded against Aeginium; seeing that the place was very strong and almost impregnable, with even a small garrison, he hurled a few weapons against the outpost and turned his course towards the region around Gomphi. [5] And descending into the plains of Thessaly, since the army was now in want of everything, because he had spared the farms of the Epirotes, he sent scouts in advance to ascertain whether the supply-ships had headed for Leucas or the Ambracian gulf, and sent the cohorts in relays to Ambracia to provision; [6] and the road from Gomphi to Ambracia, while difficult and hard to travel, is short. [7] And so in a few days, the supplies having been transported from the fleet, the camp was full of an abundance of all things. Thence he marched to Atrax. [8] It is about ten miles from Larisa; its people are sprung from Perrhaebia; the town lies above the river Peneus. [9] At first the Thessalians felt no concern at the coming of the Romans; and as for Philip, while he did not dare himself to move into Thessaly, yet, established in a base camp within Tempe, he sent troops as occasion arose, as each point was threatened by the enemy.
