67. This day both revived the spirits of the Romans and dismayed Perseus, so that after a few days' delay at Mopselus, more especially to attend to the burial of the soldiers who had been lost, having left a sufficiently strong garrison at Gonnus he retreated to Macedonia. [2] A certain Timotheus, one of the royal governors, he left with a small force at Phila, with orders to make overtures from near-by to the people of Magnesia. [3] When the king arrived at Pella, he sent his army into winter quarters and himself left with Cotys for Thessalonica. [4] There a report arrived that Autlesbis, a chieftain of the Thracians, and Corragus, Eumenes' governor,¹ had made an attack on the territory of Cotys and had captured the district called Marenê. [5] Therefore Perseus thought best to send Cotys back to protect his own, and marked his departure by great gifts. He paid two hundred talents,² a half-year's pay, to the cavalry, although he had planned at first to give a full year's amount.

[6] After the consul heard that Perseus had set out, he moved camp to Gonnus, in case he might be able to take the town. Placed in the entrance to Tempê itself, the town offers a very securely closed door to Macedonia and a sally-port to Thessaly favourable [p. 505]to the Macedonians. [7] Since both because of its³ situation and its strong garrison the city was impregnable, the consul abandoned the undertaking. Having turned aside to Perrhaebia, after capturing Malloea at the first assault and sacking it, and recovering the Tripolis and the rest of Perrhaebia, he returned to Larisa. [8] Thence having sent Eumenes and Attalus home, he assigned winter quarters in the nearest Thessalian cities to Misagenes and the Numidians, and scattered a portion of his army throughout all Thessaly in such a way that all had comfortable winter quarters and formed a protection for the cities. [9] His staff-officer Quintus Mucius⁴ he sent with two thousand to hold Ambracia. All the allies from the Greek states except the Achaeans he dismissed. With a part of his army he set out into Phthiotic Achaea,⁵ razed to the ground Pteleum, which had been abandoned by the flight of its inhabitants, and received Antronae by voluntary surrender of the inhabitants. [10] Then he brought his army up to Larisa. The city was abandoned; the whole population had taken refuge in the citadel; the consul advanced to attack this. [11] First of all the Macedonians, the king's garrison, departed in fear; deserted by these, the townsfolk immediately capitulated. Then as the consul debated whether he should first attack Demetrias or take a look at the situation in Boeotia, the Thebans, harassed by the people of Coronea, called him to Boeotia. [12] In answer to their entreaties, since for winter quarters⁶ the district was more suitable than Magnesia, he marched into Boeotia.
