12. Not merely in the same summer, but even practically during the same days when Marcus Fulvius the consul was thus engaged in Aetolia, the other consul Gnaeus Manlius in Gallograecia waged the war which I shall now proceed to describe. [2] The consul arrived in Ephesus in the beginning of spring, and, having taken over the troops from Lucius Scipio [p. 39]and purified¹ the army, he delivered a speech to the² soldiers in which he gave great praise to their valour [3??] because they had ended the war with Antiochus by a single battle, and urged them to undertake a new war with the Gauls, who had not only aided Antiochus with auxiliaries but possessed spirits so untamable that the expulsion of Antiochus beyond [4??] the ridges of the Taurus mountains would be in vain unless the power of the Gauls were broken, while as regards himself also he added brief remarks, neither false nor exaggerated.³ [5] The joyous soldiers listened to the consul with great applause, believing that the Gauls had been only a part of the forces of Antiochus; after the defeat of the king there would be no strength in the Gauls alone and by themselves. [6] The consul believed that Eumenes was away at an unsuitable time —he was then in Rome⁴ —as he was familiar with the country and the people and as it was to his interest that the power of the Gauls should be broken.⁵ [7] Manlius therefore summoned Eumenes' brother Attalus from Pergamum and urged him to join in the prosecution of the war, and on receiving the promise of the co-operation of himself and his countrymen sent him home to make preparations. [8] A few days later, when the consul left Ephesus for Magnesia, Attalus met him with a thousand infantry and five hundred cavalry, having directed his brother Athenaeus to follow with the rest of the army and having entrusted the guardianship of Pergamum to those men whom he deemed loyal to his brother and the throne. [9] The consul, praising the young man, marched with the [p. 41]entire force to the Meander and encamped, because⁶ the river could not be crossed by fording and boats had to be collected to ferry the army across. [10] After crossing the Meander they advanced to Hiera Comê.
