Passage 7.11.3
ἀφίκοντο δὲ ὡς τὸν Γάλλον καὶ Αἰτωλῶν οἱ Πλευρῶνα οἰκοῦντες, συντελείας τῆς ἐς Ἀχαιοὺς ἐθέλοντες ἄφεσιν εὕρασθαι· καὶ αὐτοῖς ἐπετράπη μὲν ὑπὸ τοῦ Γάλλου πρεσβείαν ἐπὶ σφῶν αὐτῶν ἰδίᾳ παρὰ Ῥωμαίους ἀποστεῖλαι, ἐπετράπη δὲ ὑπὸ Ῥωμαίων συνεδρίου τοῦ Ἀχαιῶν ἀποστῆναι. προσεπεστάλη δὲ ὑπὸ τῆς βουλῆς τῷ Γάλλῳ πόλεις ὁπόσας ἐστὶν οἷός τε ὡς πλείστας ἀφεῖναι συλλόγου τοῦ Ἀχαιῶν.
Those who dwelt in Pleuron approached Gallus along with the rest of the Aetolians, wishing to obtain release from their contribution to the Achaean League. Gallus permitted them privately to send their own embassy to the Romans, and the Romans allowed them to withdraw from the Achaean League's assembly. Furthermore, the Senate instructed Gallus to exempt as many cities as possible from membership in the Achaean confederation.
