21. The next day the king's outguards with better order and discipline established themselves five hundred paces farther from the city, and the Achaeans came out about the same time and to the same place. [2] For many hours both parties waited on the alert as if an attack were about to come; after the time, not far from sunset, of returning to camp had arrived, the royal troops, grouped around their standards,¹ began to depart in a formation adapted to marching rather than fighting. [3] Diophanes remained quiet as long as they were in sight; then, with the same impetuosity as the day before, he fell violently upon the rear and caused again so much panic and dismay that although they were being cut down from behind no one stood fast to fight; trembling and with difficulty keeping their march-formation they were driven back into camp. [4] This bold conduct of the Achaeans forced Seleucus to move his camp from the country of Pergamum.

When Antiochus heard that the Romans had come to defend Adramytteum, he left that city, at any [p. 353]rate, alone; but after laying waste their lands he² took by storm Peraea, a colony of the Mitylenaeans. [5] Cotto and Corylenus and Aphrodisias and Prinne fell at the first assault. Thence he returned to Sardis by way of Thyatira. Seleucus, remaining on the seacoast, was a source of fear to some and of assistance to others. [6] The Roman fleet with Eumenes and the Rhodians went first to Mitylene and then returned to Elaea whence it had come. [7] Then, on their way to Phocaea, they put in at the island which they call Bacchium —it overlooks the city of the Phocaeans —and when they had plundered like enemies the temples and shrines which they had not previously laid hands on —the island was beautifully adorned —they crossed to the city itself. [8] Dividing the tasks³ among themselves, they attacked it, and it seemed possible to take it without siege-works, by assault and escalade, but a garrison [9??] of three thousand armed soldiers, sent by Antiochus, entered the city, and at once the attack was abandoned and the fleet returned to the island, without doing anything other than devastating the farms of the enemy around the town.
