But when the Roman fleet arrived partly from Cane, partly from the Hellespont, and was after some time joined by twenty new ships of the Rhodians at Samos, Polyxenidas was once more compelled to shut himself up in the harbour of Ephesus. As he declined the offered naval battle, and as, owing to the small numbers of the Roman force, an attack by land was not to be thought of, nothing remained for the Roman fleet but to take up its position in like manner at Samos. A division meanwhile proceeded to Patara on the Lycian coast, partly to relieve the Rhodians from the very troublesome attacks that were directed against them from that quarter, partly and chiefly to prevent the hostile fleet, which Hannibal was expected to bring up, from entering the Aegean Sea. When the squadron sent against Patara achieved nothing, the new admiral Lucius Aemilius Regillus, who had arrived with 20 war-vessels from Rome and had relieved Gaius Livius at Samos, was so indignant that he proceeded thither with the whole fleet; his officers with difficulty succeeded, while they were on their voyage, in making him understand that the primary object was not the conquest of Patara but the command of the Aegean Sea, and in inducing him to return to Samos. On the mainland of Asia Minor Seleucus had in the meanwhile begun the siege of Pergamus, while Antiochus with his chief army ravaged the Pergamene territory and the possessions of the Mytilenaeans on the mainland; they hoped to crush the hated Attalids, before Roman aid appeared. The Roman fleet went to Elaea and the port of Adramytium to help their ally; but, as the admiral wanted troops, he accomplished nothing. Pergamus seemed lost; but the laxity and negligence with which the siege was conducted allowed Eumenes to throw into the city Achaean auxiliaries under Diophanes, whose bold and successful sallies compelled the Gallic mercenaries, whom Antiochus had entrusted with the siege, to raise it.
