In July 190 BC, Hannibal ordered his fleet to set sail from Seleucia Pieria along the southern Asia Minor coast in order to reinforce the rest of the Seleucid navy at Ephesus. The following month Hannibal's fleet clashed with the Rhodian navy in the Battle of Side. The faster Rhodian ships managed to heavily damage half of Hannibal's warships through the maneuver, forcing him to retreat. Hannibal had preserved most of his fleet, however he was in no position to unite with Polyxenidas' fleet at Ephesus since his ships required lengthy repairs. The ensuing Battle of Myonessus resulted in a Roman-Rhodian victory, which cemented Roman control over the Aegean Sea, enabling them to launch an invasion of Seleucid Asia Minor. The two armies faced off in the decisive Battle of Magnesia, north-east of Magnesia ad Sipylum. The battle resulted in a decisive Roman-Pergamene victory. The truce was signed at Sardes in January 189 BC, whereupon Antiochus agreed to abandon his claims on all lands west of the Taurus Mountains, paid a heavy war indemnity and promised to hand over Hannibal and other notable enemies of Rome from among his allies.
