Editing Antiochus V Eupator (section)

===Downfall and death===
When the Roman Senate heard that the Syrian kingdom kept more warships and elephants than allowed by the [[Treaty of Apamea]] made in 188 BC, they sent a Roman embassy to travel along the cities of Syria and attempted to cripple Seleucid military power by sinking the Syrians' warships and [[hamstringing]] their elephants. Lysias dared do nothing to oppose the Romans, but his subservience so enraged his Syrian subjects that the Roman envoy [[Gnaeus Octavius (consul 165 BC)|Gnaeus Octavius]] was assassinated in [[Latakia|Laodicea]] in 162 BC.<ref name="auto"/>

At this juncture Demetrius escaped from Rome and was received in Syria as the true king. Antiochus V Eupator was soon put to death together with his protector Lysias.
