Battle of MagnesiaManisa, Yunusemre/Manisa, Turk
The Battle of Magnesia was fought as part of the Roman–Seleucid War, pitting forces of the Roman Republic led by the consul Lucius Cornelius Scipio Asiaticus and the allied Kingdom of Pergamon under Eumenes II against a Seleucid army of Antiochus III the Great. The two armies initially camped north-east of Magnesia ad Sipylum in Asia Minor (modern-day Manisa, Turkey), attempting to provoke each other into a battle on favorable terrain for several days. When the battle finally began, Eumenes managed to throw the Seleucid left flank into disarray. While Antiochus' cavalry overpowered his adversaries on the right flank of the battlefield, his army's center collapsed before he could reinforce it. Modern estimates give 10,000 dead for the Seleucids and 5,000 killed for the Romans. The battle resulted in a decisive Roman-Pergamene victory, which led to the Treaty of Apamea, which ended Seleucid domination in Asia Minor.
