Under his command, the Romans crossed the Hellespont and sought Antiochus in his own kingdom.
Hannibal could do nothing with the poorly disciplined troops of the king.

They were met by the invading forces at MAGNESIA, in Lydia, in 190, and 80,000 Asiatics were put to rout by 30,000 Romans, 50,000 being slain.

The loss of the victors was slight.
On that day the fate of Asia was sealed.

Antiochus relinquished all pretensions to any territory west of the river Halys and the Taurus mountains.

His chariots, elephants, fleet, and treasures were all surrendered.
Scipio returned home to enjoy a triumph, and added ASIATICUS to his name, as his brother had taken that of Africanus in commemoration of his victory.
Gneius Manlius Vulso succeeded Scipio in the East.
