Host Trevor Cully details Antiochus III’s eastern campaign to reconquer Parthia and Bactria, highlighting the Battle of the Arius and the subsequent vassalage of King Euthydemus. The episode covers Antiochus’s march into the Hindu Kush, where he secured Indian elephants from Sophagasinus, and his naval expedition to the Persian Gulf, establishing influence in Gerha and Tylos. This successful Anabasis earned Antiochus the epithet "the Great" and set the stage for future conflicts with a vulnerable Egypt.
