Aurelian, learning about Zenobia's departure, sent a contingent which captured the queen before she could cross the Euphrates to Persia; Palmyra capitulated soon after news of Zenobia's captivity reached the city in August 272. Aurelian sent the queen and her son to Emesa for trial, followed by most of Palmyra's court elite (including Longinus). According to the "Augustan History" and Zosimus, Zenobia blamed her actions on her advisers; however, there are no contemporary sources describing the trial, only later hostile Roman ones. The queen's reported cowardice in defeat was probably Aurelian's propaganda; it benefited the emperor to paint Zenobia as selfish and traitorous, discouraging the Palmyrenes from hailing her as a hero. Although Aurelian had most of his prisoners executed, he spared the queen and her son to parade her in his planned triumph.
