By early November,[2] Tenagino Probus was alerted of the events, quickly returned, assembled an army, expelled the Palmyrenes and regained Alexandria, only for Zabdas to promptly return to Egypt.[10] Zabdas quickly regained Alexandria, where Zenobia and the Palmyrenes seemed to have had local support, and Probus fled south.[2] The last battle was at the Babylon Fortress, where Tenagino Probus took refuge. Although the Romans had the upper hand;[5] Timagenes, with his knowledge of the land, ambushed the Roman rear, capturing the fortress. Tenagino Probus ended up committing suicide.
