After his victory, Zabdas marched south along the Jordan Valley and apparently met little opposition. There is evidence that Petra was attacked by a small contingent which penetrated the region. Arabia and Judaea were eventually subdued. Palmyrene dominance of Arabia is confirmed by many milestones bearing Vaballathus' name. Syrian subjugation required less effort because Zenobia had substantial support there, particularly in Antioch, Syria's traditional capital. The invasion of Arabia coincided with the cessation of coin production in Claudius' name by the Antiochean mint, indicating that Zenobia had begun tightening her grip on Syria. By November 270, the mint began issuing coinage in Vaballathus' name.
