Post haec Palmyram iter flexit, ut ea oppugnata laborum terminus fieret. sed in itinere a latronibus Syris male accepto frequenter exercitu multa perpessus est et in obsidione usque ad ictum sagittae periclitatus est.
Translation :
After this he directed his march toward Palmyra, in order that, by storming it, he might put an end to his labours. But frequently on the march his army met with a hostile reception from the brigands of Syria, and after suffering many mishaps he incurred great danger during the siege, being even wounded by an arrow.
