The 70,000-strong Palmyrene army, assembled on the plain of Emesa, nearly routed the Romans. In an initial thrill of victory they hastened their advance, breaking their lines and enabling the Roman infantry to attack their flank. The defeated Zenobia headed to her capital on the advice of her war council, leaving her treasury behind. In Palmyra, the queen prepared for a siege; Aurelian blockaded food-supply routes, and there were probably unsuccessful negotiations. According to the "Augustan History", Zenobia said that she would fight Aurelian with the help of her Persian allies; however, the story was probably fabricated and used by the emperor to link Zenobia to Rome's greatest enemy. If such an alliance existed, a much-larger frontier war would have erupted; however, no Persian army was sent. As the situation worsened, the queen left the city for Persia intending on seeking help from Palmyra's former enemy; according to Zosimus, she rode a "female camel, the fastest of its breed and faster than any horse".
