John went on to attack Aleppo with the aid of Antioch and Edessa, and failed to capture it, with the Franks withdrawing their support when he moved on to capture Shaizar. John returned to Antioch ahead of his army and entered Antioch, only to be forced to leave when Joscelin II, Count of Edessa rallied the citizens to oust him. In 1142 John then returned but Raymond refused to submit and John was forced to return to Cilicia again due to the coming winter, to plan an attack the following season. However the emperor died on April 8, 1143.
