In 1144 the Crusader state of Edessa was besieged in a border war that threatened its survival. Queen Melisende responded by sending an army led by constable Manasses of Hierges, Philip of Milly, and Elinand of Bures. Raymond of Antioch ignored the call for help, as his army was already occupied against the Byzantine Empire in Cilicia. Despite Melisende's army, Edessa fell.
