The Battle of Inab, also called Battle of Ard al-Hâtim or Fons Muratus, was fought on 29 June 1149, during the Second Crusade. The Zengid army of the atabeg Nur al-Din Zengi destroyed the combined army of Prince Raymond of Antioch and the Assassins of Ali ibn-Wafa. The prince was killed, and the Principality of Antioch was subsequently pillaged and reduced in size as its eastern border was pushed west.
