 Amalric and Shirkuh both besieged Bilbeis in 1164, but both withdrew due to Nur ad-Din's campaigns against Antioch, where Bohemond III of Antioch and Raymond III of Tripoli were defeated at the Battle of Harim.It seemed likely that Antioch itself would fall to Nur ad-Din, but he withdrew when Emperor Manuel sent a large Byzantine force to the area.Nur ad-Din sent Shirkuh back to Egypt in 1166, and Shawar again allied with Amalric, who was defeated at the Battle of al-Babein.
