ルノー・ド・シャティヨン
In 1156 Baldwin was forced to sign a treaty with Nur ad-Din. However, in the winter of 1157–1158 Baldwin led an expedition into Syria, where he besieged Shaizar. The expedition was forced to withdraw when a dispute arose between Thierry, Count of Flanders and Raynald of Châtillon, the new husband of Constance of Antioch, both of whom wanted Shaizar for themselves. Baldwin was, however, able to capture Harim, a former territory of Antioch, and in 1158 he defeated Nur ad-Din himself.
