The Battle of Bosra was a lengthy and ultimately inconclusive battle fought in the spring of 1147 during the Second Crusade, between a Crusader force commanded by King Baldwin III of Jerusalem and Turkish forces from Damascus led by Mu'in ad-Din Unur, who was aided by Nur ad-Din's contingent from Mosul and Aleppo. Irritated by his Damascus overlord, the emir of Bosra and Salkhad invited the Crusaders to occupy the two places. Before the Latin army could take possession of Bosra, the emir's wife allowed a Damascene garrison into the city, and the thwarted Crusaders were forced to retreat via a grueling march through enemy territory. The Turks constantly harassed the retreating Latin column but were unable to inflict a defeat on their enemies.
