Baldwin III of Jerusalem
In the Battle of Bosra (Spring 1147) a Crusader force commanded by King Baldwin III of Jerusalem fought an inconclusive running battle with Turkish forces from Damascus led by Mu'in ad-Din Unur 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. The thwarted Crusaders returned to their own territory. The Turks constantly harassed the Latin marching column but were unable to inflict a defeat on their enemies.
