Location
Cause → Event → Consequence
The emir of Bosra and Salkhad, irritated with his Damascus overlord, invited the Crusaders to occupy both cities. This offer prompted King Baldwin III to march a Latin army toward Bosra, anticipating a peaceful transfer of the strategically important towns without armed resistance.
Before the Crusaders could take possession of Bosra, the emir's wife allowed a Damascene garrison into the city, denying the Latins their objective. Mu'in ad-Din Unur, reinforced by Nur ad-Din's forces from Mosul and Aleppo, then engaged the Crusader column. The subsequent battle was prolonged but neither side achieved a decisive victory.
Denied entry to Bosra, the Crusader force was compelled to withdraw through hostile territory under relentless Turkish harassment. Though the retreating column survived intact, the campaign failed entirely, and Crusader ambitions to extend control toward Damascus were checked without any territorial gain.
