In 1115, the Seljuk sultan Muhammad I Tapar sent Bursuq against Antioch. Jealous that their authority would be diminished if the Sultan's forces proved victorious, several Syrian Muslim princes allied themselves with the Latins.

Early on September 14, Roger received intelligence that his opponents were carelessly going into camp at the Tell Danith watering point, near Sarmin. He rapidly advanced and took Bursuq's army by complete surprise. As the Crusaders launched their attack, some Turkish soldiers were still straggling into the camp. Roger marshalled the Frankish army into left, center, and right divisions. Baldwin, Count of Edessa led the left wing while Prince Roger personally commanded the center. The Crusaders attacked in echelon with the left wing leading. On the Frankish right, the Turcopoles, who were employed as archers, were thrown back by a Seljuk counterattack. This disrupted the knights who faced tough fighting before repulsing their enemies on this part of the field. Roger decisively defeated Bursuq's army, ending the long campaign. At least 3,000 Turks were killed and many captured, along with property worth 300,000 bezants. Frankish losses were probably light. Roger's victory preserved the Crusader hold on Antioch.
