Roger defeated Bursuq ibn Bursuq in 1115 at the Battle of Tell Danith. With Joscelin I of Edessa, Roger put enough military pressure on Aleppo that the city allied with Ortoqid emir Ilghazi in 1118.[3] Ilghazi invaded the Principality in 1119, and despite the urging of the Patriarch, Roger did not wait for reinforcements from Jerusalem or Tripoli.[4] At the ensuing Battle of Ager Sanguinis he had 700 knights and 3000 foot soldiers, including 500 Armenian cavalry, but nearly all were killed, including Roger himself.
