Widely varying figures from different sources were given for the Kara-Khitan forces, ranging from 20,000[2] to 300,000,[3] and 700,000,[4] while the Seljuk forces ranged from 70,000 to 100,000. The Kara-Khitans were also said to have been given a reinforcement of 30,000–50,000 Karluk horsemen.[10] While many Muslim sources suggested that the Kara-Khitan forces greatly outnumbered the Seljuks, some contemporary Muslim authors also reported that the battle was fought between forces of equal size.[4]
