They were aware of that Kilij Arslan was about: he had returned to the fray after the defeat of Nicaea, with an army of 6,000-7,000 mounted man, including his new allies, the Danishmend Turks."
1 2 Bennett, The Hutchinson Dictionary of Ancient & Medieval Warfare, p. 103 "Following their successful siege of Nicaea in 1097, the crusaders split into two columns to aid foraging. The vanguard under Bohemond was attacked at Bozüyük. Sultan Kilij Arslan led 7,000-8,000 Seljuk mounted archers in an ambush, throwing the crusaders into confusion."
1 2 John France, Victory in the East, tr. 181 "Casualties appear to have been heavy although how far we can regard Albert's 4,000 Christians and 3.000 Turks as precise figures is a different matter."
