Battle of DorylaeumDorylaeum, Eskişehir, Turkey
The crusaders had left Nicaea on 26 June 1097, with a deep distrust of the Byzantines, who had taken the city without their knowledge after the lengthy siege of Nicaea. In order to simplify the problem of supplies, the Crusader army had split into two groups; the weaker led by Bohemond of Taranto, his nephew Tancred, Robert Curthose, Robert of Flanders, and the Byzantine general Tatikios in the vanguard, and Godfrey of Bouillon, his brother Baldwin of Boulogne, Raymond IV of Toulouse, Stephen II of Blois, and Hugh of Vermandois in the rear.
On 29 June, they learnt that the Turks were planning an ambush near Dorylaeum (Bohemond noticed that his army was being shadowed by Turkish scouts). The Turkish force, consisting of Kilij Arslan and his ally Hasan of Cappadocia, along with help from the Danishmends, led by the Turkish prince Gazi Gümüshtigin. Contemporary figures place the number of Turks as between 25,000–30,000, with more recent estimates are between 6,000 and 8,000 men.
The Battle of Dorylaeum took place during the First Crusade on 1 July 1097, between the Seljuk Turks and the Crusaders, near the city of Dorylaeum in Anatolia. Despite the Turkish forces of Kilij Arslan almost destroying the Crusader contingent of Bohemond, other Crusaders arrived just in time for a very close victory.
The crusaders did indeed become rich, at least for a short time, after capturing Kilij Arslan's treasury. The Turks fled and Arslan turned to other concerns in his eastern territory.
