46 - Dorylaeum

Following the fall of İznik, Kılıç Arslan regroups his forces, belatedly calling for aid from across Turkish Anatolia.  The Crusaders depart from İznik and begin their march to the Holy Land.  Kılıç Arslan springs an ambush near Eskişehir on the Plains of Dorylaeum, leading to disaster yet again.  In the aftermath of the great defeat, the Sword Lion is unable to oppose the Crusaders head on, but the war continues as a wide swathe of destruction is cut across Anatolia - and the seeds of a transformed Sultanate of Rum are planted.
