Battle of Dorylaeum (1147)
The second Battle of Dorylaeum took place at Dorylaeum on October 25, 1147, during the Second Crusade. Conrad III, running out of provisions, stopped there to rest, and his army of 20,000 men was badly defeated by the Seljuk Turks led by Mesud I. The Germans were unable to continue the Crusade, and Conrad made his way (with his remaining army of 2,000 men) to the army led by Louis VII of France, although the Crusade eventually failed completely.
