• First battle: Turkish victory[1][2] Kingdom of France The battles of Heraclea were a series of battles fought during the Crusade of 1101 between Crusaders led by William II, Count of Nevers and the Sultanate of Rum led by Kilij Arslan I.
[5][6][7] The French and Germans who headed east under the command of William II arrived at Istanbul early June 1101, where they headed to Konya through Nicomedia-Nicaea entering Seljuk lands near Aksehir.
As Kilij Arslan had heard of their marching, they evacuated cities, including Konya and destroyed the fields and water sources.
Kilij Arslan and Gazi Gümüshtigin waited for them to weaken.
When they saw the Crusaders running to a river, Kilij Arslan attacked and achieved a Turkish victory.
