In 1143, the Danishmendid Sultan Melik Mehmed Gazi died, which resulted in a civil war between Melik Zünnun and his uncles Yağıbasan and Ayn el-Devle, which ended in the division of the Danishmend lands between them, with each three ruling their own territory.
The Seljuk Sultan Mesud I decided to take advantage of the civil war and invade the Danishmendids.
Although Manuel was wounded in the heel, he burned the town and took the remaining Christian population there,[9][10] Manuel then headed for Iconium, Alarmed by Byzantine victories, Mesud divided his forces into 4 groups, one to protect the capital, the second stationed at Lake Tatta to ambush the Byzantines behind, the third at Outskirts of city and the last to slow down the incoming Byzantines, during their march, the Byzantines were still being ambushed by the Turks which inflicted losses on the Byzantines, they finally arrived at Ikonion and began ravaging the Outskirts of the capital, the Seljuks could only skirmish them from the walls, Manuel then besieged and surrounded the city, but failed to capture it, he prolonged the siege, however, he heard the news of an upcoming Crusade to the east, which prompted him to retreat.
[11][12][13] During the retreat, he passed some of the rugged paths that caused the Byzantine march to be slow and unorganized, and for that, it was a chance for the Seljuks; they ambushed the Byzantines and inflicted heavy losses on the center of the army, which killed the commander Kritopolos.
Manuel successfully reached safety after having great difficulty dealing with the Seljuk ambush;[14][15] according to an anonymous Seljuk-nama, it claims that the Byzantines lost as many as 20,000 men.
