They are joined by remnants of the German army which had previously taken heavy losses at Dorylaeum. Marching across Southwest Turkey and fight in a unsuccessful battle at Laodicea against the Turks on the border between Byzantine Empire and Seljuks of Rum (3-4 Jan 1148). On 8-Jan they battle again in the area of Mount Cadmus, where Turks ambush the main train of infantry and non-combatants because the main force is too far forwards. King Louis and his bodyguard of Templar Knights and Noblemen sallied forth in a classic example of chivalry to protect the poor and valiantly charged the Turks. Most of the knights were killed, including William, and Louis barely escaped with his life. His army arrives later at the coastal city of Adalia. The battle is recorded by Odo de Deuil, personal chaplain to Louis, in his book De Profectione - pp 68–127.

After he died without children in October 1159, she married Hamelin, half-brother of Henry II, who also became Earl of Warenne or Surrey. He took the de Warenne surname, and their descendants carried on the earldom.
