 In 1146 Manuel assembled his army at the military base Lopadion and set out on a punitive expedition against Masud the Sultan of Rûm, who had been repeatedly violating the frontiers of the Empire in western Anatolia and Cilicia. There was no attempt at a systematic conquest of territory, but Manuel's army defeated the Turks at Acroënus, before capturing and destroying the fortified town of Philomelion, removing its remaining Christian population. The Byzantine forces reached Masud's capital, Konya, and ravaged the area around the city, but could not assault its walls. Among Manuel's motives for mounting this razzia there included a wish to be seen in the West as actively espousing the crusading ideal; Kinnamos also attributed to Manuel a desire to show off his martial prowess to his new bride. While on this campaign Manuel received a letter from Louis VII of France announcing his intention of leading an army to the relief of the crusader states.
