[6] Walter intervened in a conflict over the possession of Satalia between the Sultanate of Rum and an adventurer, Aldobrandino, on the latter's behalf, but the Seldjuks captured the town with the assistance of the local Greeks.

[8][7] In a letter sent to Pope Innocent III, Walter stated that Hugh had expelled him from Cyprus and confiscated his property without the judgement of the High Court.

[10] He gave his sister, Helvis, in marriage to Bohemond IV's rival, Raymond-Roupen, although she had been married to Odo of Dampierre (who was Walter of Montbéliard's kinsman).

[13] The pope also rebuked him for capturing John of Brienne's vassals whom Muslim ships had forced to land at Cyprus.

[13] In September 1217, Hugh joined King Andrew II of Hungary on the Fifth Crusade in raiding Muslim lands in Galilee.

On his return, he stopped in Tripoli to attend the wedding of his half-sister Melisende on 10 January 1218, but he became ill during the celebration and died.
