Career
Captured by the Catalan Company, he accepted the post of rector and marshal of the Company (rector et marescalcus universitatis) after Boniface of Verona declined lieutenant Deslaur was the agent through which Walter had first hired the Catalan Company for six months in 1310. Deslaur remained with Walter even after he tried to expel the Catalans.
Following Halmyros, the Catalans granted Deslaur the fief of Salona (called "Louisiana Sola" by Ramon Muntaner) and the hand in marriage of the widow of the lord of Salona, Thomas III of Autremencourt.
Deslaur, however, proved ineffective as a defender of the Catalan conquests. Frederick sent Berenguer Estañol to act as Manfred"s vicar general and Deslaur stepped down from his post as leader of the Company and duke of Athens, retiring to his castle at Salona, which he either escheated, or he was forced to relinquish, to Alfonso Fadrique around 1318.
