Career
Previously for many years the casteln of the crusader castle of Crac, Lorgne made improvements to Crac in the mid-13th century. An inscription records that he had a barbacane built, probably a reference to the zwinger system around the castle which can be dated to around 1250. Lorgne succeeded Hugues de Revel as Grand Master of the Knights Hospitaller in 1277, at a time when the situation of the Order in the Levant was desperate, and soon a truce for ten years was agreed.
In 1281 Lorgne wrote to Edward I of England and others to appeal for help, but little came.
Despite the truce, the Sultan Qala"un of Egypt began a siege of the castle of Margat on 17 April 1285, and on 25 May 1285 the castle surrendered. Within weeks Lorgne died, to be succeeded by Jean de Villiers.
