In the context of Occitan resistance and possibly linked to Raymond’s efforts to free himself from the chains of the Paris Treaty, two representatives of the Inquisition, William Arnald and Stephen de Saint-Thibéry, as well as their companions and retinue were murdered by about fifty men from Montségur and dispossessed faidits at Avignonet on 28 May 1242.[4] This event led to the decision to send a royal military expedition to eliminate the stronghold.
