 This period was called the "Guerre de Cabaret" (War of Cabaret).The Lastours castles held out as a centre of opposition to the conquests of Simon de Montfort, who determined to wipe them out.In this, he was bound to fail, having to launch simultaneous attacks on three castles protected by sheer rockfaces and defended by a nobleman who, though not a Cathar, was aware of the importance of the campaign de Montfort was waging against his suzerain, the viscount of Carcassonne.
