I love this one. I think it was from a crusade in Southern France (it wasn't part of France then) against the Albigensian from 1209 to 1229. The crusade was startet by pope Innosence III with the aid of French king Phillip II. Many catholic citizens fought side by side with the heretic. When Bezier, the first town was conquered, the General sked the ambassader of the pope, abbot Arnaud-Amaury asked how to select the heteric. He answered: Caedite eos! Novit enim Dominus qui sunt eius - kill them all, God will find his own.
