from the white brotherhood folquet selected 500 men-at-arms and sent them to aid the albigensian crusade in besieging lavaur. the bishop even composed pro-crusade "sirventes" for the troops to sing. count raymond vii, however, forbade the citizens to go and tried to force folquet from the city. the white brotherhood did go, however, and the bishop eventually left as well, to join the siege at lavaur.
