At the Assemblée des Six-Comtés, on October 23, the patriot movement officially approves the Fils de la Liberté. The organization had two sections: a civil one, lead by Louis-Joseph Papineau and Edmund-Bailey O'Callaghan and a military one, lead by Thomas Storrow Brown.
The organization published a manifesto and chose a national anthem.
The organisation disapeared a little after the confrontation with the Doric Club on Novemver 6, following the order to arrest the leaders of the association including Papineau, O'Callaghan, Brown and Ouimet, on November 16.
