At 1 am on 13 Vendémiaire (5 October), Bonaparte overrode Barras, who was content to let him do as he wished.[citation needed] Bonaparte ordered Joachim Murat, a sous-lieutenant in the 12ème Régiment de Chasseurs à Cheval, to ride to the plain of Sablons and to return with the 40 cannons which Menou had indicated were located there. Murat's squadron retrieved the cannons before the Royalists arrived and Bonaparte organised their arrangement, placing them in commanding areas with effective fields of fire.
