 On the evening of 26 March , Jourdan arranged for the abandonment of the positions in Engen and Stockach . Saint Cyr had already withdrawn along the Danube , after his and Vandamme 's assaults on the Austrian right failed , and was working his way west toward the Black Forest . Inexplicably , at least at the time , the Austrians failed to pursue the retreating French ; instead of pursuing the French , Charles ordered his army into cantonments at Stockach and Engen , as far south as <unk> . The Aulic Council , in establishing a plan of battle , had forbidden his approach to the Rhine until Switzerland was also cleared of the French army ; Charles simply held his ground .
