Painfully conscious of de Gaulle's mistrust of him, aware of the frustration of his own chef-d'oeuvre, as Challe left Algiers his overflowing cup of gall contained one final ingredient. During the crisis of "Barricades Week" he had been induced to give those various assurances to the men under him that they were "fighting in order that Algeria shall remain definitively French", and that de Gaulle had promised him "there will be no negotiations with the F.L.N." Over the course of the next few months he was to come to believe that he had been permitted, if not actively encouraged, by de Gaulle to perjure himself.
