"he treaty ...provided for a fifteen-year occupation of the Rhineland, with retreats every five years. Such a guarantee, I said without mincing my words, was ‘from the military point of view, null; it will merely be an increase of work for the Allied occupation.’ I went on to say that whereas the treaty was non-existent as promoter of our security, it was distinctly bad for reparations. ... I asked who would be judge of the situation if we sought to reoccupy the Rhineland because of an infringement of terms by Germany. The Commission for Reparations would not suffice, I said. It cannot be denied that I was right on this point."

“If France has a firm hold of the Rhine, she may be at rest, for she can be sure of reparations and security; without the Rhine she has neither. All that may be offered or given in exchange is valueless, illusory, empty. That is the position I took up immediately. We must have the Rhine line; we want nothing more and will take nothing less.”

“Germany is about to join . It will be alleged that she conforms in spirit to that of the League. If you hope that she will desire to maintain the frontiers forced on her, which she has never acknowledged in her heart, and which, bluntly speaking, she loathes and yearns to destroy—if you can hope that, you must have more than your share of naïveté.”

“To be disciplined does not mean being silent, abstaining, or doing only what one thinks one may undertake without risk; it is not the art of eluding responsibility; it means acting in compliance with orders received, and therefore finding in one's own mind, by effort and reflection, the possibility to carry out such orders. It also means finding in one's own will the energy to face the risks involved in execution.”

“This absence of similarity among military questions naturally brings out the inability of memory to solve them; also the sterility of invariable forms, such as figures, geometrical drawings , plans , etc. One only right solution imposes itself : namely, the application, varying according to circumstances, of fixed principles.”
