In a Paris newspaper Poincaré published in September, 1921, some strictly reserved documents on the questions of the military guarantees and the occupation of the left bank of the Rhine. He wished to get the credit of having stood firm when Clemenceau himself hesitated at the demand for an occupation of the left bank of the Rhine for even a longer period than fifteen years. He has published the letter he sent to Clemenceau to be shown to Wilson and Lloyd George and the latter's reply. He said that there must be no thought of giving up the occupation and renouncing a guarantee until every obligation in the treaty should have been carried out; he went so far as to claim that in occupation regarded as a guarantee of a credit representing an indemnity for damages, there is nothing contrary to the principles proclaimed by President Wilson and recognized by the Allies. Nor would it suffice even to have the faculty of reoccupation, because "this faculty" could never be a valid substitute for occupation. As regards the suggestion that a long occupation or one for an indeterminate period would cause bad feeling, M. Poincaré was convinced that this was an exaggeration. A short occupation causes more irritation on account of its arbitrary limit; everyone understands an occupation without other limit than the complete carrying out of the treaty. The longer the time that passes the better would become the relations between the German populations and the armies of occupation. Clemenceau communicated Poincaré's letter to Lloyd George. The British Prime Minister replied on May 6 in the clearest terms. In his eyes, forcing Germany to submit to the occupation of the Rhine and the Rhine Provinces for an unlimited period, was a provocation to renew the war in Europe.
