All the Allies were ready to give France every military guarantee against any unjust aggression by Germany, but France wanted in addition the occupation of the left bank of the Rhine. It was a very delicate matter, and the notes presented to the Conference by Great Britain on March 26 and April 2, by the United States on March 28 and April 12, show how embarrassed the two Governments were in considering a question which France regarded as essential for her future. It has to be added that the action of Marshal Foch in this matter was not entirely constitutional. He claimed that, independently of nationality, France and Belgium have the right to look on the Rhine as the indispensable frontier for the nations of the west of Europe, et par là, de la civilisation. Neither Lloyd George nor Wilson could swallow the argument of the Rhine a frontier between the civilization of France and Belgium, all civilization indeed, and Germany.
In the treaty the occupation of the left bank of the Rhine and the bridgeheads by the allied and associated powers for fifteen years was introduced as a compromise. Such districts will be evacuated by degrees every five years if Germany shall have faithfully carried out the terms of the treaty. Now the conditions of the treaty are in large measure impossible of execution, and in consequence no execution of them can ever be described as faithful. Further, the occupying troops are paid by Germany. It follows that the conception of the occupation of the left bank of the Rhine was of a fact of unlimited duration. The harm that would result from the occupation was pointed out at the Conference by the American representatives and even more strongly by the English. What was the use of it, they asked, if the German army were reduced to 100,000 men? M. Tardieu himself tells the story of all the efforts made, especially by Lloyd George and Bonar Law, to prevent the blunder which later on was endorsed in the treaty as Article 428. Lloyd George went so far as to complain of political intrigues for creating disorder on the Rhine. But Clemenceau took care to put the question in such a form that no discussion was possible. In the matter of the occupation, he said to the English, you do not understand the French point of view. You live in an island with the sea as defence, we on the continent with a bad frontier. We do not look for an attack by Germany but for systematic refusal to carry out the terms of the treaty. Never was there a treaty with so many clauses, with, consequently, so many opportunities for evasion. Against that risk the material guarantee of occupation is necessary. There are two methods in direct contrast: En Angleterre on croit que le moyen d'y réussir est de faire des concessions. En France nous croyons que c'est de brusquer.
On March 14 Lloyd George and Wilson had offered France the fullest military guarantee in place of the occupation of the left bank of the Rhine. France wanted, and in fact got, the occupation as well as the alliances. "Notre but?" says Tardieu. "Sceller la garantie offerte, mais y ajouter l'occupation." Outside the Versailles Treaty the United States and Great Britain had made several treaties of alliance with France for the event of unprovoked aggression by Germany. Later on the French-English Treaty was approved by the House of Commons, the French-American underwent the same fate as the Versailles Treaty. But the treaty with Great Britain fell through also on account of the provision that it should come into force simultaneously with the American Treaty.
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.
During the Conference France put forward some proposals the aim of which was nothing less than to split up Germany. A typical example is the memorandum presented by the French delegation claiming the annexation of the Saar territory. This is completely German; in the six hundred and fifty thousand inhabitants before the War there were not a hundred French. Not a word had ever been said about annexation of the Saar either in Government pronouncements or in any vote in the French Parliament, nor had it been discussed by any political party. No one had ever suggested such annexation, which certainly was a far more serious thing than the annexation of Alsace-Lorraine to Germany, as there was considerable German population in Alsace-Lorraine. There was no French population at all in the Saar, and the territory in question could not even be claimed for military reasons but only for its economic resources. Reasons of history could not count, for they were all in Germany's favour. Nevertheless the request was put forward as a matter of sentiment. Had not the Saar belonged in other days entirely or in part to France? Politics and economics are not everything, said Clemenceau; history also has great value. For the United States a hundred and twenty years are a long time; for France they count little. Material reparations are not enough, there must be moral reparations too, and the conception of France cannot be the same as that of her Allies. The desire for the Saar responded, according to Clemenceau, to a need of moral reparation. On this point, too, the extreme French claim was modified. The Saar mines were given to France, not provisionally as a matter of reparations, but permanently with full right of possession and full guarantees for their working. For fifteen years from the date of the treaty the government of the territory was put in the hands of the League of Nations as trustee; after fifteen years the population, entirely German, should be called to decide under what government they desired to live. In other words, in a purely German country, which no one in France had ever claimed, of which no one in France had ever spoken during the War, the most important property was handed to a conquering State, the country was put under the administration of the conquerors (which is what the League of Nations actually is at present), and after fifteen years of torment the population is to be put through a plebiscite. Meanwhile the French douane rules in the Saar.
It was open to the treaty to adopt or not to adopt the system of plebiscites. When it was a case of handing over great masses of German populations, a plebiscite was imperative—at any rate, where any doubt existed, and the more so in concessions which formed no part of the War aims and were not found in any pronouncement of the Allies. On the other hand, in all cessions of German territory to Poland and Bohemia, no mention is made of a plebiscite because it was a question of military necessity or of lands which had been historically victims of Germany. But only for Schleswig, Upper Silesia, Marienwerder, Allenstein, Klagenfurth and the Saar were plebiscites laid down—and with the exception that the plebiscite itself, when, as in the case of Upper Silesia, it resulted in favour of Germany, was not regarded as conclusive.
But where the most extreme views clashed was in the matter of reparations and the indemnity to be claimed from the enemy.
We have already seen that the theory of reparation for damage found its way incidentally, even before the treaty was considered, into the armistice terms. No word had been said previously of claiming from the conquered enemy anything beyond restoration of devastated territories, but after the War another theory was produced. If Germany and her allies are solely responsible for the War, they must pay the whole cost of the War: damage to property, persons and war works. When damage has been done, he who has done the wrong must make reparation for it to the utmost limit of his resources.
