Belgian opinion became alarmed at the menace to the Belgian Congo. On July 21, Sir Edward Grey spoke very clearly and Mr. Lloyd George declared the same evening that war was better than peace with humiliation. He added that the safety of Great Britain’s commerce overseas was no question of party, and that the national honour was at stake. England to a man showed that it was prepared to back France against the German demands. The Franco-British Entente Cordiale, which had been asleep for a fortnight, became more wideawake than ever. Mr. Asquith described the situation as “extremely difficult.”

The situation of the German Government in view of this awakening of public opinion seemed to have two issues only. Either an ultimatum in reply to the French Government’s refusal to submit, or the acceptance in principle of a rectification of the Congo-Cameroon frontier and the granting to France of sufficient authority to cope with the threat of anarchy in Morocco. An ultimatum would have meant war, and Germany would have appeared to be the aggressor. The abandonment of her claims was an awkward step to take.

It seems, however, likely that Germany would have taken it, if she had not believed that secret negotiations with prominent men in France were possible. The conduct of these secret negotiations without the knowledge of Monsieur de Selves is the reason which induced Monsieur Clemenceau to say later that Monsieur Caillaux ought to be impeached by the high court for high treason. It is very difficult to state with absolute precision exactly what these negotiations were. According to Monsieur Caillaux the first mention of the Belgian Congo was made by Monsieur von Lancken, but there seems to be every reason to believe that Monsieur Caillaux lost his head a little and introduced the question himself. If this be so Monsieur Caillaux committed a grave fault in tactics, and it appears certain that the German Government considered Monsieur Caillaux an easier person to deal with in these matters than his Foreign Minister. Monsieur Caillaux’s opinions on the value to France of British help were certainly very well known—too well known in fact—in the German Embassy in Paris. Monsieur Caillaux was believed by the German Foreign Office to put no faith in eventual help in France’s need from the British army. This anxiety on the part Monsieur Caillaux, and the knowledge of this anxiety in German official quarters, enabled the Wilhelmstrasse to exercise indirect pressure.

It is not known exactly, and I do not suppose ever will be known exactly, what negotiations were carried on with Herr von Gwinner of the Deutsche Bank and with or through Sir Ernest Cassel. But on July 28, the German Government was convinced that Monsieur Caillaux was ready to treat. On that date, when Monsieur Jules Cambon asked the German Foreign Minister whether Germany were not ready to find some means of transaction other than the mutilation of the French Congo, Herr von Kiderlen Waechter replied: “No, the question is no longer what it was.” This reply is noted in the French Yellow Book.

Monsieur Caillaux’s personal interference in the negotiations undoubtedly allowed the German Foreign Office time to breathe, and the Cabinet of Berlin took care to fix her claims on the Congo in such a way as not to justify British alarm, and to offer with one hand what it withdrew with the other, in Morocco. These negotiations lasted fully three months, during which time it is not too much to say that France and Germany, or better still France, Germany and Europe generally, were on the very verge of war more than once.

Rumour has been busy with sidelights on the negotiations which took place, and not the least interesting of these sidelights is afforded by the telegram which is said to have passed between Berlin and Paris, between the Wilhelmstrasse and the German Embassy: “Do not waste time in discussion with De Selves or Cambon. We can get more out of Caillaux.” I do not know whether these are the exact words of the famous telegram, but they are certainly the gist of its meaning. It may be taken as certain that the telegram was sent and received, that Monsieur de Selves obtained possession of it, and that Monsieur Calmette would have published it in the Figaro in the course of his campaign against Monsieur Caillaux if he had not been induced to refrain from so doing on patriotic grounds. Several people have seen and read this telegram. After the death of Gaston Calmette it was found in his pocket book with a bullet-hole through it, and handed over, by the brothers of the dead man, to Monsieur Raymond Poincaré in person, for safe keeping. It is the telegram which is currently known as “the green document” because of the paper on which it was transcribed. The French Foreign Office was in possession at this time of the cipher which was used for telegraphic communications between Paris and Berlin by the Wilhelmstrasse and the German Embassy in Paris. Monsieur de Selves knew therefore that “the green document” had been sent, knew its contents, and had a very stormy interview with Monsieur Caillaux, his Prime Minister, in consequence.

The interview was a dramatic one. Monsieur de Selves when he learned of “the green document” consulted Monsieur Clemenceau and Monsieur Briand. He spoke of it, I believe, in other quarters also, and eventually he asked President Fallières to confront him with Monsieur Caillaux so that the discussion on Monsieur Caillaux’s interference with the negotiations between the French and German Foreign Offices should take place in the presence of the President of the Republic. Monsieur Caillaux, in a fury of indignation, declared to Monsieur Fallières that there was no truth in the insinuation contained in the message, and went straight to the German Embassy to ask what they meant there by the assertion made in “the green document.” The obvious answer to this ill-considered step was an immediate change in the Wilhelmstrasse cipher. Monsieur Caillaux, by his fit of anger and his imprudence, had lost to his Government a valuable source of information.

There is no need here to give the details of the agreement with Germany which was concluded not very long after the events just mentioned. There can be little doubt, I think, that France might have made a much better bargain if Monsieur Caillaux had been a little cooler and shown less unwisdom. On November 6 Monsieur Caillaux in a speech to his constituents at Saint Calais defended his policy. A week after this speech the German treaty was discussed for a full week in the Chamber, and accepted on November 21. During this week’s debate Monsieur Caillaux was attacked with some vivacity, and Monsieur de Selves’ attitude gave cause for much excitement. On January 9, 1912, the Senate sitting in committee discussed the Franco-German treaty. In the course of this discussion Monsieur Caillaux, the Prime Minister, explained the conditions under which the negotiations for Franco-German collaboration in the N’Goko Sanga Company and the Congo Cameroon Railway had fallen through, and made this declaration: “An attempt has been made in the Press and elsewhere to establish the story that negotiations with Germany were carried on outside the negotiations of the Ministry for Foreign Affairs. I give my word of honour that there were never any such negotiations beyond those carried on through diplomatic channels.

This declaration was listened to in deep silence, which Monsieur Clemenceau broke. “Will the Minister for Foreign Affairs,” said Monsieur Clemenceau, “state whether documents are in existence showing that our Ambassador in Berlin complained of the intrusion of certain people into the diplomatic negotiations between France and Germany?”

The members of the senatorial commission all turned to Monsieur de Selves, but Monsieur de Selves remained silent. Monsieur Caillaux, who had sat down, jumped up again, but Monsieur Clemenceau prevented him from speaking. “I am not addressing myself to you, Monsieur le President du Conseil,” he said. “I put this question to the Minister for Foreign Affairs.”
