On July 21 M. Jules Cambon, French Ambassador at Berlin, reported to M. Bienvenu-Martin, Acting Minister for Foreign Affairs at Paris, that M. Yovanovitch, Serbian Minister to Germany, had declared to the German Government that Serbia was willing to entertain Austria's requirements arising out of the Sarajevo outrage, provided that she asked only for
"judicial cooperation in the punishment and prevention of political crimes, but that he was charged to warn the German Government that it would be dangerous to attempt, through that investigation, to lower the prestige of Serbia.
"M. Browniewsky, Russian Chargé d'Affaires at Berlin, mentioned this subject to Herr von Jagow, German Secretary of State. Von Jagow said that he supposed the German Government now had full knowledge of the note prepared by Austria, and were therefore willing to give the assurance that the Austro-Serbian difficulties would be localized. The Secretary of State protested that he was in complete ignorance of the contents of that note, and expressed himself in the same way to me. I could not help showing my astonishment at a statement which agreed so little with what circumstances lead one to expect.
"I have also been assured that from now on the preliminary notices for mobilization, the object of which is to place Germany in a kind of 'attention' attitude in times of tension, have been sent out here to those classes which would receive them in similar circumstances. That is a measure to which the Germans, constituted as they are, can have recourse without indiscretion and without exciting the people. It is not a sensational measure, and is not necessarily followed by full mobilization, as we have already seen, but it is none the less significant."
On the same day, July 21, 1914, M. Bienvenu-Martin, Acting Minister for Foreign Affairs at Paris, notified the French Legations at London, St. Petersburg, Vienna, and Rome that the Berlin Bourse was extremely weak on the 20th, probably on account of anxiety over the Serbian question, and that M. Cambon, French Ambassador at Berlin, had grave reason that Germany would support Austria-Hungary in her contemplated démarche at Belgrade without seeking to play the part of mediator.
On the same day, July 21, 1914, Baron Giesl von Gieslingen, Austro-Hungarian Minister at Belgrade, wrote a long letter to Count Berchtold, Minister for Foreign Affairs at Vienna, reviewing the situation. Most of his statements have been given in more moderate language in the preceding correspondence. He describes how the relations between Serbia and Austria-Hungary have been "poisoned" by Serbian national aspirations, due to the great Serbian propaganda (carried on in Austria-Hungary as well as in Serbia), and to Serbian success in the Balkan wars. This chauvinism has increased to a paroxysm, bordering on insanity. The policy is to separate from Austria-Hungary the southern Slav provinces, and so abolish the Dual Monarchy as a great power. Bosnia and Herzegovina are expected to revolt, and the Slav regiments in the Austro-Hungarian army to mutiny. Out of the ruins will be builded the great Serbian Empire, and that in the immediate future.
Serbian newspapers without fear of reprimand discuss the decrepitude of the Dual Monarchy and insult her officials, and even "the exalted person of our ruler." The press is the educator of the Serbian people; it promoted the great Serbian propaganda, from which sprang the crime of Sarajevo. Political parties and governmental policy are wholly subservient to it. Its accusations that the sudden death of the Russian Minister, Dr. Hartwig, was due to poison are on the verge of insanity—the London "Times" called them ravings. The people, in gratitude for the past, and in anxiety for the future, outbid one another in servility to Russia. They despise Austria-Hungary as powerless, for internal and external reasons. The serious words of our statesmen are regarded as "bluff."
"This picture leads up to the conclusion that a reckoning with Serbia, a war for the position of the [Dual] Monarchy as a great power, even for its existence as such, cannot be permanently avoided.
"If we delay in clearing up our relations with Serbia we shall share the responsibility for the difficulties and the unfavorable situation in any future war which must, however, sooner or later be carried through....
"Should we therefore ... put forward far-reaching requirements joined to effective control—for this alone could clear the Augean stable of great Serbian intrigues—then all possible consequences must be considered, and from the beginning there must be a strong and firm determination to carry through the matter to the end.
