Nay, even before the reply from Vienna regarding the Anglo-German mediation whose tendencies and basis must have been known in St. Petersburg, could possibly have been received in Berlin, Russia ordered a general mobilization. [Sidenote: see exhibits 18, 20, 21, 22, 23.] During the same days, there took place between His Majesty the Kaiser, and Czar Nicolas an exchange of telegrams in which His Majesty called the attention of the Czar to the menacing character of the Russian mobilization during the continuance of his own mediating activities. On July 31st, the Czar directed the following telegram to His Majesty the Kaiser: "I thank You cordially for Your mediation which permits the hope that everything may yet end peaceably. It is technically impossible to discontinue our military preparations which have been made necessary by the Austrian mobilization. It is far from us to want war. As long as the negotiations between Austria and Servia continue, my troops will undertake no provocative action. I give You my solemn word thereon. I confide with all my faith in the grace of God, and I hope for the success of Your mediation in Vienna for the welfare of our countries and the peace of Europe. "Your cordially devoted "Nicolas." This telegram of the Czar crossed with the following, sent by H.M. the Kaiser, also on July 31st, at 2 p.m.: "Upon Your appeal to my friendship and Your request for my aid I have engaged in mediation between Your Government and the Government of Austria-Hungary. While this action was taking place, Your troops were being mobilized against my ally Austria-Hungary, whereby, as I have already communicated to You, my mediation has become almost illusory. In spite of this, I have continued it, and now I receive reliable news that serious preparations for war are going on on my eastern frontier. The responsibility for the security of my country forces me to measures of defence. I have gone to the extreme limit of the possible in my efforts for the preservation of the peace of the world. It is not I who bear the responsibility for the misfortune which now threatens the entire civilized world. It rests in Your hand to avert it. No one threatens the honor and peace of Russia which might well have awaited the success of my mediation. The friendship for You and Your country, bequeathed to me by my grand-father on his deathbed, has always been sacred to me, and I have stood faithfully by Russia while it was in serious affliction, especially during its last war. The peace of Europe can still be preserved by You if Russia decides to discontinue those military preparations which menace Germany and Austria-Hungary."
