July 30th, 1 a.m.

My Ambassador has instructions to direct the attention of Your Government to the dangers and serious consequences of a mobilization; I have told You the same in my last telegram. Austria-Hungary has mobilized only against Servia, and only a part of her army. If Russia, as seems to be the case according to Your advice and that of Your Government, mobilizes against Austria-Hungary, the part of the mediator with which You have entrusted me in such friendly manner and which I have accepted upon Your express desire, is threatened if not made impossible. The entire weight of decision now rests upon Your shoulders, You have to bear the responsibility for war or peace.

signed: Wilhelm.

V. The Czar to His Majesty.

Peterhof, July 30th, 1914, 1.20 p.m.

I thank You from my heart for Your quick reply. I am sending to-night Tatisheft (Russian honorary aide to the Kaiser) with instructions. The military measures now taking form were decided upon five days ago, and for the reason of defence against the preparations of Austria. I hope with all my heart that these measures will not influence in any manner Your position as mediator which I appraise very highly. We need Your strong pressure upon Austria so that an understanding can be arrived at with us.

Nicolas.
