ration in the hands of England, France, Germany, and Italy--the
four Powers whom Sir Edward Grey had suggested as possible mediators.

On the day on which Russia made this suggestion, July 25, the Servian
Government replied to the Austrian note, conceding part of the Austrian
demands, and announcing its readiness to accept, on the other points,
the arbitration of the Hague Tribunal or of the Great Powers. The
Austrian Government found the Servian note unsatisfactory, and
criticized its details in an official memorandum.[32] The
Austro-Hungarian Minister left Belgrade on July 25; on July 26 a part of
the Austro-Hungarian army was mobilized; and on July 28 Austria-Hungary
declared war on Servia.

Sir Edward Grey had from the first declined to 'announce England's
solidarity' with Russia and France on the Servian question. On and after
July 26 he was taking active steps to bring about the mediation, between
Austria-Hungary and Servia, of four Powers (Italy, Germany, France,
England). To this mediation Russia had already agreed, July 25; and
Italy and France were ready to co-operate with England.[33] Germany,
however, made difficulties on the ground that anything like formal
intervention would be impracticable, unless both Austria and Russia
consented to it.[34] Russia had already (July 25) prepared the ukase
ordering mobilization,[35] but had not yet issued it; on July 27 the
Russian Foreign Minister announced his readiness to make the Servian
question the subject of direct conversations with Vienna.[36] This offer
was at first declined by the Austro-Hungarian Government, but
subsequently accepted; and conversations were actually in progress
between the representatives of the two Powers as late as August 1.[37]

No doubt the hesitation of Austria was due to the fact that, on July 28,
the Russian Government warned Germany of the mobilization of the
southern military districts of Russia, to be publicly proclaimed on July
29.[38] Austria replied to this intimation by offering assurances that
she would respect the integrity and independence of Servia;[39] these
assurances, considered inadequate by the Russian Government, seem to
have been the subject of the last conversations between Russia and
Austria-Hungary.

Russia persisted that Germany was the real obstacle to a friendly
settlement; and this conviction was not affected by the appeals for
peace which the Kaiser telegraphed to the Tsar on July 28, July 29, and
July 31.[
