Austria was supposed to be, and still is by some believed to have been, Germany's vassal State, and by menacing Serbia to have been doing Germany's dirty work. No evidence of this has been adduced; and the trouble with this idea of Austria's status is that it breaks down before the report of Sir M. de Bunsen, 1 September, 1914, that Austria finally yielded and agreed to accept all the proposals of the Powers for mediation between herself and Serbia. She made every concession. Russian mobilization, however, had begun on 25 July and become general four days later; and it was not stopped. Germany then gave notice that she would mobilize her army if Russian mobilization was not stopped in twelve hours; and also, knowing the terms of the Russian-French convention of 1892, she served notice on France, giving her eighteen hours to declare her position. Russia made no reply; France answered that she would do what she thought best in her own interest; and almost at the moment, on 1 August, when Germany ordered a general mobilization, Russian troops were over her border, the British fleet had been mobilized for a week in the North Sea, and British merchant ships were lying at Kronstadt, empty, to convey Russian troops from that port to the Pomeranian coast, in pursuance of the plan indicated by Lord Fisher in his autobiography, recently published. These matters are well summed up by Lord Loreburn, as follows: Serbia gave offence to the Austro-Hungarian Empire, cause of just offence, as our Ambassador frankly admits in his published dispatches. We [England] had no concern in that quarrel, as Sir Edward Grey says in terms. But Russia, the protectress of Serbia, came forward to prevent her being utterly humiliated by Austria. We were not concerned in that quarrel either, as Sir Edward also says. And then Russia called upon France under their treaty to help in the fight. France was not concerned in that quarrel any more than ourselves, as Sir Edward informs us. But France was bound by a Russian treaty, of which he did not know the terms, and then France called on us for help. We were tied by the relations which our Foreign Office had created, without apparently realizing that they had created them.
