I said to the German Ambassador that, as long as there was only a dispute between Austria and Serbia alone, I did not feel entitled to intervene; but that, directly it was a matter between Austria and Russia, it became a question of the peace of Europe, which concerned us all.
I had furthermore spoken on the assumption that Russia would mobilize, whereas the assumption of the German Government had hitherto been, officially, that Serbia would receive no support; and what I had said must influence the German Government to take the matter seriously.
