To this proposal the German Secretary of State seemingly acquiesced, but, as usual, _nothing whatever was done_. [English "White Paper," No. 76.] It is true that on July 29 Sir Edward Grey was assured by the German Ambassador that the German Foreign Office was "endeavoring to make Vienna explain in a satisfactory form at St. Petersburg the scope and extension of Austrian proceedings in Servia," but again the communications which the German Foreign Office sent to Vienna on this point _have never yet been disclosed to the world_. [English "White Paper," No. 84.] In this same conference Sir Edward Grey "urged that the _German Government should suggest any method_ by which the influence of the four powers could be used together to prevent war between Austria and Russia. France agreed, Italy agreed. The whole idea of mediation or mediating influence was ready to be put into operation _by any method that Germany could suggest_ if mine were not acceptable. In fact, mediation was ready to come into operation by any method that Germany thought possible, if only Germany would 'press the button' in the interests of peace." [English "White Paper," No. 84.] The difficulty was, however, that Germany never "pressed the button," although obviously it would have been easy for her to do so, as the stronger and more influential member of the Double Alliance. On the same day the Austrian Government left a memorandum with Sir Edward Grey to the effect that Count Mensdorff said that the war with Servia must proceed. On the night of July 29 the British Ambassador at Berlin was informed that the German Foreign Office "_had not had time to send an answer yet_" to the proposal that Germany suggest the form of mediation, but that the question had been referred to the Austro-Hungarian Government with a request as to "what would satisfy them." [English "White Paper," No. 107.] On the following day the German Ambassador informed Sir Edward Grey that the German Government would endeavor to influence Austria, after taking Belgrade and Servian territory in the region of the frontier, to promise not to advance further, while the powers endeavored to arrange that Servia should give satisfaction sufficient to pacify Austria, but if Germany ever exercised any such pressure upon Vienna, _no evidence of it has ever been given to the world_. Certainly it was not very effective, and for the reasons mentioned it is impossible to conclude that the advice of Germany, if in good faith, would not have been followed by its weaker ally.
