This statement is not very convincing. States do not usually bind themselves in the way just described, unless they have some advantageous agreement with the Power which has the first claim on their alliance. It is noteworthy, however, that the Duc de Gramont, in the correspondence alluded to above, admits that, as Ambassador and as Foreign Minister of France, he never had to claim the support of Austria in the war with Prussia[12].

How are we to reconcile these statements with the undoubted fact that the Emperor Napoleon certainly expected help from Austria and also from Italy? The solution of the riddle seems to be that Napoleon, as also Francis Joseph and Victor Emmanuel, kept their Foreign Ministers in the dark on many questions of high policy, which they transacted either by private letters among themselves, or through military men who had their confidence. The French and Italian sovereigns certainly employed these methods, the latter because he was far more French in sympathy than his Ministers.
As far back as the year 1868, Victor Emmanuel made overtures to Napoleon with a view to alliance, the chief aim of which, from his standpoint, was to secure the evacuation of Rome by the French troops, and the gain of the Eternal City for the national cause. Prince Napoleon lent his support to this scheme, and from an article written by him we know that the two sovereigns discussed the matter almost entirely by means of confidential letters[13]. These discussions went on up to the month of June 1869. Francis Joseph, on hearing of them, urged the French Emperor to satisfy Italy, and thus pave the way for an alliance between the three Powers against Prussia. Nothing definite came of the affair, and chiefly, it would seem, owing to the influence of the Empress Eugenie and the French clerics. She is said to have remarked: “Better the Prussians in Paris than the Italian troops in Rome.” The diplomatic situation therefore remained vague, though in the second week of July 1870, the Emperor again took up the threads which, with greater firmness and foresight, he might have woven into a firm design.
