Only in the event of the map of Europe being altered to the exclusive advantage of one great Power would France require an extension of frontier. Its interests
lay in the preservation of the equilibrium of Europe, and in the maintenance of the Italian Kingdom. These had already been secured by arrangements which would not require France to draw the sword; a watchful but unselfish neutrality was the policy which its Government had determined to pursue. Napoleon had in fact lost all control over events, and all chance of gaining the Rhenish Provinces, from the time when he permitted Italy to enter into the Prussian alliance without any stipulation that France should at its option be admitted as a third member of the coalition. He could not ally himself with Austria against his own creation, the Italian Kingdom; on the other hand, he had no means of extorting cessions from Prussia when once Prussia was sure of an ally who could bring two hundred thousand men into the field. His diplomacy had been successful in so far as it had assured Venetia to Italy whether Prussia should be victorious or overthrown, but as regarded France it had landed him in absolute powerlessness. He was unable to act on one side; he was not wanted on the other. Neutrality had become a matter, not of choice, but of necessity; and until the course of military events should have produced some new situation in Europe, France might well be watchful, but it could scarcely gain much credit for its disinterested part. [On May 11th Nigra, Italian ambassador at Paris, reported that Napoleon's ideas on the objects to be attained by a congress were as follows: Venetia to Italy; Silesia to Austria; the Danish duchies and other territory in North Germany to Prussia; the establishment of several small States on the Rhine under French protection; the dispossessed German princes to be compensated in Roumania. Napoleon III was pursuing in a somewhat altered form the old German policy of the republic and the empire - namely, the balancing of Austria and Prussia against each other, and the establishment of a French protectorate over the group of secondary States.]
Assured against an attack from the side of the Rhine, Bismarck was able to throw the mass of the Prussian forces southward against Austria, leaving in the north only the modest contingent that was necessary to overcome the resistance of Hanover and Hesse-Cassel. Through the precipitancy of a Prussian general, who struck without waiting for his colleagues, the Hanoverians gained a victory at Langensalza on June 27th; but other Prussian regiments arrived on the field a few hours later, and the Hanoverian army was forced to capitulate the next day. The King made his escape to Austria; the Elector of Hesse-Cassel, less fortunate, was made a prisoner of war. Northern Germany was thus speedily reduced to submission, and any danger of a diversion in favor of Austria in this quarter disappeared.
In Saxony no attempt was made to bar the way to the advancing Prussians. Dresden was occupied without resistance, but the Saxon army marched southward in good time, and joined the Austrians in Bohemia. The Prussian forces, about two hundred fifty thousand strong, now gathered on the Saxon and Silesian frontier, covering the line from Pirna to Landshut. They were composed of three armies: the first, or central, army under Prince Frederick Charles, a nephew of the King; the second, or Silesian, army under the Crown Prince; the westernmost, known as the Army of the Elbe, under General Herwarth von Bittenfeld. Against these were ranged about an equal number of Austrians, led by Benedek, a general who had gained great distinction in the Hungarian and Italian campaigns. It had at first been thought probable that Benedek, whose forces lay about Ohnuetz, would invade Southern Silesia, and the Prussian line had therefore been extended far to the east. Soon, however, it appeared that the Austrians were unable to take up the offensive, and Benedek moved westward into Bohemia. The Prussian line was now shortened, and orders were given to the three armies to cross the Bohemian frontier and converge in the direction of the town of Gitschin. General Moltke, chief of staff, directed their operations from Berlin by telegraph.
