Another brilliant feat of arms, the transference of the Prussian troops across the sea to the island of Alsen, completed the war. Denmark had to capitulate, and the terms of peace, which were ultimately decided at Vienna, were that Schleswig, Holstein, and also Lauenburg should be given up. Christian transferred to the Emperor of Austria and the King of Prussia all the rights which he possessed. As to Lauenburg the matter was simple--the authority of the King of Denmark over this Duchy was undisputed; as to Schleswig-Holstein all the old questions still continued; the King had transferred his rights, but what were his rights? He could only grant that which belonged to him; if the Prince of Augustenburg was Duke, then the King of Denmark could not confer another man's throne. There was, however, this difference: hitherto the question had been a European one, but since the London Congress no other State had any claim to interfere. The disputed succession of the Duchies must be settled between Austria and Prussia. It was a special clause in the terms of peace that it should be decided by agreement between them and not referred to the Diet. CHAPTER IX. THE TREATY OF GASTEIN. 1864-1865. Bismarck always looked back with peculiar pleasure on the negotiations which were concluded by the Peace of Vienna. His conduct of the affair had in fact been masterly; he had succeeded in permanently severing the Duchies from Denmark; he had done this without allowing foreign nations the opportunity for interfering; he had maintained a close alliance with Austria; he had pleased and flattered the Emperors of Russia and France. What perhaps gave him most satisfaction was that, though the result had been what the whole of the German nation desired, he had brought it about by means which were universally condemned, and the rescue of the Duchies had been a severe defeat to the Democratic and National party. With the Peace a new stage begins; the Duchies had been transferred to the Allied Powers; how were they now to be disposed of? We have seen that Bismarck desired to acquire them for Prussia; if it were absolutely necessary, he would accept an arrangement which would leave them to be ruled by another Prince, provided very extensive rights were given to Prussia. He would acquiesce in this arrangement if annexation would involve a war with one of the European Powers. If, however, a Duke of Schleswig-Holstein was to be created he was determined that it should not be the Prince of Augustenburg, whom he distrusted and disliked. The real object of his diplomacy must be to get the Duchies offered to Prussia; it was, however, very improbable, as the Czar once said to him, that this would happen.
