easy to win him over to his views by explaining the temporary nature of the convention, and by dropping hints at the famous interview at Biarritz (September 30, 1865) of possible "compensations" to France in the event of a Prussian victory over Austria; the probability of a prolonged struggle in Germany between two powers apparently evenly matched, moreover, held out to the French emperor the prospect of his being able to intervene at the proper moment with overwhelming effect. End of the Austro-Prussian understanding. Napoleon having been successfully hoodwinked, Bismarck turned to Italy. His previous advances had been interrupted by the Gastein convention, which seemed to the Italian government a betrayal of the Italian cause. Italy attempted to negotiate with Austria for the purchase of Venetia; but the offer was curtly refused by the emperor Francis Joseph, and the counter-proposal of a commercial _rapprochement_ was forestalled by Prussia, which with the aid of most of the lesser states, angered by the betrayal of their interests by Austria at Gastein, arranged a commercial treaty between Italy and the Zollverein, an act which involved the recognition of the Italian kingdom. The counter-stroke of Austria was to embarrass Prussia by allowing full play in Holstein to the agitation in favour of the Augustenburg claimant. To the protests of Prussia, Austria replied that she had a full right to do what she liked in the duchy, and that she still adhered to the declaration of the princes, made on the 28th of May 1864, in favour of Duke Frederick. This "perfidy" removed the last scruples of King William; and the Austro-Prussian alliance came to an end with the declaration of Bismarck that Prussia "must win full freedom for her own entire policy" and his refusal to continue the correspondence.
