In 1865, the Prussian chancellor Bismarck submitted to Austria a proposal that Austria cede the provinces of Schleswig and Holstein to Prussia for a certain monetary compensation. At the same time, Italy offered Austria a thousand million lire for Venice. Austria flatly rejected both offers, and then Prussia and Italy concluded a pact on a joint attack on Austria. If Prussia attacks Austria, Italy will also attack it. The peace would be concluded so that Italy would get Venice, and Prussia some parts of Austria. On June 23, the Italian army crossed the Minzio, which opened up the southern Italian battlefield, and Austria was drawn into the war on two fronts.
