After just over a month of fighting Prussia and Austria agreed to an armistice, on Prussian terms. Prussia's ally Italy continued its operations against Austria but without Prussian support was forced to accept a cease fire on August 12, 1866. The later Peace of Prague on August 23, 1866 confirmed the crushing Prussian victory and ended Austria's ambitions to become the leader of the German-speaking peoples while the Treaty of Vienna in October 1866 stripped the empire of several of its Italian-speaking provinces.
