The Austrians tried to fall back on Vienna, but only three corps out of eight reached there, as the Prussian army by a rapid march had forced the others to seek refuge at Presburg. On July 18th the Prussian armies were concentrated on the Russbach. Archduke Albert, recalled from Italy, had taken command of the troops covering Vienna, but the internal condition of the empire, where Hungary was in agitation, was too disquieting for it to be possible, without aid, to continue the war. This aid Napoleon III could and should have furnished. The French army had suffered from the expedition to Mexico. Yet it would have been possible to put a hundred thousand men on foot immediately, and later on, Bismarck acknowledged that this would have sufficed to change the result. But Napoleon III was ill and swayed between opposing influences. Prince Napoleon, whom he heeded very much, was decidedly in favor of Prussia. Accordingly, no step was taken but an offer of mediation. Then he had the weakness, in spite of his minister, Drouyn de Lhuys, to consent to the annexations which Prussia wished to bring about in northern Germany. He asked, however, that Austria lose only Venetia, but it was precisely Bismarck’s will that had, and not without difficulty, persuaded King William that he must not, by territorial demands, compromise the alliance which he afterwards realized. On July 26th the peace preliminaries of Nikolsburg were signed. Austria paid a considerable indemnity, abandoned its former position in Germany, acknowledged the extension of Prussian authority to the line of the Main and the annexations which Prussia would deem it to its purpose to make. The three Danish duchies were likewise abandoned. It was stipulated only that the inhabitants of northern Schleswig should be consulted as to their wish to be restored or not to Denmark, which was never done. The definitive treaty was signed on August 25th at Prague. As for Italy, Francis Joseph had ceded Venetia to Napoleon III, who was to transmit it to Victor Emmanuel, but the Italians protested loudly against the idea of being satisfied with so little. They wanted in addition at least the Trent country. “Have you, then,” Bismarck said to them, “lost another battle to claim a province more?” On August 10th the preliminaries of peace were signed on that side. The final treaty, that of Vienna, was concluded on October 3, 1866. GERMANY AFTER 1866
