A few Garibaldian volunteers operating in the Trento area are the sole Italians to achieve some moderate success.

Garibaldi's "Hunters of the Alps" defeats the Austrians at the Battle of Bezzecca, on July 21, conquer the lower part of Trentino, and move towards Trento.

Prussian peace with Austria forces the Italian government to seek an armistice with Austria, on August 12.

Austria cedes Venetia to France according to the Treaty of Vienna, signed on October 12, which in turn cedes it to Italy.

Urbano Rattazzi had returned to power in the spring of 1867 and had given tacit consent to the stationing of Garibaldian volunteers along the papal border.

However, a renewed attempt to march on Rome in late October merely brings back French troops, who defeat Garibaldi at Mentana on November 3, aborting the second of his private expeditions to claim the Papal States for the Kingdom of Italy.

Giuseppe Garibaldi, arrested once again, is sentenced to house arrest on the remote island of Caprera, between Sardinia and Corsica, where he owns some property.

Italy suffers a marked loss of prestige politically and militarily, and the internal situation is far from favorable.
