Garibaldi took up arms again in 1866, this time with the full support of the Italian government. The Austro-Prussian War had broken out, and Italy had allied with Prussia against the Austrian Empire in the hope of taking Venetia from Austrian rule (Third Italian War of Independence). Garibaldi gathered again his Hunters of the Alps, now some 40,000 strong, and led them into the Trentino. He defeated the Austrians at Bezzecca, and made for Trento.
