Armistice of Cormons

The Armistice of Cormòns was signed in Cormons on 12 August 1866, between the Kingdom of Italy (represented by General Count Agostino Petitti Bagliani di Roreto) and the Austrian Empire (represented by General Baron ) and was a prelude to the Treaty of Vienna, which ended the Third Italian War of Independence.

On 21 July 1866 the victorious Prussia, which had just inflicted a decisive defeat on Austrian army at the battle of Sadowa, signed the (without consulting the Italian allies). In the same days the Italian Navy was defeated in the Battle of Lissa. On the contrary the Army, after the defeat at Custoza, was taking advantage of the redeployment of many Austrian units to the Prussian front. Garibaldi's volunteers, reinforced by regular units, gained at great cost some terrain in Trentino and the main Italian army led by general Enrico Cialdini reached Udine, while a secondary army led by general Alfonso La Marmora was contemporary blocking some Austrian forces in the Quadrilatero fortresses.

After the armistice of Nikolsburg, Italian staff was afraid to face alone the entire Austrian Army, so they ordered to withdraw from Trentino (which was too tied to Habsburg Empire to be claimed). Garibaldi replied by telegraph with a sentence that became famous: Obbedisco ("I obey").

Soon after Prussia and Austria signed the Peace of Prague, while the definitive peace between Italy and Austria was ratified only on 3 October 1866 by the Treaty of Vienna, with the mediation of Napoleon III. The Austrian Empire recognized formally the Kingdom of Italy and ceded Venetia (that comprised Mantua, Veneto valley and western Friuli) to the French Empire, which in turn ceded it to Italy. This represented the final division of the Kingdom of Lombardy-Venetia, as Lombardy had been ceded to the Kingdom of Sardinia by the Treaty of Zurich in 1859.
