The Battle of Doberdò took place near Doberdò del Lago in August 1916 between armies of Kingdom of Italy and Austria-Hungary. The Austro-Hungarian army was primarily made up of regiments filled with Hungarians and Slovenians. The battle was a part of the sixth battle of the Isonzo, and occurred in a strategic area of westernmost edge of the Karst Plateau. Italians had already conquered the lowland area surrounding Monfalcone and Ronchi, and attempted to push over the Karst Plateau to seize control of the major road that linked the city of Trieste and its port with Gorizia. After fierce combat, and sustained heavy casualties, Italian forces forced Austro-Hungarian forces to retreat and captured Gorizia.
