This indecisive three-year stretch of fighting in the Isonzo Valley came on the heels of Italy’s entry to World War I. Seeking to create a corridor to Vienna, Italian General Luigi Cadorna ordered a series of attacks on the region’s Austro-Hungarian fortifications beginning in June 1915. Cadorna finally had success on the sixth attempt, capturing Gorizia after its defenders were forced to shift resources to counter a Russian attack. When the eleventh attempt gave the Italians control of the strategic Bainsizza Plateau, the Austro-Hungarians sought help from Germany. The resulting Battle of Caporetto, also known as the Twelfth Battle of the Isonzo, was a decisive victory for the Central Powers.
