Marshal of Italy Luigi Cadorna, was an Italian general, Marshal of Italy and Count, most famous for being the Chief of Staff of the Italian Army from 1914 until 1917 during World War I. Commanding the Italian army on the Italian front, he acquired a reputation for rigid discipline and the harsh treatment of his troops. Cadorna launched multiple offensives across the Isonzo front during which the Italian army made gradual gains, notably capturing Gorizia after containing the Strafexpedition, but suffered heavy casualties. Following a major defeat at the Battle of Caporetto in late 1917, he was relieved as Chief of Staff.

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.

Although a member of the Triple Alliance, Italy did not join the Central Powers – Germany and Austria-Hungary – when the war started with Austria-Hungary's declaration of war on Serbia on 28 July 1914. In fact, the two Central Powers had taken the offensive while the Triple Alliance was supposed to be a defensive alliance. Moreover the Triple Alliance recognized that both Italy and Austria-Hungary were interested in the Balkans and required both to consult each other before changing the status quo and to provide compensation for whatever advantage in that area: Austria-Hungary did consult Germany but not Italy before issuing the ultimatum to Serbia, and refused any compensation before the end of the war.

The Battle of Hill 383 was a military engagement between the armies of Austria-Hungary and Italy on the Italian front of World War I, lasting from June 1915 to July 1917. The battle took place on a hill later called Mount Prižnica, located near the town of Plave in present Slovenia. The Italian and Austro-Hungarian armies clashed for two years in an attempt to occupy it; the bloodiest clash occurred on 17 June 1915 when General Luigi Cadorna wanted to offer king Victor Emmanuel III a conquest which he could witness in person. This "demonstration" caused the death of over 8,000 men who were massacred in a frontal attack against Austrian machine guns. The fighting was continuing for the next two years, until Mount Prižnica was took by Italians during the Tenth Battle of the Isonzo.
