The Battle of Caporetto, fought from October 24 to November 19, 1917, was a significant conflict during World War I. It involved the forces of the Austro-Hungarian Empire and Germany against the Italian Army. The battle marked a major defeat for Italy, leading to a retreat that caused a crisis in Italian morale and military strategy. The battle was characterized by the effective use of new tactics, including infiltration and surprise attacks, by the Central Powers. The aftermath saw the Italian front line collapse, prompting the Allies to reassess their strategies and support for Italy, which was crucial in the broader context of the war.
