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 and the loss of significant territory. The battle is notable for the use of new tactics, including infiltration and surprise attacks, which contributed to the rapid success of the Central Powers. The aftermath of Caporetto prompted changes in Italian military strategy and led to increased support from the Allied Powers, particularly France and Britain.
