The Battle of Caporetto (also known as the Twelfth Battle of the Isonzo, the Battle of Kobarid or the Battle of Karfreit) took place on the Isonzo front of World War I.
The battle was fought between the Kingdom of Italy and the Central Powers and took place from 24 October to 19 November 1917, near the town of Kobarid (now in north-western Slovenia, then part of the Austrian Littoral), and near the river Isonzo. The battle was named after the Italian name of the town (also known as Karfreit in German).
Austro-Hungarian forces, reinforced by German units, were able to break into the Italian front line and rout the Italian forces opposing them. The battle was a demonstration of the effectiveness of the use of stormtroopers and the infiltration tactics developed in part by Oskar von Hutier.
