In World War I, however, the Italian Front ran along Sella Nevea, while the bloody Battles of the Isonzo raged nearby. When in late 1917 Austro-Hungarian forces were able to break into the Italian front line during the Battle of Caporetto, they also rolled over the top of the pass, nevertheless, they again moved out of the area after the Austrian defeat at the Battle of Vittorio Veneto one year later. By the 1919 Treaty of Saint-Germain, the area of Cave del Predil (Raibl) and Tarvisio (Tarvis) north of the pass also fell to Italy.
