Second Battle of the Piave River

The Second Battle of the Piave River (or Battle of the Solstice), fought between 15 and 23 June 1918, was a decisive victory for the Italian Army against the Austro-Hungarian Empire during World War I, as Italy was part of the Allied Forces, while Austria-Hungary was part of the Central Powers. Though the battle proved to be a decisive blow to the Austro-Hungarian Empire and by extension the Central Powers, its full significance was not initially appreciated in Italy.
