Since Pickett’s failed charge at Gettysburg, the frontal infantry assault had been known as obsolete. Nevertheless fifty years later, Allied military leaders in the Great War persisted in using it as a military tactic. Italian military leaders were no exception not even accepting the deadly effect of machine guns or quick-firing artillery. The Battles of the Isonzo on the Austro-Italian Front have now been classified with Verdun as to intensity and casualty lists. Mountain warfare on the Isonzo River Valley resulted in almost two million casualties from avalanches, frostbite, malaria, cholera, as well as prisoner-of-war starvation. Using the attacco frontale the blood of the illiterate fanti was used as coin to purchase terrain pushing the enemy back leading to Vienna's request to Berlin for help, leading to Caporetto.
