Who? What? Where? When?
Italy had sided up with Germany and Austria-Hungary in the Triple Alliance in the years leading up to World War One because of rivalries with France and North Africa. But as the war progressed, Italy switched sides and joined the Triple Entente with Britain, France and Russia. Italy seen Germany and Austria-Hungary’s actions as aggressive rather than a defensive reason and that they were not obligated to contribute their war effort. Britain supplied Italy with 90% of its annual imports on coal which positively affected them. So then Italy and Britain were already on good terms. Britain and France convinced Italy to join the war effort and said they’ll gain territories as that was a problem between Austria-Hungary and Italy in the first place. This promise of territorial distribution is known as the London Pact. Their enemies were obviously the Triple Alliance now that they joined the Triple Entente. Italy officially declared war on Austria-Hungary May 23rd, 1915, a year after joining the Triple Entente. Italy was numerically superior to Austria-Hungary but lacked strategic leadership. The leader costed hundreds of thousands of lives of Italian soldiers. A “Napoleonic plan” that was thought of with no realistic outcome of winning with the era’s new weapons was an example of a terrible leaded battle. The Battle of Isonzo in 1915 resulted in Italy outnumbering Austria-Hungary but their poor military tactics led by a disliked leader caused them to be terrible on offense. The Sixth Battle is when Italy finally gained Gorizia which boosted their confidence a bit. Overall, they were only superior in numbers. (http://www.history.com/topics/world-war-ii/italian-campaign)
