WWI:
Prior to the outbreak of war in August 1914, Italy had tended to side with Germany and Austria-Hungary. To begin with, Italy kept out of the war. However, tempted by offers of more land once the war was won, Italy entered the war in April 1915 on the side of the allies. The Italian front is the name given to the fighting that took place along the border between Italy and Austria. The Italians only managed to advance a short way into Austria (shown by the red line on the map [Click to enlarge]). Between 1915 and 1917 there were twelve battles fought along the river Isonzo. just inside the Austrian border (shown in blue on the map). After being defeated at the battle of Caporetto the Italians were pushed back. The 1918 location of the Italian front is marked on the map in yellow
