Italy in World War One

In May 1915, Italy entered WW1 on the side of the Allies, fighting against the Austro-Hungarian Empire and Germany. Their war was not fought on the Western front, but in the mountains of the Alps. Using the diary of an Italian soldier, Alan Johnston tells the story of one man's war.
