Book excerpt: Far removed from the bloody battles of attrition in the rain and mud of northern France, there raged another desperate struggle between two of Europeas strongest yet most underrated powers, the Kingdom of Italy and the Empire of Austria-Hungary. Here, along a twisting, curving 475-mile-long battle line, fierce fighting was conducted among the lofty peaks and rugged countryside of the continentas most notorious mountain range, replete with all the difficulties of weather and the awesome challenges of movement and supply. Contingents of troops from all of the major warring powers eventually became involved in this war of extremes. Before it was over, two and one-half million casualties had been suffered and the map of Europe had been changed forever. Battles in the Alps chronicles this important theatre of the Great War, and explains in text and in maps the consequences of Italyas entry into hostilities and the changes resultant from its aftermath. Related incidents in the skies over the Front and on the waves of the adjacent Adriatic Sea are also narrated.
