The front on the Austro-Hungarian border was long, stretching from the Stelvio Pass to the Adriatic Sea. Italian forces were numerically superior but this advantage was negated by the difficult terrain. Further, the Italians lacked strategic and tactical leadership. The Italian commander-in-chief was Luigi Cadorna, a staunch proponent of the frontal assault whose tactics cost the lives of hundreds of thousands of Italian soldiers. His plan was to attack on the Isonzo front, with the dream of breaking over the Karst Plateau into the Carniolan Basin, taking Ljubljana and threatening the Austro-Hungarian Empire's capital Vienna. It was a Napoleonic plan, which had no realistic chance of success in an age of barbed wire, machine guns, and indirect artillery fire, combined with hilly and mountainous terrain.
