In the reality, the Austrians had to retreat to Slovene territory, because they had less soldiers (they fought on two fronts). The Italians scarified many soldiers in order to advance toward Trieste and Ljubljana. Their generals used frontal assaults that were usually very deadly. On the other side, Austrians were better equipped and they tried to preserve as many soldiers as they could. They lost 41.835 soldiers.
