The Italian Army was in all-out retreat after the Austrian autumn offensive of 1917. The Italian Chief of the general staff general, Luigi Cadorna, had ordered the construction of fortified defenses around the Monte Grappa summit in order to make the mountain range an impregnable fortress. When the Austrian offensive routed the Italians, the new Italian chief of staff, Armando Diaz, ordered the Fourth Army to stop their retreat and defend these positions between the Roncone and the Tomatico mountains, with the support of the Second Army.
