The newly constituted 10th Army participated in the victory of the Battle of Vittorio Veneto (October–November 1918). The Army was inserted between the Italian 8th and 3rd Armies at the Piave River. The 8th Army was to cross the Piave River and advance to Vittorio in order to split the Austro-Hungarian Trentino Army from the ones defending Piave. The 10th Army was to protect their right flank. They were also expected to cross the Piave by breaking the Austro-Hungarian defenses at Grave di Papadopoli, a large island in the river.
