On May 23, 1915 Italy declared war on Austria-Hungary, however the Italian front quickly became a stalemate as the Battles of the Isonzo led to heavy casualties on both sides without any major territorial gains. In an attempt to break the stalemate, on May 15, 1916 "Army Group Archduke Eugen" under the command of the Archduke Eugen of Austria attacked into the Trentino area in Italy. Scheuchenstuel's VIII. Korps was included as part of the XI. Army which formed half of the Army Group. Initially the attacks, which became known as the Battle of Asiago, were successful. The Austrian army was able to open a 5 mile wide and 12 mile deep gap in the Italian lines. However, by June 10, 1916 the attack had stalled. Following the effective Russian Brusilov Offensive the Austrian attack stoped completely, and the VIII. Korps was transferred east.
