The Battles of Monte Grappa were a series of three battles which were fought during World War I between the armies of the Austro-Hungarian Empire and the Kingdom of Italy for control of the Monte Grappa massif, as it covered the left flank of the Italian Piave front.
The first of these battles became the most famous as it brought the Austrian advance to a halt following the Austro-Hungarian fall offensive of 1917. The Italian Chief of the general staff general Luigi Cadorna had ordered to construct fortified defenses on the Monte Grappa summit to make the mountain an impregnable fortress. When the Austro-Hungarian fall offensive of 1917 routed the Italians, the Austrians, with help from the German Army's Alpenkorps failed to take the mountain's summit during the first battle of Monte Grappa from November 11, 1917, to December 23, 1917. Thus, the Italian front along the Piave river was stabilized and, although the Austrians could see Venice from their positions, they would never reach it. Italian casualties totaled 12,000 and Austrian casualties 21,000.[1]
The second battle of Monte Grappa was complementary to the wider Austrian summer offensive of 1918, which was the last offensive operation of the Austro–Hungarian Army in World War I.
The third battle of Monte Grappa started on October 24, 1918, as part of the final Italian offensive of the war, when 9 Italian divisions attacked the Austrian positions on Monte Grappa. The Austrians answered by increasing their forces on the mountain from 9 to 15 divisions and thus committing all remaining reserves. But the worn down Austrian Army began a general retreat on October 28, when Czechoslovakia declared independence from Austria-Hungary.
