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.
