"Throughout July the Austro-Hungarians were aware that the Italians were preparing for another offensive. Towards the end of July and into August increasing numbers of Italian deserters, desperate to escape the coming carnage, brought detailed intelligence of the Italian dispositions. During the same period the bomber squadrons of the Italian air force became much more active and aggressive in attacking rear areas, particularly on the Bainsizza Front. One spectacular raid on 11 August destroyed the main ammunition dump for the plateau front at Grapa. This would weaken the Austrian artillery support to their embattled army in the coming weeks."
Italian commander in chief Luigi Cadorna launched four offensives on the Isonzo River along Italy's northeastern border in 1915 and five in 1916. His Tenth Battle of the Isonzo raged from May 12 through June 8, 1917. At the beginning of August he prepared for the next Battle of the Isonzo, the Eleventh.
