Moreover, 13 divisions, equipped with 6000 trucks, were organized in a central reserve, ready to be sent where it was needed.General Diaz learned the exact timing of the Austrian attack: 3:00 a.m. on 15 June, so at 2:30 a.m., the Italian artillery opened fire all along their front on the crowded enemy trenches, inflicting heavy casualties. In some sectors the artillery barrage had the effect of delaying or stopping the attack, as Austrian soldiers began to retreat to their defensive positions, believing they had to face an unexpected Italian attack, but on the greater part of the front the Austrians still attacked. Boroević launched the first assault, moving South along the Adriatic coast and in the middle course of the Piave River. The Austrians were able to cross the Piave and gained a bridgehead 15 miles (24 km) wide and 5 miles (8.0 km) deep in the face of Italian heavy resistance, before Boroević was finally stopped and forced to order a retreat. On the subsequent days Boroević renewed the assault, but the artillery barrage destroyed many of the river's bridges and the Austrian formations that crossed the river were unable to receive reinforcement and supplies. To make matters worse, the swollen Piave isolated a great number of units on the west bank of the river, which made them an easy target for the Italian fire. An estimated 20,000 Austro-Hungarian soldiers drowned while trying to reach the east bank. On 19 June, Diaz counterattacked and hit Boroević in the flank, inflicting heavy casualties.
In the meantime Conrad attacked along the Italian lines west of Boroević on the Asiago Plateau (on 15 June), with the objective of capturing Vicenza. His forces gained some ground, but came upon stiff resistance by Italian units; 40,000 casualties were added to the Austrian total. In the aftermath, Boroević was particularly critical about the behavior of Conrad who, after the complete failure of the first attack, preferred to continue the assaults in the subsequent days but with diminished strength, rather than send reinforcements to the Piave sector.
Lacking supplies and facing attacks by armored units, the Austro-Hungarians were ordered to retreat by Emperor Karl, who had taken personal command, on 20 June. By 23 June, the Italians recaptured all territory on the southern bank of the Piave and the battle was over.After the Austrian retreat Diaz was pressed by the allies, particularly by General Ferdinand Foch, to press on and try an assault to break the Austrian defences and gain a decisive victory over the Empire.
