I. - IV. Isonzo battle

3. III. Isonzo battle

18 October 1915 - 4 November 1915

After three days of artillery shelling, the Italian 3rd Army attacked Monte San Michele on 13 and 14 October. For both days the peak was under the gunfire of the Italian artillery, and the day after, the infantry attacked. On October 18th, they were already fighting across the Salt Queens Zone, from Krun to the Gulf of Panzan. Initially, the Italian divisions repeatedly attacked Krn, Tolmin and Plavy, the Mrzlim litter, Kanal, the Goric bridgehead, Gorice and Montfalcone. Still, the Italians managed to achieve only small territorial gains.
The four Italian brigades attacked the Plateau of the Krass in 2 km between Monte San Michele and San Martin del Carso, where the fighting lasted until November 3. Breaking the Austro-Hungarian defense with the Italian striker failed even though he managed to penetrate it in several places. For the first time, the Italian Air Force invaded the Austro-Hungarian ground defense.
