deployed to Mount Sabotino), that counter failed. With the conquest of Monte Sabotino and Monte San Michele, the previously strong Austro-Hungarian defensive line around Gorizia rapidly disintegrated. Then Monte Calvario fell during that night. On the right bank of the Isonzo there was only one regiment who then withdrew to the east on 8 August. The first platoons of the Pavia Brigade began to enter the city. Gorizia fell to Cadorna and a bridgehead was finally established across the Soča (Isonzo) River. The Austro-Hungarians shifted troops to the Gorizia sector to prevent a breakthrough. Borojevic, had already ordered his men to retreat further to the east, into a valley called The Vallone. Thus strategic positions on the western Carso such as Monte Sei Busi, the zone around Doberdò del Lago and Monte Cosich to the north of Monfalcone (which the Vallone separated from the eastern Carso) were thus abandoned. However, the Austro-Hungarian defenses in the north and east of Gorizia still included an uninterrupted series of heights – including ridges from Monte Santo, Monte San Gabriele, Monte San Daniele. These heights and Quota 383 lent themselves to place the Austro - Hungarian artillery and provide excellent observatories after the fall of Gorizia. These heights had been prepared for defense purposes and made it possible to block any passage towards by the Italian troops to Vienna and Trieste. The new Austro-Hungarian front line now passed to Nad Logem (Quota 212), Quota 187 (near Devetachi), Opacchiasella, Nova Vas and Quota 208 north and south, Quota 144 and Quota 77 and the Austro-Hungarian troops engaged the Italians in a series of heavy, defensive firefights. Content with having established the bridgehead, capturing Gorizia and the western Karst, and having suffered heavy losses, Cadorna ended the offensive on 17 August. The attack on Gorizia was the most successful Italian offensive along the Isonzo lines and greatly boosted Italian morale - especially since Gorizia had been promoted as a desirable objective, unattainable in earlier battles. In the wake of the battle Italy finally declared war against Germany, on 28 August. .
