A general Italian advance took place on June 7 across the Isonzo River from Caporetto to the sea, a distance of about forty miles. On June 12 reports from the Trentino indicated an Italian advance on Rovereto in Tyrol, thirteen miles southwest of Trent, and upon Mori, near by. Monfalcone was taken by the Italians on June 10--the first serious blow against Trieste--as Monfalcone is a railway junction and its electrical works operate the light and power of Trieste. In the extreme north, on the threshold of the Carnic Alps, after three days' fighting it was reported on June 10 that the Italians had swept the Austrians from Monte Croce and possessed themselves of Freikofel. The Austrian city of Gradisca was reported taken on June 11, as indicated in an official statement signed by Lieut. Gen. Count Cadorna, Chief of Staff of the Italian Army. The defenses of Goritz were shelled by the Italian artillery on June 13, and on June 14 the Italian eastern army had pushed forward along the Gulf of Trieste toward the town of Nabresina, nine miles from Trieste.

On June 17 the Italians in the Trentino had arrived at the town of Mori, where their forces were blocked by the fortifications between that town and Rovereto. On June 18 a dispatch of The Associated Press from Rome reported that the Austrians had then so strengthened their forces that they were taking the offensive both from Mori and Rovereto against the Italians, who were encamped at Brentanico at the foot of Mount Altissimo, at Serravale, situated in the Lagardina Valley, and also in the Arsa Valley. Tolmino, on Austria's battlefront to the north of Goritz, was being heavily fortified by the Austrians with a garrison of some 30,000 men, this place being considered indispensable to their operations as the key to the Isonzo Valley. On June 20, the fourth week of the war, was reported by General Cadorna as marking a brilliant victory at Plava. But on the following day reports from Rome indicated that the Italians were encountering strong and better-organized resistance from the Austrians. On June 22 dispatches from the Italian front to Berlin declared that serious reverses had been experienced by the Italians in their attempts to storm the Austro-Hungarian line along the Isonzo River. Two things have puzzled the public: First, the status of Germany in regard to Italy declaring war against Austria-Hungary, arraying herself on the side of the Entente powers, and pledging herself, in turn, as each of them had done, not to make a separate peace with the enemy, and, second, the apparent weakness of the Austrian defensive in the Trentino and on the eastern frontier of Venetia.
