In spite of the fact that on May 30, 1916, the Austrians had forced their way across the Posina torrent between Posina and Arsiero and succeeded in partly enveloping the latter, a force which attempted to take Sant' Ubaldo, immediately southeast of Arsiero, on May 31, 1916, was driven back by the Italians beyond the Posina, thus relieving the strongest pressure on the town. A little further west another Austrian force attacked the Italian positions on Monte Spin, southeast of Posina. The Italian lines held on the mountain slopes and the Austrian advance here was checked. West of Posina an Austrian assault on Monte Forni Alti was repulsed. On the Sette Comuni Plateau, where the Austrians were advancing against Asiago, they began operations against the Italian positions on Monte Cengio and Campo Niulo. On June 1, 1916, however, the Austro-Hungarians in the Arsiero region captured Monte Barro and gained a firm footing on the south bank of the Posina torrent. Repeated night attacks along the Posina front against the northern slopes of Monte Forni Alti and in the direction of Quaro, southwest of Arsiero, were repulsed. All day long an intense uninterrupted bombardment by Austrian batteries of all calibers was maintained against the Italian lines in the Col di Xomo-Rochette sector (southwest of Posina). On the left wing the Austrians, leaving massed heavy forces between Posina and Fusine (in the Posina Valley, east of Posina), made numerous efforts to advance toward Monte Spin. On the right wing strong Austro-Hungarian columns in the afternoon launched a violent attack against Segheschiri. These were completely repulsed after a fierce engagement. In the uplands of the Sette Comuni there was an intense and obstinate struggle along the positions south of the Assa Valley as far as Asiago. Italian troops holding the Monte Cengio Plateau determinedly withstood powerful infantry attacks supported by a most violent bombardment. On the front parallel with the Asiago-Guglio-Valle road near Campo Mullo the Italians gained ground by a violent counteroffensive in spite of the strong Austrian resistance. Intense artillery and infantry fighting along the Trentino front continued unabated on June 2, 1916, and according to the official Italian statement the Austrian offensive in some places was checked. The Austrian infantry on Zugna Torta was scattered by the fierce Italian infantry fire. Around Asiero and on the Asiago Plateau in Italy, the Italians repulsed Austrian infantry. The Belmonte position northeast of Monte Cengio, where the struggle was fiercest and which was repeatedly taken and lost, was finally definitely occupied by the Italians. Several Italian towns, including Vicenza and Verona, were attacked by Austrian aeroplanes, while Italian air squadrons in a raid on objects of military importance in the lower Astico Valley, dropped 100 bombs on various enemy camps and munition depots.
