On September 8, 1916, in the Tofana zone Italian troops repulsed an attack against the position in the Travenanzes Valley which their troops had taken on September 7, 1916.
On the Trentino front the activity of the artillery was more pronounced on September 9, 1916. Unimportant attacks on Italian positions on Malga Sugna, in the Vallarsa, on the Asiago Plateau, and on Monte Cauriol and Avisio, were repulsed. At Dolje, in the Tolmino sector, after preparation with hand grenades, the Austrians attempted to break through the Italian line, but were driven back immediately.
On the next day, September 10, 1916, between the Adige and Astico Valleys the Italians developed increased activity. Austrian hill positions in this sector were subjected to strong artillery and mine fire. On the Monte Spil-Monte Testo sector the advance of several Italian battalions was repulsed.
On the same day the coast front, the Carso Plateau, and the Tolmino bridgehead were shelled strongly by Italian artillery. On some sectors of the Tyrol front there was continued activity on the part of patrols and the artillery. In the zone between Vallarsa and the head of the Posina Valley Italian infantry captured a strong intrenchment at the bottom of the Leno Valley. Between Monte Spil and Monte Corno they completed capture of the trenches still left in Austrian hands after the fighting of September 7, 1916. Progress was made by the Italians on the ground north of Monte Pasubio and on the northern slopes of Corno del Coston, in the upper Posina Valley. Italian batteries destroyed military depots near St. Ilanio north of Rovereto. The Austrians shelled Caprile, in Cordevole Valley, and Cortina d'Ampezzo.
On September 12, 1916, Italian Alpine troops, north of Falzarego gained possession of a position which not only commanded Travenanzes Pass, but also interrupted communications between the Travenanzes Valley and the Lagazuoi district.
This success was extended on the next day, September 13, 1916, when Italian detachments by a daring climb succeeded in taking some positions in the Zara Valley in the Posina sector and on Monte Lagazuoi in the Travenanzes-Boite Valley.
Once more, on September 14, 1916, the Italians opened a new offensive in the region of the Carso Plateau. Artillery and mine fire increased there with the greatest violence. In the afternoon strong infantry forces in dense formation advanced to the attack. Along the whole front between the Wippach River and the sea fierce fighting developed, and the Italians in some places succeeded in penetrating the Austrian first-line trenches and in maintaining themselves there. North of the Wippach, as far as the region of Plava, artillery fire was very lively, but no infantry engagements worth mentioning developed. In the Fiemme Valley artillery duels continued. Several attacks delivered by Italian detachments about a battalion strong against the Bassano ridge were repulsed.
A second attack on the Carso Plateau in the evening of September 14, 1916, carried the Italian lines forward a few more miles and enabled them to surround the height and village of San Grado. After bombarding the Austrian positions for eight hours, this height and the village were stormed on the following day, September 15, 1916.
During the balance of the month of September, 1916, only minor engagements and artillery duels occurred in the various parts of the Austro-Italian front. The only exception was a successful Austrian attack against the summit of Monte Cimone on the Trentino front southeast of Rovereto. Early in the morning of September 23, 1916, the entire summit was blown up by an Austrian mine and the entire Italian force of about 500 men was either killed or captured. Later that day the Italians captured the summit of the Cardinal (8,000 feet) at the northeast of Monte Cauriol south of the Avisio after overcoming the most stubborn Austrian resistance.
During the first half of October, 1916, activities on the Austro-Italian front presented much the same picture as during the preceding month. Outside of artillery duels and local engagements there happened little of interest or importance to the general positions. However, there were of course a few exceptions. Thus on October 2, 1916, Italian troops captured two high mountains, the Col Bricon (7,800 feet), at the head of the Cismon-Brenta Valley, and an unnamed peak more than 8,000 feet high, in Carnia between Monte Cogliano and Pizzocollima.
