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. Various other successes of a similar nature were gained by the Italians during the next few days in this region, between the Avisio and the Vayol Cismon Valleys. In the meantime a heavy artillery bombardment had been started by the Italians on the Carso Plateau. From day to day the intensity of the artillery fire increased. At last on October 10, 1916, the Italians launched their attack against the Austrian lines south of Goritz and on the Carso. The battle lasted all day and night. After practically all the intricate Austrian defenses had been destroyed Italian infantry captured almost the whole of the line, composed of several successive intrenchments between the Vippacco (Wippach) River and Hill 208, and advanced beyond it. Novavilla and the adjoining strong position around the northern part of Hill 208 also fell into their hands after brisk fighting. Prisoners to the number of 5,034, including 164 officers, were taken and also a large quantity of arms and ammunition. These successes were considerably extended on the following day, October 11, 1916. Strong Austrian counterattacks availed nothing. The Italians maintained their new positions and continued to push their advance on the Carso Plateau and southeast of Goritz, even if slowly, throughout October 12 and 13, 1916. For the balance of the month there was little activity on the Isonzo front beyond extremely heavy artillery fire, most of which had its origin on the Italian side. Occasional attempts on the part of the Italians to push their lines still farther had little success. Equally unsuccessful were Austrian endeavors to regain some of the lost ground.
