On the 15th of June the Italians carried an important position on Monte Nero, climbing the rocks by night and attacking by dawn. But this conquest did not help much. No guns of great caliber could be carried on the mountain, and Tolmino, which had been heavily fortified, and contained a garrison of some thirty thousand men, was entirely safe. The following week there were repeated counter-attacks at Plava and on Monte Nero, but the Italians held what they had won. The position was now that Cadorna’s left wing was in a strong position, but could not do much against Tolmino. His center was facing the great camp of Gorizia, while his right was on the edge of the Carso, and had advanced as far as Dueno, on the Monfalcone-Trieste Railroad. The army was in position to make an attack upon Gorizia. On the 2d of July an attack on a broad front was aimed directly at Gorizia. The left was to swing around against the defenses of Gorizia to the north; the center was directed against the Gorizia bridge head, and the right was to swing around to the northeast through the Doberdo plateau. If it succeeded the Trieste railway would be cut and Gorizia must fall.

The center and the right of the Italian army slowly advanced their line, taking over one thousand prisoners. For days there was continuous bombardment and counter-bombardment. The fighting on the left was terrific. In the neighborhood of Plava the Italian forces found themselves opposed by Hungarian troops, unaccustomed to mountain warfare, who at first fell back. Austrian reserves came to their aid, and flung back three times the Italian charge. Three new Italian brigades were brought up, and King Victor Emanuel himself came to encourage his troops. The final assault carried the heights. On the 22d of July the Italian right captured the crest of San Michele, which dominates the Doberdo plateau. Meanwhile the Austrian armies were being heavily reinforced, and General Cadorna found himself unable to make progress. Much ground had been won but Gorizia was still unredeemed. Many important vantage points were in Italian hands, but it was difficult to advance. The result of the three months’ campaign was a stalemate. In the high mountains to the north Italy’s campaign was a war of defense. To undertake her offensive on the Isonzo it was necessary that she guard her flanks and rear. The Tyrolese battle-ground contained three distinct points where it was necessary to operate; the Trentino Salient, the passes of the Dolomites, and the passes of the Carnic Alps.
