THE ITALIAN DRIVE AGAINST TRIESTE

It now became quite evident that the Italians once more were ready to attempt to reach their goal, Trieste. More and more violent became their bombardment of the Austrian lines on the Isonzo front. On May 14, 1917, on the Julian front from Tolmino to the sea the destructive fire of the Italian artillery, directed against strong Austrian positions, reached great intensity and was vigorously answered by numerous Austrian batteries of all calibers. Toward noon Italian infantry made several raids on various points along the front, which led to considerable progress in the Plava area, on the slopes of Monte Cucco, and on the hills east of Goritz and Vertoibizza. At the same time other Italian troops made a thrust in the northern sector of the Carso and reached the wrecked Austrian lines east of Dosso Faiti, capturing prisoners. The infantry actions continued during the entire day, supported by artillery and trench mortars, which were keeping the Austrian artillery in check.

On the remainder of the front the Austrians attempted various attacks in force on advanced positions northwest of Tolmino and on the Asiago Plateau. All were unsuccessful and resulted in severe casualties to the assailants.

This offensive action, it now appeared, had really begun on May 12, 1917, when, in the morning, fire was opened along the whole line from Tolmino to the sea. It was maintained with a regularly quickened rhythm until the morning of May 14, 1917, when it was intensified to a powerful drum fire. During the first part of the bombardment the Austrians reacted but feebly. It seemed as though the Austrians had been taken by surprise, but their reply was more vigorous on May 13, 1917, and extremely violent on the morning of the 14th. Austrian batteries then opened a heavy curtain of fire, pouring thousands of projectiles on the trenches in the Italian line. Undeterred by this tempest of fire, the Italian infantry, toward noon, leaped over the parapets and dashed forward toward the objectives previously assigned. These positions were almost all difficult ones, and some of them hitherto had been regarded as impregnable; such, for instance, as the heights on the left bank of the Isonzo, from Plava to Salcano Pass. The steep slopes, covered with rocks and dotted here and there with thick clumps of brush, constituted a formidable obstacle to an infantry advance. Successive lines of trenches, prepared months before above deep caverns, well supplied with defensive and offensive material, were defended by seasoned troops and protected by batteries placed so as to flank attacks with their fire. Notwithstanding these conditions, the Italian infantry advanced.

This vigorous offensive movement was continued by the Italian troops on May 15, 1917. Ably supported by artillery, they succeeded in establishing themselves on the steep and wooded heights along the eastern bank of the Isonzo, north of Goritz, which had been transformed by the Austrians into a formidably fortified defensive position. On the left wing one of the Italian columns, after forcing a passage across the river between Loga and Bombrez, captured the last-named village and fortified itself there.

In the center the heights of Hill 383, northeast of Plava, were captured, while the Florence infantry brigade and the Vaellino brigade, after taking by assault the villages of Zagora and Zagomila, which were infested by machine guns, carried the crests of Monte Cucco and Monte Vodice with great dash.

On the right wing the other Italian columns made considerable progress on the steep slopes of Monte Santo. Fierce Austrian counterattacks, prepared and supported by a bombardment of exceptional violence, were all repulsed.

In the area east of Goritz the Messina brigade conquered Hill 174 north of Tivoli, which was strongly fortified and stubbornly held by the Austrians, whose insistent counterattacks were beaten back.

The city of Goritz suffered a heavy bombardment from Austrian batteries, and some buildings were seriously damaged. On the remainder of the front down to the sea there were lively artillery actions. The Austrian rear lines were again effectively bombed by air squadrons and during the night by airships.

In the first two days of their advance the Italians made 3,375 prisoners, among them ninety-eight officers. They also captured a mountain battery, about thirty machine guns, and much war material, including arms and ammunition.

On the following day, May 16, 1917, the Austrian resistance stiffened somewhat. In spite of this the Italian advance continued. Fighting in the zone between Monte Cucco and Vodice was bitter and lengthy. Considerable Austrian masses, supported by the fire of numerous batteries, were repeatedly launched against Italy's new positions. Each time they were repulsed, and the Fochux bastion of Monte Cucco from Height 611 to Height 525 remained firmly in Italian hands. Moreover, the Italians made appreciable progress toward the important summit of Height 652, on the Vodice.

In the zone east of Goritz Austrian counterattacks, directed particularly against the summit of Height 174 and to the east of the Vertoibizza Torrent, broke down under Italian fire. Afterward Italian infantry, assuming a counteroffensive, occupied the important height to the south of Grazigna after a desperate conflict.

On the Carso Plateau the Austrians, with the evident object of lessening the Italian pressure in the region of Goritz, attempted a powerful effort against positions at Monte Vuocgnacco and Monte Faiti, on the northern sector of the plateau. Successive waves of Austrian infantry were broken down by well-directed fire, or rolled back in disorder after having suffered serious losses.

On the whole front from Tolmino to the sea there were continuous actions by artillery of all calibers. The Austrian artillery continued its work of devastation on the city of Goritz.

On May 17, 1917, the Italian troops were engaged in fortifying the important position captured east of Goritz and organizing communication with the rear. The Austrians attempted but failed to hinder the work of the Italian forces.

During the night the Austrians under cover of darkness attempted surprise attacks upon positions on the bridgehead of Bodrez (on the Isonzo seven miles southwest of Tolmino), on the Vodice, Hill 592, and at Grazigna. In the morning the Austrians brought up strong reenforcements and renewed their attack, which was particularly violent in the Vodice region and south of Grazigna. Shattered by Italian battery fire the Austrian masses were counterattacked and repulsed by infantry, who at several points surrounded their assailants and forced them to surrender.

The number of prisoners by now had increased to 6,432, including 143 officers.

All along the front from Tolmino to the sea the artillery continued very active. Goritz again suffered very heavy damage.

Surprise attacks during the night of May 17, 1917, on Italian positions on the heights of Hill 592 on Monte Vodice were repulsed. In the morning of May 18, 1917, Italian troops opened a vigorous attack, with the object of capturing the heights of Hill 652 on Monte Vodice, the key to the Austrian defenses north of Monte Santo. The stubborn resistance of the Austrians, supported by numerous batteries of all calibers, which kept up a continuous fire from the rear, rendered the action long and severe. Advancing from rock to rock, expelling the Austrians from trench and cavern, destroying their machine guns, Italian infantry by evening succeeded in reaching the crest of the long-contested heights and maintaining the position against the concentrated fire of Austrian batteries.

With the capture of the ridge between Monte Cucco and Monte Vodice, the task of diverting the Austrian attention, which was assigned to the troops in the sector between Bodrez and Loga, was completed, and they withdrew to the right bank of the Isonzo without molestation from the Austrians.

In the region east of Goritz the Italians maintained all their positions against persistent attacks, which were particularly violent south of Grazigna and on the heights of Hill 174 south of Tivoli. On the remainder of the front incessant artillery duels occurred. The Austrian fire was especially violent against Goritz and the surrounding villages.

In the area north of Goritz the Italian troops on May 19, 1917, extended their positions on Hill 652, on the Vodice (a ridge which links captured Monte Cucco with Monte Santo, the immediate Italian objective in this region). Dense masses of Austrians preceded by a heavy barrage fire counterattacked in an attempt to stop the Italian progress, but each time were driven back with heavy loss. In the evening the Austrians withdrew their infantry, and concentrated a strong artillery fire on the lost positions. These the Italians firmly maintained. They captured two 4-inch guns, two 6-inch mortars, trench mortars and machine guns, and a large quantity of arms and ammunition. In the area east of Goritz Italian troops broke into the Austrian line and took some prisoners. On the Trentino front the Austrians attempted a diversion by a heavy bombardment and by local infantry attacks without success.

These attempts were resumed on May 20, 1917, in the Trentino, in the Campo area, in the Daone Valley, southeast of Lake Loppio, at Rio Cameras, in the Adige Valley, and on the Maso Torrent line in the Sugana Valley. Late in the evening masses of Austrian troops vigorously assaulted Italian positions on the Pasubio, west of Monte Dente. After heavy hand-to-hand fighting, the Austrians, suffering severe loss, were completely driven back all along the line of attack. On the Julian front, Austrian attacks on the northern slopes of San Marco, east of Goritz, between Monte Vuocgnacco and Monte Faiti, and in the neighborhood of Hill 268 were repulsed. The Italians took Hill 363, between Palieva and Britof, east of Plava, and extended their positions still more on the Vodice.

On May 21, 1917, the Austrians on the Trentino front, notwithstanding the repulse so far suffered, persisted in making desultory and fruitless attempts to divert the Italians from their main objectives. Raids were made in force against the advanced Italian line at Caventro Pass, Adamello, Pluberga Bridge, in the Chiesa, and in the Giumella Valley, at Rio Pionale. All were repulsed. Between Lake Garda and the Adige the Austrians, after an intense and prolonged bombardment with artillery of all calibers, attacked positions on Monte Dosso Alto, southwest of Loppio Lake, and on Monte Zugna. They were driven back with heavy loss. Other local attacks which were attempted in the Posina Valley, on the Asiago Plateau, and in Carnia failed. On the Julian front, in the sector north of Goritz, the artillery duel, already spirited, became more intense, but was not followed by infantry action. The position which the Italians captured on Hill 363, east of Plava, was consolidated.

East of Goritz the Austrians attempted repeatedly to recapture Hill 126, south of Grazigna, but failed on account of the effective action of Italian artillery reserves.

A slight lull set in on May 22, 1917, except that the Italians opened a very heavy fire against the Austrian positions on the Carso Plateau.

This bombardment continued on May 23, 1917, and after ten hours of violent bombardment, the troops of the Third Italian Army assaulted and broke through the well-organized Austrian lines from Castagnievizza to the sea. While they were heavily engaging the Austrians on the left, other troops, after carrying trenches in the center and on the right, occupied part of the area south of the Castagnievizza-Boscomalo road, passed Boscomalo and captured Jamiano, the important and strongly fortified heights of Hill 92 east of Pietrarossa, Hill 77, Hill 58, Bagni, and Hill 21. The Austrians, at first surprised by the sudden onslaught, toward evening counterattacked in force, supported by an exceptionally heavy bombardment. They were repulsed with severe loss.

During the day the Italians captured more than 9,000 prisoners, including more than 300 officers. In the Goritz area Italian troops repulsed heavy attacks, captured a strong point on the northwest slopes of San Marco, and after severe fighting made considerable gains in the Monte Santo and Vodice areas.

It was also announced officially that ten British batteries assisted in the fighting of these days. On May 24, 1917, the battle continued to rage along the Julian front from the sea to Plava. Italian troops, advancing over very difficult and intricate ground, fought their way, yard by yard, through a deep labyrinth of fortifications stubbornly defended by strong, well-trained forces.

In the sector between the sea and the Jamiano-Brestovizza road large Italian forces, supported by some field batteries which advanced with the infantry, drove the Austrians back as far as Foce Timavo, Flondar, and Hill 31, a line south of Jamiano.

North of Jamiano, after heavy fighting, the strongly fortified heights Hills 235 and 247 were carried and the Italian positions extended as far as the outlying houses of Versic.

The Austrians attempted to lighten the Italian pressure on the southern Carso by violent counterattacks from Castagnievizza to Frigido. All these efforts failed. East of Goritz persistent Austrian raids were repulsed during the night on Hill 174, north of Tivoli, and at Grazigna. In the region of Monte Cucco and Monte Vodice the Austrians vainly made every effort to retake captured positions. An Austrian column attempted a surprise attack against Italian lines east of Hill 652 on the Vodice. It was counterattacked and driven back to its point of departure, which was then carried and held by Italian troops. East of Plava the Italians extended their occupation on Hill 363.[Back to Contents]
