The Italian campaign refers to a series of battles fought between the armies of Austria-Hungary and Italy, along with their allies, in northern Italy between 1915 and 1918. Italy hoped that by joining the countries of the Triple Entente against the Central Powers she would gain the province of Trento (Trentino) and the port of Trieste, as well as the province of Bolzano-Bozen (Alto Adige/Südtirol), Istria and Dalmatia. Although Italy had hoped to begin the war with a surprise offensive intended to move quickly and capture several Austrian held cities, the war soon bogged down into trench warfare similar to the Western Front.

Causes for the campaign

Although a member of the Triple Alliance with Austria-Hungary and Germany, Italy did not declare war in August 1914, arguing that the Alliance was defensive in nature and Austria-Hungary's aggression did not obligate Italy to take part. Italy had a long standing rivalry with Austria-Hungary, dating back to the Congress of Vienna in 1815 after the Napoleonic Wars, which ceded several important Italian regions to Austria. In the early stages of the war, Allied diplomats courted Italy, attempting to secure Italian participation on the Allied side, culminating in the Treaty of London of April 26, 1915 in which Italy renounced her obligations to the Triple Alliance. On May 23, Italy declared war on Austria-Hungary.

Campaigns of 1915-1916

First battles of Isonzo

Italy opened the war with an offensive aimed at capturing the town of Gorizia on the Isonzo river. However, the Italian Army was poorly equipped in artillery, vehicles, and ammunition. At the beginning of the war, Italy had just 600 vehicles to move troops. As with most contemporary militaries, the Italian army primarily used horses for transport, and these failed to move supplies fast enough in the tough terrain of the Alps. Also, the newly appointed Italian commander, Luigi Cadorna, had no combat experience and was highly unpopular amongst his men.

At the beginning of the offensive, Italian forces outnumbered the Austrians 2 to 1, but failed to penetrate their strong defensive lines along the Alps. This was mostly due to the Austrian forces being based on higher ground, and so Italian offensives had to be conducted climbing. Two weeks later, the Italians attempted another frontal assault with more artillery but were beaten back again. Another attack was mounted from October 18 to November 4 with 1,200 heavy guns, which again resulted in no gain.

The Asiago offensive

Following Italy's disastrous offensives, the Austrians began planning a counteroffensive (Strafexpedition) based in Trentino and directed towards the plain across the Altopiano di Asiago. The offensive began on March 11, 1916 with 15 divisions breaking the Italian lines. Though warned of an impending offensive, the local Italian commander had chosen to conduct local offensives instead of preparing a defense. The unprepared Italian positions collapsed and Italy only staved off defeat by quickly transferring reinforcements from other fronts.

Later battles for the Isonzo

Later in 1916, four more battles along the Isonzo river erupted. The Sixth Battle of the Isonzo, launched by the Italians in August, resulted in a success greater than the previous attacks largely because the Austrians had depleted their lines for the Brusilov Offensive. The offensive gained nothing of strategic value but did take Gorizia, which boosted Italian spirits. The Seventh, Eighth, and Ninth battles of the Isonzo (September 14-November 4) managed to accomplish little except to wear down the already exhausted armies of both nations.

1917: Germany arrives

Following the minuscule gains of the Tenth Battle of the Isonzo, the Italians directed a two-pronged attack against the Austrian lines north and east of Gorizia. The Austrians easily checked the advance east, but Italian forces under Luigi Capello managed to break the Austrian lines and capture the Bainsizza Plateau. Characteristic of nearly every other theater of the war, the Italians found themselves on the verge of victory but could not secure it because their supply lines could not keep up with the front-line troops and they were forced to withdraw.

The Austrians received desperately needed reinforcements after the Eleventh Battle of the Isonzo from German Army soldiers rushed in after the Russian offensive ordered by Kerensky (Kerensky Offensive) of July 1917 failed. The Germans introduced infiltration tactics (Hutier tactics) to the Austrian front and helped work on a new offensive. Meanwhile, mutinies and plummeting morale crippled the Italian Army from within. The soldiers lived in poor conditions and engaged in attack after attack that often yielded minimal or no military gain. On October 24, 1917 the Austrians and Germans launched the Battle of Caporetto (Italian name for Kobarid) with a huge artillery barrage followed by infantry using Hutier tactics, bypassing enemy strong points and attacking on the Italian rear. At the end of the first day, the Italians had retreat 12 miles to the Tagliamento River.

1918: The war ends

Battle of the Piave

Advancing deep and fast, the Austrians overran their supply lines, which forced them to stop and regroup. The Italians, pushed back to defensive lines near Venice on the Piave River, had suffered 600,000 casualties to this point in the war. In November 1917, British, French and US forces started to bolster the front line, though not in decisive numbers; the Italians were able to contain the Austrian offensive largely by themeselves. Far more decisive than Allied help in troops, indeed, was Franco-British (and US) help provided in those strategic materials (coal, steel, etc.) Italy always lacked sorely. In the spring of 1918, Germany pulled out its troops for use in its upcoming Spring Offensive. The Austrians now began debating how to finish the war in Italy. The Austro-Hungarian generals disagreed on how to administer the final offensive. Archduke Joseph August of Austria decided for a two-pronged offensive, where it would prove impossible for the two forces to communicate in the mountains.

The Battle of the Piave River began with a diversionary attack near the Tonale Pass, which the Allies easily repulsed. Austrian deserters betrayed the objectives of the upcoming offensive, which allowed the Italians to move two armies directly in the path of the Austrian prongs. The other prong, led by general Svetozar Boroević von Bojna initially experienced success until aircraft bombed their supply lines and Italian reinforcements arrived.

The decisive Battle of Vittorio Veneto

To the disappointment of Italy's allies, no counter-offensive followed the Battle of Piave. The Italian Army had suffered huge losses in the battle, and considered an offensive dangerous. General Armando Diaz waited for more reinforcements to arrive from the Western Front. By October 1918, Italy finally had enough soldiers to mount an offensive. The attack targeted Vittorio Veneto, across the Piave. Though Austrian soldiers fought viciously, the superior numbers of the Allies overwhelmed them. The Italians broke through a gap near Sacile and poured in reinforcements that crushed the Austrian defensive line. On November 3, 300,000 Austrian soldiers surrendered. The Battle of Vittorio Veneto heralded the dissolution of the Austro-Hungarian Army as an effective fighting force, and also triggered the disintegration of Austria-Hungary. During the last week of October, declarations made in Budapest, Prague, and Zagreb proclaimed the independence of their respective parts of the old empire. On October 29 the imperial authorities asked Italy for an armistice, but the Italians continued to advance, reaching Trento, Udine, and Trieste. On November 3, Austria-Hungary sent a flag of truce to the Italian Commander to ask again for an Armistice and terms of peace. The terms were arranged by telegraph with the Allied Authorities in Paris, communicated to the Austrian Commander, and were accepted. The Armistice with Austria was signed in the Villa Giusti, near Padua, on November 3, and took effect on November 4, at three o’clock in the afternoon. Austria and Hungary signed separate armistices following the overthrow of the Habsburg Monarchy and the collapse of the Austro-Hungarian Empire.
