Battle of Vittorio Veneto - Battle

Battle

After the battle of the Piave, General Armando Diaz, the Italian commander in chief, despite aggressive appeals by Allied commanders, deliberately abstained from offensive action until Italy should be ready to strike with success assured. In the offensive he planned, three of the five armies lining the front from the Monte Grappa sector to the Adriatic end of the Piave were to drive across the river toward Vittorio Veneto, so as to cut communications between the two Austrian armies opposing them.

Allied forces totaled 57 infantry divisions, including 51 Italian, 3 British, 2 French, 1 Czechoslovak, and a token American regiment, along with supporting arms. The Austrians fielded an Army of roughly equal size, but one that was demoralized, with 52 infantry divisions and an inferior number of artillery pieces. On 24 October, the anniversary of the Battle of Caporetto, the offensive opened. A first attack in the Monte Grappa sector was launched to attract the Austrian reserves. The flooding of the Piave prevented two of the three central armies from advancing simultaneously with the third; but the latter, under the command of Lord Cavan, after seizing Papadopoli Island farther downstream, won a foothold on the left bank of the river on 27 October. The Italian reserves were then brought up to exploit this bridgehead. Svetozar Boroević von Bojna, the Austro-Hungarian commander, ordered a counter-attack on the Italian bridgeheads on the same day, but his troops refused to obey orders, a problem confronting the Austrians from that time on, and the counter-attack failed.

After crossing the Piave River, the Eighth Italian Army, led by General Enrico Caviglia, took Vittorio ("Veneto" was added to the name only in 1923) and advanced in the direction of Trento, threatening to block the retreat of Austrian forces.

On 28 October Czechoslovakia declared independence from Austro-Hungary. The next day the South Slavs proclaimed independence, and on 31 October Hungary withdrew from the union, officially dissolving the Austro-Hungarian state. On 28 October, under these new political and military conditions, the Austro-Hungarian high command ordered a general retreat. As already mentioned, Vittorio Veneto was seized the next day by the Eighth Italian Army, which was already pushing on to the Tagliamento river. Trieste was taken by an amphibious expedition on 3 November.

The 11th Italian army, commanded by French General Jean Graziani, continued to advance, supported on the right by the 9th Army. The result was that Austria-Hungary lost about 30,000 casualties and between 300,000–500,000 prisoners (50,000 by 31 October 100,000 by 1 November, 428,000 by 4 November). The Italians suffered 37,461 casualties (dead and wounded), including 145 French and 374 Britons.

On 29 October the Austro-Hungarians asked for an armistice. On 30 October 1918 the Austro-Hungarian army was split in two. The armistice was signed on 3 November at 3:20 p.m., to become effective 24 hours later, at 3 p.m. on 4 November.

The Austrian command ordered its troops to cease hostilities on 3 November. Following the signing of the armistice, Austrian General Weber informed his Italian counterparts that the Imperial army had already laid down its weapons, and asked to cease combat immediately and to stop any further Italian advance. The proposal was sharply rejected by the Italian General Badoglio, who threatened to stop all negotiations and to continue the war. General Weber repeated the request. Even before the order to cease hostilities, the Imperial Army had already started to collapse, beginning a chaotic retreat. Italian troops continued their advance until 3 p.m. on 4 November. The occupation of all Tyrol, including Innsbruck, was completed in the following days.

Under the terms of the Austrian-Italian Armistice of Villa Giusti, Austria-Hungary’s forces were required to evacuate not only all territory occupied since August 1914 but also South Tirol, Tarvisio, the Isonzo Valley, Gorizia, Trieste, Istria, western Carniola, and Dalmatia. All German forces should be expelled from Austria-Hungary within 15 days or interned, and the Allies were to have free use of Austria-Hungary’s internal communications. They were also obliged to allow the transit of the Entente armies, to reach Germany from the South.
