the erstwhile Eastern fighting. On 24 October 1917, Austrians (now enjoying decisive German support) attacked at Caporetto using new infiltration tactics; although they advanced more than in the direction of Venice and gained considerable supplies, they were halted and could not cross the Piave river. Italy, although suffering massive casualties, recovered from the blow, and a coalition government under Vittorio Emanuele Orlando was formed. Italy also enjoyed support by the Entente powers: by 1918, large amounts of war materials and a few auxiliary American, British, and French divisions arrived in the Italian battle zone. Cadorna was replaced by General Armando Diaz; under his command, the Italians retook the initiative and won the decisive Battle of the Piave river (15–23 June 1918), in which some 60,000 Austrian and 43,000 Italian soldiers were killed. The final battle was at Vittorio Veneto; after 4 days of stiff resistance, Italian troops crossed the Piave River, and after losing 90,000 men the defeated Austrian troops retreated in disarray pursued by the Italians. The Italians captured 448,000 Austrian-Hungarian soldiers (about one-third of the imperial-royal army), 24 of whom were generals, 5,600 cannons and mortars, and 4,000 machine guns. The armistice was signed at Villa Giusti on 3 November, in spite of Austria–Hungary already having disintegrated on 31 October 1918.

The Romanian Army crossed the borders of Eastern Hungary (Transylvania), and despite initial successes, by November 1916, the Central Powers formed by the Austro-Hungarian, German, Bulgarian, and Ottoman armies, had defeated the Romanian and Russian armies of the Entente Powers, and occupied the southern part of Romania (including Oltenia, Muntenia and Dobruja). Within 3 months of the war, the Central Powers came near Bucharest, the Romanian capital city. On 6 December, the Central Powers captured Bucharest, and part of the population moved to the unoccupied Romanian territory, in Moldavia, together with the Romanian government, royal court and public authorities, which relocated to Iași. In 1917, after several defensive victories (managing to stop the German-Austro-Hungarian advance), with Russia's withdrawal from the war following the October Revolution, Romania was forced to drop out of the war. Whereas the German army realized it needed close cooperation from the homefront, Habsburg officers saw themselves as entirely separate from the civilian world, and superior to it. When they occupied productive areas, such as southern Romania, they seized food stocks and
