With the Austro-Hungarian offensive stopped by Diaz at the Second Battle of the Piave River, a lull in fighting ensued on the Italian front as both sides brought up their logistical elements. Orlando ordered an investigation into the causes of the defeat at Caporetto, which confirmed that it was the fault of the military leadership. While he continued to reform the military, he refused demands from both sides of the political aisle calling for mass trials of generals and ministers. The Italian front stabilized enough under his leadership that Italy was able to send hundreds of thousands of troops to the Western Front to buttress their allies while themselves preparing for a major offensive to knock Austria-Hungary out of the war. This offensive materialized in November 1918, the Italians launched the Battle of Vittorio Veneto and routed the Austro-Hungarians, a feat that coincided with the collapse of Austro-Hungarian Army and the end of the First World War on the Italian Front, as well as the end of the Austro-Hungarian Empire. The fact that Italy recovered and ended up on the winning side in 1918 earned for Orlando the title "Premier of Victory."
