In 1918, he devised the plan for the Battle of Vittorio Veneto and promoted General for exceptional merit at just 38 years. In 1920 he left the Army and became general manager of the Pirelli company. Member of Parliament from 1924, he was Under-Secretary of State for War from 1925 to November 1928. Recalled to duty, he was appointed commander of the troops in Italian East Africa from 1937 to 1939, and in the same year he was appointed vice chairman of the committee on economic and military of the implementation of the Pact of Steel with Germany. In December 1940, Cavallero was appointed Commander of the Army Corps, and Commander of the Royal Italian Army to the merits of war. From December 4, 1940 at the beginning of 1943, he was Chief of Staff General in replacement of General Pietro Badoglio and was Commander of the Army in Albania in replacement of General Ubaldo Soddu. Ugo Cavallero promoted to Marshal of Italy on 1 July 1942. After July 25, 1943, Badoglio gave orders to arrest Cavallero by accusing him of planning a fascist coup. Thanks to its status as senator, he was allowed to avoid prison and was locked up in Palazzo Madama. Thereafter he was released on the initiative of King Vittorio Emanuele III, but was arrested again in late August and detained at the Forte Boccea in Rome. On September 12, 1943 following the Armistice of Cassibile and the occupation of Rome by the German Army, he was released and transferred to the German command in Frascati, where Field Marshal Albert Kesselring offered him on behalf of Adolf Hitler the command of Italian Armed Forces who wanted to continue the war on Germany's side. Cavallero refused to take on this task. On the morning of September 14, 1943 was found dead in the garden of the Belvedere of Frascati with a gunshot wound to the right temple. On the same day was planned his move to Munich.
