Badoglio was chief of staff from 1925 to 1940, and had the final say on the entire structure of the Armed Forces, including doctrine, selection of officers, and armaments, influencing the whole military environment. He did not oppose the decision of Mussolini and the
King to declare war on France and Great Britain. Following the Italian army's poor performance in the
invasion of Greece in December 1940, he resigned from the General Staff. He was replaced by
Ugo Cavallero. By early 1943, there was a widely held belief among the military elite that Italy needed to sign an armistice in order to exit the war. They also believed that Mussolini needed to be removed, as he was not willing to sign an armistice, nor were the Allies willing to sign an armistice with him. The two men considered to replace Mussolini were Marshal Badoglio and Marshal
Enrico Caviglia. As Marshal Caviglia was one of the few Royal Army officers who was known to dislike Fascism, the king was unwilling to have him as prime minister. Victor Emmanuel wanted an officer who was committed to continuing the Fascist system, which led him to choose Badoglio, who had faithfully served Mussolini and committed an array of atrocities in Ethiopia, but who had a grudge against Mussolini for making him the scapegoat for the failed invasion of Greece in 1940. On 8 September 1943, the armistice document was published by the Allies in the
Badoglio Proclamation, while Badoglio himself had not informed the Italian armed forces. The units of the Italian Royal Army, Royal Navy, and Royal Air Force were thus generally surprised by the change and unprepared for swift German actions to disarm them. In the early hours of the following day, 9 September 1943, Badoglio, King Victor Emmanuel, some military ministers, and the chief of the general staff escaped by car from Rome to
Pescara and then sailed on corvette "Bayonetta" to
Brindisi seeking Allied protection. == Final years ==
