Ambrosio's early actions in World War II included leading the Italian offensive during the
Invasion of Yugoslavia in 1941. After brief but heavy fighting, the
2nd Army under his command attacked from the north reaching
Ljubljana and the outskirts of
Zadar by April 11. On 15 April, Ambrosio conquered
Split and
Kotor. By 17 April Ambrosio controlled the Dalmatian coast. Mussolini rewarded his success by appointing Ambrosio
Chief of Staff of the Italian Army in January 1942. When Mussolini became unable to stand against
Adolf Hitler, Ambrosio supported his removal from power. After Mussolini's
fall in July, Ambrosio continued as Chief of Staff in
Pietro Badoglio's military government. In September, Ambrosio helped negotiate an armistice with the Allies. The negotiations took longer than expected and allowed the Germans time to occupy much of Italy. Ambrosio was eventually demoted to Inspector-General of the army by Badoglio in November 1943 on the insistence of the Allies, who did not trust him. ==Personal life==
