On October 13, 1943, the government of Italy declares war on its former Axis partner Germany and joins the battle on the side of the Allies.
With Mussolini deposed from power and the collapse of the fascist government in July, Gen. Pietro Badoglio, Mussolini’s former chief of staff and the man who had assumed power in the Duce’s stead by request of King Victor Emanuel, began negotiating with General Eisenhower regarding a conditional surrender of Italy to the Allies. It became a fact on September 8, with the new Italian government allowing the Allies to land in Salerno, in southern Italy, in its quest to beat the Germans back up the peninsula.
