MTO - Italy: One month after the surrender of Italy's army, Italian Prime Minister Pietro Badoglio declares war on Germany, its former Axis partner, and joins the battle on the side of the Allies.
Italian Prime Minister Pietro Badoglio (center) declares war on Germany
With Mussolini deposed from power and the collapse of his fascist government in July, Gen Pietro Badoglio, Mussolini's former chief of staff and the man who had assumed power in Il 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 08 Sep 43 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.
On the day of Italy's surrender, Hitler launched Operation AXIS, the occupation of Italy. They began taking all Italian troops prisoner within the areas in which they were stationed. Any and all Italians that resisted were slaughtered. One of the goals of Operation AXIS was to keep Italian navy vessels out of the hands of the Allies.
The new Badoglio government had wished to merely stop fighting, but Germany's actions made that an impossibility. On this day, Badoglio announced that Italy would continue fighting, but now on the side of the Allies.
The Allied operation to capture Rome from the Germans was extremely slow going. But when it was finally over, and Rome was once again free, General Badoglio would take yet one more step in freeing Italy from its fascist past - he would step down from office.
