When World War II broke out on September 1, 1939 and ended on August 15, 1945, Germany did not surrender until the last minute, while Italy, germany's ally, surrendered on October 13, 1943. In 1943, the Soviet Union had just begun to push back germany, at this time the situation on the Soviet-German battlefield had not deteriorated, the German army was still sure to defeat the Soviet Union, although Japan lost the Battle of Midway, but the whole of Southeast Asia was still in the hands of Japan, according to the reason, Italy could not surrender at this time, then why Italy, at this point in time, surrendered so quickly.
At the beginning of the war, there was anti-war sentiment in Italy as the war continued, the German army could still stabilize the defensive line, France, Poland was also in the German occupation, Italy actually surrendered at this time, and lost a large number of overseas territories, at this time the Allies had just launched the Sicily Campaign, Italy did not reach the point of exhaustion, but what surprised people was that as soon as the Allied forces landed, the Italian fascist regime fell, and basically did not do anything to resist. The newly formed Provisional Government arrested Mussori and prepared to surrender to the Allies.
As soon as Germany saw the surrender of its fascist allies, it immediately began preparations for the Axis plan.
On September 8, 1943, Germany entered rome, the capital of Italy, in just two days, and on September 12, Hitler ordered a special forces to rescue the imprisoned Mussori, and subsequently became the Italian Socialist Republic, Italy from Germany's allies complete puppet regime,
On 19 September, the Germans captured a large number of Italian generals and disarmed all Italian allies in Europe, and the Italian navy fled in large numbers, leaving only five warships in the ports of the Kingdom of Romania detained.
Axis planned german captives.
The Italian army stationed in France was 8,722 men
Native Italian 518022
164986 people in the Yugoslav region
Greek mainland and Aegean islands 2650000
Germany, as well as the Kingdom of Romania and Europe, captured about 50,000 men, took a total of 1 million soldiers, and killed another 20,000, not including the southern tip of Italy.
When Italy surrendered, it also had a large number of guns and light and heavy artillery, not including Italy, and it is conceivable that when Italy surrendered, the army still had a lot of combat strength.
Years of war brought the Italian economy to the brink of collapse. Food is scarce across the country, the black market is rampant, and the people are not happy. The army was also in a state of "collapse", with a serious shortage of troops, low morale, and a split within the Italian Fascist Party, and on the afternoon of 3 September 1943, in Sicily, the Allied representative General Smith and the Italian representative General Castellano were formally authorized to sign a short armistice with the effective date of Salerno Landing Day. At that time, Italy will announce its surrender and withdraw from the war. Thus, one of the main aims of the Allied invasion of italy, the expulsion of Italy from the war, was achieved before the attack began.
