Allied forces landed in Sicily

Explanation:

The Allied forces first went for Italy, as it was Germany's ally and with moving it out of the scene Germany was going to be alone in the war. This started with the landing of the Allied Forces in Sicily on July 10 1943. The Italian army was large, but it was not well equipped or trained, which led to losing battle by battle, so the Allied Forces managed to defeat Italy relatively easily. Mussolini resigned after the defeat, just few months after the landing in Sicily of the Allied Forces, or more specifically on October 13 1943.
