Allied Forces landed in Sicily

Explanation:

The Allied Forces decided to take down Italy first so that Germany is left alone and without any support further into the war. The Allies landed on Sicily in July 1943, and started to defeat the Italian army step by step. Even though the Italians had a large army, it was not well equipped and properly trained, so they were losing on every battlefield, which quickly led to their defeat. Mussolini had to resign after Italy was defeated, and that happened in October 1943.
