Which event happened first? 1 allied forces landed in sicily. 2 allied forces landed in normandy. 3 mussolini resigned. 4 hitler surrendered

Sicily See below.

Explanation:

This is a bit of a trick question. Germany  surrendered on VE day 1945. Hitler never did. General der Artillerie Helmuth Weidling signed an unconditional surrender on May 7, 1945. So I don't know what you do about that one.

Mussilini might have been able to survive had not the allied forces successfully invaded Sicily on the 10th of July 1943.

As it was, he was removed on July 25 1943.

The Normandy invasion occurred on 6 June 1944 almost a full year later than Sicily.

The one to occur first was the invasion of Sicily on 10 July 1943

more than 1 person for sure
