I was thinking about how and when Italy was captured and converted into a Pro-Allies country. Once the Germans were pushed out of Italy and it was completely under Allied control, why did the Invasion of Normandy have to happen. It seems to me there were two other significant options available to the Allies in terms of their next move.
- Invading Austria from the South
This would have put direct pressure on Germany and put the Allies closer to Berlin and for the the first time threatened Germany directly.
- Invading France from the East
Why make a large amphibious invasion at Normandy when you can walk into Vichy France from Italy?
I have never heard or read anything about either of these options so I am curious what facts can be brought to light on them.
