all land units retreat to a single adjacent territory, while the air units remains in the territory.
The only way you did something illegal is if you retreated your air units somewhere, and then moved them to S. Italy.
If I take a battleship and strategic bomber against an enemy cruiser and sub, and my opponent does not submerge, how does combat proceed? Do I roll the battleship and bomber at the same time or separately? Meaning, if I roll at the same time and get one hit, he chooses to lose the sub or cruiser (since bombers can’t hit subs)? Or, do I roll separately, and if the bomber hits he MUST lose the cruiser?
You should roll them separately.
