thanks for clearing that up. I also noticed there are a couple of planes nearby. can I use those for both the sea battle and the assault? will the AA gun on land also fire when the planes take part in the sea battle or only when they take part in the assault?

I won’t have a rulebook at hand for a while, so can anyone please tell me if it’s possible to conduct an amphibious assault and a sea battle in the same sea zone simultaneously? my opponent has a fleet in front of gibraltar, I’d like to knock out that fleet and take gibraltar (no bombardment) at the same time. we’re playing AAE1940.
