The problem with spawning a new fleet every time the port is captured is you can end up with quite a few fleets hidden, though I DO like the idea.
What if the ports will spawn one fleet for each country; if Knights take a bish port, then it will spawn a fleet for the knights. The Bish keep their fleet until it's sunk. If the Bish then take the port BACK they don't get a new fleet until the old one gets killed.
That keeps the theoretical limit to three fleets per port, with two of them living on borrowed time.
This also eliminates the advantage of hiding a fleet; you're not hurting the guys who overran your port, and a cowering fleet is the same as no fleet at all. On the other hand, you can keep it away from shore and use it as an airfield, not entirely unlike carrier tactics in the early 1940s...pity bar dar and dot dar will give it's rough position away.
Aw, well. Nothing's perfect
