We were discussing this some time ago and we should probanly look into it some more.
While ships can recognize false flags in real-time as you come closer, due to game engine limitations forts can not.
This can result in stupid situations where a French ship recognizes you as an enemy right under the French fort's guns and the fort does not respond at all.
That is a bit of an exploit, of course!
Simplest solution that I could suggest is to automatically hoist the player flag when you are recognized.
That should update the fort too, which seems fair enough to me.
