False Flags:
The use of false flags to gain a tactical advantage prior to battle, or to enter an enemy port under cover, is perfectly legal. You are required to hoist your true flag (or at least, a flag hostile to the target) before opening fire.
Forts and ships may see you change flag if you are within visual range. Be warned, forts can see a long way. If a fort once sees you under a hostile flag, it will remember and it will recognise you. Therefore if you intend to enter a hostile port under a false flag, be sure to hoist your false flag well away from the coast.
If you have been recognised, there are several ways to avoid further recognition:
- Make peace with the nation, even if only for long enough to carry out your business in port and leave safely.
- Acquire a different class of ship. The fort remembers your ship, therefore if you no longer have a ship of that type, the fort will no longer recognise you. (It is not sufficient to repaint the ship, or to give it to a subordinate officer. If the fort sees that ship, or any ship of the same type, anywhere in your fleet, you will be recognised.)
- Attack and capture the fort. The fort's records will be lost while you are plundering it.
