One thing I can't work out is how I can help the 13 colonies when they are attacked ( playing as British on Hard/Hard). They are my proctectorate so I feel I shoul try to help them.

If I move a fleet into their only port ( New York ) I get a message asking if I want to declare war on them. That only leaves two options , take the very long way around canada or attack the French in Quibec.

Has anybody come up with a better method ( am I missing something ) ?

I must add , having a very enjoyable time overall. The first time my Red Coats advanced in line formation towards the enemy was incredable.
