Yes, but I mean making sure that the British land in vaguely the right place, making a ton of troops but a stable economy, even with no large cities... it's a bit complicated.
Perhaps the best way would be to have wonders that give you free upkeap for N units placed in strategic cities?
The AI knows how to take wonders.
The reason why I suggested they be world wonders is becouse:
1. They can not be destroyed when the city is captured (normal buildings can) and
2. The AI seems to prioritise taking cities with wonders (or maybe that is just my gaming experiance)
