piccer18: What are keys to victory on the easiest setting?
Do all the following before you declare independence:
Make sure all your colonies, or at the very least all your coastal colonies, have a fortress.
Get rebel sentiment as high as possible in all colonies (preferably 100%) and keep it there - the higher the score, the harder it is for the Tories to capture a colony, and the more nearby troops will be upgraded to Continental Army.
Have lots and lots of artillery in every coastal colony.
Have lots and lots of dragoons outside every coastal colony. "Outside" is important - you only get the ambush bonus if you attack a Tory unit when neither your attacking unit nor the defending Tory unit is in a colony. Ideally position your cavalry on squares that force the REF troops to land on squares with a high defence bonus (which instead becomes an ambush bonus for you).
Make sure all your coastal colonies are heavily and roughly equally defended when you declare independence - if one colony is much more weakly defended than the others, the REF will land there, even if it's on the Pacific coast.
Make sure your colonies are well connected by roads so you can move troops and supplies between them quickly - if the Tories concentrate their attacks on one colony (which they probably will) you'll need to reinforce it.
