Curiosity is killing me. I have to ask:
There are only twelve British cards, and most are move cards. Why don't you thumb through the handful of event cards and find the answer yourself?
It's a free internet, and you're not doing anything wrong. You're not the only person to ask this kind of question -- is there something about this game that elicits these questions more than usual?
I'd speculate that a lot of people learn 1775 on someone else's set and don't have their own, so it might be weeks before they get a chance to actually do that.
