Title pretty much says it all. What is the latest date Indians could plausibly wipe out one of the original thirteen colonies?
By wiped out, I mean everyone either killed, captured, or forced flee the bounds of the colony. No time-travelers or space lizards, of course, (since this isn't in the ASB section) just Indians and possibly plausibly available Europeans, with the heavy lifting being done by Indians.
The wipe-out doesn't have to be permanent. If the territory involved gets reoccupied in twenty years it still counts. Reoccupation in ten years should probably be the minimum though.
