So I'm pretty sure this has likely been done to death, but what would the postwar colonies look like if the American Revolution got crushed before it could get off the ground? Specifically, who among the prominent figures would be hanged as traitors, who might be spared, and what would the British colonial governance look like?
If it helps, the POD I have in mind is that the British take a decisive victory at Bunker Hill (capturing Putnam and Prescott if you like) and demonstrate to the colonists that militia is little match for a professional army.
