What Wellington might have changed in the War of 1812

How might the War of 1812 have changed if Wellington had commanded British forces in North America?

In this counterfactual, Wellington uses veteran command and logistics to force a battle, then offers limited peace terms instead of attempting permanent occupation.

Britain's strongest generals and much of its hard-won experience remained committed to Europe, leaving the North American war without a commander of Wellington's caliber. In this counterfactual, the American army was not ready to meet such a veteran force and might have needed to trade territory for time while reforming. Wellington's earlier experience in India and the Peninsula suggests that unfamiliar terrain and irregular resistance would not have been wholly new problems. The proposed strategy is to win a decisive battle and then offer terms the United States would accept instead of attempting an indefinite conquest. Command experience and logistics are the variables that matter in this explicitly speculative answer.
