What Wellington might have changed in the War of 1812

In this counterfactual, Wellington understands the political importance of paying for supplies and treating local populations carefully, lessons reinforced by the Peninsular War. He would be unlikely to occupy the entire American countryside and fight a sprawling guerrilla conflict. A more plausible speculative strategy would seize defensible ports such as New York or New Orleans and use them as bargaining positions. The scenario demonstrates how logistics and limited war aims could matter more than simply sending a famous commander across the Atlantic.
