How would the War of 1812 have culminated had Wellington, immediately after winning the Peninsular War in 1814, been dispatched to America to take command of British forces fighting the Americans, including had he been in command at New Orleans in Jan 1815 ? How much better would he have done than his brother-in-law Pakenham (who was killed by an American sniper at New Orleans) did OTL ? Likewise, who could've been in charge of the Allied forces at Waterloo instead of himself, had Wellington been in America ?
