 :Hmm, if you're going to go down that line then we'd better explain why the tactics were different. Napoleon could afford battles where he lost 30,000 men as his armies numbered in the 100s of thousands. Wellington struggled to get 30,000 troops and could never afford to take risks. With regard to persuit, it is in good measure a feature of cavalry reserves; Wellington had few enough for use in battle let alone to keep fresh for the persuit.
