I was watching the Military Channel this moring while getting ready and they talked/showed the tactics Wellington used against Napolean "Bonie" Bonapart. Wshen he had his forces lie down behind the crest of the hill, it reminded me of the tactics Morgan used against the Brit Dragoons at Cowpen (in South Carolina) in 1780 (35 years before Waterloo). It was tried again at Guilford Courthouse a little bit later.

Is this the case of the Brit army seeing tactics that worked against them and adopting them?
Just curious what all y'all military historians/history buffs think.
