Andrew Jackson
Napoleon was not overrated. I read his biography. He may have been the most competent man on the planet, ever.
MLK is definitely overrated. Many universities no longer observe President’s day, but the all observe MLK day.
Andrew Jackson gave the British the most lop sided defeat they ever suffered. They lost more men in several battles and lost nearly all in others but they also inflicted lots of casualties in all those.
At New Orleans Jackson suffered less than 50 casualties while the British suffered thousands.
