Very ungenerous, D'Erlons corps, Heavy cavalry corps, Old Guard all destroyed by British Musketry, Hougemont was never taken all day, yes the Prussians turned a very close fought battle into a rout but the Duke was not whipped far from it. The Duke was a very clever tactician study Salamanca or Vittoria they are far better examples than Waterloo
PS Nappy was lucky our best Regiments where in Canada kicking out some ragamuffins from down South.
