Napoleons treatment of Dupont is almost as bad as the sufferings of the French and Allied (read German memoirs of Condfederation of the Rhine officers) by the Spanish and dare I say English, who turned two blind eyes on apparent mistreatment of POWs and letting POW starve to death.
There was no reason that Dupont got treated as he was. And he was even treated badly before Baylen, having earned the Marshal's baton more than once - there is a sort of disregard of Dupont's excellent service before Baylen.
Pozzolo, Hasslach, Halle - to name only a few battles and clashes were Dupont excellend himself.
Dupont fits well in the line of other excellent officers as Barnadotte or Moreau - all victims of Napoleonic propaganda.
