Try reading about them. The actions for the most part aside from changed names (which are then noted in the Historical Notes) are accurate for most intents and purposes.
must troll harder
its not trolling moron, it is fiction and that is fact
1: sharpe the main character wasn't real in europe, the only records of his name and rank and similar situations are a british soldier in america
2: yes the locals may be real places, but fiction can be set in real places and times, the fact sharpe is able to swap between so many theatres, some happening at the same time as another adds to the fiction
3: the depiction of certain characters, the biggest being the prince of orange and the dutch forces at waterloo is utter bollocks, most dutch officers gained experience in the french army, as did allot of older dutch troops, the prince of orange was inexperienced, but not a hated moron (unlike historically the large majority of british officers at waterloo)
sharpe IS fiction set in an historical period, its a good fiction, but to confuse it as historically correct is just plain stupid
