The BBC series based on Bernard Cornwell's Napoleonic war novels that revolve around the adventures of Richard Sharpe, an officer in the Rifle Regiment who's been commissioned from the ranks for heroism. I haven't seen too many of the episodes, but they seem to stick pretty close to the books - and the books are excellent in their portrayal of Regency-era England, particularly the interaction between the aristocracy that makes up most of the officers in the Army and the lower-class draftees serving in the ranks.
