Well,Age of Heroes would fit right in.
Possibly, patch - haven't seen it so I can't attest to the accuracy of the portrayal. I probably wouldn't use it though, simply because students tend to be more familiar with 'modern' warfare. The style of fighting was just beginning to change in the Napoleonic period - tactics were slowly shifting (the concept of skirmishers was one of those concepts - building on lessons learned during the American Revolution and the Scottish risings, among others - and made really possible by advances in technology).
Student's can read about a battle with orderly lines of infantry advancing en masse - or cavalry charges by saber wielding horsemen - but it's hard for them to really conceptualize that kind of polite and horrific warfare. Some of the Sharpe episodes bring the truth of that kind of fighting straight to them; they suddenly understand what it meant to 'stand and fire' in conditions that almost defy imagination.
We are not our ancestors - our reality is so very different than theirs. Using clips like those is one way of getting that idea across to my students and it seems to make it a little easier for them to accept that people did things that only
seem like they make no sense. It's a hurdle they need to cross so they don't get hung up on the 'huh??' factor during their examination of the past.
