I've been contemplating how I want to write some of the battle sequences in my novel. I'm writing an epic fantasy which I want to have a light-hearteness about it as a kind of undertone throughout what will be a very deep and psychology story during it's major events. I think I can get the balance right through almost all situations, but with the battle sequences I'm scratching my head a little bit. I can write it to be a very real experience and try to resonate the atmosphere and emotions of real battles; for example I think Saving Private Ryan and Band of Brothers often get praised for that portrayal of the what the battles in WII were really like and their real emotions and consequences. Or, I can write it much more light-hearted, with people running towards water while on fire, soldiers having trivial arguments while firing at the enemy, people running away from vehicles shouting "****!" as it's about to explode, that kind of thing. For the particular fight scene right now, it focuses on a group of soldiers that I'm trying to introduce as a group of mates, bickering and mocking eachother with dry sarcastic humour. I'm also trying to point out that these guys are total, self-confident pro's (better than normal humans) who are just doing something they always do and have done for 10 years. It's also at a point in the story where nothing major has happened, and these guys are pretty care-free. So I'm inclined to make this battle a little light-hearted. I'm confident I can write like this without making it too cheesy, but I'm wondering if I should, and whether publishers or audiences will look down on treating something like a serious battle in a major war (it is an important battle, but the soldiers I'm following don't treat it very importantly because they're so confident and self-assured) so light-hearted. I'm also wondering if it's possible to have different war battles in the novel have different moods or if that's a bad idea. It's entirely possible that later in the story I have a battle sequence that's much more tied to the plot and during or after a very traumatic event for the Main Characters, like immediately following the death of a major character or the revelation of some seriously bad news, when the main characters are insecure, traumatized, stressed or vulnerable in some way, and thus I might write it very gritty with much more realistic emotions and descriptions of what a real battle means. So in a way I'ed kind of link the mood of the battle to the mood of the overall situation. But what do you think? I can think of battles were alot of the actual fighting is kind of light-hearted; The final battle at Hogwarts comes to mind in HP: Deathly Hallows, where comical events are happening at every turn despite Harry being seriously stressed about the severity of the situation. Do you think it's bad and too unrealistic to treat battles in this way?
