To be honest, I’m kinda curious how medieval guys fight a night battle. It’s so dark when there’s no moon, and nobody lit a torch at all? If yes, wouldn’t a moving torch attract all kinds of flying objects?
There were probably not many fights at night, at least none that I ever heard of. Probably on a smaller scale, raids and the like, but not large battle between armies. There were probably even less fights in the night, in a forest, which is quite often the case in Battle Brothers.
