From where I sit, battles are hard. I’ve written my share. Sometimes I employ the private’s viewpoint, very up close and personal, dropping the reader right into the middle of the carnage. That’s vivid and visceral, but of necessity chaotic, and it is easy to lose all sense of the battle as a whole. Sometimes I go with the general’s point of view instead, looking down from on high, seeing lines and flanks and reserves. That gives a great sense of the tactics, of how the battle is won or lost, but can easily slide into abstraction.
