"A
soldier’s perception of a battle is limited by what he can see and hear. He may see his comrades standing next to him
or, if the smoke is not too thick, the enemy across the field. He may hear the angry buzz of the Minié balls
and the roar of the cannon. But for him,
there is no grand, overarching plan where soldiers move like pieces on a
chessboard. For him the fight is
intensely personal, often reduced to two men:
himself and the enemy soldier trying to kill him." -- The Cause of Darkness
