“ Mitchell Sanders was right. For the common soldier, at least, war has the feel-the spiritual texture-of a great ghostly fog, thick and permanent. There is no clarity. Everything swirls. The old rules are no longer binding, the old truths no longer true. Right spills over into wrong. Order blends into chaos, love into hate, ugliness into beauty, law into anarchy, civility into savagery. The vapors suck you in. You can't tell where you are, or why you're there, and the only certainty is overwhelming ambiguity. ”
