Once, I remember, we came upon a man-of-war anchored off the coast. There wasn’t even a shed there, and she was shelling the bush . . . In the empty immensity of earth, sky, and water, there she was, incomprehensible, firing into a continent. Pop, would go one of the six-inch guns; a small flame would dart and vanish, a little white smoke would disappear, a tiny projectile would give a feeble screech — and nothing happened. Nothing could happen. There was a touch of insanity in the proceeding, a sense of lugubrious drollery in the sight; and it was not dissipated by somebody on board assuring me earnestly there was a camp of natives — he called them enemies! — hidden out of sight somewhere.

Joseph Conrad, Heart of Darkness, 1902
