Tim O'Brien's "Waiting For Cacciato" and "The Things They Carried" are two of the greatest books on the war. They are considered fiction, but their great power lies how O'Brien plays off of that moulage of fact and fantasy. Here is an excerpt from "The Things They Carried":
They carried USO stationary and pencils and pens. They carried Sterno, safety pins, trip flares, signal flares, spools of wire, razor blades, chewing tobacco, liberated joss sticks and statuettes of the smiling Buddha, candles, grease pencils, The Stars and Stripes, fingernail clippers, Psy Ops leaflets, bush hats, bolos, and much more. Twice a week when the resupply choppers came in, they carried hot chow in green mermite cans and large canvas bags filled with iced beer and soda pop. They carried plastic water containers, each with a two-gallon capacity. Mitchell Sanders carried a set of starched tiger fatigues for special occasions. Henry Dobbins carried Black Flag insecticide. Dave Jansen carried empty sandbags that could be filled at night for added protection. Lee Strunk carried tanning lotion. Some things they carried in common. Taking turns, they carried the big PRC-77 scrambler radio, which weighed 30 pounds with its battery. They shared the weight of memory. They took up what others could no longer bear. Often, they carried each other, the wounded or weak. They carried infections. They carried chess sets, basketballs, Vietnamese-English dictionaries, insignia of rank, Bronze Stars and Purple Hearts, plastic cards imprinted with the Code of Conduct. They carried diseases, among them malaria and dysentery. They carried lice and ringworm and leeches and paddy algae and various rots and molds. They carried the land itself -- Vietnam, the place, the soil -- a powdery orange-red dust that covered their boots and fatigues and faces. They carried the sky. The whole atmosphere, they carried it, the humidity, the monsoons, the stink of fungus and decay, all of it, they carried gravity. They moved like mules. By daylight they took sniper fire, at night they were mortared, but it was not battle, it was just the endless march, village to village, without purpose, nothing won or lost. They marched for the sake of the march. They plodded along slowly, dumbly, leaning forward against the heat, unthinking, all blood and bone, simple grunts, soldiering with their legs, toiling up the hills and down into the paddies and across the rivers and up and down, just humping, one step and then the next and then another, but no volition, no will, because it was automatic, it was anatomy, and the war was entirely a matter of posture and carriage, the hump was everything, a kind of inertia, a kind of emptiness, a dullness of desire and intellect and conscience and hope and human sensibility. Their calculations were biological. They had no sense of strategy or mission. They searched the villages without knowing what to look for, not caring, kicking over jars of rice, frisking children and old men, blowing tunnels, sometimes setting fires and sometimes not, then forming up and moving on to the next village, then other villages, where it would always be the same. They carried their own lives. In the heat of early afternoon, they would remove their helmets and flak jackets, walking bare, which was dangerous but which helped ease the strain. They would often discard things along the route of march. Purely for comfort, they would throw away rations, blow their Claymores and grenades, no matter, because by nightfall the resupply choppers would arrive with more of the same, then a day or two later still more, fresh watermelons and crates of ammunition and sunglasses and woolen sweaters -- the resources were stunning -- sparklers for the Fourth of July, colored eggs for Easter -- it was the great American war chest -- the fruits of science, the smokestacks, the canneries, the arsenals at Hartford, the Minnesota forests, the machine shops, the vast fields of corn and wheat -- they carried like freight trains; they carried it on their backs and shoulders -- and for all the ambiguities of Vietnam, all the mysteries and unknowns, there was at least the single abiding certainty that they never be at a loss for things to carry.
