Sio is a mud cemetery. Those who have already given their lives for the emperor compete for mire space with those who intend to. Bizarre forktailed American planes dive out of the sun every day to murder them with terrible glowing rains of cannon fire and the mind-crushing detonations of bombs, so they sleep in open-topped graves and only come out at night. But their pits are full of reeking water that chums with hostile life, and when the sun goes down, rain beats them, carrying into their bones the deadly chill of high altitudes. Every man in the 20th Division knows that he will not leave New Guinea alive, so it remains only to choose the method of death: surrender to be tortured, then massacred by the Australians? Put grenades to their heads? Remain where they are to be killed by the airplanes all day, and all night by malaria, dysentery, scrub typhus, starvation, and hypothermia? Or walk two hundred miles over mountains and flooding rivers to Madang, which is tantamount to suicide even when it is peacetime and you have food and medicine…?
But that is what they are ordered to do. General Adachi flies to Sio—it is the first friendly plane they have seen in weeks—and lands on the rutted septic field that they call an airstrip, and orders the evacuation. They are to move inland in four detachments. Regiment by regiment, they bury their dead, pack up what is left of their equipment, hoard what little food is left, wait for dark, and trudge towards the mountains. The later echelons can find their path by smell, following the reek of dysentery and of the corpses dropped behind the pathfinder groups like breadcrumbs.
The top commanders stay to the end, and the radio platoon stays with them; without a powerful radio transmitter, and the cryptographic paraphernalia that goes with it, a general is not a general, a division is not a division. Finally they go off the air, and begin breaking the transmitter down into the smallest pieces they can, which unfortunately are not all that small; a divisional radio transmitter is a powerful beast, made for lighting up the ionosphere. It has an electrical generator, transformers, and other components that cannot be made light. The men of the radio platoon, who would find it difficult to move even the weight of their own skeletons over the mountains and across the surging rivers, will carry the additional burdens of engine blocks, fuel tanks, and transformers.
And the big steel trunk with all of the Army codebooks. These books were heavy as death when they were bone dry; now they are sodden. To carry them out is beyond imagining. The rules dictate that they must therefore be burned.
The men of the 20th Division's radio platoon are not much inclined to humor of any kind at the moment, not even the grim sardonic humor universal among soldiers. If anything in the world is capable of making them laugh at this moment, it is the concept of trying to construct a bonfire out of saturated codebooks in a swamp during a rainstorm. They might be able to burn them if they used a lot of aviation fuel—more than they actually have. Then the fire would produce a towering column of smoke that would draw P-38s as the scent of human flesh draws mosquitoes.
Burning them can't be necessary. New Guinea is a howling maelstrom of decay and destruction; the only things that endure are rocks and wasps. They rip off the covers to bring home as proof that they have been destroyed, then pack the books into their trunk and bury it in the bank of an especially vindictive river.
It's not a very good idea. But they have been getting bombed a lot. Even if the shrapnel misses you, the bomb's shock wave is like a stone wall moving at seven hundred miles an hour. Unlike a stone wall, it passes through your body, like a burst of light through a glass figurine. On its way through your flesh, it rearranges every part of you down to the mitochondrial level, disrupting every process in every cell, including whatever enables your brain to keep track of time and experience the world. A few of these detonations are enough to break the thread of consciousness into a snarl of tangled and chopped filaments. These men are not as human as they were when they left home; they cannot be expected to think clearly or to do things for good reasons. They throw mud on the trunk not as a sane procedure for getting rid of it but as a kind of ritual, just to demonstrate the proper respect for its lode of strange information.
Then they shoulder their burdens of iron and rice and begin to strain up into the mountains. Their comrades have left a trampled path that is already growing back into jungle. The mileposts are bodies—by now just stinking battlegrounds—disputed by frenzied mobs of microbes, bugs, beasts, and birds never catalogued by scientists.
