Shaftoe didn't believe a word of it at first. He pegged it as some kind of British humor thing, some kind of practical joke/hazing ritual. In general he doesn't know what to make of the Brits because they appear (in his personal observation) to be the only other people on the face of the earth, besides Americans, who possess a sense of humor. He has heard rumors that some Eastern Europeans can do it, but he hasn't met any of them, and they don't have much to yuk it up about at the moment. In any case, he can never quite make out when these Brits are joking.
Any thought that this was just a joke evaporated when he saw the quantity of armaments they were being issued. Shaftoe has found that, for an organization devoted to shooting and blowing up people on a large scale, the military is infuriatingly reticent about passing out weapons. And most of the weapons they do pass out are for shit. It is for this reason that Marines have long found it necessary to buy their own tommy guns from home: the Corps wants them to kill people, but they just won't give them the stuff they need!
But this Detachment 2702 thing is a whole different outfit. Even the grunts are carrying trench brooms! And if that didn't get their attention, the cyanide capsules sure did. And the lecture from Chattan on the correct way to blow your own head off ("you would be astonished at how many otherwise competent chaps botch this apparently simple procedure").
Now, Shaftoe realizes that there is an unspoken codicil to Chattan's orders: oh, yeah, and if any of the Italians, who actually
Actually, Shaftoe doesn't mind this mission. It is certainly no worse than Guadalcanal. What bothers him (he decides, making himself comfortable on the sacks of mysterious trash, staring up at a crack in the tarp) is not understanding the purpose of it all.
The rest of the platoon may or may not be dead; he thinks he can still hear some of them crying out, but it's hard to tell between the pounding of the incoming surf and the relentless patter of the machine gun. Then he realizes that some of them must be alive or else the Nips would not continue to fire their gun.
Shaftoe knows that he is closer to the gun than any of his buddies. He is the only one who has a chance.
It is at this point that Shaftoe makes his Big Decision. It is surprisingly easy--but then, really stupid decisions are always the easiest.
He crawls along the log to the point that is closest to the machine gun. Then he draws a few deep breaths in a row, rises to a crouch, and vaults over the log! He has a clear view of the cave entrance now, the comet-shaped muzzle flash of the machine gun tesselated by the black grid of the net that they put up to reject incoming grenades. It is all remarkably clear. He looks back over the beach and sees motionless corpses.
Suddenly he realizes they are still firing the gun, not because any of his buddies are alive, but to use up all of their excess ammunition so that they will not have to pack it out. Shaftoe is a grunt, and understands.
Then the muzzle swings abruptly towards him--he has been sighted. He is in the clear, totally exposed. He can dive into the jungle foliage, but they will sweep it with fire until he is dead. Bobby Shaftoe plants his feet, aims his .45 into the cave, and begins pulling the trigger. The barrel of the machine gun is pointing at him now.
But it does not fire.
His .45 clicks. It's empty. Everything is silent except for the surf, and for the screaming. Shaftoe holsters his .45 and pulls out his revolver.
The voice that is doing the screaming is unfamiliar. It's not one of Shaftoe's buddies.
A Nipponese Imperial Marine bolts from the mouth of the cave, up above the level of Shaftoe's head. The pupil of Shaftoe's right eye, the sights of his revolver, and this Nip are all arranged briefly along the same line for a moment, during which Shaftoe pulls the trigger a couple of times and almost certainly scores a hit.
The Imperial Marine gets caught in the netting and plunges to the ground in front of him.
A second Nip dives out of the cave a moment later, grunting incoherently, apparently speechless with horror. He lands wrong and breaks one of his leg bones; Shaftoe can hear it snap. He begins running towards the surf anyway, hobbling grotesquely on the bad leg. He completely ignores Shaftoe. There is terrible bleeding from his neck and shoulder, and loose chunks of flesh flopping around as he runs.
Bobby Shaftoe holsters his revolver. He ought to shoulder his rifle and plug the guy, but he is too confused to do anything for the moment.
