"Back to Four!" called the doctor. "Forget about Two and Three. But make sure the door is tight. Scrape off the rust, hammer it loose, do what you can. And hurry !" Two and Three were saddle tanks and if one should remain airtight while the other did not, there would be a strain set up in the badly weakened fabric of the ship, a strain which might very well crack open the entire system of tanks. Allowing both tanks to flood would equalize the strain on the forward wall of Four. It would also, Wallis reminded himself, double it! Like the other watertight doors between the tanks, this one had been dogged open to facilitate the free circulation of air, and like the others it was practically rusted solid in that position. They had to hammer at the door and its surrounding with scrap metal in an effort to dislodge the gritty incrustation that could be felt (but could not be seen) covering everything, then to scrape frantically with bits of metal and wood and even their fingers to free hinges and coaming of the clogging rust. They used files that were themselves little more than bars of rust, and the damage they inflicted on each other amid the darkness and confusion was severe although not, it seemed, immediately disabling. Yet, all the time the water rose steadily, spraying into Four through the supposedly watertight door from Two. When they closed the door they were working on to check the fit, water built up so quickly behind it that the efforts of all of them were needed to push it open again. Then came the time when they could not force it open. Water streamed from its edges in a steadily increasing volume and ran aft along the deck. They were forced to retreat again. The door into Seven was in better condition, since it was closed frequently to contain the heat generated by the lighting in the garden there. Number Seven held, even though it was not perfectly tight either. Nevertheless, it allowed them time to stop and think. It gave them a chance to take stock, to realize how much was lost to them, and to adjust to their new, harsher and, it was plainly obvious, all too impermanent world. The other two seniors were dead. The elder Dickson had been trapped in Number One and Wallis's brother had died during the confusion in Four. It was difficult to say what exactly had happened by touch alone, but it seemed that his brother had tripped in the darkness -- a lot of gear had changed its position, moved both by the water and by the people working on the doors -- and hit his head with sufficient force for him to lose consciousness, and he had drowned quietly in a few inches of water. They could have moved the body aft, but the doctor had asked that it be left where it was. The entrance to Richard's Hole was under water, as was the generator, the garden, and most of the bedding. All the tanks forward of Seven were flooded or inaccessible. Within the space of a few hours their world had shrunk by half. Whereas before there had been miserable cold and dampness, there was now the added misery of flooding. The water was more than a foot deep around the connecting doors and, because of the attitude of the ship, it was almost waist-deep in the sternmost tank, Number Twelve. With the generator gone and the garden destroyed by sea water there was no possibility of producing light or heat, or of recycling air or distilling drinking water. With half their world had gone half their air supply. There were odd scraps of wood and metal, even a few electric light bulbs, and enough food. They would not starve. The food supply, while meager, would far outlast the water and air. Full circle, thought Wallis. Five survivors in a sunken ship, Wallis thought sadly. Two young couples and an aging, bad-tempered doctor facing death because there wasn't enough air or drinking water. But this time there was no possibility of continued survival, for their resources were gone and there was no scope in which to exercise their ingenuity, nothing with which they could build a world for themselves, and no means of extending their lives by more than a few weeks. This was, finally, the end of the world. They should all try to accept that fact, stop struggling, and try to adopt a more philosophical attitude to their approaching end. "Is anyone badly hurt?" Wallis asked gently. There were numerous cuts and bruises, but nothing serious. He advised them to bathe the wounds in a saline solution -- there was plenty of it about -- to remove dirt or rust, and warned them not to cover the areas until a scab had formed, because of the danger of septicemia from the hair coverings. He also suggested that they move to Richard's Rooms with as much bedding as could be salvaged, that being the only relatively dry spot in the ship. They could wave the damp bedding around their heads to dry it off, and the exercise would help keep them warm. . . . That night they did not play the Game. Instead they huddled together for warmth, wriggling to get closer together and farther away from the cold, damp bedding and even colder deck, which sucked the heat remorselessly from them, and cursed because they could do neither. It was the first time the Game had not been played, the first night that their phenomenal minds and tremendous memories had not been able to lift them out of the discomfort of the here-and-now and into the bright, happy worlds of music and fiction and history, even of ship history. It was the first time that the memories of recent events had raised such a terrible barrier, a barrier cutting off all retreat into the past, the future, or even the might-have-been. It was perhaps the first time that they all realized that there was no hope, that there never had been any hope. The commander lay shivering and cursing and listening to the sounds of dripping water and the creaking of their rusty, disintegrating world for a very long thne; then he said, "You know, with five of us occupying this small cabin there is bound to be a lot of breath condensation. We can collect it and eke out the drinking water. It might even be possible to salvage enough for a small generator -- a hand model, of course, because of the small space available, and, if nothing else, building it will occupy our minds. We'll have to make a determined effort to attract attention again, by banging on the hull in relays. This will help warm us up as well as . . . as . . ." He trailed off into silence and the silence remained unbroken. You stupid, cowardly fool! he raged silently at himself. Don't you know when to give up! On the surface, in the War Room of a building many times older than the sunken tanker, other men were discussing the question of survival. "Is it agreed that we use anti-missiles, proximity-fused, with chemical warheads?" said the officer at one side of the table. "Our anti-missiles were intended for use against ground-launched ICBMs, and will therefore not be effective until the enemy has penetrated to within one hundred miles of the surface. Do we also agree that to use nuclear warheads in these circumstances would hurt us more than the enemy, assuming that the enemy ships are in fact susceptible to damage and are not equipped with, uh, super weapons of offense or defense?" There was no head to the table. The officers seated around it were the top military men of their respective governments and bore equal rank despite the fact that some of their uniforms were heavy with ribbons and gold braid while others were almost ostentatiously simple and unadorned. It was one of the latter who spoke next, using his interpreter. "I do not understand their strategy," he said. "To send in a small advance force to test our defenses is good. To wait nearly a year, which is the time our observatories tell us will be required for the remainder of their fleet to reach earth, before committing the main force is bad tactics. It gives us too much time to prepare." "Not enough time, by far," said another. "With luck we will be able to deal with the first wave using all of our present stock of anti-missiles, but a year is not enough to prepare for the main invasion!" "The whole idea of an invasion from space is tactically unsound," a quieter voice broke in. "Perhaps this is an assumption we were too quick to make. The aliens have begun to send what appear to be signals, a continuous audio-frequency note, containing patterned interruptions, like Morse in reverse. If we assume instead that . . ." His voice was drowned suddenly in a flood of objections, which condensed after a few minutes into the quiet, sardonic voice and objections of one man. "There is no peaceful solution to this problem, General," he said. "At their present rate of deceleration, the vanguard of the enemy fleet is just fifty-six hours away. If they were broadcasting messages of peace and good will in perfect English with an accent of one of your better public schools, we could act no differently: it would be the same as saying that Overlord had been mounted so that the men could picnic on the Normandy beaches. Their presence and behavior here is plainly, unmistakably hostile." "Our launching sites aren't positioned for an attack from space," said another voice worriedly. "But it would be good tactics for them to orbit a few times to get a closer look at their objectives, and perhaps do a little softening-up, in which case all our sites would get a crack at them as they went over. The thing bothering me is if they try to soften us up with H-bombs -- " "Not likely, I would say," another voice broke in. "The size of the fleet alone would make it seem certain that they intend landing and that they should not want to dirty up their bridgehead with fallout. Of course, we may have been under surveillance without knowing it for a long time. They might know enough about our physical make-up to use nerve gases or bacteria -- " "No matter what they send, we'll have to soak it up," the first officer broke in. "If they come straight in so that the majority of our launchers cannot be brought to bear, we'll have to hit them with jets and ground artillery. If they become established we may be forced to use nuclear weapons, which would be very bad if the area were densely populated. But if they make the mistake of going into orbit, especially if it is a low, bombing orbit -- " ". . . We'll clobber them," someone finished for him. The vanguard of the Unthan fleet did not go into orbit. It did not have the fuel reserves to do so. In the flagship's forward screens the surface features of the target world -- layers of water vapor hanging in the gas envelope, details of the drab, useless land masses and the tremendous blue oceans -- grew steadily larger and crawled over the edges of the picture. The casualties they suffered were reflected in the computer room, where lights went out quietly and guidance systems died at the other end and from where it was difficult to realize the true extent of the devastation and death taking place all around them. Looking out of the direct vision panels it was hard for Gunt to realize that anything at all was happening or that there were beings down there doing their best to kill him . . . until the detectors showed a missile climbing towards them, closing fast. It was over so quickly that by the time his lagging brain realized that he was about to die they had been reprieved and he was free to work out what had actually happened. Obviously the missile's target-seeker had equated size with importance and turned it at the penultimate instant onto the larger food ship, which had been keeping close station on them for so many generations. The missile must have penetrated the hull before exploding, because the ship seemed to jerk apart silently as the force of the explosion was transmitted through the water to every single corner of its structure. It opened out slowly, hurling great masses of metal, gobbets of coldly steaming water, and the twitching bodies of the food animals in all directions. Gunt cringed as several times debris narrowly missed the flagship, but unknown to him, the expanding sphere of wreckage was confusing the ground radar, making it impossible to detect a whole ship among the falling pieces, so it saved his ship. The flagship dived through the cloud layer into heavy precipitation and strong winds and near darkness, to hang poised for an instant above the storm-tossed sea before sliding quietly below the surface. Now they would have to spend precious time hunting for shelter and hope that their movements and eventual hiding place did not register on the detecting instruments of the enemy. Gunt intended to camouflage the ship, if he had time, and arrange a system of communications, but before that happened his colonists would form into their preselected survival groups and scatter themselves up and down this rocky, beautiful subcoastline. They would not scatter too far because the captain wanted to know what to expect in the way of weapons and general nastiness from the enemy so that he, or the person who survived him, could tell the later arrivals what to expect. They were little more than experimental animals, Gunt thought sickly, being tested to destruction. Captain Heglenni and her females had been given a much more positive assignment, that of obtaining specimens of the enemy life-form together with whatever artifacts and mechanisms became available for study. It was accepted that Heglenni would have to kill the specimens and take the mechanisms by force, and that the war was only just beginning, but Captain Gunt did not allow himself to think about that too much. The future was too horrible for any sane person to dwell in it mentally for any longer than was necessary. His ship was down, safely. XXII More than eighty per cent of the Unthan vanguard escaped the anti-missiles and reached the ocean safely. The earth defenses, with no previous experience of invasion from space, had deployed as best they could against expected landings in force in desert or thinly populated areas. They were thrown badly off balance by the fact that the enemy did not make a single preliminary orbit, that instead of a concentration of force they came down in single units scattered all over the surface of the globe, and that the landings did not take place on land but in the sea around the world's coastlines. Except for one ship, that was.
