James White - Major Operation

But the Lieutenant could not dig in because the bubbles roaring past made it impossible to see. He threw the tracks into reverse, but the current sweeping them along was so strong that the digger was just barely in contact with the floor. He killed the floodlights because reflection from the froth outside the canopy was dazzling them. But there was still a patch of light ahead, growing steadily larger …

“Edwards, cut the rattlers …

A few seconds later they were swept out of the tunnel as part of a cataract which tumbled down an organic cliff into a ravine which seemed to have no bottom. The vehicle did not explode into its component parts nor themselves into strawberry jam, so they knew that Major Edwards had been able to kill the rattler batteries in time. When they crashed to a halt a subjective eternity later, two of the repeater screens died in spectacular implosions and the cataract which had cushioned their fall on the way down began battering at their side, pushing and rolling them along the floor of the incision.

“Anyone hurt?” said Conway.

Murchison eased her safety webbing and winced. “I’m black and blue and … and embossed all over.”

“That,” said Harrison in an obviously uninjured tone, “I would like to see.

Both relieved and irritated, Conway said, “First we should look at the patient.”

The only operable view screen was transmitting a picture taken from one of the copters stationed above the incision. The heavy cruisers had drawn off a short distance to leave the operative field clear for rescue and observation copters, which buzzed and dipped above the wound like great metal flies. Thousands of gallons of water were pouring from the severed throat tunnel every minute, carrying the bodies of leucocytes, farmer fish, incompletely digested food and clumps of vital internal vegetation into and along the ravine. Conway signaled for Edwards.

“We’re safe,” he said before the other could speak, “but this is a mess. Unless we can stop this loss of fluid, the stomach system will collapse and we will have killed instead of cured our patient. Dammit, why doesn’t it have some method of protecting itself against gross physical injury, a nonreturn valve arrangement or some such? I certainly did not expect this to happen …

Conway checked himself, realizing that he was beginning to whine and make excuses instead of issuing instructions. Briskly, he said, “I need expert advice. Have you a specialist in short-range, low-power explosive weapons?”

“Right,” said Edwards. A few seconds later a new voice said, “Ordnance control, Vespasian, Major Holroyd. Can I help you, Doctor?”

I sincerely hope so, thought Conway, while aloud he went onto outline his problem.

They were faced with the emergency situation of a patient bleeding to death on the table. Whether the being concerned was large or small, whether its body fluid was Earth-human blood, the superheated liquid metal used by the TLTUs of Threcald Five or the somewhat impure water which carried food and specialized internal organisms to the far flung extremities of this Drambon strata creature’s body, the result would be the same-steadily reducing blood pressure, increasingly deep shock, spreading muscular paralysis and death.

Normal procedure in these circumstances would be to control the bleeding by tying off the damaged blood vessel and suturing the wound. But this particular vessel was a tunnel with walls no more strong or elastic than the surrounding body material, so they could not be tied or even clamped. As Conway saw it the only method remaining was to plug the ruptured vessel by bringing down the tunnel roof.

“Close-range TR-7s,” said the ordnance officer quickly. “They are aerodynamically clean, so there will be no problem shooting into the flow, and provided there are no sharp bends near the mouth of the tunnel any desired penetration can be achieved by—”

“No,” said Conway firmly. “I’m concerned about the compression effects of a large explosion in the tunnel itself. The shock wave would be transmitted deep into the interior, and a great many farmer fish and leucocytes would die, not to mention large quantities of the fragile internal vegetation. We must seal the tunnel as close to the incision as possible, Major, and confine the damage to that area.

“Armor-piercing B-22s, then,” said Holroyd promptly. “In this material we could get penetrations of fifty yards without any trouble. I suggest a simultaneous launch of three missiles, spaced vertically above the tunnel mouth so that they will bring down enough loose material to block the tunnel even against the pressure of water trying to push it away as it subsides.”

“Now,” said Conway, “you’re talking.”

But Vespasian’s ordnance officer could do more than talk. Within a very few minutes the screen showed the cruiser hovering low over the incision. Conway did not see the missiles launched because he had suddenly remembered to check if their digger had been swept far enough to avoid being buried in the debris, which fortunately it had. His first indication that anything at all had happened was when the flow of water turned suddenly muddy, slowed to a trickle and stopped. A few minutes later great gobs of thick, viscous mud began to ooze over the lip of the tunnel and suddenly a wide area around the mouth began to sag, fall apart and slip like a mass of brown porridge into the ravine.

The tunnel mouth was now six times larger than it had been and the patient continued to bleed with undiminished force.

“Sorry, Doctor,” said Holroyd. “Shall I repeat the dose and try for greater penetration?”

“No, wait.”

Conway tried desperately to think. I knew that he was conducting a surgical operation, but he did not really believe it-both the problem and the patient were too big. If an Earth-human was in the same condition, even if no instruments or medication were available, he would know what to do-check the flow at a pressure point, apply a tourniquet … That was it.

“Holroyd, plant three more in the same position and depth as last time,” he said quickly. “But before you launch them can you arrange your vessel’s presser beams so that as many of them as possible will be focused just above the tunnel opening? Angle them against the face of the incision instead of having them acting vertically, if possible. The idea is to use the weight of your ship to compress and support the material brought down by the missiles.”

“Can do, Doctor.”

It took less than fifteen minutes for Vespasian to rearrange and refocus her invisible feet and launch the missiles, but almost at once the cataract ceased and this time it did not resume. The tunnel opening was gone and in its place there was a great, saucer-shaped depression in the wall of the incision where Vespasian’s starboard pressers were focused. Water still oozed through the compacted seal, but it would hold so long as the cruiser maintained position and leaned her not inconsiderable weight on it. As extra insurance another inflatable seal was already being moved into the supply tunnel.

Suddenly the picture was replaced by that of a lined, young-old face above green-clad shoulders on which there rested a quietly impressive weight of insignia. It was the Fleet Commander himself.

“Doctor Conway. My flagship has engaged in some odd exercises in her time, but never before have we been asked to hold a tourniquet.”

“I’m sorry, sir-it seemed the only way of handling the situation. But right now, if you don’t mind, I’d like you to have this digger lifted to map reference numbers …

He broke off because Harrison was waving at him. The Lieutenant said softly, “Not this digger. Ask him to have the other one checked out and waiting when they get around to pulling us out.”
