Inside the solid Earth there was a deep grumbling as of some immense giant complaining and turning in his sleep, a sound so great it shook the solid stone above and transmitted itself to the water which in turn struck the solid steel fabric of the submarines, jarring them and tossing them about before passing on.
“Earthquake…” Gus said, rising from the deck where he had been thrown. “An undersea quake, just now…”
He stopped, aghast at what was happening outside, the scene so clearly displayed on the screen. The tremors in the Earth had been passed to the anchored cables which were bending and writhing like things alive, sending traveling shock waves along their length to the lightly anchored bridge above. The bridge and anchoring cables had been designed to absorb shocks and quakes like these, but as a unit, well secured and soundly anchored. Now the two cables were bearing all the strain that twenty had been designed for. It was impossible; it was happening. What damage was being wrought to the bridge! Gus dared not stop to consider, the damage before his eyes was even greater for, harshly burdened and overstrained, the cables were tearing from their fittings.
Terrible to see, impossible to turn away from, the heavy steel and concrete anchors crumbling and shattering, breaking free. Pulling from the moment’s paralysis Gus grabbed for the communicator.
“Number Two, draw or release your cable, do you hear me?”
“I can attach, I can—”
The words cut off, never finished as tragedy struck. With the two holding cables torn loose the floating bridge above twisted and moved, bent, floating free, dragging on the attached cables. The submarine, Number Two that was about to attach its cable, was simply lashed forward like a child’s toy at the end of a string and thrown against the stony wall. It took a fraction of an instant, no more, as the pressure hull cracked and the incredible weight of the water at this depth compressed, destroyed, flattened the vessel in the smallest part of a second, so quickly that her crew must have had no slightest warning of their doom. It fell slowly, a dead weight at the end of the cable.
Gus could spend no time with concern for the dead now, for he must think of the living, the submarines still attached to the bridge and the fate of the bridge itself. For long seconds he forced himself to stand there, to think logically, to consider every factor before going into action, while all of the time the communicator roared with voices, questions, cries of anguish. Reaching a decision he smashed down the command switch and spoke with cold clarity into the microphone.
“Clear all communication circuits, silence, absolute silence, this is Washington speaking and I want silence.” And he received it for within seconds the last voice died away and as soon as it had he spoke again. “Come in Section Two commander, give a report. We have had a quake at this end and are not co

It was a desperate maneuver, a plan conceived in a few moments in an attempt to master this unforeseen situation, a complicated stratagem that had to be enacted faultlessly in the midnight deeps where every man and every sub was separate and alone, yet interdependent. In his mind’s eye Gus could see the bridge and he went over what must be done again in detail and was convinced that he was attempting the only thing possible.
The floating bridge was secured to its pier at one end only, the opposite end on the eastern cliff. With the west end unattached the current would push against the structure, bending it down-current to the south, bending it more and more until it broke and water flooded the air-filled tu
The first thing he had to do was detach all the odd numbered subs which, like his own vehicle, had been towing the bridge from the southern, down-current, side. If any attempt was made to pull on the bridge with these cable moorings from the up-current side, they would twist the bridge as though trying to wind it up and this would destroy it as quickly as the current. If all was going correctly the odd numbered subs would have released their cables by now and would be fleeing up over the bridge; Nautilus II was below the freed cables so she could swing up-current and rise to join the subs that remained attached to their mooring cables. These would be fighting to keep the bridge from bending, pulling in a northerly direction with the full power of their engines. Pray they would succeed!
As the Nautilus II churned upwards they saw a horrifying sight on their screens, the view from their topside pickup. The row of lights on the bridge was no longer a straight line, but had curved instead into a monstrous letter C where the free end was being swept south by the current. Gus took one look then immediately snapped on the command circuit.
“To all subs that have dropped their cables: Rejoin others above who are attempting to hold the position of the west end of the bridge, use your magnetic grapples to secure to these subs then use full reverse power as well. We must stop the bridge from bending, we must straighten it.”
Nautilus II led the way, nuzzling up beside one of the straining subs, touching her, then being held fast as the powerful electromagnet on the hull seized tight to the other. As soon as they were attached the engines whined, louder and louder, as they sped up to full reverse revolutions. If this helped it was not immediately visible for the bridge bent and bent even more until the free end was pointing almost due south. The designers had allowed for flexibility, but certainly not for this much, it would surely break at any moment.
Yet it did not. One by one the other subs latched on to their mates and added their power to the total effort. They could not straighten out the frightening bend but it appeared they had it checked at last. They were not gaining, but at least they had stopped losing. They needed more power.
“Attention all units of Section Two. Continue attaching cables your end. We are barely holding here. As each unit secures its cable proceed at maximum speed to this end and grapple to another sub. We need your help.”
It came. One after another the other submarines swam up out of the darkness and ran their hulls against the subs already there until they clustered together like grapes, two, three and four in a group, straining at the cables. At first there seemed to be no result, try as hard as they could, then—Was it happening? Was the curve shallower? It was almost impossible to tell. Gus rubbed at his eyes as O’Toole spoke.
“Sure and I’m not the one to be making empty claims, but it’s my feeling that we’re moving astern just the smallest amount.” No sooner were the words from his mouth than the communicator buzzed.
“Anemone here. I am in position near the cliff face and have been observing. Southern motion stopped. We appear now to be moving north at a very slow, but steady, pace.”
