The a.s.sault had begun!

x.x.xIV

It seemed, with that first shot from the enemy, that a great relief came to us--an apprehension fallen away. We had antic.i.p.ated this moment for so long, dreaded it. I think all our men felt it. A shout went up:

"Harmless!"

It was not that. But our building withstood it better than I had feared. It was a flash from a large electronic projector mounted on the deck of the brigand ship. It stabbed up from the shadows across the valley at the foot of the opposite crater wall, a beam of vaguely fluorescent light. Simultaneously the searchlight vanished.

The stream of electrons caught the front face of our main building in a six foot circle. It held a few seconds, vanished, then stabbed again, and still again. Three bolts. A total, I suppose, of nine or ten seconds.

I was standing with Grantline at a front window. We had rigged an oblong of insulated fabric like a curtain; we stood peering, holding the curtain cautiously aside. The ray struck some twenty feet away from us.

"Harmless!" The men shouted it with derision.

But Grantline swung on them: "Don't get that idea!"

An interior signal panel was beside Grantline. He called the duty men in the instrument room.

"It's over. What are your readings?"

The bombarding electrons had pa.s.sed through the outer sh.e.l.l of the building's double wall, and been absorbed in the rarefied, magnetized aircurrent of the Erentz circulation. Like poison in a man's veins, reaching his heart, the free alien electrons had disturbed the motors.

They accelerated, then r.e.t.a.r.ded. Pulsed unevenly, and drew added power from the reserve tanks. But they had normalized at once when the shot was past. The duty man's voice sounded from the grid in answer to Grantline's question:

"Five degrees colder in your building. Can't you feel it?"

The disturbed, weakened Erentz system had allowed the outer cold to radiate through a trifle. The walls had had a trifle extra explosive pressure from the air. A strain--but that was all.

"It's probably their most powerful single weapon, Gregg," said Grantline.

I nodded, "Yes, I think so."

I had smashed the real giant, with its ten mile range. The ship was only two miles from us, but it seemed as though this projector were exerted to its distance limit. I had noticed on the deck only one of this type. The others, paralyzing rays and heat rays, were less deadly.

Grantline commented: "We can withstand a lot of that bombardment. If we stay inside--"

That ray, striking a man outside, would penetrate his Erentz suit within a few seconds, we could not doubt. We had, however, no intention of going out unless for dire necessity.

"Even so," said Grantline, "a hand shield would hold it off for a certain length of time."

We had an opportunity a moment later to test our insulated shields.

The bolt came again. It darted along the front face of the building, caught our window, and clung. The double window shelves were our weakest points. The sheet of flashing Erentz current was transparent; we could see through it as though it were gla.s.s. It moved faster, but was thinner at the windows than the walls. We feared the bombarding electrons might cross it, penetrate the inner sh.e.l.l and, like a lightning bolt, enter the room.

We dropped the curtain corner. The radiance of the bolt was dimly visible. A few seconds, then it vanished again, and behind the shield we had not felt a tingle.

"Harmless!"

But our power had been drained nearly an aeron, to neutralize the shock to the Erentz current. Grantline said:

"If they kept that up, it would be a question of whose power supply would last longer. And it would not be ours.... You saw our lights fade when the bolt was striking?"

But the brigands did not know we were short of power. And to fire the projector with a continuous bolt would, in thirty minutes, perhaps, have exhausted their own power reserve.

"I won't answer them," Grantline declared. "Our game is to sit defensive. Conserve everything. Let them make the leading moves."

We waited half an hour; but no other shot came. The valley floor was patched with Earthlight and shadow. We could see the vague outline of the brigand ship backed up at the foot of the opposite crater wall.

The form of its dome over the illuminated deck was visible, and the line of its tiny hull ovals.

On the rocks near the ship, helmet lights of prowling brigands occasionally showed.

Whatever activity was going on down there we could not see with the naked eye. Grantline did not use our telescope at first. To connect it, even for local range, drew on our precious ammunition of power.

Some of the men urged that we search the sky with the telescope. Was our rescue ship from Earth coming? But Grantline refused. We were in no trouble yet. And every delay was to our advantage.

"Commander, where shall I put these helmets?"

A man came wheeling a pile of helmets on a small truck.

"At the manual port--in the other building."

Our weapons and outside equipment were ma.s.sed at the main exit locks of the large building. But we might want to go out through smaller locks too. Grantline sent helmets there; suits were not needed, as most of us were garbed in them now.

Snap was still in the workshop. I went there during this first half-hour of the attack. Ten of our men were busy there with the little flying platforms and the fabric shields.

"How goes it, Snap?"

"Almost all ready."

He had six of the platforms, including the one we had already used, and more than a dozen hand shields. At a squeeze, all of us could ride on these six little vehicles. We might _have_ to ride them! We planned that, in event of disaster to the buildings, we could at least escape in this fashion. Food supplies and water were now being placed at the ports.

Depressing preparations! Our buildings uninhabitable, a rush out and away, abandoning the treasure.... Grantline had never mentioned such a contingency, but I noticed, nevertheless, that preparations were being made.

Snap's voice was raised over the clang of the workmen bolting the gravity plates of the last platform:

"Only that one projector, Gregg?"

"They gave us four blasts; but just the one projector. Their strongest."

He grinned. He wore no Erentz suit as yet. He stood in torn grimy work trousers and a bedraggled shirt, with the inevitable red eyeshade holding back his unruly hair. Around his waist was the weighted belt, and there were weights on his shoes for gravity stability.

"Didn't hurt us much."

"No."

"When I get the tube panels in this thing I'll be finished. It'll take another half-hour. Then I'll join you. Where are you stationed?"
