I held my bomb out over the shield, calculating the angle to throw it down. The brigand rays flashed around me. They were horribly close; Miko had understood our sudden visible shift and aimed, not where we appeared to be, but approximately where we had been before.

I dropped my bomb hastily at the glowing white ship. The touch of a hostile ray would have exploded it in my hand. I saw others dropping also from our nearby platforms. The explosions from them merged in a confusion of the white glare--and a cloud of black mist as the brigands out on the rocks used their darkness bombs.

We swept past in a blur of leaping hostile beams. Silent battle of lights! Darkness bombs down at the ship struggling to bar our camp searchray. The Benson radiance rays from our pa.s.sing platforms, curving down to mingle with the confusion. The electronic rays sending up their bolts....

Our platforms dropped some ten dynamitrine bombs in that first pa.s.sage over the ship. As we sped by, I dimmed the Benson radiance. I peered.

We had not hit the ship. Or if we had, the damage was inconclusive.

But on the rocks I could see a pile of ore carts scattered--broken wreckage, in which the litter of two or three projectors seemed strewn. And the gruesome deflated forms of several helmeted figures.

Others seemed to be running, scattering--hiding in the rocks and pit-holes. Twenty brigands at least were outside the ship. Some were running over toward the base of our camp ledge. The darkness bombs were spreading like a curtain over the valley floor; but it seemed that some of the figures were dragging their projectors away.

We sailed off toward the opposite crater rim. I remember pa.s.sing over the broken wreckage of Grantline's little s.p.a.ceship, the _Comet_.

Miko's bolts momentarily had vanished. We had hit some of his outside projectors; the others were abandoned, or being dragged to safer positions.

After a mile we wheeled and went back. I suddenly realized that only four platforms were in the re-formed line ahead of us. One was missing! I saw it now, wavering down, close over the ship. A bolt leaped up diagonally from a distant angle on the rocks and caught the disabled platform. It fell, whirling, glowing red--disappeared into the blur of darkness like a bit of heated metal plunged into water.

One out of six of our platforms already lost! Three men of our small force gone!

But Grantline led us desperately back. Anita caught his signal to break our line. The five platforms scattered, dipping and wheeling like frightened birds--blurring shapes, shifting unnaturally in flight as the Benson curve lights were altered.

Anita now took our platform in a long swoop downward. Her tense, murmured voice sounded in my ears:

"Hold off; I'll take us low."

A melee. Pa.s.sing platform shapes. The darting bolts, crossing like ancient rapiers. Falling blue points of fuse lights as we threw our bombs.

Down in a swoop. Then rising. Away, and then back. This silent warfare of lights! It seemed that around me must be bursting a pandemonium of sound. Yet there was none. Silent, blurred melee, infinitely frightening. A bolt struck us, clung for an instant; but we weathered it. The light was blinding. Through my gloves I could feel the tingle of the over charged shield as it caught and absorbed the hostile bombardment. Under me the platform seemed heated. My little Erentz motors ran with ragged pulse. I got too much oxygen. I was dully smothering....

Then the bolt was gone. I found us soaring upward, horribly tilted. I shifted over.

"Anita! Anita, dear, are you all right?"

"Yes, Gregg. All right."

The melee went on. The brigand ship and all its vicinity were enveloped in dark mist now--a turgid sable curtain, made more dense by the dissipating heavy fumes of our exploding bombs which settled low over the ship and the rocks nearby. The searchlight from our camp strove futilely to penetrate the cloud.

Our platforms were separated. One went by, high over us. I saw another dart close beneath my shield.

"G.o.d, Anita!"

"Too close! I didn't see it."

Almost a collision.

"Gregg, haven't we broken the ship's dome yet?"

It seemed not. I had dropped nearly all my bombs. This could not go on much longer. Had it been only about five minutes? Only that? Reason told me so, yet it seemed an eternity of horror.

Another swoop. My last bomb. Anita had brought us into position to fling it. But I could not. A bolt stabbed up from the gloom and caught us. We huddled, pulling the shields up and over us.

Blurred darkness again. Too much to the side now. I had to wait while Anita swung us back. Then we seemed too high.

I waited with my last bomb. The other platforms were occasionally dropping them: I had been too hasty, too prodigal.

Had we broken the ship's dome with a direct hit? It seemed not.

The brigands were sending up catapulted light flares. They came from positions on the rocks outside the ship. They mounted in lazy curves and burst over us. The concealing darkness, broken only by the flares of explosions, enveloped the enemy. Our camp searchlight was still struggling with it. But overhead, where the few little platforms were circling and swooping, the flares gave an almost continuous glare. It was dazzling, blinding. Even through the smoked pane which I adjusted to my visor I could not stand it.

But these were thoughts of comparative dimness. In a patch where the Earthlight struck through the darkness of the rocks, I saw another of our fallen platforms! Snap and Venza?

It was not they, but three figures of our men. One was dead. Two had survived the fall. They stood up, staggering. And in that instant, before the turgid black curtain closed over them, I saw two brigands come rushing. Their hand projectors stabbed at close range. Our men crumpled and fell....

We were in position again. I flung my last missile, watched its light as it dropped. On the dome roof two of Miko's men were crouching. My bomb was truly aimed--perhaps one of the few in all our bombardment which landed directly on the dome roof. But the waiting marksmen fired at it with short range heat projectors and exploded it harmlessly while it was still above them.

We swung up and away. I saw, high above us, Grantline's platform, recognizing its red signal light. There seemed a lull. The enemy fire had died down to only a very occasional bolt. In the confusion of my whirling impressions, I wondered if Miko were in distress. Not that!

We had not hit his ship; perhaps we had done little damage indeed! It was we who were in distress. Two of our platforms had fallen--two out of six. Or more, of which I did not know.

I saw one rising off to the side of us. Grantline was over us. Well, we were at least three. And then I saw the fourth.

"Grantline is calling us up, Gregg."

Grantline's signal light was summoning us from the attack. He was a thousand feet or more above us.

I was suddenly shocked with horror. The searchray from our camp suddenly vanished! Anita wheeled us to face the distant ledge. The camp lights showed, and over one of the buildings was a distress light!

Had the crack in our front wall broken, threatening explosion of all the buildings? The wild thought swept me. But it was not that. I could see light stabs from the cliff outside the main building. Miko had dared to send some men to attack our almost deserted camp!

Grantline realized it. His red helmet light semaph.o.r.ed the command to follow him. His platform soared away, heading for the camp, with the other two behind him.

Anita lifted us to follow. But I checked her.

"No! Off to the right, across the valley."

"But Gregg!"

"Do as I say, Anita."

She swung us diagonally away from both the camp and the brigand ship.

I prayed that we might not be noticed by the brigands.

"Anita, listen: I've got an idea!"

The attack on the brigand ship was over. It lay enveloped in the darkness of the powder gas cloud and its own darkness bombs. But it was uninjured.

Miko had answered us with our own tactics. He had practically unmanned the ship, no doubt, and had sent his men to our buildings. The fight had shifted. But I was now without ammunition, save for two or three bullet projectors.

Of what use for our platform to rush back? Miko expected that. His attack on the camp was undoubtedly made just for that purpose: to lure us back there.

"Anita, if we can get down on the rocks somewhere near the ship, and creep up un.o.bserved in that blackness...."
