"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 I heard nothing. 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; my head roared with it. Spots danced before my closed eyes. Then not enough oxygen. I was dully smothering....

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

"Anita! Anita, dear!"

"Yes. Gregg. All right."

The melee went on. The brigand ship and all its vicinity was enveloped in darkness-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 search-light 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 did not mean that--I didn't see it."

Almost a collision.

"Oh, 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 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.

We swooped. But not too low! Down in the darkness-mist we would immediately have lost direction, and crashed.

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 occasionally 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 our explosions, enveloped the enemy. Our camp search-light 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 there 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! Dear G.o.d....

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.

And now I saw why probably we had never yet hit the ship.

Its outline was revealed. "Now, Gregg--can you fling it from here?"

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 would have 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."

"Yes."

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

I was suddenly shocked with horror. The search-ray from our camp abruptly 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 thoughts 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 of his men to attack our almost abandoned 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 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 small 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.

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

I might be able to open its manual hull-lock, rip it open and let the air out. If I could get into its pressure chamber and unseal the inner slide....

"It would wreck the ship, Anita, exhaust all its air. Shall we try it?"

"Whatever you say, Gregg."
