"If they kept that up, it would be a question of whose power supply would last longest. And it would not be ours.... You saw our lights fade down while 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.

This strange warfare! It was new to all of us, for there had been no wars on any of the three inhabited worlds for many years. Silent, electronic conflict! Not a question of men in battle. A man at a switch on the brigand ship was the sole actor so far in this assault. And the results were visible only in the movement of the needle-dials on our instrument panels. A struggle, so far, not of man's bravery, or skill, or strategy, but merely of electronic power supply.


et warfare, however modern, can never transcend the human element. Before this insult was ended I was to have many demonstrations of that!

"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 illumined 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.
