With every man in both fleets dead the warships raged through emptiness, pouring out destruction from their unmanned projectors. It was a hundred years before the last war-craft, its fuel gone and its crew mere dust, was captured and destroyed. But there had been no space-fight since--until now. And this one was strangeness itself. Four huge, squat ships of war rose steadily from the planet Sinab Two. They were doubtless bound on a mission of massacre. The Empire of Sinab gave no warning of its purpose. It did not permit the option of submission. Its ships headed heavily out into space, crammed with generators of the murder-frequency. They had no inkling of any ships other than those of their own empire as being in existence anywhere. Suddenly, out of nowhere, a slim and slender space-craft winked into being--a member of Kim's squadron, just arrived. Within a fraction of an instant it was plunging furiously for the Sinabian monster. The _Starshine_ also flung itself into head-long attack, though it was unarmed save for projectors of a field that would not kill anyone. The other ships--and more, as they appeared--darted valorously for the giants. Meteor-repellers lashed out automatically. Scanners had detected the newcomers and instantly flung repeller-beams to thrust them aside. They had no effect. Meteor-repellers handle inert mass but, by the nature of its action, an interplanetary drive neutralizes their effect. The small ships flashed on. Kim found himself grinning sardonically. There would be alarms ringing frantically in the enemy ships and the officers would be paralyzed with astonishment at the sudden appearance and instant attack by the space-craft which could not--to Sinabian knowledge--exist. Four ships plunged upon one monster. Three dashed at another. Eight little motes streaked for a third and the fourth seemed surrounded by deadly mites of space-ships, flashing toward it with every indication of vengeful resolution. The attacks were sudden, unexpected, and impossible. There was no time to put the murder-beams into operation. They took priceless seconds to warm up. In stark panic the control-room officer of the ship at which the _Starshine_ drove jammed his ship into overdrive travel. The Sinabian flashed into flight at two hundred times the speed of light. It fled into untraceable retreat, stressed space folded about it. Kim spoke comfortably into the space-phone: "Everything's fine! If the others do the same...." A second giant fled in the same fashion. The small ships of Ades were appearing on every hand and plunging toward their enemies. A third huge ship made a crazy, irresolute half-turn and also took the only possible course by darting away from its home planet on overdrive. Then the fourth! "They'd no time to give an alarm," said Kim crisply. "Into atmosphere now and we do our stuff!"
