“Almost on target, sir,” called the tech on the tracking screen.

Krogson stalked menacingly toward Kurt. “Get away from those controls!” he snarled. “You aren’t going to blow anything to anything. All that you can do is let off a premature blast. If you are trying to alert your base, it’s no use. We can be on a return sweep before they have time to get ready for us.”

Kurt shook his head calmly. “Wouldn’t do you any good,” he said. “Take a look at the gun ports on the other ships. I made a couple of minor changes while I was working on the control bank.”

“Quit bluffing,” said Krogson.

“I’m not bluffing,” said Kurt quietly. “Take a look. It won’t cost you anything.”

“On target!” called the tracking tech.

“Order the fleet to circle for another sweep,” snapped Krogson over his shoulder as he stalked toward the forward observation port. There was something in Kurt’s tone that had impressed him more than he liked to admit. He squinted out toward the nearest ship. Suddenly his face blanched!

“The gunports! They’re closed!”

Kurt gave a whistle of relief. “I had my fingers crossed,” he said pleasantly. “You didn’t give me enough time with the wiring diagrams for me to be sure that cutting out that circuit would do the trick. Now… guess what the results would be if I should happen to push down on this stud.”

Krogson had a momentary vision of several hundred shells ramming their sensitive noses against the thick chrome steel of the closed gun ports.
