His black, white-nosed mocker was standing in the open doorway and watching the hurrying men and prowlers with worried interest: Tip, the great-great-great-great grandson of the mocker that had died with Howard Lake north of the plateau. He reached down to pick him up and set him on his shoulder, and said:

"Jim?"

"The longbows are ready," Tip's treble imitation of Jim Chiara's voice answered. "We'll black out their searchlights when the time comes."

"Andy?" he asked.

"The last of us for this section are coming in now," Andy Taylor answered.

He made his check of all the subleaders, then looked up to the roof to ask, "All set, Jimmy?"

Jimmy Stevens' grinning face appeared over the edge. "Ten crossbows are cocked and waiting up here. Bring us our targets."

They waited, while the evening deepened into near-dusk. Then the airlock of the cruiser slid open and thirteen Gerns emerged, the one leading them wearing the resplendent uniform of a subcommander.

"There they come," he said to Lake and Craig. "It looks like we'll be able to trap them in here and force the commander to send out a full-sized force. We'll all attack at the sound of the horn and if you can hit their rear flanks hard enough with the unicorns to give us a chance to split them from this end some of us should make it to the ship before they realize up in the control room that they should close the airlocks.

"Now"—he looked at the Gerns who were coming straight toward the stockade wall, ignoring the gate to their right—"you'd better be on your way. We'll meet again before long in the ship."
