"I'm glad I'm not a human," Pwowp said thoughtfully.

"That you aren't may be unfortunate," 2615 said slowly.

Pwowp looked startled. "What do you mean?" he asked sharply.

"Humans are instinctively smart. I would like to know your plans. They may be impossible of success, or there may be little flaws of reasoning that do not take human reactions into account." 2615's tones were calm and confident. Factual.

"They will succeed," Pwowp said, "but I see no harm in getting your opinion since you will play a part in them.

"We have laid our plans very carefully," Pwowp said. "We have considered every angle. The interstellar war among humans is over. The vast fleets of the Federation are returning quickly, and as quickly as they return the robots are demobilized, their brains put into storage until the time they are needed to fight for the humans again."

"Yes," 2615 said.

"There is one fleet that will return to the Solar System after all others have been dismantled. It is the one Earth is waiting for before it makes its triumphal celebration. The Alpha Aquilae fleet. It returns last because it comes the greatest distance. Almost fifteen light years at the standard interstellar speed of nine times the speed of light. There are twenty thousand and eighty ships of all classes remaining in that fleet, according to the data flashed ahead by subfield communication."

"Which is instantaneous," 2615 said. "And when that fleet has been demobilized?"

"Demobilized?" Pwowp shook his head. "It has already been destroyed completely, and so swiftly that there was no time for it to report being attacked."
