"I know," Roysland admitted; "but we have prisoners; members of the enemy's armed forces. We can get our information from them."
Allerdyce was still shaking his head. "How? They've been treated mentally against probing. They won't tell us where their home planets are, any more than our own men would—or could—tell them."
Roysland, in turn, shook his head. "That's not what I'm looking for. I'm not a military man; I'm a scientist—at least I think I am. I'm not looking for military bases; I'm looking for a planet where the Enlissa have planted their flora and fauna. That's what we do with a planet, isn't it? Seed it long before we colonize. If they've done as much colonization as we have—and their war potential shows that they must have—then they'll have a lot of planets that aren't inhabited by the Enlissa themselves, but will have been seeded by Enlissa-type life.
"At least one of the crewmen from that ship will know where such a planet is located. And I'm willing to bet that he won't be conditioned against telling us."
"Why not?" Allerdyce asked.
"For the same reason you haven't thought of it," Roysland said, grinning. "The Colonization Service and the Fleet Command are two different branches. Unless the aliens think differently than we do, their organization is about the same. And every bit of evidence shows that their reasoning is similar.
"There's no reason to protect an unpopulated planet, is there? Besides, the military don't inspect colonization records. Why should they? And what would it matter if the enemy took over an unpopulated planet? After all, we have as much chance of taking over one of theirs."
Allerdyce thought it over before answering. Finally, he said: "I'll check with Bilford. If he thinks we can get that much information out of an alien, I'll O.K. the trip. I'll have to insist, of course, that the X-69 be fully armed and subject to military orders."
"Naturally," Roysland agreed. "Just let me make the trip; that's all."
"I'll see what I can do," said Allerdyce. "Meanwhile, I'm going to call Colonization Service."
