"Space attack!" Colonel Zareff was indignant. "There never was a time when the Alliance could have taken the offensive against Poictesme, even if an offensive outside our own space-area had been part of our policy. We just didn't have the ships. It took over a year to move a million and a half troops from Ashmodai to Marduk, and the fleet that was based on Amaterasu was blasted out of existence in the spaceports and in orbit. Hell, at the time of the surrender, we didn't have--" "They weren't taking chances on that, Colonel. But the point I want to make is that with everything I did find, I never found, in any official record, a single word about the giant computer we call the Third Fleet-Army Force Brain." For a time, the only sound in the room was the tiny insectile humming of the electric clock on the wall. Then Professor Kellton set his glass on the table, and it sounded like a hammer-blow. "Nothing, Conn?" Kurt Fawzi was incredulous and, for the first time, frightened. The others were exchanging uneasy glances. "But you must have! A thing like that--" "Of course it would be one of the closest secrets during the war," somebody else said. "But in forty years, you'd expect _something_ to leak out." "Why, _during_ the war, it was all through the Third Force. Even the Alliance knew about it; that's how Klem heard of it." "Well, Conn couldn't just walk into the secret files and read whatever he wanted to. Just because he couldn't find anything--" "Don't tell _me_ about security!" Klem Zareff snorted. "Certainly they still have it classified; staff-brass'd rather lose an eye than declassify anything. If you'd seen the lengths our staff went to--hell, we lost battles because the staff wouldn't release information the troops in the field needed. I remember once--" "But there _was_ a Brain," Judge Ledue was saying, to reassure himself and draw agreement from the others. "It was capable of combining data, and scanning and evaluating all its positronic memories, and forming association patterns, and reasoning with absolute perfection. It was more than a positronic brain--it was a positronic super-mind." "We'd have won the war, except for the Brain. We had ninety systems, a hundred and thirty inhabited planets, a hundred billion people--and we were on the defensive in our own space-area! Every move we made was known and anticipated by the Federation. How could they have done that without something like the Brain?" "Conn, from what you learned of computers, how large a volume of space would you say the Brain would have to occupy?" Professor Kellton asked. Professor Kellton was the most unworldly of the lot, yet he was asking the most practical question.
