“ Neither are we unanimous on the basic matter as to why the Masters acted as they did just before they left Ardry. Why did they set the status so far below their top ability? Why did they make it impossible for the Omans ever, of themselves, to learn their higher science? Why, if they did not want that science to become known, did they leave complete records of it? The majority of us believe that the Masters coded their records in such fashion that the Stretts, even if they conquered the Omans or destroyed them, could never break that code ”

“ It can fail. All we actually know of the abilities of this postulated neo-human race is what I have learned from the composition of its defensive screen. The probability approaches unity that the Masters continued to delve and to learn for millions of cycles while you Stretts, reasonlessly certain of your supremacy, concentrated upon your evolution from the material to a non-material form of life and performed only limited research into armaments of greater and ever greater power. ”

“ There is an optimum mass, a point of maximum efficiency of firepower as balanced against loss of maneuverability, for any craft designed for attack,” Kedy thought, in his most professional manner. “We assume that the Stretts know that as well as we do. No such limitation applies to strictly defensive structures, but both the Strett craft and ours must be designed for attack. We have built and are building many hundreds of thousands of ships of that type. So, undoubtedly, are the Stretts. ”

“ Postulate that the Masters, in many thousands of cycles of study, made advances in science that were not reduced to practice; that the Omans either possessed this knowledge or had access to it; and that Omans and humans cooperated fully in sharing and in working with all the knowledges thus available. From these three postulates the conclusion can be drawn that there has come into existence a new race. ”

“ Finally, and most important, our physicists and theoreticians are not able to extrapolate, from the analysis of our screen, to the concepts underlying the Masters' ultimate weapons of offense, the first-stage booster and its final end-product, the Vang. If, as we can safely assume, the Stretts do not already have those weapons, they will know nothing about them until we ourselves use them in battle. ”

“ We will attack in maximum force and with maximum violence. We will blanket the planet. We will maintain maximum force and violence until most or all of the enemy ships have been destroyed. We will then install planetary drives on Ten and force it into collision orbit with Fuel World, meanwhile exerting extreme precautions that not so much as a spy-beam emerges above the enemy's screen. ”

“ You should increase the size and power of your warships to something beyond the computed probable maximum of the enemy. You should build more ships and missiles than they will probably be able to build. Then and only then will you attack their warships, in tremendous force and continuously.”
“But not their planetary defenses. ”

“ Hilton, however, accompanied Sawtelle and Kedy to the captain's office. “So you see, Skipper, we got troubles,” he said. “If we don't use those boosters against their skeletons it'll boil down to a stalemate lasting God only knows how long. It will be a war of attrition, outcome dependent on which side can build the most and biggest and strongest ships the fastest. On the other hand, if we do use 'em on defense here, they'll analyze 'em and have everything worked out in a day or so. The first thing they'll do is beef up their planetary defenses to match. ”

“ No mobile structure can be built to mount mechanisms of power sufficient to smash down by sheer force of output such tremendously powerful installations as their planet-based defenses must be assumed to be. ”

“ First, the world Ardry, upon which the Omans formerly lived and to which the humans in question first went—a planet which no Strett can peyondire—is now abandoned. Second, the Stretts of old did not completely destroy the humanity of the world Ardu. Third, some escapees from Ardu reached and populated the world Ardry. Fourth, the android Omans were developed on Ardry, by the human escapees from Ardu and their descendants. Fifth, the Omans referred to those humans as ‘Masters.’ Sixth, after living on Ardry for a very long period of time the Masters went elsewhere. ”
