It soon became evident that the Boskonians could not maneuver their forces efficiently. Their fleet was too huge, too unwieldy for their operations officers to handle. Against an equally uncontrollable mob of battle craft it would have made a showing, but against the carefully planned, chronometer-timed attack of the Patrol individual action, however courageous or however desperate, was useless. Each red-sheathed destroyer hurtled along a definite course at a definite force of drive for a definite length of time. Orders were strict; no ship was to be lured from course, pace, or time. They could, however, fight en passant with their every weapon if occasion arose; and occasion did arise, some thousands of times. The units of Grand Fleet flashed inward, lashing out with their terrible primaries at everything in space not wearing the crimson robe of civilization. And whatever those beams struck did not need striking again. The warships of Boskone fought back. Many of the Patrol's defensive screens blazed hot enough almost to mask the scarlet beacons; some of them went down. A few Patrol ships were englobed by the concerted action of two or three subfleet commanders more co-operative or more farsighted than the rest, and were blasted out of existence by an overwhelming concentration of power. But even those vessels took toll with their primaries as they went out; few, indeed, were the Boskonians who escaped through holes thus made. At a predetermined instant each dreadnought stopped, to find herself one nut of an immense, red-flaming hollow sphere of ships packed almost screen to screen. And upon signal every primary projector that could be brought to bear hurled bolt after bolt, as fast as the burned-out shells could be replaced, into the ragingly incandescent inferno which that sphere's interior instantly became. For two hundred million discharges such as those will convert even a very large volume of space into something utterly impossible to describe. The raving torrents of energy subsided and keen-eyed observers swept the scene of action. Nothing was there except jumbled and tumbling white-hot wreckage. A few vessels had escaped during the closing in of the sphere, but none inside it had survived this climactic action--not one in five thousand of Boskone's massed fleet made its way back to dark Jarnevon. "Maneuver fifty-eight--hipe!" and Grand Fleet shot away. There was no waiting, no hesitation. Every course and time had been calculated and assigned.
