By hanging in the infra band, on the ragged edge of threespace, a scout ship could remain concealed until a critical moment, breakout into threespace--discharge her weapons--and flick back into Cth before an enemy could get a fix on her. Scouts, with their high capacity converters, could perform this maneuver, but the ponderous battlewagons and cruisers with their tremendous weight of armor, screens, and munitions couldn't maneuver like this. They simply didn't have the agility. Yet only they had the ability to penetrate defensive screens and kill the Rebel heavies. So space battle was conducted on the classic pattern--the Lines slugging it out at medium range while the screen of scouts buzzed around and through the battle trying to add their weight of metal against some overstrained enemy and ensure his destruction. A major battle could go on for days--and it often did. In the Fifty Suns action the battle had lasted nearly two weeks subjective before we withdrew to lick our wounds. * * * * * For nearly a day we ran into nothing, and such are the distances that separate units of a fleet, we had the impression that we were alone. We moved quietly, detectors out, scanning the area for a light-day around as we moved forward at less than one Lume through Cth. More would have been fatal for had we been forced to resort to a quick breakout to avoid enemy action, and if we were travelling above one Lume when we hit threespace, we'd simply disappear, leaving a small spatial vortex in our wake. On the "morning" of the third day the ships at the apex of Quadrant One ran into a flight of Rebel scouts. There was a brief flurry of action, the Rebels were englobed, a couple of cruisers drove in, latched onto the helplessly straining Rebel scouts and dragged them into threespace. The Rebs kept broadcasting right up to the end--after which they surrendered before the cruisers could annihilate them. Smart boys. But the Rebels were warned. We couldn't catch all their scouts and the disturbance our Line was making in Cth would register on any detector within twenty parsecs. So they would be waiting to meet us. But that was to be expected. There is no such thing as surprise in a major action.
