Second Stage Lensmen by E.E. Smith

In the meantime the more warlike forces of the _Dauntless_ had not been idle. In the instant of the opening of the cavern's doors Captain Craig erupted orders, and as soon as the Lyranian was out of the line of fire, keen-eyed needle-ray men saw to it that those doors were in no mechanical condition to close. The _Dauntless_ settled downward; landed in front of the entrance to the cavern. The rocky, broken terrain meant nothing to her; the hardest, jaggedest boulders crumbled instantly to dust as her enormous mass drove the file-hard, inflexible armor of her midzone deep into the ground.

Worsel was fairly shivering with eagerness for the fray. His was, and with plenty of reason, the bitterest by far of all the animosities there present against the Overlords. For Delgon and his own native planet, Velantia, were neighboring worlds, circling about the same sun. Since the beginning of Velantian space flights, the Overlords of Delgon had preyed upon the Velantians; in fact, the Overlords had probably caused the first Velantian spaceship to be built. They had called them, in a never-ending stream, across the empty gulf of space. They had pinned them against their torture screens, had flayed them and had tweaked them to bits, had done them to death in every one of the numberless slow and hideous fashions which had been developed by a race of sadists who had been specializing in the fine art of torture for thousands upon thousands of years.
