* * * * * Then a gun on the Wabbly moved. It spouted a flash of bluish flame, and then another and another. It seemed to fire gas-shells into the town, at this moment, ignoring the batteries playing upon it. It was still again, while the queer excrescence on its back moved vaguely and shells burst about it in a very inferno. Then the treads moved, and with a swift celerity the Wabbly moved smoothly forward and up the incline toward the cannonading guns. It went over the top of the incline, and those in the gyrocar saw its reception. Guns opened on it at point-blank range. Now the Wabbly itself went into action. In the light of star-shells and explosions they saw its guns begin to bellow. It went swiftly and malevolently forward, moving with centipedean smoothness. It dipped out of sight. The cannonade lessened. Two guns stopped. Three.... Half a dozen guns were out of action. A dozen guns ceased to fire.... One last weapon boomed desperately at its maximum rate of fire.... That stopped. The night became strangely, terribly still. The major-general put aside his radivision receiver. Though neither the helicopter pilot nor Sergeant Walpole had noticed it, he had opened communication the instant the gyrocar came to a stop. Now the major-general was desperately, terribly white. "The artillery is wiped out," he observed detachedly. "The Wabbly, it seems, is going on into the town." They did not want to listen, those men who waited futilely by the gyrocar which had witnessed the invulnerability of the Wabbly to all attack. They did not want to listen at all. But they heard the noises as the Wabbly crashed across the town, and back and forth. "Morale effect," said the major-general, through stiff lips. "That's what it's for. To break down the morale behind the lines. Good God! What hellish things mere words can mean!" PART V
