Astounding Stories of Super-Science, August 1930

"Norman!" he babbled. "In God's name--Fellows--!" "That helmet, Hackett!" Fellows flung at him. "My God, look at those prisoners--Norman!" The countless thousands of green men released from the buildings whose walls had vanished under the shells of the invaders had poured forth to make the amphibian city a chaos of madness. Oblivious to all else they were throwing themselves upon the city's crowding frog-men in a battle whose ferocity was beyond belief, disregarding all else in this supreme chance to wreak vengeance on the monstrous beings who had fed upon their blood. In the incredible insanity of that raging fury the craft of the green men hanging over the city were all but forgotten. Suddenly the city and the mighty dome over it quivered violently, and then again. There came from beneath a dull, vast, grinding roar. "The great force-bombs!" Fellows screamed. "They've set them off--the city's sinking--out of here, for the love of God!" The boat whirled beneath Sarja's hands toward the pool of the water-tunnel, all their fleet rushing with them. The grinding roar was louder, terrible; dome and city were shaking violently now; but in the insensate fury of their struggle the frog-men and their released prisoners were hardly aware of it. The whole great dome seemed sinking upon them and the city falling beneath it as Sarja's craft ripped down into the tunnel's waters, and then out, at awful speed, as the great tunnel's walls swayed and sank around them! They shot out into the green depths from it to hear a dull, colossal crashing through the waters from behind as the great pedestal of rock on which the city had stood, shattered by the huge force-bombs, collapsed. And as their boats flashed up into the open air they saw that the huge dome of the city of the Ralas was gone.
