Even before those heat-bombs struck, our onrushing ships had curved like lightning upward again, but the next moment were reeling and tossing even in the mad upward rush as from beneath came a titanic merged flare of all the bursting heat-bombs, from which an awful wave of super-heated air rushed up and overtook us, and beneath whose terrific released heat dozens of the huge military buildings beneath had fused and melted. We could glimpse, too, that below a full half thousand or more of the resting cruisers had perished also in that giant flare, and that it was as though a whole great area of the gigantic air-city beneath us had been transformed suddenly by the released heat of our mighty bombs into a huge crater of white-hot, melting metal near the floating city's edge! And from all across the mighty white-lit mass of Berlin, that had reeled itself in mid-air from that terrific blow, there rose a dull, roaring clamor of millions of voices that came up to us even over the drone of our great motors and the rush of winds about us! Upward at utmost speed we were rushing, and just in time for hardly had our heat-bombs struck when, despite the utter unexpectedness of our attack, the great batteries of heat-guns around the central electrostatic tower that guarded it were wheeling toward us and thundering as they shot a storm of heat-shells above the white-lit city toward us. Even as I had said, those vigilant watchers at the power-tower would have blasted our fleet from the air before we could have ever got near to the tower itself, but as it was we had struck a terrific blow at the military arsenals and the resting fleet, and had flashed upward again in time to escape the blasting guns at the city's center. But now, through the night above the vast roaring city, the batteries all around its rim were swinging their pivoted guns toward us and sending a hail of shells after us while, as all the city's great searchlights wheeled their beams madly through the air toward us, the swarming patrols all around us had recovered from their stunned astonishment and were leaping also toward us! "One more attack!" over the uproar I was yelling into our distance-phone as we shot upward through that mad chaos of whirling beams and ships and shells. "The city's western arsenals this time--loose the other half of our bombs on them!"
