Our three exclamations came together in that moment, exclamations that must have been echoed then from every watcher in our onrushing ships. Berlin! In all its stupendous, radiant splendor it hung before and beneath us, the mighty air-city that was the European Federation's capital and center, equalled in size only by New York and Peking. There between earth and stars it floated, its white-lit towers soaring up from the mighty metal base, all out-topped by the slender central pinnacle that was the great city's electrostatic tower which drew from earth's charge its electric power. Around the city's edge there stabbed and circled the giant white beams of its great searchlights, sweeping to and fro over the still-thronged streets, in which we knew there surged the crowding masses of the great air-city's population. And high above these, moving restlessly to and fro, there came and went the great network of patrols which guarded the great metropolis of the air on all sides. But our own ships, winging more slowly on at our tremendous height, were never glimpsed by the patrols so far beneath us, never caught at our great height by the great white beams that came and went below, and that only occasionally clove the night above. And as my order brought our ships to a halt, we could make out more details in the white-lit city floating far beneath us. Could make out, as we hung there motionless, the great batteries of pivoted heat-guns set at the central plaza and all around the city's encircling wall, the great square metal buildings of the arsenals, in two groups at the city's east and western edges, the central headquarters and arsenals of all the European Federation's military forces. On the plazas around those buildings rested long ranks of gleaming cruisers, cruisers that numbered thousands and, we knew, were those with whom we had battled so furiously over and in the Atlantic a day before. And it was down toward these buildings and these cruisers that we gazed now, in that moment before the city's cruiser-finders beneath could detect us and spread the alarm. "The cruisers and military buildings and arsenals below will be our main objective," I said into the distance-phone as we hung there in that tense moment, above the shining city. "The city's electrostatic tower is so closely defended by heat-gun batteries that we could never get near it, and like all power-towers of air-cities it's of metal alloys that the heat of our shells and bombs wouldn't affect, so we can't hope to destroy it and thus crash the city to earth by cutting off its sustaining flow of power. Our goal must be the cruisers and arsenals, and we'll attack them in two great swoops, the eastern ones first and then the western, and if all goes well can then swiftly escape before the forces below can gather and rise against us!" A Sudden Attack
