A couple of thousand feet overhead, a silvery-grey, bluff-pointed cylinder was moving with apparent slowness. Half a dozen search-lights concentrated their beams upon it. All around were rings of smoke, marking the bursting shells from the anti-aircraft guns; yet, apparently untouched by the hail of bullets, the giant gas-bag passed on, hurling out death and destruction upon the greatest city on earth—a city that, until the present war, had only once heard the thunder of hostile guns.
Breathlessly the lads watched the progress of the huge Zeppelin, momentarily expecting it to collapse and come tumbling, a tangled mass of flaming wreckage, to the ground. Viewed from below, it seemed impossible for the airship to escape the bursting shells. The air was rent by the crash of falling bombs and the sharp reports of the "anti's", while in the distance could be heard the clatter of broken glass. The explosive bombs wrought havoc upon the homes of harmless Londoners. Flames, too, were springing up, throwing a lurid glare upon the sky.
Yet, unless actually within radius of the German explosives, the populace was remarkably calm. Men, women, and children watched the Zeppelin, much in the same way as if they were witnessing a Brock's display at the Crystal Palace. Once again German frightfulness had failed—and failed badly—to attain its desired end.
"Hurrah! She's got it properly in the neck," shouted an excited special constable, as the Zeppelin gave a sudden lurch and began to drop at an acute angle.
But the next instant the silvery envelope was hidden in a cloud of dense black smoke. Seconds passed, but no shattered wreckage streamed earthwards. When the vapour dispersed, the Zeppelin was nowhere to be seen. Under cover of the smoke-cloud she had dropped a large quantity of ballast, and had soared skyward to a great altitude.
Gradually, like the rumble of a passing thunderstorm, the reports of the distant anti-aircraft guns died away. The Zepps had taken themselves off, leaving half a dozen fires and hundreds of more or less damaged buildings to impress upon the strafed English that insularity is no longer a protection from the cowardly night-raiders of the air.
"The show's over," declared Ross. "I vote we turn in. By Jove, there'll be a rush to the recruiting offices to-morrow!"
Requesting to be called at eight, the two midshipmen entered the lift and were whisked up to their room.
"What's that noise?" asked Vernon, pausing in the midst of unpacking his portmanteau.
"Something in the corridor," replied Ross.
