“Quite so. I’m all in favour of suitable aeroplanes,” Selwyn admitted. “We must upset this Zeppelin menace by some means or other. Here we are—the greatest and most powerful nation the world has ever seen, worried three times a month by the threat of these German gas-bags! It is quite possible to obtain such aeroplanes as would enable us to fight the Zepps. As somebody wrote in the paper the other day regarding the future range of the naval big guns, it is useless to send up half-trained quirks on soggy seaplanes accompanied by still less trained spotting officers equipped with short-range wireless which cannot receive. The gun-spotter in a Fleet action should be a fully trained and experienced gunnery-Jack, seated in a comfortable observation-car where charts and navigating instruments can be used with accuracy. Therefore, if we can’t get the proper aeroplanes, we must have airships for the purpose, as they are at present the only apparent vehicle for scientific gunnery in a Fleet action.”

With this we all agreed.

“Another point,” I said, “was advanced by a clever writer in the Aeroplane the other day. It was pointed out that in the matter of fighting Zeppelins, however good aeroplane patrols may be, they must depend on their eyes to find enemy airships. One may silence engines, but one cannot silence air, and, though one may shut off and glide slowly, yet there will always be enough whistling of wind round wires and struts to wash out any noise of airship engines, gears, and propellers, unless they are very close indeed. An airship, on the other hand, can shut off and float. There may be some creaking of the girders, and stays, but there will be no continuous whistling. Therefore an airship makes a perfect listening-post for enemy aircraft of all kinds.”

“I’m quite sure of that,” declared Charlie Digby from the depths of his chair. “If we are to win the war we must fight the Zeppelin. We want a real good man at the head of affairs and we should allow him a free hand, and put a stop to the endless committees and conferences and confabulations which have been the curse of this country in every department since war began—and before. Let that man have the advice of all the specialists he may require, and let him encourage people with ideas to offer their advice, instead of turning them down, as is the custom of most people in commanding positions.”

Those same sentiments I had read in one of the papers that very day.

I said nothing more. It was time for me to be off, so I rose and left, having an appointment with Teddy Ashton.

As I passed through the big hall of the club I reflected how true were Digby’s words. If we were to win the war we must fight the Zeppelins effectively.

But how?

That same question had occupied the minds of both Teddy and myself for many months, long indeed before the first Zeppelin had crossed the North Sea. Both of us had realised the deadly peril of those huge murder-machines against which we would be utterly powerless.

During the first year of war the public had laughed at the idea of Zeppelins coming over to drop bombs on undefended towns, or making an air raid upon London. The popular reply to anyone who ventured to express fear of such a thing as had been openly threatened in the German Press was: “Bah! they haven’t come yet!”
