Now Memmert was part of the outer rampart; its tapering sickle of sand directly commanded the eastern breach; it must be connected with the defence of this breach. No more admirable base could be imagined; self-contained and isolated, yet sheltered, accessible—better than Juist and Borkum. And supposing it were desired to shroud the nature of the work in absolute secrecy, what a pretext lay to hand in the wreck and its buried bullion, which lay in the offing opposite the fairway!
On Memmert was the depôt for the salvage operations. Salvage work, with its dredging and diving, offered precisely the disguise that was needed. It was submarine, and so are some of the most important defences of ports, mines, and dirigible torpedoes. All the details of the story were suggestive: the “small local company”; the “engineer from Bremen” (who, I wondered, was he?); the few shares held by von Brüning, enough to explain his visits; the stores and gear coming from Wilhelmshaven, a naval dockyard.
Try as I would I could not stir Davies’s imagination as mine was stirred. He was bent on only seeing the objections, which, of course, were numerous enough. Could secrecy be ensured under pretext of salving a wreck? It must be a secret shared by many—divers, crews of tugs, employees of all sorts. I answered that trade secrets are often preserved under no less difficult conditions, and why not imperial secrets?
“Why the Ems and not the Elbe?” he asked.
“Perhaps,” I replied, “the Elbe, too, holds similar mysteries.” Neuerk Island might, for all we knew, be another Memmert; when cruising in that region we had had no eyes for such things, absorbed in a preconceived theory of our own. Besides, we must not take ourselves too seriously. We were amateurs, not experts in coast defence, and on such vague grounds to fastidiously reject a clue which went so far as this one was to quarrel with our luck. There was a disheartening corollary to this latter argument that in my new-born zeal I shut my eyes to. As amateurs, were we capable of using our clue and gaining exact knowledge of the defences in question? Davies, I knew, felt this strongly, and I think it accounted for his lukewarm view of Memmert more than he was aware. He clung more obstinately than ever to his “channel theory”, conscious that it offered the one sort of opportunity of which with his peculiar gifts he was able to take advantage. He admitted, however, that it was under a cloud at present, for if knowledge of the coastwise navigation were a crime in itself we should scarcely be sitting here now. “It’s something to do with it, anyhow!” he persisted.
CHAPTER XVIII.
Imperial Escort
Memmert gripped me, then, to the exclusion of a rival notion which had given me no little perplexity during the conversation with von Brüning. His reiterated advice that we should lose no time in picking up our anchor and chain had ended by giving me the idea that he was anxious to get us away from Bensersiel and the mainland. At first I had taken the advice partly as a test of our veracity (as I gave the reader to understand), and partly as an indirect method of lulling any suspicions which Grimm’s midnight visit may have caused. Then it struck me that this might be over-subtlety on my part, and the idea recurred when the question of our future plans cropped up, and hampered me in deciding on a course. It returned again when von Brüning offered to tow us out in the evening. It was in my mind when I questioned him as to his business ashore, for it occurred to me that perhaps his landing here was not solely due to a wish to inspect the crew of the Dulcibella. Then came his perfectly frank explanation (with its sinister double entente for us), coupled with an invitation to me to accompany him to Esens. But, on the principle of timeo Danaos etc., I instantly smelt a ruse, not that I dreamt that I was to be decoyed into captivity; but if there was anything here which we two might discover in the few hours left to us, it was an ingenious plan to remove the most observant of the two till the hour of departure.
Davies scorned them, and I had felt only a faint curiosity in these insignificant hamlets, influenced, I am afraid, chiefly by a hankering after terra firma which the pitiless rigour of his training had been unable to cure.
But it was imprudent to neglect the slightest chance. It was three o’clock, and I think both our brains were beginning to be addled with thinking in close confinement. I suggested that we should finish our council of war in the open, and we both donned oilskins and turned out. The sky had hardened and banked into an even canopy of lead, and the wind drove before it a fine cold rain. You could hear the murmur of the rising flood on the sands outside, but the harbour was high above it still, and the Dulcibella and the other boats squatted low in a bed of black slime. Native interest seemed to be at last assuaged, for not a soul was visible on the bank (I cannot call it a quay); but the top of a black sou’wester with a feather of smoke curling round it showed above the forehatch of the Kormoran.
“I wish I could get a look at your cargo, my friend,” I thought to myself.
