The fog—that all-pervading East Frisian fog—which had been thickening steadily during the inspection, settled down in a solid bank while we sat at lunch. With a scant dozen yards of visibility, the Commander rated the prospects of crossing to the mainland so unfavourable that he suggested our remaining for the night at one of the Norderney hotels still open, and going over to Borkum (which we were planning to reach by destroyer) the next morning by launch. It was the difficulty in securing a prompt confirmation of what would have been a time-saving change of schedule which led Captain H—— to reject the plan and decide in favour of making an attempt to reach Norddeich in, and in spite of, the fog. The Commander shook his head dubiously. "My men who know the passage best have left the station," he said; "but I will do the best I can for you, and perhaps you will have luck." He saw us off at the landing with the same quiet courtesy with which he had received us. He was a very likable chap, that Commander; perhaps the one individual with whom we were thrown into intimate contact in the course of the whole visit to whom one would have thought of applying that term.
Noticing that the launch in which we were backing away from the landing was at least double the size of the one in which we had crossed, I asked one of the German officers if the greater draught of it was not likely to increase our chances of running aground.
"Of course," he replied; "but the larger cabin will also be much more comfortable if we have to wait for the next tide to get off."
As the launch swung slowly round in the mud-and-sand stained welter of reversed screws, I bethought me of the "Riddle" again, and fished it forth from my pocket. It was disappointing to leave without having had a glimpse of the town where "Dollmann" and his "rose-brown-cheeked" daughter Clara had lived, but the fog closed us round in a grey-walled cylinder scarcely more in diameter than the launch was long. But we were right on the course, I reflected, of the dinghy which "Davies" piloted with such consummate skill through just such a fog ("five yards or so was the radius of our vision," wrote "Carruthers") to Memmert to spy on the conference at the salvage plant on that desolate sand-spit. I turned up the chapter headed "Blindfold to Memmert," and read how, sounding with a notched boathook in the shallows that masterly young sailor had felt his way across the Buse Tief to the eastern outlet of the Memmert Balje, the only channel deep enough to carry the dinghy through the half-bared sandbanks between Juist and the mainland. Our own problem, it seemed to me, was a very similar one to that which confronted "Davies," only, in our case, it was the entrance of the channel where the Buse Tief narrowed between the Hohes Riff and the Itzendorf Plate that had to be located. Failing that, we were destined to roost till the next tide on a sandbank, and that meant we were out for all night, as there would be no chance of keeping to a channel, however well marked, in both fog and darkness.
Ten minutes went by—fifteen—twenty—with no sign of the buoy which marked the opening we were trying to strike. Now the engines were eased down to quarter-speed, and she lost way just in time to back off from a shining glacis of steel-grey sand that came creeping out of the fog. For the next ten minutes, with bare steerage way on, she nosed cautiously this way and that, like a man groping for a doorway in the dark. Then a hail from the lookout on the bow was echoed by exclamations of relief from the German officers. "Here is the outer buoy," one of them called across to us reassuringly; "the rest of the way is well marked and easy to follow. We will soon be at Norddeich."
Presently a fresh buoy appeared as we nosed on shoreward, then a second, and then a third, continuing the line of the first two. Speed was increased to "half," and the intervals of picking up the marks correspondingly cut down. Confident that there was nothing more to worry about, I pulled out "The Riddle" again, for I had just recalled that it was about halfway to Norddeich, in the Buse Tief, that "Carruthers" had brought off his crowning exploit, the running aground of the tug and "invasion" lighter—with Von Brunning, Boehme, and the mysterious "cloaked passenger"—as they neared the end of the successful night trial trip in the North Sea. Substituting himself for the man at the wheel by a ruse, he had edged the tug over to starboard and was just thinking "What the Dickens'll happen to her?" when the end came; "a euthanasia so mild and gradual (for the sands are fringed with mud) that the disaster was on us before I was aware of it. There was just the tiniest premonitory shuddering as our keel clove the buttery medium, a cascade of ripples from either beam, and the wheel jammed to rigidity in my hands as the tug nestled up to her final resting-place."
And very like that it was with us. It was a guttural oath from somewhere forward rather than any perceptible jar that told me the launch had struck, and it was not till after the screw had been churning sand for half a minute that there was any perceptible heel. It had come about through one of the buoys being missing and the next in line out of place, one of the Germans reckoned; but whatever the cause, there we were—stuck fast. Or, at least, we would have been with any less resourceful and energetic a crew. If their very lives had depended on it, those four or five German seamen could not have worked harder, nor to better purpose, to get that launch free. At the end of a quarter of an hour their indefatigable efforts were rewarded, and a half hour later we were settling ourselves in the warm compartment of our waiting train. The Hun has no proper sense of humour. Reverse the rôles, and any British bluejackets I have ever known would have run a German Armistice Commission on to the first sandbank that hove in sight, and damned the consequences.
