title="[35]"/> the same second a decision must be made, and the commands carried out. A moment’s hesitation may be fatal.

I can give an example of this on the very morning I speak of.

It was three minutes after six o’clock, and within about half an hour the sun would rise, but the sea and the sky still floated together in the colorless drab of early dawn and permitted one only to imagine, not see, that partition wall, the horizon.

Unceasingly our binoculars pierced the gray dusk of daybreak. Suddenly a shiver went through my body when—only a second immovable and in intense suspense—a dark shadow within range of the spy-glass made me jump. The shadow grew and became larger, like a giant on the horizon—one mast; one, two, three, four funnels—a destroyer.

A quick command—I leap down into the tower. The water rushes into the diving tanks. The conning tower covers slam tight behind me—and the agony which follows tries our patience, while we count seconds with watches in hand until the tanks are filled, and the boat slips below the sea.

Never in my life did a second seem so long to me. The destroyer, which is not more than two thousand meters distant from us, has, of course, seen us, and is speeding for us as fast as her forty thousand horse power can drive her. From the guns mounted on her bow flash one shot after another aimed to destroy us.

Good God! If he only does not hit! Just one little hit, and we are lost! Already the water splashes on the outside of the conning tower up to the glass windows through which I see the dark ghost, streaking straight for us. It is terrifying to hear the shells bursting all around us in the water. It sounds like a triphammer against a steel plate, and closer and closer come the metallic crashes. The rascal is getting our range.

There—the fifth shot—the entire boat trembles—then the deceitful daylight disappears from the conning tower window. The boat obeys the diving rudder and submerges into the sea.

A reddish-yellow light shines all around us; the indicator of the manometer, which measures our depth, points to eight meters, nine meters, ten meters, twelve meters. Saved!

What a happy, unexplainable sensation to know that you are hiding deep in the infinite ocean! The heart, which had stopped beating during these long seconds because it had no time to beat, again begins its pounding.

Our boat sinks deeper and deeper. It obeys, as does a faithful horse the slightest pressure of a rider’s knees, which, in this case, are the diving rudders placed in the bow and the stern. The manometer now shows twenty-four meters, twenty-six meters. I had given orders we should go down to thirty meters.

Above us we still hear the roaring and crackling in the water, as if it were in an impotent rage. I turn and smile at the mate who is standing with me in the conning tower—a happy, care-free smile. I point upwards with my thumb.

“Do you hear it? Do you hear it?”

It is an unnecessary question, of course, because he hears it as plainly as I do, and all the others aboard hear it, too. But the question can still be explained because of the tremendous strain on our nerves which has to express itself even in such a simple question.

Dear, true, splendid little boat, how one learns to love you during such trying moments and would like to pet you like a living human being for your understanding and obedience! We, here on board, all depend upon you, just as we all depend upon one another. We are chained together. We will face the dangers together and gain success.

You blond heroes who are standing down there in the bowels of the boat without knowing what is happening up in the light, but still knowing that the crucial moment has arrived—that life or death to every one depends on one man’s will and one man’s decision; you who, with a calm and strong feeling of duty, stick at your posts with all the strength of your bodies and souls strained to the breaking point and still keep full faith in him who is your leader, chief, and commander; you show the highest degree of bravery and self-control, you who never have a chance to see the enemy but still, with sustained calm, do your duty.

Not a word was uttered, not a sound disturbed that deadly stillness on board. One almost forgot that the men were standing with strained nerves at their posts in order to keep the wonderful mechanism running right. One could hear the soft whirr of the dynamos and, more and more distant, the crackling of the exploding shells. Suddenly even this stopped. The Britisher must have noticed that the fish had slipped out of his hand. Shortly thereafter we heard his propellers churning the water above us. Soon this noise died away as it had come, growing fainter and fainter in a kind of grinding whirr.

“Did you hear how he circled around over us?” I asked through the speaking tube which led down into the “Centrale.”

“Certainly. That could clearly be distinguished,” was the short answer.

I was pondering over what to do next. At first we had no choice but to dive at the first sight of the destroyer suddenly appearing with the break of day.

In our capacity as an undersea boat, we were now in a position to fight on equal terms, and I decided to risk a bout with him as soon as it became light enough for me to see through the periscope. The intervening time I made use of by having passed up to me in the tower the long desired cup of morning coffee, in order to stop the tantalizing agony which the smell of the coffee had caused my empty stomach. Thereupon we slowly climbed upwards from our safe breakfast depth of thirty meters. The higher we came—one can read on the manometer how we are ascending meter by meter—the greater became the excitement and tension. Without breathing we listened.

Slowly the boat rose. The top of the periscope would soon be thrust above the surface. My hands clasped the handle with which the well-oiled, and therefore easily movable, periscope can be turned around as quickly as lightning, in order to take a sweep around the horizon. My eye was pressed to the sight, and soon I perceived that the water was getting clearer and clearer by degrees and more transparent. I could now follow the ascent of the boat without consulting the manometer.

My heart was pounding with the huntsman’s fervor, in expectation of what I was to see at my first quick glance around the horizon, because the destroyer, which we sighted only a quarter of an hour before, could be only a scouting ship. It might belong to a detachment of naval scouts to protect a larger ship. In my thoughts I saw the whole eastern horizon full of proud ships under England’s flag surrounded by smoke.

I did not see anything, no matter how carefully I scanned the horizon. All I could see was the reddening morning blush spread over half of the eastern sky, the last stars now paling and the rising sun showing its first beams.

“For heaven’s sake, nobody is here,” I grumbled to myself.

“Oh, he’ll surely come back, Captain,” said my mate with true optimism. “The prey was too hot for him to tackle and now he has started to fetch a couple more to help him.”

“It would certainly be less desirable,” put in Lieutenant Gröning, who, full of expectations, was standing halfway up the stairway leading from the tower to the “Centrale” and had overheard our talk. “No, it would be less desirable,” he repeated, “because then comes the entire swarm
