The appearance of the lieutenant commander and much-decorated U-boat captain in the auditorium of our school put an end to the concerts from within the former Polish mine sweeper Rybitwa. Even if he had not turned up, the records and the phonograph couldn't have held out for more than another three or four days. But he did turn up, and without having to pay a visit to our barge he turned off the underwater music and gave all our conversations about Mahlke a new, though not fundamentally new, turn.

The lieutenant commander must have graduated in about '34. It was said that before volunteering for the Navy he had studied some at the university: theology and German literature. I can't help it, I am obliged to call his eyes fiery. His hair was thick and kinky, maybe wiry would be the word, and there was something of the old Roman about his head. No submariner's beard, but aggressive eyebrows that suggested an overhanging roof. His forehead was that of a philosopher-saint, hence no horizontal wrinkles, but two vertical lines, beginning at the bridge of the nose and rising in search of God. The light played on the uppermost point of the bold vault. Nose small and sharp. The mouth he opened for us was a delicately curved orator's mouth. The auditorium was overcrowded with people and morning sun. We were forced to huddle in the window niches. Whose idea had it been to invite the two upper classes of the Gudrun School? The girls occupied the front rows of benches; they should have worn brassieres, but didn't.

When the proctor called us to the lecture, Mahlke hadn't wanted to attend. Flairing some possible gain in prestige for myself, I took him by the sleeve. Beside me, in the window niche – behind us the windowpanes and the motionless chestnut trees in the recreation yard – Mahlke began to tremble before the lieutenant commander had even opened his mouth. Mahlke's hands clutched Mahlke's knees, but the trembling continued. The teachers, including two lady teachers from the Gudrun School, occupied a semicircle of oak chairs with high backs and leather cushions, which the proctor had set up with remarkable precision. Dr. Moeller clapped his hands, and little by little the audience quieted down for Dr. Klohse, our principal. Behind the twin braids and pony tails of the upper-class girls sat Fourths with pocketknives; braids were quickly shifted from back to front. Only the pony tails remained within reach of the Fourths and their knives. This time there was an introduction. Klohse spoke of all those who are out there fighting for us, on land, on the sea, and in the air, spoke at length and with little inflection of himself and the students at Langemarck, and on the Isle of Osel fell Walter Flex. Quotation: Maturebutpure – the manly virtues. Then some Fichte or Arndt. Quotation: Onyou-aloneandwhatyoudo. Recollection of an excellent paper on Fichte or Arndt that the lieutenant commander had written in Second: "One of us, from our midst, a product of our school and its spirit, and in this spirit let us…"

Need I say how zealously notes were passed back and forth between us in the window niches and the girls from Upper Second. Of course the Fourths mixed in a few obscenities of their own. I wrote a note saying Godknowswhat either to Vera Plötz or to Hildchen Matull, but got no answer from either. Mahlke's hands were still clutching Mahlke's knees. The trembling died down. The lieutenant commander on the platform sat slightly crushed between old Dr. Brunies, who as usual was calmly sucking hard candy, and Dr. Stachnitz, our Latin teacher. As the introduction droned to an end, as our notes passed back and forth, as the Fourths with pocket-knives, as the eyes of the Führer's photograph met those of the oil-painted Baron von Conradi, as the morning sun slipped out of the auditorium, the lieutenant commander moistened his delicately curved orator's mouth and stared morosely at the audience, making a heroic effort to exclude the girl students from his field of vision. Cap perched with dignity on his parallel knees. Under the cap his gloves. Dress uniform. The hardware on his neck plainly discernible against an inconceivably white shirt. Sudden movement of his head, half followed by his decoration, toward the lateral windows: Mahlke trembled, feeling no doubt that he had been recognized, but he hadn't. Through the window in whose niche we huddled the U-boat captain gazed at dusty, motionless chestnut trees; what, I thought then or think now, what can he be thinking, what can Mahlke be thinking, or Klohse while speaking, or Brumes while sucking, or Vera Plötz while your note, or Hildchen Matull, what can he he he be thinking, Mahlke or the fellow with the orator's mouth? For it would have been illuminating to know what a U-boat captain thinks while obliged to listen, while his gaze roams free without cross-wires and dancing horizon, until Joachim Mahlke feels singled out; but actually he was staring over schoolboys' heads, through double windowpanes, at the dry greenness of the poker-faced trees in the recreation yard, giving his orator's mouth one last moistening with his bright-red tongue, for Klohse was trying, with words on peppermint breath, to send a last sentence out past the middle of the auditorium: "And today it beseems us in the homeland to give our full attention to what you sons of our nation have to report from the front, from every front."

The orator's mouth had deceived us. The lieutenant commander started out with a very colorless survey such as one might have found in any naval manual: the function of the submarine. German submarines in the First World War: Weddigen and the U9, submarine plays decisive role in Dardanelles campaign, sinking a total of thirteen million gross register tons. Our first 250-ton subs, electric when submerged, diesel on the surface, the name of Prien was dropped, Prien and the U47, and Lieutenant Commander Prien sent the Royal Oak to the bottom – hell, we knew all that – as well as the Repulse, and Schuhart sank the Courageous, and so on and so on. And then all the old saws: "The crew is a body of men who have sworn to stand together in life and death, for far from home, terrible nervous strain, you can imagine, living in a sardine can in the middle of the Atlantic or the Arctic, cramped humid hot, men obliged to sleep on spare torpedoes, nothing stirring for days on end, empty horizon, then suddenly a convoy, heavily guarded, everything has to go like clockwork, not an unnecessary syllable; when we bagged our first tanker, the Amdale, 17,200 tons, with two fish amidships, believe it or not, I thought of you, my dear Dr. Stachnitz, and began to recite out loud, without turning off the intercom, qui quae quod, cuius cuius cuius… until our exec called back: Good work, skipper, you may take the rest of the day off. But a submarine mission isn't all shooting and tube one fire and tube two fire; for days on end it's the same monotonous sea, the rolling and pounding of the boat, and overhead the sky, a sky to make your head reel, I tell you, and sunsets…"

Although the lieutenant commander with the hardware on his neck had sunk 250,000 gross register tons, a light cruiser of the Despatch class and a heavy destroyer of the Tribal class, the details of his exploits took up much less space in his talk than verbose descriptions of nature. No metaphor was too daring. For instance: "…swaying like a train of priceless, dazzlingly white lace, the foaming wake follows the boat which, swathed like a bride in festive veils of spray, strides onward to the marriage of death."

The tittering wasn't limited to the pigtail contingent; but in the ensuing metaphor the bride was obliterated: "A submarine is like a whale with a hump, but what of its bow wave? It is like the twirling, many times twirled mustache of a hussar."

The lieutenant commander also had a way of intoning dry technical terms as if they had been dark words of legend. Probably his lecture was addressed more to Papa Brunies, his former German teacher, known as a lover of Eichendorff, than to us. Klohse had mentioned the eloquence of his school themes, and perhaps he wished to show that his tongue had lost none of its cunning. Such words as "bilge pump" and "helmsman" were uttered in a mysterious whisper. He must have thought he was offering us a revelation when he said "master compass" or "repeater compass." Good Lord, we had known all this stuff for years. He saw himself as the kindly grandmother telling fairy tales. The voice in which he spoke of a dog-watch or a watertight door or even something as commonplace as a "choppy cross sea"! It was like listening to dear old Andersen or the Brothers Grimm telling a spooky tale about "sonar impulses."

When he started brushing in sunsets, it got really embarrassing: "And before the Atlantic night descends on us like a flock of ravens transformed by enchantment into a black shroud, the sky takes on colors we never see at home. An orange flares up, fleshy and unnatural, then airy and weightless, bejeweled at the edges as in the paintings of old masters; and in between, feathery clouds; and oh what a strange light over the rolling full-blooded sea!"

Standing there with his sugar candy on his neck, he sounded the color organ, rising to a roar, descending to a whisper, from watery blue to cold-glazed lemon yellow to brownish purple. Poppies blazed in the sky, and in their midst clouds, first silver, then suffused with red: "So must it be," these were his actual words, "when birds and angels bleed to death." And suddenly from out of this sky, so daringly described, from out of bucolic little clouds, he conjured up a seaplane of the Sunderland type. It came buzzing toward his U-boat but accomplished nothing. Then with the same orator's mouth but without metaphors, he opened the second part of his lecture. Chopped, dry, matter-of-fact: "I'm sitting in the periscope seat. Just scored a hit. Probably a refrigerator ship. Sinks stern first. We take the boat down at one one zero. Destroyer comes in on one seven zero. We come left ten degrees. New course: one two zero, steady on one two zero. Propeller sounds fade, increase, come in at one eight zero, ash cans: six… seven… eight… eleven: lights go out; pitch-darkness, then the emergency lighting comes on, and one after another the stations report all clear. Destroyer has stopped. Last bearing one six zero, we come left ten degrees. New course four five…"

Unfortunately, this really exciting fillet was followed by more prose poems: "The Atlantic winter" or "Phosphorescence in the Mediterranean," and a genre painting: "Christmas on a submarine," with the inevitable broom transformed into a Christmas tree. In conclusion he rose to mythical heights: the homecoming after a successful mission, Ulysses, and at long last: "The first sea gulls tell us that the port is near."
