As I glance to-day through my notes of those first days in the Atlantic, I continually come across remarks of this kind: "Heavy Sea," "Stiff wind from the W.N.W., Strength 8," "Wind blowing up for a storm," "Heavy seas rolling over the whole boat and even over the conning-tower," "Boat travelling almost continuously under water," etc. In these few curt sentences lies the history of the hard and nerve-racking existence of twenty-nine men, shut up in the body of a steel fish, as she made her way untiringly through the wild tossing seas. I know of no better opportunity of praising the excellently thought-out construction and the perfect seafaring qualities of our "Deutschland" than in calling to mind those stormy days in the Atlantic. The elements certainly did not help to make our journey to America an easy one. The highest possible demands were made on the body and machinery of the boat, which had to be continually at work day after day in order that we might reach our destination. And here I cannot help thinking with gratitude of the dockyard and all the men whose work had contributed to help us complete our journey by giving this wonderful piece of sea-craft mechanism into our hands. It is easy to wax enthusiastic over a fine ship, that delights the eye of every onlooker when in harbour by her elegance, and extracts the admiration of the expert and the uninitiated by her rapid movement in smooth waters. But the real inner worth of a ship is only to be discovered when she has completed her test on the high seas. Then, and only then, you learn her best qualities and gain that real confidence in her trustworthiness and seafaring capabilities, when the wind is blowing with a strength 10, and the sea has a roughness 8, during which you must go head on. And this not only for a couple of hours, but day after day, week after week. Only then can a ship prove what she is really worth. This is particularly the case with a U-Boat in war time. A merchantman in peace time has very often a severe strain in holding out, but she has always the possibility of seeking a port of refuge, or of hailing assistance. At the worst, she can drift a few days and wait for smoother weather. None of this is possible with the U-Boat. To the dangers of the sea are added the dangers from the enemy, the cruellest and most pitiless of enemies. No haven of refuge beckons to her, and if she were to lie for a few minutes helpless and be discovered, her adversaries, who would have helped a damaged steamer in distress, would loosen the greedy bloodhounds at her throat. No one is so lonely and entirely dependent on himself as a U-Boat captain. If he cannot absolutely rely on his vessel, then he is lost.
