In the early evening we rose to the surface, and found the sea less heavy. The smoke of a battleship was on the northern horizon, but our distance and ability to submerge made us safe. What worried us more was the talk of Boatswain Muller, which grew wilder as night came on. He was in a detestably childish state, and babbled of some illusion of dead bodies drifting past the undersea portholes; bodies which looked at him intensely, and which he recognized in spite of bloating as having seen dying during some of our victorious German exploits. And he said that the young man we had found and tossed overboard was their leader. This was very gruesome and abnormal, so we confined Muller in irons and had him soundly whipped. The men were not pleased at his punishment, but discipline was necessary. We also denied the request of a delegation headed by Seaman Zimmer, that the curious carved ivory head be cast into the sea.

On June 20, Seaman Bohin and Schmidt, who had been ill the day before, became violently insane. I regretted that no physician was included in our complement of officers, since German lives are precious; but the constant ravings of the two concerning a terrible curse were most subversive of discipline, so drastic steps were taken. The crew accepted the event in a sullen fashion, but it seemed to quiet Muller; who thereafter gave us no trouble. In the evening we released him, and he went about his duties silently.

In the week that followed we were all very nervous, watching for the Dacia . The tension was aggravated by the disappearance of Muller and Zimmer, who undoubtedly committed suicide as a result of the fears which had seemed to harass them, though they were not observed in the act of jumping overboard. I was rather glad to be rid of Muller, for even his silence had unfavorably affected the crew. Everyone seemed inclined to be silent now, as though holding a secret fear. Many were ill, but none made a disturbance. Lieutenant Kienze chafed under the strain, and was annoyed by the merest trifle – such as the school of dolphins which gathered about the U– 29 in increasing numbers, and the growing intensity of that southward current which was not on our chart.
