It at length became apparent that we had missed the Dacia altogether. Such failures are not uncommon, and we were more pleased than disappointed, since our return to Wilhelmshaven was now in order. At noon June 28 we turned northeastward, and despite some rather comical entanglements with the unusual masses of dolphins, were soon under way.

The explosion in the engine room at 2 A .M. was wholly a surprise. No defect in the machinery or carelessness in the men had been noticed, yet without warning the ship was racked from end to end with a colossal shock. Lieutenant Kienze hurried to the engine room, finding the fuel-tank and most of the mechanism shattered, and Engineers Raabe and Schneider instantly killed. Our situation had suddenly become grave indeed; for though the chemical air regenerators were intact, and though we could use the devices for raising and submerging the ship and opening the hatches as long as compressed air and storage batteries might hold out, we were powerless to propel or guide the submarine. To seek rescue in the life-boats would be to deliver ourselves into the hands of enemies unreasonably embittered against our great German nation, and our wireless had failed ever since the Victory affair to put us in touch with a fellow U-boat of the Imperial Navy.

From the hour of the accident till July 2 we drifted constantly to the south, almost without plans and encountering no vessel. Dolphins still encircled the U– 29, a somewhat remarkable circumstance considering the distance we had covered. On the morning of July 2 we sighted a warship flying American colors, and the men became very restless in their desire to surrender. Finally Lieutenant Menze had to shoot a seaman named Traube, who urged this un-German act with especial violence. This quieted the crew for the time, and we submerged unseen.
