Turning about and breasting the waves we faced the oncoming steamer and signaled to her to stop; but hardly had she espied us than she also turned about in the hope to escape. She showed no flag to indicate her nationality, so surely we had sighted an English vessel. Even after we had fired a warning shot, she tried by rapid and tortuous curves to return to her former course, and endeavor thereby to reach her home port. Meantime she sent up rockets as signals of distress in quick succession to draw the attention of British patrol ships that must be hovering in the neighborhood.

This obliged us to fire a decisive shot, and with a loud report our first shell struck the ship close to the captain’s bridge. Instead of resigning himself to his fate, the Englishman sent up more signals and hoisted the British flag. This showed us he was game, and the fight began in dead earnest. All honor to the pluck of these English captains—but how reckless to expose in this manner the lives of their passengers and crew, as we shall see in the present instance. . . .

The fight had lasted four hours without our being able to deliver the death stroke. Several fires had started on the steamer, but the crew had been able to keep them under control; big holes gaped open in the ship’s side, but there were none as yet below the water line, and the pumps still sufficed to expel the water. . . .

It was now essential for us to put an end to this deadly combat, for English torpedo-boat destroyers were hurrying on to the calls of distress of the steamer. Big clouds of smoke against the sky showed they were coming towards us under full steam. The ship was by this time listing so heavily that it was evident we need waste no more of our ammunition. . . . We cast a last look on our courageous adversary who was gradually sinking, and I must add it was the first and last prey whose end we did not have the satisfaction to witness. We had been truly impressed by the captain’s brave endurance, notwithstanding his lack of wisdom, and we knew that the men-of-war were coming to his rescue. We read in the papers, on our return to a German port, that the “Vosges” had sunk soon after we had departed, and what remained of the passengers and crew were picked up by the English ships. The captain was rewarded for his temerity by being raised to the rank of Reserve officer, and the crew were given sums of money; but all the other officers had perished, as well as several sailors and a few passengers, who had been forced to help the stokers in order to increase the speed of the flying steamer.
