"And I am glad to see you," he returned quietly, "though I would rather it were under more fortunate circumstances. But the battle is over and with your permission, we will not refer to it again." "Agreed," replied Lord Hastings, and led the way to his cabin, motioning for Captain von Mueller, Frank and Jack to follow. He introduced the lads to the great German commander, and the latter expressed his pleasure at seeing them. At this moment the third officer entered and spoke to Lord Hastings. "Launch from the Sydney coming alongside, sir," he said. "Show Captain Glossop here when he comes aboard," he said. The third officer withdrew. He appeared again a moment later, however, followed by the commander of the Sydney. Introductions followed. "Captain von Mueller," said Lord Hastings at length, "it will be necessary for me to turn you over to Captain Glossop. You will go with him aboard the Sydney. Were I returning direct to England, it would give me pleasure to have you accompany me. However, the Sydney will go straight back to Melbourne, and you will be taken there and held as a prisoner of war." Captain von Mueller signified his understanding of the situation. He expressed pleasure at having met Lord Hastings again, and that the fortunes of war had made him the prisoner of such gallant Englishmen. After some further talk, Captain von Mueller and Captain Glossop disappeared over the side of the Sylph, and put off toward the Sydney. Before either vessel proceeded on its way, several further messages were exchanged between the commanders of the Sydney and the Sylph; but at length the Sydney began to draw away toward the east. "And so," said Lord Hastings to the two lads, as they stood leaning over the rail, after the Sylph was once more under way, "so goes the 'German Terror of the Sea.'" The Sylph now turned her head once more to the west, and started on her journey back toward the Mediterranean. She steamed along slowly, Lord Hastings, greatly satisfied with the success of his mission, being in no particular hurry. They put in at Ceylon for coal; then once more resumed their journey. It was the second day after leaving Ceylon that the lookout made a startling discovery. "Submarine off the starboard bow, sir!" he called. Instantly there was excitement on board the Sylph, for there was no telling whether the submarine were friend or foe. At length those on the bridge were able to make out the periscope of the vessel, close to the water. And at this very moment it stood higher and higher in the water. The submarine was coming to the surface. The Sylph had been quickly stripped for action, for Lord Hastings had determined to give battle should the submarine prove to be an enemy. All available guns were turned upon the spot where the submarine was rising. But hardly had the under-sea craft come to the surface than a British ensign was run up. Lord Hastings breathed easier.
