which the sudden explosion had temporarily deprived them. "A fair deal: we've nothing to complain about. See that our involuntary guest, Count Otto What's-his-name, is not overboard."

The Lieutenant-Commander spoke with the admiration of a true sportsman. For once a U-boat had fulfilled her legitimate purpose by torpedoing a warship. The destroyer had taken the risk, and she had fallen a victim to the powerful Schwartz-Kopff torpedo.

It was apparent to every man on board that the Bolero was doomed. The German torpedo-boat had acted the part of a decoy, and had lured the British destroyer athwart the track of a lurking unterseeboot. At a range of three hundred metres the kapitan-leutnant of the U-boat felt sure of his prey; so much so that he decided that one torpedo was enough.

Hit abaft the boiler-room, the Bolero was practically broken in twain. Her watertight bulkheads were holding, but had been badly strained. Even at the most sanguine estimate it was doubtful whether the bow and stern portions would be able to keep afloat for more than twenty minutes.

Meanwhile there was much to be done. While the signalmen were sending up rockets and firing Verey lights—for the concussion had put the wireless completely out of action—the task of getting away boats and rafts was proceeded with. The wounded were first lifted into the boats, for the explosion had taken heavy toll of the heroes of the engine-room and stokeholds. Already the Lieutenant-Commander had thrown overboard the confidential signal-books and log. Impassively he stood upon the bridge, awaiting the end. His duty was almost done. By virtue of the glorious and imperishable traditions of the British Navy he stood at his post until the last man was clear of the sinking ship.

Deftly, and without the faintest suspicion of panic, the crew took to the boats and rafts. The survivors of the engine-room staff, coming straight from the heated and confined space below, were ill-conditioned to withstand the bitter coldness of the night. Lightly-clad they stuck it, accepting with grimly-expressed thanks the offers of additional clothing from their better-clad messmates.

From the first it was apparent that the boats and Carley rafts were insufficient to accommodate all the ship's company, yet not a man moved out of his turn. Donning lifebelts, those who were unable to take to the boats, without risk of overcrowding and endangering the lives of their messmates, prepared for their long swim, confident that help would be assuredly forthcoming to "hike them out of the ditch".

"Pull clear, men!" shouted Trevannion. "Good luck!"

Standing at the head of the bridge-ladder, and holding on to the stanchion-rail, for the destroyer was listing excessively, Seton watched the scene with feelings akin to admiration. For himself he cared little, or rather, in the grim excitement of the destroyer's last throes, his mind was fully occupied with the episode of the final moments.

"Jump for it, Seton!" shouted the Lieutenant-Commander.

Alec shook his head.

"I'll stand by till you're ready, sir," he replied, proffering a life-belt to his superior.

Trevannion waved it aside with a grave, gesture of refusal. To him, as captain of the ship, it seemed unbecoming that he should don the life-saving device.

"Thanks," he replied. "I'm a good swimmer. I'll find something to hang on to. By Jove! Seton, the men are simply splendid."

The end came with startling suddenness. With two successive reports the sorely-tried bulkheads gave way under the terrific pressure of water. In a smother of foam the riven hull sagged until bow and stern reared themselves in the air to such an extent that to Alec it seemed as if the two extremities would meet. Then, with a sickening movement, the Bolero plunged to the bed of the North Sea.

Seton's first sensation of the plunge was that of intense cold. The moment he felt himself off his feet he struck out to clear the wreckage. In spite of his efforts he found himself being drawn back as surely as if he were held by a chain. Down, down, down! Would the horrible descent never end? He held his breath, struggling the while to force himself to the surface. Already his lungs felt on the point of bursting.

"Good heavens! I'm foul of something," was the thought that flashed through his mind.

It seemed like an eternity, that slow and remorseless suffocation in the icy-cold water. His eyes were wide open, but he could see nothing. Involuntarily he gasped; an inrush of water followed; a moment of intense irritation, and then a period of utter insouciance. His senses were deserting him. In a vague sort of way he realized that he was drowning.

Suddenly the downward movement was arrested. Caught by the upward rush of air from a burst compartment Seton was impelled to the surface with incredible speed. He was conscious of being shot almost clear of the water, of a rush of life-giving air into his partly water-logged lungs; then of striking out almost automatically.

The sea was horribly cold. Hampered by the weight of his clothes, for, with the exception of his great-coat and sea-boots, he had "taken to the ditch" fully-clad, it was a hard struggle for Seton to keep himself afloat.

With a noise like a small pistol-shot the water hitherto pressing against his ear-drums dispersed, and his sense of hearing was restored. Above the hissing of the waves he could hear shouts of encouragement and cries for aid from his struggling shipmates. There were swimmers all around him. Some men were clinging to oars and pieces of floating wreckage. Others were supporting their less robust comrades, while a few dauntless spirits were singing, or rather trying to sing, in order to convey the impression that they still had their "tails up".

Someone pushed an empty water-beaker almost in Alec's face, with a jerky invitation to "Hold on to that, chum."

"Thanks," gasped Seton breathlessly.

"Lumme, if it ain't our sub-lootenant," exclaimed his benefactor. "Goin' strong, sir? Shall I stand by and give you a hand?"

Seton was glad of the moral assistance, although he continued to hang on to the barrel with little effort. For some moments neither man spoke.

"Bout time the old Triadur showed up sir," remarked the bluejacket. "Sure I won't forget to-night, an' it's me birthday. You all right, sir?" he added anxiously.

"Quite," replied Alec untruthfully, but with a dogged determination to refuse to acknowledge that things were not going at all well with him. An ominous numbing sensation in his arms and legs told him plainly and unmistakably that the icy cold water was beginning to take effect.

Almost directly after he had given his assurance, Alec relaxed his grasp of the beaker and without an effort disappeared beneath the surface.

CHAPTER V

In the Whaler

Count Otto von Brockdorff-Giespert's feelings were far from comfortable when the crash of the Bolero's quick-firers told him unmistakably that the destroyer was in action.

With his broken collar-bone and other injuries he was practically helpless, while to make matters worse, as far as he was concerned, his captors had put him under lock and key. Evidently these English meant to take no risks, he soliloquized.

It was no exaggeration to state that he was in a blue funk. At one moment he cursed the German vessel for replying to the British destroyer's fire; at another he hoped and prayed that the former would draw out of range. Not once did he express a wish that the Black Cross Ensign might prove victorious.

With the perspiration oozing in large beads on his bullet forehead he lay and quaked, his mind torn with agitated thoughts. He remembered vividly—the reminiscence was frequently in his mind—how on one occasion, when he was in command of a U-boat, he had taken out of a badly-damaged boat an old, white-haired British
