CHAPTER I

Man Overboard

"WHERE are we now?" asked Oswald Detroit, emerging from the cabin of

the _Diomeda_.

"Ask me another," replied his chum, Jack Hamerton, with a merry

laugh. "We may be here, we may be there, for all I know. One thing I

am certain of: I have just hove the lead, and found that we are in

twenty-two fathoms, with a gravelly bottom. That's good enough for

me. Also, by dead reckoning, we are three hundred and seventy-eight

miles from Lowestoft, and I can't take an observation because of this

fog."

"You don't seem at all anxious," remarked Detroit, who regarded the

wall of thick white mist with evident mistrust.

"Why should I? The yacht's as sound as anyone could desire, and we've

plenty of sea room. Now, if we were anywhere in the neighbourhood of

the sandbanks at the mouth of the Elbe, I might feel jumpy. Take the

helm, old man; north, eighty east, is the course. I'll get

breakfast."

Jack Hamerton was a tall, broad-shouldered fellow of twenty years of

age. He might well be described as thick-set, for his head was set

upon his square shoulders by a short, thick neck, his arms were

brawny, while his legs would have caused many a professional

footballer to turn green with envy. His features were inclined

towards heaviness, the bushy eyebrows and square jaw denoting force

of character amounting to stubbornness.

He was a sub-lieutenant in the Royal Navy, and had lately been "paid

off" from H.M.S. _Blazer_ after an arduous commission in the Persian

Gulf. Owing to the particular circumstances My Lords had granted

Hamerton three months' leave, and the Sub, with an innate love for

the salt seas, had chartered an eight-ton yacht, and with Detroit for

company had started on a cruise to Kiel.

Oswald Detroit was physically different from Hamerton. He was tall,

but slenderly built, yet there was a suppleness in his muscular limbs

that had stood him in good stead in the athletic world. His features

were clean-cut and regular, his hair of a light-brown hue and

inclined to curliness, while his fair skin, in spite of exposure to

the wind and sun, contrasted forcibly with Hamerton's almost swarthy

complexion.

Detroit was an American by birth--a native of Richmond, Va.--and

American in character to his finger tips. He had great faith in his

country, and a heap of self-reliance that had carried him through

many difficult places. His powers of argument were marvellous,

although he invariably hid his most telling points in debate under a

thin covering of dry humour.

It was at Lowestoft that the Sub met his future sailing mate for the

first time, only a few days before the momentous voyage commenced.

Oswald's sister had married a naval lieutenant, a distant cousin of

Hamerton's, and thus the two men came in contact with each other.

In a very few hours a bond of friendship was found, for despite their

physical difference Hamerton and Detroit had a lot in common. Both

were keen sportsmen, and each took a deep interest in yachting, the

American being an active member of the exclusive Marblehead Yacht

Club. When Hamerton spoke of a cruise to the Baltic, with the

crowning attraction of participating in the international racing at

Kiel, Detroit's interest was so marked that it wanted little

persuasion on the Sub's part to induce the American to accompany him.

Accordingly the eight-ton ketch _Diomeda_ was chartered. Although

somewhat small for an extensive voyage across the North Sea, she was

far more seaworthy than many a craft of twice or even thrice her

tonnage. Hamerton fell in love with her at first sight. It was not on

account of her lines, for an almost total lack of sheer, bluff bows,

and rounded run aft were not exactly pleasing to the eye. But there

was a substantial appearance about the craft that was far more

important than artistic curves, while closer acquaintance revealed

the fact that she did not belie her appearance.

Barely twenty-eight feet in length, with a generous beam of a third

of her over-all dimension, and a draught of nearly six feet, the

_Diomeda_ was snugly rigged and canvased.

Her cabin-top was low, offering little resistance to the wind, while

her cockpit, lead-lined and self-emptying, was essential for passages

across the short steep seas betwixt the east coast of England and the

opposite shores of the North Sea.

Descending the short flight of steps leading to the cabin, Hamerton

discarded his dripping oilskin, and methodically hung it on two hooks

in a cupboard devoted to that purpose.

He was in no hurry: he rarely was, save when occasion necessitated,

and only then did his activity become apparent. Otherwise he did

things in a cool, calculating way that seemed in keeping with his

ponderous form.

The cabin was plainly yet comfortably furnished. On either side were

sofa bunks, terminating with spacious lockers screened with curtains.

Two scuttles in the rise of the cabin-top and a skylight overhead

were sufficient to impart plenty of light, but owing to the flying

spindrift these were securely fastened. In the centre of the

linoleum-covered floor stood a swing table, on which was spread a

chart of the North Sea. On the chart lay a pair of parallel rulers

and a dividing compass.

The Sub rolled the chart--placing it in a rack so as to be easily got

at should it be required--dived into the pantry, and produced a

couple of enamel mugs, plates and rather tarnished knives and forks.

Then from another division he hauled out a teapot, some bread,

butter, and a bundle of rashers.

Taking the latter, he made his way along the steeply inclined floor

towards the fo'c'sle.

On the for'ard bulkhead was a clock and a barometer, surrounded by

four signal flags representing the yacht's name in code. The hands of

the clock pointed to a quarter to five, the barometer, 30.01, steady;

both pieces of information Hamerton entered in a rough logbook.

The fo'c'sle was small, and, being battened down, ill-ventilated. The

heat from the Primus stove and the odour from the frizzling bacon,

combined with the erratic pitching and listing of the yacht, would

have upset many an experienced sailor, but unperturbed the amateur

cook proceeded with his self-imposed task.

"On deck, there!" shouted Detroit, raising his voice to make himself

heard above the roar of the atmospheric stove.

There was something urgent in the tone of the American's voice.

Hamerton backed out of the narrow fo'c'sle door, and, without waiting

to put on his oilskin, ran up the ladder and gained the cockpit.

The fog was not so dense as it had been ten minutes previously. The

rising sun had partially dispelled the white wall of vapour, so that

it was possible to see about fifty yards ahead.

"Listen!" exclaimed Oswald.

"Yes, I hear," replied the Sub. "A steamer of some sort, tearing

along at a furious pace. A quarter of a mile off, I should say, but

close enough in this mirk."

With that Hamerton snatched up a fog trumpet that lay on the lee seat

of the well, and made the welkin echo to three loud blasts--the

recognized signal of a sailing vessel with the wind abaft the beam.

No reply came from the unknown vessel. Momentarily the noise of her

engines and the swish of water as her bows cleft the waves grew

louder and louder.

"Down helm, sharp!" ordered Hamerton. "What in the name of Davy Jones

is that idiot carrying on like that for?"

Round swung the _Diomeda_ slowly yet surely, but before the sails

began to flap, the disturber of her crew's peace of mind loomed out

of the fog.

It was a large destroyer, painted a dull grey. She was travelling at

close on thirty knots. Dull red flames were spurting from her four

squat funnels. Her decks were being swept from end to end with water,

while the spray, dashing against her funnels, trailed off into wisps

of steam, leaving the fore side of the smoke-stacks bleached with

salt. In spite of the wave-washed decks, men, clad in greenish-grey

oilskins, were standing by the two torpedo tubes on deck, while right

aft stood a seaman holding a red-and-white flag in his extended

hands.

This much the crew of the _Diomeda_ had barely time to take in, for

close astern of the leading destroyer came another, and another, and

yet another, less than thirty feet separating the black cross ensign

of the leading boat from the knife-like bows of the one next astern.

Any miscalculations on the part of the coxswains of the several boats

would inevitably result in disaster.

Just as the fourth destroyer darted past the violently pitching

yacht--for she was in the thick of the combined "wash"--one of her

crew, who was in the act of securing a stanchion rail, slipped on the

heaving, wave-swept deck. Unnoticed by his comrades, he rolled under

the rail and fell into the sea.

The _Diomeda_ was "in irons". Her sails were slatting violently in

the wind. She carried no way, nor would she answer to her helm, and

some minutes elapsed ere the ketch fell off sufficiently for her

canvas to draw.

Running forward and gripping the shrouds, Hamerton seized a boathook.

The unfortunate man still floated, face upwards, but made no attempt

to save himself.

"Guess he's broken his back," shouted Detroit to his companion, in

reply to which the Sub nodded. Falling off a boat travelling at

thirty knots, a man would strike the water with terrific force.

"Now luff!" bawled Hamerton. "Easy with your helm--port a little."

Leaning outwards to the full extent of his left arm, the Sub made a

futile attempt with the boathook to reach the sailor.

"Up helm, and gybe her," he shouted. "We'll pick him up on the next

tack."

Then to his surprise Hamerton saw the American leap out of the

cockpit, steady himself on the waterways for a brief instant, then

plunge into the sea.

"Silly ass!" grunted the Sub, although recognizing Detroit's pluck.

"I'll have two men to haul aboard now instead of one."

With that he made his way back to the cockpit to steady the yacht on

her helm. Then it was that he found that Oswald had acted with

discretion as well as bravery, for before leaping he had taken a turn

of the end of the mainsheet round his waist. Rescuer and rescued were

trailing astern at the end of forty feet of rope.

Hauling the _Diomeda's_ headsails to windward, Hamerton soon had the

yacht hove-to, though forging slowly through the water. It was then a

comparatively easy task to get the mainsheet in until Detroit and the

seaman were alongside. Then waiting till a wave brought the man

within arm's length, the Sub clutched hold of him, and with a

powerful heave lifted him on deck and into the well.

Without assistance Detroit scrambled up, and assisted his comrade to

attend to the rescued seaman.

[Illustration "WAITING TILL A WAVE BROUGHT THE MAN WITHIN ARM'S

LENGTH, THE SUB CLUTCHED HOLD OF HIM"]

"He's alive all right," announced Hamerton. "A lump of a fellow, by

Jove!" he added, critically regarding the stalwart, fair-haired

Teuton. "We'll get those wet clothes off him and carry him below. You

will do well to change. Never mind about the boat, she'll take care of

herself for a while."

The destroyers were now out of earshot, swallowed up in the still

dense watery mist. More than likely the absence of the unfortunate

seaman would not be noticed for some considerable time, and then it

was doubtful whether the vessels of the flotilla would retrace their

course far enough to come in touch with the _Diomeda_.

"I'm glad I didn't miss that sight, by Jove!" said Hamerton, with

unstinted praise. "Those Germans know how to handle their torpedo

craft. Fancy taking them at that bat through a fog!"

"It's fools' work," said Detroit, who was struggling into a change of

clothing.

"All the same, it's part of the game, and only by constant practice

can they keep in a state of efficiency. Our fellows are pretty smart

at manoeuvring, but these Germans appear to run all sorts of needless

risk, and still manage without serious accidents. Finished changing?

Good! You might get on deck and see how things are progressing."

Barely had Detroit resumed his post at the helm when out of the fog

came a succession of dull flashes, punctuated by the deafening

detonation of a number of quick-firing guns. Then, like a veil rent

in twain, the fog partly lifted, revealing a large battleship,

cleared for action, and blazing away with her light armament in the

direction of the small British yacht.
