CHAPTER IX--ON A SUBMARINE CHASER

Very shortly after Huerta resigned the presidency of Mexico and made his

get-away, the ex-Kaiser let loose the war-dogs of Europe and here I was

signed up for four years in the Navy and, I figured, didn’t stand a

ghost of a chance of breaking into the fight. It seemed to me a pretty

tough deal that old Huerta could resign his job while I, a free American

citizen, couldn’t quit, resign, go-over-the-hill, or anything.

What I wanted to do was to get over to England and _sign up_ there for

it was dollars to doughnuts in my mind that there would be some small

bickerings going on between the British and the German navies and it

would be well worth while to see those big guns get into action. I

hadn’t the remotest idea, then, that the _Imperial German Navy_, as

those _boches_ so loved to call it, would be afraid to come out in the

offing and put up a fight. But when it came to torpedoing unarmed

passenger ships loaded with women and children, or hospital ships

carrying wounded soldiers they were right there Fritzy-on-the-spot with

their _blackheads_ as they called their Whitehead torpedoes.

While the ex-Kaiser’s navy could not be induced to leave its

mine-protected harbors and do battle with the British fleet--no, not

even if all Germany starved to death--crafty, old Admiral von Tirpitz

began to build up a frightful fleet of U-boats with the avowed intention

of sinking every merchant ship, no matter what flag she flew, if she

carried foods or munitions to England and her Allies.

As the United States was shipping cargoes of both of these commodities

to Great Britain and France, which was entirely within her rights

according to international law, it was not long, as you can imagine,

before the German U-boats were sinking our ships and killing our men.

It was bewhiskered Admiral von Tirpitz who figured out and showed the

ex-Kaiser that the only way left open for Germany to win the war was to

sink every ship afloat that did not fly the German flag, and soon after

this program was agreed to by the war-lords they seemed in a fair way to

succeed, for they were sinking ships faster than the Allies and the

United States could replace them.

Any number of schemes to beat the U-boats were thought up and while most

of them were quite impracticable there were a few that proved effective

when put to the test. One way was to build more merchant ships every

month than the U-boats could sink and when Uncle Sam put the job into

Mr. Schwab’s hands this was done. Another plan was to hunt down the

U-boats with _submarine chasers_. A submarine chaser is a small,

high-speed boat carrying one or more rapid fire guns.

As you know a submarine can shoot a torpedo at the biggest ship afloat

and if it hits her she is sure to sink in a few minutes and yet it is

the easiest thing in the world to send a U-boat to the bottom if you can

only get a chance to land a shell on her.

Just before we got into the war Germany built two great submarines each

of which was over 300 feet long. One of these U-boats was the

_Deutschland_ and the other was the _U-53_, and both had a cruising

radius of about 5,000 miles, that is, they could travel that distance

without having to take on food or fuel.

No one here ever thought that a submarine could make a trip across the

ocean but the _Deutschland_ did it. She left Bremen, Germany, and

submerged while in the river, then she slipped out into the seaway under

the British fleet that had the German warships bottled up, made the

passage of the North Sea on and under the water, thence through the

English Channel going this dangerous route entirely under water and

across the Atlantic Ocean during which she submerged only when she saw

some of the Allies’ warships.

Then one fine morning, 16 days later, she came to the surface in

Chesapeake Bay and docked at Baltimore. There she unloaded a cargo of

dye-stuffs and synthetic gems and took on a cargo of rubber, and, what

was of more importance, secret papers which Count von Bernsdorf,

Germany’s ambassador to the United States, could not trust to go any

other way. On sailing she made her way to the mouth of the bay,

submerged to escape the British ships which were laying in wait for her

beyond the three mile limit and returned to her home port. Later on she

made another round voyage with equal success.

When we got into the war it was clear that we had a _war-zone_ right

here at home and one that was not to be sneezed at, for, since a

submarine could be built large enough to travel the whole distance from

Europe to America without having to be convoyed by a base, or

_mother-ship_ as she is called, Germany could as easily send over to our

shores one or a dozen submarines as large as the _Deutschland_, fitted

out with rapid-fire guns and torpedoes and do a lot of damage to our

shipping and even to our cities. The _Navy Department_ believed that the

best way to protect our coast was to build a large fleet of U-boat

chasers and this work was gone ahead with as fast as possible.

Now while I can use a key with my left hand nearly as well as I could

with my right, still my arm pained me a good deal and I could have

gotten a long leave of absence if I had asked for it. So when I told the

commander I wanted to be transferred to a U-boat chaser he fixed it O.

K. for me and I was assigned to the _Second_ _Naval District_ which

patrolled from Newport to the First and Third Naval Districts.

The chaser I was assigned to was a brand-new one just off the ways and

of the very latest type; she had a length of 110 feet, a beam a little

under 15 feet and a draft of about 4 feet. She was built chiefly of wood

but she had a pair of steel masts and a crow’s nest for the _lookout_

whose job it was to watch for U-boats. She was powered with a steam

engine but instead of coal she burned oil under her boilers. Her large

size made her very speedy and she could do 25 knots, if she had to,

which was twice as fast as the fastest U-boat could do.

The aerial was stretched between her masts and the leading-in wire was

connected to it near the rear mast and followed it down to the deck

where it passed through an insulator in the latter, and on into the

operating room. This was about the smallest space I ever got into which

was graced by the name of an operating room but I had no _kick_ coming

as we were not afloat all the time.

The sending set had a ½ kilowatt transformer and the receiving set was

fitted with both crystal and vacuum detectors; the whole space taken up

by them was probably not more than 5 cubic feet. Well, so much for the

chaser.

There were only 14 men in our crew and there was far less formality on

board than on a battleship. Bill Adams and I got to be pretty good pals.

The first time I met him he was trying out one of her Hotchkiss

semi-automatic guns and I was watching him.

“Where did you get that chunk of mud?” he queried as he pointed the gun

at an imaginary U-boat.

“Speaking to me?” I asked in turn.

“You said it,” he replied bluntly.

“If you refer to the sparkler on my annularis finger I have to inform

you, sir, that it came from the land of the Raripunas about 1500 miles

up the Amazon river,” I explained with great perspicacity.

You see, I had had the diamonds cut that Princess Mabel gave me and the

one I wore was a _regent_ weighing about 2 carats and it was mounted in

a Tiffany setting. In fact it was altogether too big a diamond for any

ordinary blue-jacket to come by honestly.

“That’s where it came from, but I’m askin’ you, as man to man now, where

did _you_ get it?”

“Right where it came from,” I put it straight back to him.

If it hadn’t been for my _game_ arm I guess Bill and I would have

settled the mooted question as to where my _chunk of mud_ came from by

referring it to the court of last resort, by which I mean the manly art

of _hit-’em-again, gob_.

“Put up your dukes,” commanded Bill at the same time striking an

attitude of a gas-house slugger.

Now to get my right hand up I had to lift it with my left and when Bill

saw this he yelled, “time, you win!”

Then his eyes softened, his voice lost its harshness and he became

sympathetic. He wanted to know how it happened and all about it. And

then we got the matter of the chunk of mud straightened out to Bill’s

satisfaction. From that time on Bill and I were pals and we used to swap

stories. He had been in every corner on the face of the earth except

South America and his stock of experiences was a large one. To keep even

with him I had to manufacture tales out of raw material as I went along

and I often thought he did the same thing. Say, he certainly put over

some regular crawlers. He never got tired of talking about the prospects

of mining diamonds in Brazil and all I had to do to get him going was to

flash my sparkler on him and he was transported as if by magic to

equatorial South America.

Like dozens of other fellows I have met, Bill was a strange

contradiction of brains in that he was a natural born hard boiled egg

and yet when a fellow needed a friend he was as compassionate as a

Salvation Army lass in a trench under fire; again he was ignorant, yet

wanted to learn. For instance he wanted me to teach him wireless; it was

all vague and intangible to him. He had to have something he could see

in three dimensions instead of having to visualize it in his mind; his

one big talent lay in his being able to hit a target with a projectile

of small or large size and accordingly he was able to serve his Uncle

Sam nobly and with telling effect.

You may or may not know it but a fellow can join the navy and live

aboard ship a long time and still know but very little about any part of

her, except his own particular branch, unless he keeps his eyes and ears

open and talks with fellows who know and can and will answer his

questions intelligently. Bill was ignorant when it came to book-learning

but he knew all about submarines and submarine chasers from their

bottoms up.

I had asked him why it was that a torpedo from a U-boat couldn’t hit a

submarine chaser and also to tell me something about the fighting

qualities of U-boats.

“You see, matey,” explained Bill wisely, “the torpedoes made for the

Kaiser’s U-boats are adjusted so that after they are shot from their

tubes they run through the water at an even depth of between 8 and 9

feet below the surface. Now a boat of any size draws far more water than

this and, of course, if the torpedo hits her at all it will be below the

water line and she goes down. But this chaser of ours draws only 4 feet

of water and so a torpedo, if it behaves itself, would pass clean under

her and never touch her.

“The trouble is,” he went on, “that there never was a torpedo made that

stuck to its course and it is liable to shift to the port or starboard

or to come to the surface and for this reason we never take a chance but

dodge them. You can always tell when a torpedo is coming by the thin

white wake she makes on top of the water and while a ship can’t get out

of its way, a speedy little boat like ours can make a quick turn and

give it a wide berth.”

“Who got up the idea of a submarine chaser?”

“Well, that I don’t know about, matey, but I do know that when Germany

sent out her first U-boats to the coast of Great Britain to sink her

ships, all sorts of motor boats which had a length of 40 feet and over

were pressed into service; these boats had guns mounted in them and they

combed the sea in search of the submarine enemy.

“The first German U-boats were slow old craft and they stuck close to

the coast where the ships were the thickest. This made it easy for the

British armed motor-boat patrols to hunt them out and send them to the

bottom. It was soon seen that larger and faster patrol boats carrying

heavier guns were needed to keep up with the newer and faster U-boats

that were sent to take the place of those the British sunk and so speedy

80 foot boats were built specially for patrolling.

“By the time we got into the war the U-boats were so big and fast that

to catch them we had to have regular torpedo boats, except they are

without torpedoes, built to run them down and this is exactly what this

chaser we are now on is. With our chaser we can go twice as fast as any

U-boat the Germans ever sent out and I’m telling you, matey, that if I

ever spot a U-boat coming to the top and she is inside the range of this

Hotchkiss her crew might just as well kiss the Kaiser good-night.”

The way the submarine chasers work is like this: A base is set up on

shore close to that part of the coast waters, or _zone_ as it is called,

that a squadron, which is formed of a dozen chasers has to patrol. The

shore base is fitted up with living quarters for the crews of the

chasers, besides reserve crews who may be needed in an emergency, and

there are also artificers, that is mechanics, carpenters, painters,

etc., who stayed on shore so that when we were relieved from duty and

came in, our boats were looked after as carefully and overhauled as

thoroughly as a millionaire’s automobile.

The base also has a wireless station and any chaser can get in touch

with it should occasion arise for her to do so. Each base also has one

or more destroyers which carry heavier guns and these are stationed near

by so that should the enemy loom up and prove too much for the guns of

our chasers the larger boats can be signaled to help.

When a squadron of chasers leaves its base for the zone it is to patrol

it is split up into two divisions of six boats each and a _division

officer_ is in charge of each one. Each chaser is given a certain area

to patrol and she works with all the other chasers in her squadron, the

shore station and ships at sea. If a U-boat has been sighted at sea, the

ship who has picked her up immediately sends a wireless message to the

base which in turn informs the commander of the squadron.

Should a U-boat venture into one of our zones the chasers get as busy as

hornets and scout around until she either slips away or comes to the top

to enable her commander to take a look around through his periscope to

see if there is a ship in sight worth using a torpedo on.

Besides the regular wireless set each submarine chaser is fitted with _a

sound conduction_ _signalling system_ and this is used to detect the

presence of a U-boat when it is submerged and cannot be seen, though to

do this the enemy boat must be near-by. This conduction scheme is very

simple and you’ll get me fine as I explain it.

[Illustration: Telephone receiver with iron rods]

Water, as you know, conducts sound waves to much greater distances than

air does. You must have often made the experiment when in swimming of

ducking your head under water and listening while another fellow would

strike a couple of stones together under water at a distance of thirty

or forty feet away from you; and yet you could hear them click as they

struck each other as plainly as you could in air a couple of feet away.

Now, signalling between submerged submarines or a submarine and a chaser

is carried on on exactly this same principle, that is by the conduction

of sound waves through the water. To do this kind of wireless signalling

each submarine has a high-frequency sound producing apparatus, or

_oscillator_ as it is called, attached to the hull. It consists of a

diaphragm, or disk, that is set into very rapid vibration by means of an

electromagnet, just as the diaphragm of a telephone receiver is made to

vibrate by its electromagnet.

The disk, or diaphragm, which is very much larger than that of a

telephone receiver, sets in the water and when it is made to vibrate by

closing the circuit with the key it sends out trains of sound waves to

considerable distances through the water.

The other submarine, or chaser, is fitted with a like disk which is

fixed to a _microphone_, or telephone transmitter, and to this a battery

and telephone receiver is connected. When the high frequency sound waves

from one submarine reaches the second submarine they impinge on the disk

of the microphone when it vibrates; this varies the battery current

flowing through the microphone and you hear the dots and dashes in the

receiver.

Now when a U-boat, or any other kind of a power vessel, gets within a

certain range of the chaser the hum of the machinery in her sets the

hull into vibration and you can hear it in the receivers. So, you see,

whether a U-boat is afloat or submerged it is pretty hard for her to

escape the eternal vigilance of the chaser.

We had received word by wireless that a U-boat had been sighted about a

hundred miles off the coast and that she was one of gigantic size. We

swept our area with great zeal, the lookouts in the crow’s nest being

changed every two hours; the gunners were at their guns ready for

instant action and John Paul Jones Boggs, the other operator and I took

turn about listening-in.

I don’t want to brag about myself but I found out a long time ago when I

was a kid operator back home that I had a more sensitive ear than any of

the other fellows, that is, I could differentiate dots and dashes and

take down messages that they could only get as a jumble of signals.

Later on I began to experiment with head-phones and tried out every make

I could get hold of in order to find one that was particularly sensitive

and especially suited to my ear.

When I was chief wireless operator on the _Andalusian_ I met operators

from all over the world. Once when I was in London I scraped up an

acquaintance with a young Swede and he had about half-a-dozen pairs of

head-phones that he had picked up in different countries. Telephone

receivers for wireless work are like violins in that no two of them are

alike and you can’t tell by their appearance what they are really worth;

like violins, too, telephone receivers improve with age provided the

magnets are made of the right kind of steel and properly tempered.

One of the pairs of head-phones this Swede operator showed me was made

in Sweden by the _Ericsson Telephone Manufacturing Company_, and it was

by far the most sensitive phone I had ever used. I bought the pair off

him for a _sovereign_ but they are worth their weight in gold. With this

pair of Ericsson’s on my head I was listening-in for all I was worth. I

kept this up intermittently for about 6 hours when I was rewarded by

hearing the faint whirring sound of a propeller. I reported it to my

commander and he said it was a U-boat all right.

He had our engine stopped so that I could hear her to the best

advantage. The sound of her machinery through the water got a little

louder and then stopped entirely and we guessed that she was resting.

Not to be fooled we stuck right to our posts another five hours but

there was nary a sound from her.

Then the lookout in the crow’s-nest telephoned down that he had sighted

the periscope of a U-boat. Did you ever see a field of race horses just

before the signal was given them to start? Well, every man-jack of us

felt just as high strung and spirited only we didn’t show it. The

commander ordered me to signal all the other U-boat chasers of our

squadron to join us.

The U-boat had come to the surface so that her captain could take a look

around and see if there was a ship in sight that was worth sinking.

Seeing nothing but our little boat the U-boat came _awash_, that is her

conning tower projected above the water and her deck was just level with

the surface of the sea. The captain of the U-boat was evidently

observing us through a port from the inside of the conning tower and

seeing that our guns were manned and that we were making for her at full

speed he had ordered her guns to be brought into action. Each gun was

mounted on her deck in a gun-well and was hoisted into place together

with its gunner by a plunger worked by compressed air.

We closed in on her and then the shells began to fly. A high sea was

running so that it was well nigh impossible for her gunners to hit us or

for ours to hit her, but soon a shell, bad luck to it, carried away one

of our masts and my aerial with it. I rushed up on deck and there I saw

eight or ten of our little chasers heading for the U-boat, which was the

_U-53_, the largest submarine that Germany had turned out with the

exception of the _Deutschland_.

As each chaser came up the fight got hotter but the U-boat stayed in the

game until her captain saw our destroyer coming and then he concluded it

was time to submerge her. We knew her captain had given the order to his

wheelsman to make her dive for her guns and gunners began to disappear

in the deck-wells and in a few seconds the covers closed down on the

latter watertight. Her hatches were closed and her engines, which had

been started, propelled her slowly through the water which must be done

to make her dive at the proper angle.

[Illustration: “A BRIGHT FLASH OF BLUE FIRE SHOT UP THROUGH THE HOLE”]

Just as her bow submerged Bill put over a shell with a _bow trajectory_,

that is, he aimed his gun so that when he fired the projectile shot high

into the air and seemed as if it would go far over the U-boat. But Bill

knew what he was doing and the shell fell squarely on the U-boat’s deck

just aft her conning tower.

Having found the range he planted three more shells on her with

marvelous accuracy; the last one went through her bow and must have

exploded in her torpedo room for a bright flash of blue fire shot up

through the hole for fifty feet and this was followed by a dense

greenish smoke that rolled out as though she was a blast furnace.

After a couple of misses Bill landed another shell on her stern and this

one ripped an awful hole in her; the water poured into her and amid a

series of explosions that threw steaming water into the air like young

geysers, with much sizzling and hissing she went down stern-end on never

to rise again.

A great hurrah went up from all hands on our boat and our Commander

commended Bill on his excellent shots.

“Three cheers for big Bill,” I shouted and the gobs responded with

mighty lung-power.

“That’s the way to swat ’em, eh, matey?” remarked Bill with grisly joy

as we were cleaning away the wreckage.

“I say it is, Bill,” I made reply.
