British Secret Service During the Great War Part 8

"Sent your housemaid Sarah Jones to Felixstowe 4 o'clock this afternoon,"

on being coded would read:

"Five submarines pa.s.sed Lowestoft at 4 o'clock this afternoon steaming south."

Any reference to an illness meant that damage had been done, or that a vessel had been adversely affected to some extent. Any reference to a marriage or engagement meant that a combat or battle had taken place.

"In bed" conveyed the news that a s.h.i.+p or s.h.i.+ps had been sunk. "Put to bed" meant sunk, annihilation, or defeat, according to the context; mention of "delirium or head sickness" conveyed suspicions, or suspicious circ.u.mstances; "doctor called in" that the enemy (or others, as the context might convey) had retired, or been put to flight, whilst any direct, or indirect, reference to "remaining here, or at some named place," that the object or objects in question were still there or likely to remain.

The above-mentioned outline should be sufficient to convey to the reader an idea of how the stunt worked out in practice.

That these messages were often tapped and became the subject of racking headaches to the code decipherers who attempted to unravel them, was quite probable. When we could we tried on the same thing ourselves; such was considered only fair in love as well as in war. Lady telegraph and telephone operators are sometimes amenable to flattery and judiciously administered attentions. It is also within the bounds of possibility that an occasional one might be met with who might not object to test a communication with a semblance of reason; whilst one of the most interesting enemy codes we managed to intercept during our rambles was confined to the limits of a postage-stamp. It meant not only intercepting the letter or postcard but having to unstick the stamp and test it before the message could be copied.

It is not at all necessary, however, to pursue this subject further, but once upon a time during the continuance of this war a certain message was handed in at a certain telegraph office in Holland to cable to a certain address in the U.S.A., which ran as follows:

"Father dead."

The telegraph operator, for some reason which we need not trouble to inquire into, altered the wording to "Father deceased," and then despatched the message in the usual manner.

Immediately came back the reply:

"Is father really dead _or only deceased_?"

The following up of that simple message cost one Government a considerable sum of money, but it was well worth the outlay.

To those who seek the sunny side of life, humour can be found in all things. Once at a funeral, when the author was broken in body and soul with the painful agony of dry tears, kind Providence sent relief from an unexpected quarter. In the pew immediately in front were seated two mourners, one a tiny man, the other about 350 lbs. in weight, whose head was nearly as big as the puny man's whole body. On leaving the church for the graveside each took the other's hat by mistake and they got separated in the crowd. At the close of the service they unconsciously and solemnly put on the hats they respectively held. That of the tiny man did not find resting-place until it had covered his head, ears, and face, and settled on his shoulders. That of the enormously fat man looked like a pea on a drum.

Likewise it was with our local code messages. Their use in practice was often the innocent cause of much trouble; more often, perhaps, the source of some humour. The gentle cherub who had undertaken the collection of messages and who has recently been hereinbefore referred to, maybe received another shock to his domestic bliss; and that only a week after the one before related. It is much to be feared that he did not fully appreciate the humorous side. However, as it gives an excellent ill.u.s.tration of the practical and simple working of the last-mentioned code, it is narrated.

The facts are as follows:

I one day received this request.

"I shall be exceedingly obliged if you will undertake to deliver this package to ---- personally. If you could start at once it would be very good of you; but please understand, no living soul may see the contents of this packet except ---- himself."

I bowed my acceptance of the mission, murmuring how honoured I felt at an opportunity to render service to the ill.u.s.trious personage soliciting my a.s.sistance. Then I hastened to my hotel to prepare for immediate departure.

The midnight express to ---- was crowded. On the platform a few minutes before the scheduled time of leaving, representatives from almost every country in Europe could have been picked out. Detectives and Secret Servant agents glided through the crowd, observing, watching and noting the many strange and familiar faces. Their work meant an added consumption of current on the wires. The vacant stare, the side glance, or the wooden far-away expression of countenance, conveyed much to these men. To them it was always interesting to try and read the working of the brain behind. But I was a traveller and the doings of these night-hawks interested me but little, beyond such casual observation as could be made during a quick pa.s.sage to the train.

In the corridor of the car to which I was allotted were several Germans.

Two in particular I instinctively feared. Their faces were familiar. One of them had secured a berth in my compartment, and addressing me in excellent Danish, showed a desire to be affable. It was unsought, but it would perhaps be dangerous not to reciprocate.

Soon after the train had started on its journey I politely offered to share some refreshment with this fellow-traveller, which, however, that astute gentleman politely but firmly declined. It was an easy matter to guess the suspicious working in his mind. He meant to pa.s.s a sleepless night. So did I.

In due course I retired to rest, and the German secured the door of the cubicle before climbing to his berth, which was above mine. As soon as he was comfortably settled I opened the door he had closed. The German waited a while, and then, very stealthily, shut it again. I waited about a like period and reopened it. So the game proceeded, until about four o'clock in the morning the German complained of the draught. In the most polite language that could be commanded I replied by commenting upon the extreme heat and the unhygienic practice of curtailing fresh air.

At 6 a.m. the German decided to seek another car, at which I inwardly rejoiced exceedingly. No sooner had he departed than I secured the door and enjoyed a refres.h.i.+ng sleep of several hours.

Later that morning the door-closing German was observed in close consultation with his companion. On a ferry which had to be crossed both of them watched my every movement, and I began to congratulate myself in that I had taken precautions before departure in order to guard against contingencies.

Forearmed is forewarned. Before leaving I had prepared another packet in exact duplicate of the original I had been entrusted with. The dummy contained only an old newspaper, and it was placed in an inside bank-note pocket of my waistcoat. Its outline could have been detected by anyone on the look-out for it. The original packet was elsewhere concealed, in a secure hiding-place, where it was least likely to be sought or found.

On leaving the ferry a rush was made at the gangway and I found myself involuntarily pushed forward and wedged in between the two over-night observers. I could feel their hands run over my chest, so I took some interest in the proceedings. I had not been on numerous race-courses, nor partic.i.p.ated in football, boat-race night, and other big crowds in England, without learning something of the ropes. Every time a hand entered the inside of my coat it encountered small steel obstacles which lacerated and hurt. True I lost a few b.u.t.tons, and my clothes were damaged, but the dummy packet remained intact, and I noticed with some satisfaction afterwards that one of the two gentlemen before mentioned had a hand bound up in a pocket handkerchief when they boarded the waiting train.

On arrival at ---- my taxi-cab was followed. Having been a constant visitor to the town in question for many years I redirected my driver to a public building which had a bolt hole at its back, by the use of which my pursuers were baffled successfully, and the package was safely delivered without further trouble or anxiety. After which I despatched the following cablegram:

"Child delivered safely this morning mother doing well."

Whether this message was also intercepted by the jealous wife of our temporary receiving agent, history does not relate, but I tremble to think of the volcanic domestic eruption which must have ensued if it were so.

When war was declared, cables were cut, a most rigid censors.h.i.+p installed, and no printed matter was allowed to leave England. Yet news, most important news, continued to leak through to Germany, and most of it went through neutral countries.

Before the war, Germany used cyphers, but these were soon dropped. It is common knowledge that every Government keeps a copy of all cypher and code messages sent over the cables from every Emba.s.sy or Consulate, whether the countries are at peace or war. The great cleverness of certain men at unravelling any code, however complicated, is also openly acknowledged.

Yet, in spite of every precaution and all science and knowledge the country could bring to bear, news continued to leak through and to fly across the North Sea. Scotland Yard, to which admirable inst.i.tution the whole world owes so much, was put upon its mettle. It proceeded to watch with still closer scrutiny certain suspected persons who still claimed the privilege of freedom. One of these was a small London tradesman whose premises were situated in a remote and quiet back street. He appeared to have rather more corresponding friends than his position or his business justified. His correspondence, in and out, was intercepted, copied, and sent along in a manner not likely to arouse his suspicions.

Nothing, however, occurred which could be looked upon as even suspicious, until one day a telegram arrived which had been handed in at a certain naval base of some importance in the U.K. It simply said "Been ill three days--John," or words to that effect.

Now the sender had also been watched, an attention which had been evenly divided amongst every one of this tradesman's correspondents. The police knew that the sender of the message, "John," had been in perfect health for quite a long time past, which fact was, of course, communicated to headquarters.

The information caused a flutter in the official dovecots.

Copies of the message, with comments, were forwarded to the War Office, to the Admiralty, and to other Government Departments likely to be interested.

To shorten the story, certain gentlemen in the Admiralty were amazed when they remembered vividly that secret orders had been issued by them which commanded a squadron of wars.h.i.+ps to leave the port at which the message had been handed in, and join up with the High Seas Fleet _exactly three days_ from the date of the aforesaid message.

Needless to add that the further activities of both the sender and the receiver of the telegram were forthwith promptly crushed, once and for all future time.

Scotland Yard also discovered, probably with considerable a.s.sistance from the Censors.h.i.+p Department, that the Germans were successfully getting out information useful to them through open business letters addressed to residents in neutral countries, particularly Norway, Sweden, Denmark, and Holland, which were decoded by adding certain geometrical figures. For example, where the sides of an added triangle or triangles intersected one another, or cut the rim of a circle, there would be found the words used in the secret messages.

Several of these ingenious codes were described in a most interesting article which was published in _Pearson's Magazine_, October, 1918, with ill.u.s.trations which more clearly demonstrated their latent meaning. Two of the most brilliant of them were the knot alphabet and the chess problem.

In the former case a parcel sent to a supposed prisoner in a German internment camp was found to contain, amongst other things, a woollen sweater, or knitted sports vest. It was apparently so badly knitted, and the wool was seen to be so full of knots, that the censor's suspicions were aroused. Subsequent searches revealed that no such person as the addressee of the parcel in question was known to exist. His name certainly did not appear in any Army List. The aforesaid garment was most carefully unravelled. The wool was found to be whole, with a mult.i.tude of simple knots tied at irregular intervals. Alphabets were written on a board, each letter being placed at given distances apart, and very soon a most interesting message was read off.

The chess problem was deeper in its cunning and its intricacy. During 1917, a young and fascinating actress appeared in Paris. She was suspected and closely watched. In due course she captivated one of the junior secretaries of a neutral Emba.s.sy. His integrity was absolutely beyond all doubt, but naturally he also was watched and shadowed in order to learn what was pa.s.sing, or might be pa.s.sing, between them or otherwise.

The watchers' notes, on being compared, revealed certain facts which when carefully pieced together laid bare the whole plot. The actress professed to be deeply interested in the serious game of chess. She inspired a similar pa.s.sion in the breast of the young and inexperienced attache. One day she produced to him a rough ill.u.s.tration of an alleged chess problem which she had cut from a local newspaper; in all probability she herself had indirectly caused its publication. She worried her admirer unduly to help her solve what had been, or were, the opening moves in the game which had caused the pieces to be left on the board as shown in the sketch. No one in Paris could be found who could enlighten or help her; at least, so she represented.

Gentle interrogation of the attache by his inamorata caused him to admit the existence of a chess club of some renown in the capital of the country his Emba.s.sy represented. It was a neutral country which bordered on Germany.
