Meanwhile, what of the supply ship, for I'm supposed to meet her here, and it's already twenty-four hours since yesterday's epoch-making battle and I expect the English any moment.

My doubts were removed for me since I received special orders at noon by high-power wireless from Nordreich, and on decoding them found that, for some reason or other, we are ordered to proceed to Muckle Flugga Cape, and thence down the coast of Shetlands to the Fair Island Channel, where we are directed to cruise till further orders. Special warning is included as to encountering friendly submarines.

It appears to me that a special concentration of U-boats is being ordered round about the Orkneys, and that some big scheme is on hand.

We are now steering south-westerly to make Muckle Flugga, which I hope to do in four days' time if the weather holds.

These Northern waters have proved very barren of shipping in the last few weeks, and this fact, coupled with the approaching winter weather, which must be fiendish in these lat.i.tudes, makes me quite ready to exchange the Archangel billet for the work round the Orkneys and Shetlands, though this is d.a.m.nable enough in the winter, in all conscience.

There is only one fly in the ointment, and that is that this premature return to North Sea waters might conceivably mean a visit to Zeebrugge, though this cla.s.s are not likely to be sent there.

Though it is many weeks since I left Zoe, I have not been able to forget her. I continually wonder what she is doing, and often when I am not on my guard she wanders into my thoughts.

Whilst I am up here, it does not matter much, except that it causes me unhappiness, but if I found myself at Bruges it would be very hard. However, I don't suppose I shall ever see her again.

Sighted Muckle Flugga this morning, and shaped course for Fair Island.

Oh! what a h.e.l.l I have pa.s.sed through. I can hardly realize that I am alive, but I am, though whether I shall be to-morrow morning is doubtful--it all depends on the weather, and who would willingly stake their life on North Sea weather at this time of the year?

Curses on the man who sent us to the Fair Island Channel. Where the devil is our Intelligence Service? If we make Flanders I have a story to tell that will open their eyes, blind bats that they are, luxuriating in the comfort of their fat staff jobs ash.o.r.e.

The Fair Island Channel is an English death-trap; it stinks with death. By cursed luck we arrived there just as the English were trying one of their new devices, and it is the devil. Exactly what the system is, I don't quite know, and I hope never again to have to investigate it.

For forty-seven, hours we have been hunted like a rat, and now, with the pressure hull leaking in three places, and the boat half full of chlorine, we are struggling back on the surface, practically incapable of diving at least for more than ten minutes at a time. Even on the surface, with all the fans working, one must wear a gas mask to penetrate the fore compartment. Oh! these English, what devils they are!

Here is what happened:

Fair Island was away on our port beam when we sighted a large English trawler, which I suspected of being a patrol. To be on the safe side, I dived and proceeded at twenty metres for about an hour.

At 5 p.m. (approximately) I came up to periscope depth to have a look round, but quickly dived again as I discovered a trawler, steering on the same course as myself, about a thousand metres astern of me. This was the more disconcerting, as in the short time at my disposal it seemed to me that she was remarkably similar to the craft I had seen in the afternoon, and yet this hardly seemed likely, as I did not think she could have sighted me then.

On diving, I altered course ninety degrees, and proceeded for half an hour at full speed, then altered another ninety degrees, in the same direction as the previous alteration, and diving to thirty metres I proceeded at dead slow. By midnight I had been diving so much that I decided to get a charge on the batteries before dawn; I also wanted to be up at 1 a.m. to make my position report.

I surfaced after a good look round through the right periscope, which, as usual, revealed nothing. I had hardly got on the bridge, when a flash of flame stabbed the night on the starboard beam and a sh.e.l.l moaned just overhead.

I crash-dived at once, but could not get under before the enemy fired a second shot at us, which fortunately missed us. As we dived I ordered the helm hard a starboard, to counteract the expected depth-charge attack. We must have been a hundred and fifty metres from the first charge and a little below it, five others followed in rapid succession, but were further away, and we suffered no damage beyond a couple of broken lights. The situation was now extremely unpleasant. I did not dare venture to the surface, and thus missed my 1 a.m. signal from Headquarters. I wanted a charge badly, and so proceeded at the lowest possible speed. At regular intervals our enemy dropped one depth-charge somewhere astern of us, but these reports always seemed the same distance away.

At dawn I very cautiously came up to periscope depth, and had a look. To my consternation I discovered our relentless pursuer about 1,500 metres away on the port quarter. In some extraordinary manner he had tracked us during the night.

I dived and altered course through ninety degrees to south.

At 9 a.m. a tremendous explosion shook the boat from stem to stern, smashing several lights, and giving her a big inclination up by the bow.

As I was only at twenty metres I feared the boat would break surface, and our enemy was evidently very nearly right over us. I at once ordered hard to dive, and went down to the great depth of ninety-five metres.

A series of shattering explosions somewhere above us showed that we were marked down, and we were only saved from destruction by our great depth, the English charges being set apparently to about thirty metres.

At noon the situation was critical in the extreme. My battery density was down to 1,150, the few lamps that I had burning were glowing with a faint, dull red appearance, which eloquently told of the falling voltage and the dying struggles of the battery.

The motors with all fields out were just going round. The faces of the crew, pallid with exhaustion, seemed of an ivory whiteness in the dusky gloom of the boat, which never resembled a gigantic and fantastically ornamental coffin so closely as she did at that time.

The air was fetid. I struck a match; it went out in my fingers. The slightest effort was an agony. I bent down to take off my sea-boots, and cold sweat dropped off my forehead, and my pulse rose with a kind of jerk to a rapid beating, like a hammer.

I left one sea-boot on.

At 1 p.m. a deputation of the crew came aft, and in whispered voices implored me to surface the boat and make a last effort on the surface. A m.u.f.fled report, as our implacable enemy dropped a depth-charge somewhere astern of us, added point to the conversation, and showed me that our appearance on the surface could have but one end.

At 3 p.m. the second c.o.xswain, who was working the hydroplanes, fell off his stool in a dead faint.

At 3.30 p.m. the supreme crisis was reached: two more men fainted, and I realized that if I did not surface at once I might find the crew incapable of starting the Diesels.

At the order "Surface," a feeble cheer came from the men.

We surfaced, and I dragged myself-up to the conning tower. Luckily we started the Diesels with ease, and in a few minutes gusts of beautiful air were circulating through the boat.

Meanwhile, what of the enemy? I had half expected a sh.e.l.l as soon as we came up, and it was with great anxiety that I looked round. We had been slightly favoured by fortune in that the only thing in sight was a trawler away on the port beam. It was our hunter.

I trimmed right down, hoping to avoid being seen, as it was essential to stay on the surface and get some amperes into the battery. I also altered course away from him.

It was about 5 p.m. that I saw two trawlers ahead, one on each bow. By this time the boat's crew had quite recovered, but I did not wish to dive, as the battery was still pitiably low. I gradually altered course to north-east, but after half an hour's run I almost ran on top of a group of patrols in the dusk.

I crash-dived, and they must have seen me go down, as a few minutes later the boat was violently shaken by a depth-charge.

We were at twenty metres, still diving at the time. I consulted the chart, but could find no bottoming ground within fifty miles, a distance which was quite beyond my powers.

At 11 p.m. I simply had to come up again and get a charge on the batteries.

From 7 p.m. to 10 p.m., at regular half-hourly intervals, a depth-charge had gone off somewhere within a radius of two miles of me. Needless to say, I was only crawling along at about one knot and altering course frequently. What was so terrible was the patent fact that the patrols in this area had evidently got some device which enabled them to keep in continual touch with me to a certain extent.

These monotonous and regular depth-charges seemed to say: "We know, Oh! U-boat, that we are somewhere near you, and here is a depth-charge just to tell you that we haven't lost you yet." [17]

17. Karl was quite right; it is evident that he had the misfortune to encounter one of our new hydrophone-hunting groups, just started In the Fair Island Channel. The incident of the depth-charges every half-hour was known as "Tickling up." Probably the patrol only heard faint noises from him.--ETIENNE.

As an hour had elapsed since the last depth-charge, I felt fairly happy at coming up, and on making the surface I was delighted to find a pitch-black night and a considerable sea. From 10 p.m. to 1 a.m. I actually had three hours of peace, and in this period I managed to cram a considerable amount of stuff into the batteries. The densities were rising nicely and all seemed well, when I did what I now see was a very foolish thing.

I made my 1 a.m. wireless report to Nordreich, in which I requested orders at 3 a.m. and reported my position, together with the fact that I had been badly hunted.

In twenty-five minutes they were on me again! I had most idiotically a.s.sumed that the English had no directional wireless in these parts. They have. They've got everything that they have ever tried up there; it was concentrated in that infernal Fair Island Channel.

I was only saved by seeing a destroyer coming straight at me, silhouetted against, the low-lying crescent of a new moon. When I dived she was about six hundred metres away. As I have confessed to doing a foolish thing, I give myself the pleasure of recording a cleverer move on my part. I antic.i.p.ated depth-charge attack as a matter of course, but instead of going down to twenty-five metres, I kept her at twelve.

The depth-charges came all right, seven smashing explosions, but, as I had calculated, they were set to go off at about thirty metres, and so were well below me.

The boat was thrown bodily up by one, and I think the top of the conning tower must have broken surface, but there was little danger of this being seen in the prevailing water conditions.

I have just had to stop recording my experiences of the past forty-eight hours, as the Navigator, who is on watch, sent down a message to say that smoke was in sight.

The next hour was full of anxiety, but by hauling off to port we managed to lose it. I then had a little food, and I will now conclude my account before trying again to get some sleep.
