The Zeppelin Destroyer/Chapter XVIII
CHAPTER XVIII
THE TRI-COLOURED RINGS
Almost as soon as we rose we saw straight before us a beam of reddish light moving swiftly northward in the direction of London.
For a few seconds it was shut off, shone out again, and then went out. I knew it to be from a railway engine, the stoker of which had been firing up. Moving trains, notwithstanding the pulling down of carriage-blinds, and the darkening of railway platforms so that persons break their legs in descending, or getting out at a supposed platform and falling upon the line, form the best guides for aircraft at night. By following an express locomotive, which must be stoked at frequent intervals, and looking out for the coloured signal-lights along the line, an airman can always reach the London area. I had, when night-flying at Hendon before the war, often guided myself home by following an up-express.
So terrific was the roar of my new engine that I could only communicate with Roseye by signs.
I pointed at the moving train and, understanding my gesture, she nodded.
As we rose higher and yet higher into the calm starlit sky, the earth beneath us became increasingly mysterious and misty. Here and there dim lights showed, single lights of scattered cottages unseen by rural constables, or improperly obscured lights from the larger houses.
Soon some red and green lights showed away on our left, and I knew that in the valley there ran the main railway line to London.
By day, at an altitude of 2,500 feet, the whole surface of the earth appears perfectly flat, hills and valleys seeming to be on the same level. Therein lies one of the dangers of aerial navigation. The contour of the earth is quite indistinguishable when one is half a mile high, therefore the altimeter is not of very great use—and more especially so at night. The instrument only records the number of feet above sea-level, and not above the earth. Thus, a pilot flying by night can very easily pass over a valley and suddenly find himself encountering a range of high hills with a fatal belt of trees or row of houses.
Such is exactly what happened to us on that memorable night. We crossed the valley, and as I steered straight by compass in the direction of Stockhurst at about thirty miles an hour, I had dipped and of a sudden I found myself nearing a dark, high hill. Just in time I shot up and cleared, I believe only by inches, the roof of a house.
Roseye was quick to notice our sudden ascent and how we skimmed over the house and the trees of somebody's park as we kept our rather zigzag course.
A clever writer upon aeroplanes has, with much truth, pointed out that the natural course of a machine is never a direct one, and if a line could be drawn between two given points it would be found that first it veered slightly to the left of this line, then gradually worked back to the true direction, afterwards heading off to the right and again returning. Thus the true course is in the form of a continuous series of left and right-hand semicircles.
These eccentric semicircles we were making with the engine running like clockwork. There were few clouds and, therefore, the chance of a nasty 'nose-dive' was not to be apprehended. Once a machine gets into clouds it behaves like a ship in a stormy sea, and clouds can easily be met with after a height of three thousand feet.
After passing over the hill I dropped again to 2,000 feet, that being the best height to fly on a cross-country journey. There now opened out to our view a quantity of lights, among which were the red glare of a furnace, and a long row of small lights which evidently marked the main street of some little town in defiance of the 'order.'
I planed down till I could clearly see the obscured lights of a railway station, and by my map, over which my little four-volt lamp was shining, I decided it to be Uckfield. I therefore realized that I was bearing too far south and, further, just at that moment I had a 'bump'—as we call it—or rather I ran into a patch of rarefied air which caused the machine to plunge heavily and tilt.
Righting her, I rose again rapidly to 3,000 feet to get out of the danger-zone and, turning east, discerned in the darkness below me yet another cluster of lights which I approached rapidly, having decided that it must be Buxted.
Still steering south-east I could see, away on my left in the far distance, a number of scattered lights in a long line, denoting where Hastings and St. Leonards lay. Beyond those lights, away upon the dark sea, showed the long beam of a ship's searchlight moving slowly in an arc in the Channel.
Roseye, seated beside me, touched my arm and pointed to it. Again I nodded in response.
By the map I saw we were now approaching that high ridge which stretches from Heathfield across to Burwash, the ridge which overlooks Hailsham and the Pevensey Levels. My altimeter then showed 2,800 feet and all went well for ten minutes, or so, until just as I approached the railway line near Heathfield, we became suddenly blinded by the white beam of a searchlight from below.
Roseye put up both hands to her eyes, but I bent my head and kept on my course.
I saw her put out her hand as though to turn our own searchlight downwards and gripped her wrist, preventing her.
I knew that our approach had been heard by the anti-aircraft listening-post on Brightling Beacon, and that, having picked us up, they would see the tri-coloured rings beneath my planes. Truly it was fortunate that I had had them painted there, for I knew that upon the Beacon they had a very useful anti-aircraft gun.
Beneath my breath, however, I cursed the men with that searchlight for, following us, it blinded us. My first impulse was to turn away from it but, next instant, I realized that to do so might arouse suspicion below and they might open fire. Therefore I kept on though, so intense was the glare, that I could see nothing of my instruments before me, and Roseye sat with her gloved hands covering her face.
As suddenly as it had opened upon us, the light was shut off. The naval gunners on duty below had evidently satisfied themselves that we were not enemies, and therefore, finding myself too far south for Mayfield, I made a semicircle until I again came across a railway line going north. I decided that if I followed it I must find Mayfield station.
It struck me that already Teddy must be hearing my approach. My luminous wrist-watch showed it to be now past ten. Curious how very quickly time passes in the air if there is but little wind, and one's engine is running well. It only seemed as though we had left Holly Farm a few minutes before. Since we had left I had spoken no word with my well-beloved, the roar of the exhaust and the shrill whistling of the icy wind preventing conversation. Yet I could see her well-wrapped-up figure silhouetted against the sky as, seated alert and watchful, she was now on the look out for Teddy's signal.
That we were flying far too high I suddenly realized, therefore I planed down to about 900 feet, and at that altitude we sailed over Mayfield which was, however, in complete darkness, save for a cycle travelling along its main street, and a couple of lights at the station whither the green and red signals had guided us. Passing Mayfield I still descended to 600 feet, and then again circled round, but neither of us could discern any flashing signal.
Teddy had with him a strong electric torch, and we had arranged that he should give me a number of 'shorts' followed by a number of 'longs' in order to tell me that all was clear.
But we could discern no signal!
Still lower I descended and circled about until I had actually picked out the pointed spire of Stockhurst church.
Yet there was still no sign.
Roseye saw how puzzled I had become, and extended her palms to denote dismay. What could have gone wrong? Where was the hitch?
Back I turned over Mayfield again, and once more took certain bearings, for night-flying is always fraught with many difficulties, and one can so very easily get lost. I consulted both map and compass very carefully, satisfying myself at last that I had made no mistake.
I had certainly picked up Stockhurst. But where was the agreed sign?
Something surely must have happened! Why did not Teddy show us his light?
The time was quite correct. We were only ten minutes late. I knew my friend too well to put his silence down to mere forgetfulness.
No. Something had happened!
Both of us strained our eyes into that black, cavernous space below, as we hovered in mid-air full of hesitation and perplexity.
There was but one thing to do, namely, to make our way back, for a landing there was quite impossible, scarcely anything being distinguishable save a small winding stream. Besides, I was without knowledge as to whether the wind had changed since I had left the farm. It probably had.
Suddenly, flying as low as I really dared, I struck out a little to the south making a complete circle of Stockhurst, but avoiding Mayfield. I had no desire to rouse the town again by the noise of my exhaust, for in those days of Zeppelin peril the throb of aircraft engines was always alarming, and more especially at night.
Three times did I circle round, but failed to attract Teddy's attention.
Suddenly Roseye nudged me and pointed eagerly down to the left. Her quick eyes had detected a tiny white light showing, which looked like short and long sparks.
My heart gave a bound. Yes, it was Teddy!
Yet we were now so high again, to avoid the surrounding hills, that his flash-lamp only looked a tiny point of light.
He flashed some message in Morse, but I only got a few letters.
Would he repeat it? We both watched breathlessly, as I headed the machine in his direction.
Yes!
Again the light spoke in the 'longs' and 'shorts' of the Morse code, which both Roseye and I could understand.
Together we read it.
'Return in an hour,' he signalled.
Why? I wondered. What could have occurred?
Somehow, by the appearance of his light, I thought he must be signalling in secret, and not in the open.
He would expect some acknowledgment from me, telling him that I understood.
Therefore I elevated our searchlight so as to shine upward, instead of below. Then, touching the lever, a long beam of white light shot skyward for a second.
Afterwards I shut it off, and made straight away due southward by the compass, greatly puzzled.
What could possibly have happened?
