This he secured firmly in position, and then, having set the fuse, he began to return, through the water, to his starting place. Another swift flash illuminated the leaves of the riverside bushes. It was followed by a second thundering explosion, as another bomb burst near the crowded troop train which still had not crossed the bridge.

In a few minutes he clambered up the bank and hurried through the magic beauty of the moonlit wood. He reached the edge of the field where he had landed, and stood waiting. He looked at the luminous face of his watch. The pilot was going to allow him fifteen minutes. Fourteen had pa.s.sed. He knew his friend would not fail him whatever happened, so though he stood, soaking wet and alone, surrounded by the now angry enemy, he did not feel at all alarmed.

Overhead he heard the drone of the engine, which suddenly stopped, to be followed by the faint, scarcely-heard hiss of the wires as the machine began to glide downwards to the ground. Soon a shadowy shape moved swiftly across the ground and stopped. The observer ran over to it and climbed quickly into his seat. He shouted to the pilot of the success of his operation, and then with a roar and rush was borne upwards, and to his relief found himself flying swiftly once more through the friendly air.

Even as they turned to start on their long homeward journey a great sullen roar rose to them from below, and they saw that no more across the silver streak of the river lay a black line, for now it was obscured by a cloud of smoke, which slowly dissipated and revealed a great gap in the bridge, near which was the red glow of the locomotive that no longer could take forward its carriages loaded with troops destined for a now impossible railhead.

That happened in the early days of the war. Swiftly developed the powerful arm of the air. Great were the changes in thought. Mighty the new weapons of destruction....

"C.O. wants to see you at once in the Mapping Office."

It is four o'clock on September 29, 1917.

I hurry to the little hut by the mess and pa.s.s through the door. Over the long desk leans the grave-faced squadron commander, the great pioneer of night-bombing. With a pencil and a ruler he carefully studies a map.

"Is that you, Bewsher?" he says. "Look here, I want you to go to Namur to-night; do you think you can do it?"

"I think so, sir."

"Well! Look! It is a hundred and twenty miles the other side of the lines. There is a big railway bridge there--the Luxembourg bridge--here--see! That is the only railway bridge for a hundred miles of the river. If it is put out of action the German lines of communication are badly broken. The Army H.Q. are very keen on it. It is a great chance for the squadron--and a great chance for you. Brackley will be the pilot. You had better go to see him. How are you going to find the way?"

"Know the way up to Ghent, sir; shall go by landmarks after that!"

"Hum! Take my advice and fly by the compa.s.s, and only use landmarks as a check! Well, you will see!"

Now ensues three frantic hours of activity. I hurry off to see Brackley, who has just returned from leave, and at twelve o'clock was in Dover.

The time of preparation is one series of kaleidoscopic pictures--of crawling inside a machine unfamiliar to either of us: of being taught the operation of a new petrol pressure system: of watching the loading of the four huge 250-lb. bombs, fat and yellow, which I have never before had the opportunity of dropping: of drawing a line from Dunkerque to Ghent, from Ghent to Namur, across the long green-and-brown map: of pondering the patches of the forests, the blue veins of the river, and thinking how in a few hours they will appear for me in reality, lying below in the moonlight, etched in dim shades of black and dull silver: of a strange dinner in the mess when semi-seriously, semi-facetiously I write out my will, leaving to one friend my books, to another friend my pictures: of having the doc.u.ment properly witnessed, and rushing out amidst cries of good luck: of the lonely dressing in leather and fur in my little hut: of the roar of the engines as we rise up at latest twilight towards the glittering companies of the stars.

It is a quarter to eight. Eight thousand feet above the coast near Dunkerque we move. My pilot is a senior officer, and I have never flown with him before, so I sit quietly and do not talk, as I watch carefully the dials of my petrol instruments, and also keep a careful eye on the country below. The pilot looks at the engines with a satisfied glance, and the machine swings round and points east.

Soon the dim pattern of the Dixmude floods lie below, reflecting the gleam of a quivering star-sh.e.l.l. In the sky above Thorout appears a dazzling Very's light which drifts and dies--German machines are abroad in the darkness also. Far below now lies Thorout, and for a minute or two its pale beam waves vainly and impotent in the moonlit sky, its strength so dissipated that it is useless. Soon south of Ghent we move, and see to our right the landing lights of the huge Gotha aerodrome of Gontrode.

I stand up and look across the pilot, and count the lights.

"Eight on each side--two red at the west!" I say.

"I make it more," he comments. "Count again!"

I make sure of my accuracy, and draw in my note-book a detailed sketch of the landing arrangements.

"Look!" cries suddenly the pilot. "We've been heard!"

I peer down once more and see only the two red lights glowing on the ground. The two lines of white electric lamps have been switched off, for the drone of our engines has been heard high above the aerodrome.

Suddenly I realise that we will be heard through the whole of our long journey. The absence of searchlights and sh.e.l.l fire in these undefended regions makes one forget that from town to town, from village to village, the report of our progress is sent to a thousand military centres in a vast radius. Already our pa.s.sage into virgin territory (for not for years has country east of Ghent been bombed at night) must be causing a sensation. Brussels must be apprehensive: Aix-la-Chapelle is feeling anxiety: Cologne is uneasy.

Now ahead of us I can see what never before have I seen--the lights of villages shining clearly in scintillating groups here and there across the pale moonlit country. With my map on my knees I pick up and check every railway and crossroad and forest below me in turn, and manage to keep the machine exactly over the line marked on the map.

"We're all right, sir!" I say to the pilot. "See this straight road on the map. There it is--there--see! See that forest crossing it--well--there it is! I am quite sure of our position. We come to a river soon ... look! look! do you see it--that silver streak over there?"

The pilot nods, looks at my map, and turns on the bright engine lights in order to examine the dials. To my slight discomfort he leaves them on as he flies ahead, evidently feeling confident of our safety.

Far ahead I can see a light flashing and flashing in a regular code. I presume it to be near Brussels, and point it out to the pilot. In a few minutes through the slight haze of the distance appears a great number of twinkling lights, and soon to our left I see a vast sea of glittering, shimmering gems, with lines of lights radiating outwards from it like the tentacles of an octopus. I suddenly realise that it is Brussels, and with a cry of utter delight stand up to look down more clearly at it. It is a wonderful spectacle. There, in one wide sweep before my eyes, lies the whole city, triumphantly blazing out into the night. I can see the long lines of the boulevards stretching through the ma.s.s of lights, on the outskirts of which glitter little villages, from which also radiate the lines of street lamps, as though illuminated starfish lay here and there across the country. _Brussels_--_Brussels_, beats through my brain as I see the Belgian capital, feeling safe in its remoteness from the lines flaming bravely in the darkness. I live through one of those rare moments of divinity which come to men when they see before them for the first time some sublime spectacle which perhaps has never been seen before.

In the middle of the town there flashes an aerial lighthouse. This is rather puzzling, as the German night-bombing aerodromes are many miles to the west, near the coast at Ghent and Bruges. I wonder for whom this light flashes and blinks. Then I suddenly realise that perhaps one of the infrequent Zeppelin raids is being carried out against England on this wonderfully clear night.

Brussels pa.s.ses. Road and forest and village flow beneath us in a regular and expected stream. Slowly the minutes go by. Ten minutes to ten says the watch. For over two hours we have been in the air, and our engines show no signs of wavering. On them alone now depend our chances of return. Soon I see far ahead of me the silver ribbon of the Meuse shining in the haze of the horizon, and then the lights of Namur, cold and sparkling, appear by the side of the river. I examine every tiny landmark on the ground below, and check it with my map. There is no doubt. There lie the lights of the town--there lies the forest on its outskirts--there lie the two bridges, from one of which the thin black line of the railway trails off into the distance.

"Namur!" I say to the pilot.

He looks down and flies round in a wide circle in order to examine every point, and to ensure for himself that no doubt whatever exists as to the ident.i.ty of the place. He is quite satisfied, and turns the machine towards the south-east. We cross the river south of the town as I explain to him my intentions. I want him to turn north-west, against wind, and to throttle the engines. We will glide down parallel to the railway line, which will help me to get a good line. We will reach the bridge at a low alt.i.tude, and I will drop my bombs. We will turn quickly down wind to escape.

Before I crawl into the back I point out to him some very bright lights in the direction of the Namur Zeppelin sheds, which seem to confirm my supposition of the activity of German airships to-night. Then, with a final word of explanation, I stoop through the door behind my seat and lie on the floor of the machine. I slide open the little trap-door beneath the pilot's seat, and see a small square picture of moonlit country. Ahead there is just visible the curve of the river, and the black line of the bridge across it. Beneath me runs the railway track which is to be my guide. To my joy I can see, at one place upon this thin dark line, the intermittent red glowing of an engine's fire-box. In a swift moment I realise the actuality of the country below. For a second it ceases to be a map and becomes peopled with busy human beings.

Oh, Namur (think I), ablaze with lights, you enjoy this moonlight night of late September, far, far from the turmoil of war, little conscious that overhead this very moment lies a fur-clad airman peering down at you, preparing to drop his terrific missiles, packed with fierce explosive! Laugh on in your cafes, you exquisitely-clad German ambusques! For me this moment is rich and ecstatic. Then the difficulty of the task absorbs my mind. The noise of the engines has ceased.

Through the machine sounds the faint rush of wind hissing and sighing round the tight-strung wires and planes as we sink lower and lower. My bomb-sight draws nearer and nearer to the bridge. Pressing the b.u.t.tons of the direction indicator I steer the machine to right and left, as green or red glow the lights before the eyes of the pilot. The direction bar touches the bridge and drifts off to the left. I swing the machine round quickly, again the bar crosses the bridge, again it drifts off. We are flying slightly side to wind, and I can scarce keep the head of the machine on a straight course. The pale-glowing range-bars draw nearer and nearer, with a slow progression, to the black edge of the silver river. Again I press the right b.u.t.ton; again a green light glows; again the machine swings towards the bridge. The range-bars cross the base of it. I press over the bomb handle quickly, ... and again.

Clatter--click--clatter--click--click--clatter sound the opening and closing bomb doors behind me as bomb after bomb slides out into the moonlight depths below. For a moment I see the fat yellow shapes, clear-lit in the pale light beneath me, go tumbling down and down towards the dim face of the country.

I hurry back to my seat beside the pilot.

"Half dropped, sir. 'Fraid they will not get it. Oh! I am sorry, sir! I am sorry! We drifted!"

One, two, three red flashes leap up in the water of the river some hundred yards to the south of the bridge. One, two more flashes, more rapid and brilliant, leap up on the moonlight embankment, leaving large white clouds of smoke.

"Jolly good! You didn't miss by much!" he says encouragingly.

Boom--boom--BOOM--boom--BOOM! sound the five explosions as we turn. It is strange to look at Namur--still sparkling beautifully with a wealth of light under the stars--still unchanged, though we know that the thundering clamour of these five unexpected explosions must have stirred up the placid life of the little tranquil town till it is seething like an ant-hill upset by the wayside. In the squares and streets must run the alarmed population, rushing to and fro aimlessly, utterly terrified.

In the military headquarters the telephones and telegraphs must have burst into a sudden activity. The vibrant roar of the explosions must have been heard for a great distance. Even in remote Aix-la-Chapelle the strolling Germans must have wondered at the far-away sound drifting to them under the stars.

Again we fly to the south: again we turn and start on our second "run"

over the target: again I crawl into the back, steeled this time by a great anxiety and a great determination, for I realise the enormous responsibility which is mine. With the five remaining bombs behind me I have, if possible, to destroy the great railway bridge, which to me will appear only a small black match laid across the silver ribbon of the river. If the bridge is destroyed or damaged the German communications will be vitally interfered with, the moving of their troops will be interrupted, the pressure on the British lines will be relieved. If I fail, that much-desired relief will not take place, and therefore many more British soldiers may be killed. That is not all, however--for failure means that this expensive raid is wasted; the reputation of the squadron is tarnished; the official approval of Handley-Pages as long-distance night-bombers is reversely affected; and, least of all, though of great importance to myself, my splendid opportunity for a great achievement is lost. With this sense of responsibility weighing heavily on me I lie down, peering through the little square hole. My face is wet with the perspiration of anxiety in spite of the intense cold of the biting wind: my hands shake with excitement. I decide to take the machine to the river along the railway line, and slightly to the east of it, and then to judge the wind drift so that the machine is turned by it to the left, when I will press the starboard signal b.u.t.ton and swing the machine at an angle across the bridge, and then drop my bombs. It is a great risk, and unless I judge exactly I will not succeed.

In a fever of apprehension, and with my whole being concentrated on the relation of the fine wires and bars of my bomb-sight with the black thread of the railway far below me, I lie on the varnished strips of wood on the floor of the machine, my legs flung wide apart behind me, my bare hands and face frozen with the icy blast of wind, my uncovered eyes running with water. Nearer and nearer to the bridge draw the two range-bars. Gently and rarely do I touch the starboard signal b.u.t.ton, to swing the machine again and again to the right as the wind drifts it to the left. We are near the bridge--we are almost over it. I press the starboard b.u.t.ton determinedly, and I see the glow of green light illuminate the dashboard. To the right swings the machine. White glows a light as I press the central b.u.t.ton. I look below quivering with anxiety. The machine ceases its leftward drift and swings to the right, and the two luminous range-bars are in line with the bridge. I grasp the bomb-handle and once, twice, press it over. I look behind--the bombs are all gone. It is all over! The irrevocable deed has been done! The failure or success of the long raid is sealed. I climb clumsily to my feet and look through the door beside the pilot.

"All gone, sir, I ... Oh! look, _look_!"

Upon the thin black line of the bridge leap out two great flashes, leaving a cloud of moonlit smoke which entirely obscures one end of it.

"Oh--d.a.m.n good--d.a.m.n good!" yells out the pilot excitedly. "Hit it! _Hit it!_ You've hit it! Oh--priceless--priceless!"

"Good--oh, sir! I am glad. It is. .h.i.t, isn't it, sir? Two of them. I _am_ bucked!"

Almost crying with joy we shake hands, and he thumps me cheerfully on the back.

"Something for you for this when we get back!" he says. "Oh! d.a.m.n good--d.a.m.n good, Paul. Priceless--priceless!"

I look round, and in the back of the machine I see a sight which left the clearest image of this raid in my mind. There stands the moonlit figure of the tall good-humoured gunlayer, and with a characteristic gesture I see him put out his arms with the thumbs pointing upwards--the most sincere expression of congratulation he can deliver. My heart goes out in grat.i.tude to this solitary man who already, for nearly three hours, has stood alone on a thin platform in the back of the machine, watching and eager, knowing that he has no control over his destiny, that his life lies in the hands of the little figure whose black head he can see so far away from him in the nose of the machine.
